Technical features of Dump Mill:
1.Low operating noise. By improving the inter design , we make the noise lowest.If you hear any big noise when the machine operating ,pleaes stop the machine and contact us to solve the problem.
2.High quality . We are the manufacturer of this machine ,we contral the quality from the begining we bought the materials to the end the machine were sent to you,so we confirm you the high quality products.
3.Factory prices. As we are the manufacturer , we sell the goods directly to the customers reducing the saling chanules which give the customers much benefits.
Working principle of dump mill:
When the cylinder is rotating, it lifts the materials and grinding media in it to a certain height. Under the action of gravity, the grinding media crush the materials like projectile. At the same time, the grinding media slide which also helps to grind the materials. In this way, the purpose of grinding is served.
On the basis of ball mill, there are three main characteristics of the wet mill, such as forced feeding, peripheral drainage and rubber lining.
Structural Property of dump mill:
(1) This wet grinding ball mill is single-chamber and center discharge ball mill.
(2) This wet grinding ball mill is composed of the working parts such as the feeding part, cylinder part and discharging part, as well as bearing part, driving part, electrical parts, basic parts, etc.
(3) The cylinder is made from steel plate. It contains wear resistant lining board and has manhole used to observe the abrasion conditions of lining board and grid plate, take out the grinding media, as well as replace the abraded lining board and grid plate.
