Ball mill

The ball mill is a key equipment for regrinding. It is widely used in the mining, new type building material, glass, ceramics and etc. According to different forms of discharging materials,it can be divided into tabular type and flowing type . And there are two ways of grinding :the wet process and the dry process. The wet process means that the materials are grinded with water ,while the latter not.

Structure Features

This machine is made up of feeding part ,discharging part,gyre part,transmission part(decelerator,small transmission gear,generator,electrical control )and so on .The hollow axis adopts the cast steel and the rotary big gear is processed from cast rolling gear .The barret body wears well and bears wearable scaleboard.

Working Principle

1) This ball mill,a horizontal type and tubular running device, has two warehouses. This machine is a grid type .The material enters spirally and evenly the first warehouse of the milling machine along the input material hollow axis by input material device.

2) In this warehouse , there is a ladder scaleboard or ripple scaleboard, and different specification steel balls are installed on the scaleboard, when the barrel body rotates and then produces centrifugal force ,at this time , the steel ball is carried to some height and falls down to make the material heavy striking and grinding .

3) After being grinded coarsely in the first warehouse, the material then enters the second warehouse for regrinding with the steel ball and scaleboard. In the end, the powder is discharged by output material board and the final products are completed.
