The air volume of the fan is an important factor affecting the fineness of the material. In the working principle of the vertical grinding mill, the air volume is an important factor to control the material flow in the internal circulation system. The volume of air will affect the speed of the powder.

Performance Evaluation Of Vertical Roller Mill In Cement, A conventional cement grinding circuit is composed of a two compartment tube mill a mill filter which collects the fine material inside the mill and a dynamic air separator where final product Grinding Mill Control Cement Finess In Vertical Mills
The cement vertical mill is a grinding equipment developed on the basis of similar grinding mills, so it has many irreplaceable advantages, such as high grinding efficiency, low power consumption (20-30% less power than ball mill), large drying capacity (simultaneously dry and grind materials with moisture up to 10%), large particle size of
At the time of production, the main engine speed of the vertical roller mill is controlled. For the operator, it is important to control the speed of the vertical roller mill's main engine. If the vertical rotation speed of the main vertical roller mill is too high or too low, it will
Increasingly modern cement plants also use VRMs for cement grinding. However, opportunities for the optimisation of VRMs are less obvious than with ball mills as all processes of grinding, drying, classification and regrinding take place within the body of the mill. Normal VRM control strategies Product fineness

Advanced process control for the cement industry. Vertical roller mill application Control challenges Among the operational challenges of a vertical roller mill are the fast dynamics of the process. Compared to ball mills with dynamics changing in 15-20 minutes, vertical roller mills have dynamics changing in 2-4 minutes.
2019-10-30 For a ball mill grinding OPC to a fineness of 3200 to 3600 cm 2 /g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15-0.20 EUR per ton of cement. For an chaeng vertical mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, i.e. whether hardfacing is applied.
What are the factors that affect the fineness of the finished slag vertical mill? News Date:2020-04-11 14:28:05. At present, the slag vertical mill is a common equipment for grinding ore, slag, blast furnace water slag and other materials on the market. Because of its powerful grinding and drying functions, it can meet the grinding needs of various materials, so it is widely used by users.
