Vertical roller mill is a kind of high efficient energy saving equipment, which is a single large production capacity, energy consumption of unit product is low, narrow size distribution of the products, high purity, good fluidity, vertical roller mill is a kind of superfine grinding equipment, production and processing has been widely applied in foreign white non metallic minerals industry, the current domestic scale non metallic minerals also tend to use the equipment technical process to produce the product of TSP, barite, limestone and other non-metallic minerals, through cooperating with ultrafine classification equipment and processing equipment, to achieve product fine production.
Several advantages of vertical roller mill:
Low construction cost:(1) the vertical roller mill has the advantages of simple process flow, and the milling system compared to the area can be reduced by about 50%, the construction cost is reduced by about 70%, a building area of small, less space occupation.(2) mill crushing, drying, grinding, grading conveying into a whole, simple, compact layout. Can open layout, the construction cost.
The drying ability strong, vertical roller mill using the gas conveying material, can control the air temperature in the grinding of the larger water material, make the products reach the final moisture content, on the vertical drying up to 12~15% of material grinding, even drying and milling, drying of the material is only for 3~4%. Environmental protection, energy saving; small vibration, low noise, little dust, clean operation environment, adapt to the demands of environmental protection.
