Product Application
Ball mill machine is a key equipment for crushing the materials after they are primarily crushed. It is widely used for the dry type or wet type grinding of all kinds of ores and other materials that need to be ground in cement, silicate product, new building material, refractory, fertilizer, black and non-ferrous metals and glass ceramic industry. The ore grinding methods of ball mill include dry type and wet type.
Ball mill machine is mainly composed of feeding part, discharging part, rotary part and driving part which includes reducer, small drive gear, electrical machine and electronic control. The hollow shaft adopts steel casting, the inner lining can be dismantled and changed, and the rotary rack wheel uses casting gear hobbing and inside the cylinder is wear-resisting lining board which has fine abrasionperformance. This machine has stable operation and reliable performance.

Working Principle:
1: Materials shall be evenly charged through quill shaft in feeding device into the first bin, which has step or waved lining with steel balls in different specifications.
2: Steel balls are taken to a certain height by centrifugal force from drum rotation and then fall. Thus it will give a heavy blow to materials, playing a role of grinding.
3: Materials after crushed in the first bin shall enter bin across single-layer diaphragm into the second, which is provided with flat lining with steel balls, to go through further grinding.
4: Powder shall be discharged from discharging grating, ending the milling process.
Features
1. Large application range, simple structure and convenient maintenance;
2. Large capacity and continuous work are obvious advantages;
3. Various barrel lining and grinding media, excellent corrosion resistance;
4. Installation and adjustment are very convenient and easy to operate.
5. Cylinder is rolled and welded with Q235B steel plate. (the steel thickness is generally 1/100 of the cylinder diameter, for example ball mill of diameter 1500, the steel plate thickness is 16 mm), the material of inlet and outlet hollow shaft is ZG35.
6. The hollow axis adopts the cast steel and the lining can replace, the rotating big gear processes in the way of casting rolling gear. The barrel body is wearable well and bears wearable scaleboard. This machine run steadily and works reliably.
