Application
Overflow Ball Mill is widely applied in mineral classification, cement, fireproof materials, glass, ceramic, chemical industry and so on. It can grind all kinds of rocks and grindable materials. There are two ways of grinding: the dry process and the wet process.

Features and Benefits:
1. Overflow Ball Mill is an efficient tool for grinding many materials into fine powder.
2. The Overflow Ball Mill is used to grind many kinds of mine and other materials, or to select the mine
3. Overflow Ball Mill is widely used in building material, and chemical industry.
4. There are two ways of grinding: The dry way and the wet way.
5. Overflow Ball Mill can be divided into tabular type and flowing type according to different expelling mine
6. To use the Overflow Ball Mill, the material to be ground is loaded into the neoprene barrel that contains grinding media.
7. As the barrel rotates, the material is crushed between the individual pieces of grinding media that mix and crush the product into fine powder over a period of several hours.
8. The longer the Overflow Ball Mill runs, the finer the powder will be.
9. Ultimate particle size depends entirely on how hard the material you' re grinding is, and the time how long the Overflow Ball Mill runs.
10. Our Overflow Ball Mills have been used to grind glass, powder food products, create custom varnishes, make ceramic glaze, powder various chemicals

Overview
Overflow ball mill is made up of feeding part, discharging part, gyre part, transmission part ( reducer, small transmission gear, motor, and electrical controller) and so on.
The hollow axis of the ball mill adopts the cast steel, and the lining can be replaced. The big rotary gear is forged from cast rolling gears.
The barrel body of our ball mill is inlaid with wearable plates.

Overflow ball mill working principle:
Overflow ball mill is horizontal type and tubular running device, has two warehouses. This ball mill is grid type and runs along the outside gear. The material enters spirally and evenly the first warehouse of the milling machine along the input material hollow axis by input material device. 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 ball mill produces centrifugal force, at the same time, the steel ball is carried to some height and falls to make the material grinding and striking. After grinded coarsely in the first warehouse, the material then enters into the second warehouse for regrinding with the steel ball and scaleboard. In the end, the powder is discharged by output material board and the end products are completed.
