Vertical Roller Mill Operation

Vertical Roller Mill Operation

Vertical roller mill is widely used in the cement industry raw materials, clinker preparation, grinding slag, ore, industrial silicon, carbide slag, coal gangue and coal chemical industry, power plant desulfurization, coal preparation and other areas of high efficiency Energy-saving grinding equipment.

Ore milling process design with a goal of an important indicator, related to the type of equipment, the number of selection and investment size. The vertical roller mill is the core of ore milling process equipment, the grinding effect is related to the powder rate, product quality and other economic and technical indicators. When the basic production and product mix to determine how the configuration of the mill after the most reasonable? Our company through the engineering design and technical transformation of the practice encountered in several different production but the process is roughly the same ore mill grinding machine selection to do comparison, analysis, obtained some of the output and milling machine match experience.

Effect of System Leakage on Mill Output

As the entire system is in a high negative pressure state, if the seal is poor, it will leak into a large number of cold air, thereby reducing the system wind speed and a corresponding increase in the system useless work to increase power consumption. Vertical mill feeding three-way valve and slag sluice lock wind device, electric dust zipper, the system duct flange junctions and other parts of the air leakage easily, it will cause the mill inlet and outlet pressure drop smaller, wind speed is not enough , The material can not be taken away in time, affecting the mill output. Also reduce the wind speed will result in the accumulation of pipe material, pipe accumulation of materials, the ventilation area will be reduced, the air flow will also affect the mill production. So timely check the air leakage problem is also necessary.

Influence of System Design on Output of Vertical Roller Mill

Vertical roller mill in grinding cement raw material operations, the general use of kiln exhaust gas on the material drying, therefore, the task of system design, in addition to determine the basic structure of the system form, but also by thermal calculation to determine Typical vertical roller mill operation parameters, supporting equipment specifications, and to develop the necessary process control means. According to material balance requirements to determine the amount of material entering and leaving the mill, evaporation and out of the mill the amount of wind, according to heat balance to determine the entropy of the wind into the wind, according to kiln and grinding air volume, the comparison of the results of the heat to develop the appropriate process measures.
