Zenith Vertical roller mill used in the construction of cement grinding station

Divided by cement production process as cement clinker factory, grinding station and the

preparation of four types of plants. Grinding station, including: cement grinding,

homogenization and preparation of cement, cement and bulk packaging manufacturing processes

of enterprises. LM series is mainly used for a variety of vertical roller mill slag, limestone,

barite and other minerals in the milling process.

Increasingly widespread use of slag, fly ash will be used in its powder form.

Therefore, all new cement mill grinding station to be considered in the end, the former

library located slag cement (or fly ash) and slag powder library (or fly) measurement scale,

in order to match with a cement mill by “all” of post- into the cement silo. This will not

only improve the quality of cement, but also a significant increase compared with production

of cement grinding station. LM series roller mill cement grinding station core equipment in

recent years in product quality, equipment, process, technology, etc. are improved to some

extent the construction of the cement grinding station to resolve the problems.

Grinding station’s location is important, because vertical roller mill with a certain

degree of particularity and facilities, LM series of vertical roller mill manufacturers free

of charge to help users Zenith crime scene, the production process, on-site supervision of

installation and equipment operation training. Zenith vertical roller mill technical

personnel proposed to establish the general mining area near the raw materials of cement

clinker production line, in the vicinity of large and medium cities is close to the sales

market for the establishment of cement of cement grinding station, thus reducing

transportation costs. If the clinker production line built around the city, due to about 1.6

tons of clinker per tonne of raw material, we need a 60% increase in transportation costs.

Conversely, if the grinding station and clinker production lines with built near the mining

of raw materials, most of the mixed wood waste generated by the city, these hybrid materials

to be transported to the cement plant was built near the mine, the grinding into cement and

then transported to urban use, increased transportation costs. Therefore, in the grinding

station building near the city has its social and economic benefits to save transport costs.

So, in recent years, many cities around the establishment of a cement grinding station.

Roller mill cement grinding station is the main process equipment, LM series of strong

vertical roller mill crushing, crushing, high efficiency, and running stability. To a

certain extent, reduce the power consumption or increase the system output, to a certain

extent to solve cement production is low, running instability concerns. Also in the process

is concerned, relative to the closed circuit grinding mill is only open process save some

investment, maintenance and management convenience. But the closed-circuit grinding easy to

adjust, change and water quality of raw materials adaptability stronger. New grinding

station, from a number of companies to buy clinker clinker production, the clinker

grindability must be different, this time closed-circuit
grinding mill production and the fineness of

cement for easy adjustment and changes little advantage over open ground. Some recommend the

use of open-circuit grinding process of the experts believe, because the
cement mill grind open process with

closed-circuit grinding wider than the particle size distribution, and thus lower water

demand for normal consistency, concrete mixing station welcome. Choice of which method, the

cement plant can be based on the actual situation of their own choice, LM series of vertical

roller mill of the two processes are not strictly required.

In fact, the options have their pros and cons, there is not a perfect solution, the

key is when the owners to choose the goal must be clear. Select the program to be considered

advanced and mature, but also consider the quality of employees can fit. Such as the one to

save tons of cement from the lower operating costs, power consumption, the choice of the

final vertical roller mill grinding system is certainly the most advanced. On the current

level of technology, consider the grinding station has a running cost advantages and to

ensure the quality of cement, endorsed grinding station should be closed-circuit grinding

roller press + form grinding process.

The Notion Collective, Station Identification

Check out these internet radio images:

The Notion Collective, Station Identification

Image by Northern Spark
Station Identification is an interactive exploration of the Twin Cities’ radio landscape, which will be broadcasting (and receiving) live radio feed from the Foshay Tower observation deck. WNYC, KNOW, KCRW, KUT, KEXP, WHYY, WWOZ, WBEZ, WOLX, WORT — these are letters that may mean nothing or everything to you depending on where you’ve lived and what you’ve listened to. As radio call signs, they can be as much a part of a city’s landscape as lakes, rivers, skyways, and freeways are.

Station Identification explores this relationship by transforming the Foshay Tower’s observation deck into a radio compass. Each radio’s placement corresponds to the direction that station is broadcasting from, providing audience members a connection between what is playing and where it is sourced. Walking through the space — an open-air deck encircling the tower’s peak — is like scanning the radio dial with your feet.

Additionally, Station Identification welcomes participants to respond to their experience using a temporary Internet radio station located on the deck. Accessible at: n.otion.co/si, we are broadcasting live throughout the night, both participants and remote listeners can tune in to this radio programming inspired by and made, in part, for its very own location.

Office chairs – Make the work station comfortable


by skoop

Office chairs are available in wide range in market. Right selection of furniture’s can beautify your office environment.

