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.
