Vertical roller mill is one of high efficiency calcite powder making mahcines. Use vertical roller mill to process calcite powder has lots of advantages. The advantages as follow:
Low noises and little dust: no direct contact between the grinding rollers and grinding plant, so metallic impact is avoided and its noises are 20~25 decibels lower. Totally closed negative pressure operation has employed in this vertical roller mill, so there is no dust during the operation.
High grinding efficiency: save 20~30% power consumption compared with the ball mill. With the increasing of moisture content, it can save more and more electricity.
Strong drying capacity: dry and grind raw materials with moisture content as much as 15%.
Low wears rate and little metallic pollution: its metal wear is only 5~10 g/t.
Mutifunction: crushing, drying, grinding, separating and conveying.
