Ball Mill knowledge

Ball Mill, a type of Grinding Mill, is a cylindrical device used to grind (or mix) materials like ores, chemicals, ceramic raw materials and paints. The Ball Mill is a key equipment to grind the crushed materials after the material were broken , and carrying on the smashing again. It is divided into two rubbing way-the dry and the wet .

The Ball Mill is a key equipment to grind the crushed materials, and the Ball Mill is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc, and the Ball Mill can grind various ores and other materials with dry type and wet type. There are two kinds of Ball Mill, grate type and overfall type due to different ways of discharging material.

Ball Mill is mainly composed of feeding section, discharging section, rotating section, driving section ( reducer, pinion, motor, electric control ) , etc. Quill shaft is made of carbon steel, with replaceable inner lining. Rotary gearwheel is processed with gear hobbing, with wearable linning plate in the shell to guarantee nice wear resistance. The machine runs stable in available working status. This machine run steadily and works reliably.

When the Ball Mill is working, 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. 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. 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. Powder shall be discharged from discharging grating, ending the milling process.
