Vertical mill’s working principle in the process flow of cement

Vertical mill with the advantages of high efficiency &output greatly improves the efficiency of process flow of cement production. Aiming at the cement production status and market demand, Guilin Hong Cheng launches a vertical mill with superior performance.

 1. Process flow of cement production

In simple terms, process flow of cement production is the overall process of cement raw materials being processed into cement finished product. For enterprises, understanding process flow of cement production can help them know the exact requirements in each process so that they can choose ideal equipment to create more profits.

Process flow of cement production consists of crushing , raw material preparation,raw material homogenization, preheating&decomposition, cement clinker firing, cement grinding and cement packaging. The grinding process which has direct effect on efficiency&cement finished product is a crucial process in process flow of cement production . Nowadays reducing energy consumption in the grinding process is a trend in cement industry. Choosing vertical mill with superior performance&low energy consumption is an important step to improve the efficiency&quality of process flow of cement production.

2. Vertical mill in process flow of cement production

Vertical mill which is an ideal equipment in cement industry has the advantages of large output and easy adjustment of grain size, it can meet the demand for large scale & multiple specifications production. In addition , vertical mill with larger output can reduce energy consumption by 40-50%, this standard is much higher than the national energy conservation standard.

Guilin Hong Cheng vertical mill not only has the aforementioned advantages, but also has the following  advantages:

 A: it is equipped with advanced PLC electronic system which can realize remote control of the materials and grinding process.

B: less material staying time in vertical mill and fewer times of grinding

C: it  is equipped with pulse powder collector which can realize 99.9% powder collecting rate under full negative pressure.

3. Cement vertical mill’s working principle

HLM vertical mill consists of mainframe,feeder,classifier,blower,pipes, storage hopper,electronic control system,collecting system etc.

The pressure device in HLM vertical mil is designed and produced by adopting standard modules,The number of rollers in the mill can be 2,3,4, or 6 at most, and the rollers can be installed by adopting the method of permutation and combination to use the fewest standard modules to  produce multiple series of products.

The motor drives the reducer to rotate the millstone, the materials which are pushed  to the space between rollers and millstone by centrifugal force are crushed,ground and smashed . Then the blower blows the powder to classifier , the large grain size powder falls down to reground and the fine powder goes into pulse powder collector and is blown out through the pipes as finished product, the purified air is blown out through the pipes  above the pulse powder collector.