Furniture plays a vital role in beautifying the look of your home or office. But if you have selected furniture only for style then it may harm your body. Apart from style comfort is the main thing which has to consider while buying furniture. Office is the place where every people spend almost 9 to 10 hours daily. office chairs has much importance because a employee sits on the chair and do his work. If it will not be comfortable then the body posture will be affected and it will harm the employee. Uncomfortable chairs will also distract their mind from work and they will also not enjoy their work but if it will give them comfortable they will feel the place like home and will enjoy their work to a large extent. Many manufactures have designed office furniture’s in different styles, designs and colors.

In office different types of furniture’s are used like for employees there is different style, for conference room its different and the same for guests and reception. The work station of employees is designed in two ways that is cubical style and bay style. In cubical style four employees can sit together but their privacy is maintained because it is divided by walls from three sides in the fourth is left free for entry and exit of employees. Nobody can disturb anyone in this. In bay style there is a stretched desk where all the employees work in a single row. The seating arrangement is done in such a manner that everybody can communicate with each other.

The person who has the responsibility of buying furniture’s should keep certain thing before buying. Firstly the height of chair should match the height of employee so that that he can comfortably do his work. Then comes the color selection, it should not be very bright that pinch the eyes, very eye soothing and decent color is best for office purpose. One more thing that is also importance is the style of chairs; it should be very stylish like you keep at home. Office furniture’s should have a decent look.

You should never compromise with the chairs quality; it should be strong enough to manage anybody’s weight. Some manufacturers offer much cheap office furniture which are easily affordable to anybody. So keeping these things in mind always select the right furniture for your office and make it look better.

DVB Digital station logo subtitles into the system is pre-made icons or text message a good selection of MPEG-2TS plug into the flow of program Video Image, the television network company to achieve station logo, insert a business angle standard or subtitles. DVB digital station logo into an existing way to achieve three main types: subtitle mode, the whole series full explanation of the method, the local decoding method.

Which, subtitle the most simple way, without adding new equipment, disadvantage is STB Must support the subtitle decoding, and many special effects station sign subtitles can not be achieved.

Way the whole series all solution to the original analog station logo CG Improvement. Namely: the reduction of the current digital signal into an analog signal, analog sets standard way to join the CG station logo or title, then translate digital signals. This approach has the advantage of mature technology, low cost, disadvantage is the need to decode – the process of re-encoding, signal a loss.

Local codec is totally based on digital signal processing method. TS stream directly to the video to change the macro block pixel hybrid DCT frequency domain calculation, in the TS stream to station logo, flying characters, weather, angle standard, Animation , Back-up pictures embedded. Advantage is not treated, some of the original signal will not be any impact will not be signal loss, disadvantage is the higher skill level required, the higher the cost of the corresponding.

Coding algorithm essentially, through the process of compressing video signals. In the larger of the compression ratio will cause a small amount of signal loss. Is a lossy compression.

The station logo subtitles machine, the best approach is to insert a station logo or title of the regions of partial treatment, so that will not affect the overall quality of the picture. The whole solution in the whole series of products is once again the signal decoding and encoding, the process will lead to signal loss again. Especially the repeated “decoding – code”, the signal loss is particularly serious.

In addition, you can see from the chart, the Taiwan standard CG and encoder, multiplexer is a series of relationships. So, if TS stream full decode – re-encoding, the entire TS stream signal quality will depend on the encoder and the station logo in the coding performance subtitle machine both the weaker party. The general solution in the whole series products are mostly all options are based on server or IPC soft coding, the coding results are far inferior to the professional encoder. So, will result in decreased overall signal quality.

The following, on the whole series full explanation of the method, the local decoding means to achieve these two technologies means of a simple contrast.

Whole series full explanation of the method. ASI card inserted by way of industrial control computer, according to the number of configuration ASI card device can determine a way or a few road shows to station logo insert subtitles. To configure an ASI card, for example, processing steps are:

1.’s A way to input TS stream multiplexer.

2. On the need to insert a set of programs to decode.

3. The decoded analog signal station logo or title of the insert.

4. To complete the insertion of the analog signal to encode.

5. To complete the program and the other untreated into the program as a way to re-multiplexed TS stream. Output.

The device in achieving the station logo subtitle insertion, on the TS stream to demultiplex, multiplex, on the program within the TS stream to decode, encode. Because for each of the CAO can not be undermined, the price is the deadweight loss of the original signal quality. TS streams on the one way to select a set of programs for station logo subtitles into relatively simple. However, if you want to stream TS on a road all the programs from the station logo to insert subtitles and its treatment will be very complicated.

