Cement Raw Material Vertical Mill
Performance Characteristics:
● High efficient grinding. Utilizing advanced material layer grinding principle saves 20-30% power compared to that of ball mill, meanwhile the energy-saving effect will be more obvious by the increasing of water content in raw material.
● Better drying capacity. It could take use wasted hot gas of kiln to dry the material, while it could dry and grind the raw material for the kiln with over 15% water content.
● HRM vertical mill takes up smaller area and its processing flow is simple. It is the equipment with the function of fine crushing, drying, grinding, separating and conveying, there is no need for equipping with drying, separating and lifting equipments. And its workshop area is only 70% of that for ball mill system, while its space is only 50-60% of that for ball mill system.
● Low noise, little dust emission, clean operation environment. Grinding roller and abrasive disk will not directly contact during operation that is to say there is no metal impacting, thus the noise is 20-25db less than that of ball mill system. The whole system utilizes complete sealed negative pressure operation, there is no dust emission, so the production environment is clean.
● Low abrasion, little metallic pollution for the products. Normally the metal abrasion is only 5~10g per ton production, thus the metallic pollution for the product is little.
● Roll sleeve of grinding roller could be turn over for using which could extend the useful life and cut down the production cost. And it’s operation and maintenance is convenient;
● The chemical content of grinding products is stable and the gradation of grain is even, this is propitious to calacine.