Efficient Fpga Multiplier Used In Wireless Base Station (figure)

Based on WiMax and its derivatives in emerging broadband wireless standard protocol requires higher and higher throughput and data rate. These agreements made fast chip rate and digital radio processing program can use the FPGA hardware to achieve the best.

FPGA is very suitable Cooperation High-performance, cost-effective solutions to achieve these numbers in the physical layer protocol functions, as they include a wealth of resources:

1.DSP module can be used to achieve a variety of FIR filtering and FFT / IFFT operation of adders and multipliers required / accumulator functions;

2.SERDES transceiver, can support the wireless front-end and baseband digital board between the CPRI and OBSAI interface;

3. FPGA embedded RAM block important memory (EBR), can be used to store filter coefficients, perform block interleaving and FEC decoding to achieve (Turbo, Viterbi, Reed-Solomon, etc.);

4. Speed LVDSI / O, respectively, from the ADC and DAC support to a wide parallel interface. These converters are defined RF / analog functions and low-cost digital baseband logic between the boundaries. Interface, the higher the rate, low-cost FPGA solution that can integrate more statistics on the frequency / digital down conversion function.

This article focuses on the first resource that DSP multiplication module. Multiplication by reducing and optimizing DSP FFT and FIR in the module implementation, designers can minimize the use of resources to meet the throughput requirements under, allowing users to use the most cost-effective ready-made FPGA devices. The following four types of multipliers saving techniques in this introduction.

Functions for efficient complex multiplication WiMaxOFDM

WiMax system design, an important feature is to support orthogonal frequency division multiplexing (OFDM). FPGA makes use of IFFT and FFT, respectively in the discrete time realization of OFDM transmitter and receiver become particularly vulnerable. Such as 802.16a and other agreements require 256 samples of the FFT. The 802.16e The agreement calls for a variety of FFT samples, or the flexibility to adjust the FFT samples to meet the dynamic channel and bandwidth requirements (Extensible OFDMA).

Complex multiplication In the implementation of the FFT 256 and 1024 samples, the Radix-4 structure can be the most efficient use of multipliers. FFT Algorithm 4 samples by multiplex Discrete Fourier Transform (DFT) butterfly structure decomposition. For example, a 16-point FFT can be extracted by time, by taking or other related frequency decomposition method with two Radix-4DFT structure to achieve. Level 1 4 4 samples from the DFT composition, level 2 4 4 o’clock from the same DFT component. Since the output of each DFT requirements before the next level in the feed for the results presented provide three phases factors, so the first 1 and level 2 the phase factor between the needs of 9 9 complex multiplication.

First glance, the implementation of a complex multiplication requires four multipliers and two adder / subtractor. However, the expression can be re-written in another only three multipliers, three adders and two subtraction expression. It is noteworthy that the adder is the core logic in the FPGA implementation, using a rich bit by bit into bit mode (ripplemode) generic programmable logic unit (PLC) chip.

If D = Dr + jDi is the plural of data, C = Cr + jCi are complex coefficients, then the standard complex multiplication expression as follows:

E1: R = D * C = (Dr + jDi) * (Cr + jCi) = Rr + jRi (1)

Where Rr = Dr * Cr-Di * Ci, Ri = Dr * Ci + Di * Cr

These standards require the use of four multiplier expression. The expression can be re-order algebraic methods to:

E2: Rr = Dr * Cr-Di * Ci (2)

E3: Rr = Dr * Cr-Di * Ci +0 (3)

E4: Rr = Dr * Cr-Di * Ci + (Dr * Ci-Di * Cr) – (Dr * Ci-Di * Cr) (4)

E5: Rr = (Dr * Cr-Dr * Ci + Di * Cr-Di * Ci) + (Dr * Ci-Di * Cr) (5)

Complex expression is the result of the new:

E6: Rr = [(Dr + Di) * (Cr-Ci)] + (Dr * Ci-Di * Cr) (3 times multiplication) (6)

E7: Ri = Dr * Ci + Di * Cr (reuse the product from the Rr) (7)

Shown in Figure 1, the optimal complex multiplication can be three multipliers, three adders and two subtractor realized. It is noteworthy that, in the FPGA, the addition / subtraction module relative die area used is less than 18 Ã? 18 multiplier module.

Figure 1: The 4 and 3 multipliers of complex multiplication.

The Brave Defence of The Mission Station at Rorke’s Drift

Rorke’s Drift is situated 46 km southeast of Dundee and is the place of certainly one of the most well-known conflicts in the Anglo-Zulu war of 1879. The area in and around Rorke’s Drift is unspoilt and relaxing. Irishman James Rorke had originally set up a trading post almost 1 mile from the drift (crossing point) on the Buffalo River and was known to the Zulu warriors as KwaJimu (Jim’s place). Later, a mission station had been established by the Reverend Otto Witt of the Swedish Missionary Society. Witt built up a little church, mission house and livestock kraal at the foot of a rugged hill which he called Oskarberg.
Lord Chelmsford, had ‘requisitioned’ Rorke’s Drift prior to his traversing of the Buffalo River. He employed the house as a hospital and the chapel as a storehouse. All through the battle it was used as a medical facility. The defence of the mission station of Rorke’s Drift quickly followed the British Army’s loss at the Battle of Isandlwana earlier on the morning on 22nd January 1879. The devastating Zulu attack on Rorke’s Drift came rather close to defeating the little garrison, and the British accomplishment is held as without doubt one of history’s best defences. The 11 VCs given for valour at Rorke’s Drift are more than for any other military action of all time.

As Lord Chelmsford, the commander-in-chief of the British military in Natal, crossed into Zululand on 11th January 1879, his forces set up camp on the other side of the Buffalo river, 10 miles to the east, underneath the mountain at Isandhlwana. Three columns crossed into Zululand, from the Lower Tugela, Rorke’s Drift and Utrecht respectively, their goal being Ulundi, the Royal capital of the Zulus. On 9 January 1879 the middle column under Lord Chelmsford appeared and made camp at Rorke’s Drift.

On the morning of 22 January 1879, the main Zulu impi launched an attack on the British camp at Isandlwana. Lord Chelmsford had taken part of his force off in an alternative direction searching for the Zulu army. Hopelessly outnumbered, the British and local forces were slaughtered by the Zulu warriors with only close to 50 men get away alive. The remainder of the 1,000 strong force died. Later on that day, over four thousand zulu warriors commanded by Dabulamanzi attacked the small garrison of the 24th Regiment at Rorke’s Drift. These Zulu warriors had not been involed in the fighting at Isandlwana and wanted to prove their courage in battle. Cetshwayo had explicitly directed his Zulu warriors from crossing the Buffalo River which acted as the border between Natal and Zululand. Irrespective of this order, the Zulus grabbed the weapons off the bodies of the British dead and made for Rorke’s Drift. It was manned by 97 ready troopers, housed 36 wounded, 14 valuable natives, 5 officers and two lieutenants, one of which was new to the region. The Battle of Isandlwana was arguably the most humiliating defeat in British colonial heritage and only hours later that day, at Rorke’s Drift, 139 British troops defended their position against an intensive assault by more than 4,000 warriors.

Something that is nearly always disregarded is that the Battle at Rorke’s Drift could actually have concluded in the same devastating way as Isandlawana, but for one particular critical factor: Rorke’s Drift was a depot, so the British troops who defended it were able to make use of a near limitless source of ammunition. It is believed that somewhere between 20,000 and 25,000 rounds were fired in the course of the defence of Rorke’s Drift, the overwhelming majority of the rounds having missed their targets entirely and so, conservatively speaking, each and every 25th shot fired by the men of Rorke’s Drift led to an ultimate Zulu death, and each 50th shot was a kill shot. The British knew the Zulu warriors were on their way however they elected to stand and fight. Wounded men would had to have been laden onto horse-drawn wagons and Zulus would quickly have engaged them in the open. Instead, they opted to fight on ground of their choosing.

Together with having numbers that crushed a force five times bigger hours earlier, the Zulu warriors also had the Martini-Henry rifles captured off the British dead, presenting them an even larger advantage against the British.

Henry Hook plus 5 other privates were instructed on the afternoon of 22nd January to defend approximately 30 patients not able to be transferred away from the temporary hospital at Rorke’s Drift . Defensive lines were constructed connecting the 2 complexes â?? the hospital and the store room. Inside this border, an additional line of defence was built between the two structures and this was significant during the battle. The Zulus attacked the hospital setting fire to the roofing. Hook and others struggled for several hours, actually digging through walls and eventually getting virtually all out of the hospital and over to the inner defensive line near the store. Wave after wave of warriors with spears and rifles crashed against the makeshift lines of defence at Rorke’s Drift. The conflicts raged all night and by morning the British defences still held strong and the Zulu warriors in the end withdrew.

Following seeing the aftermath of Isandlwana, Chelmsford believed that Rorke’s Drift had fallen and it was only the sound of cheering from the garrison convinced him . eleven VC’s were awarded to the defenders of Rorke’s Drift. Colour Sergeant Frank Bourne was among five men to be awarded the Distinguished Conduct Medal and the unusual honour of a commission. Having said that, his army pay was his only money had he believed he could not financially afford to become an officer thus declined the offer. Fittingly, he was the last survivor of Rorke’s Drift to pass away on 8th May 1945 â?? VE Day. Lieutenant-Colonel Frank Edward Bourne OBE, DCM was 91 years old.
