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 are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills. Ball mill is an efficient tool for grinding many materials into fine powder. The ball mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material.
Ball Mill Features:
1.It is an efficient tool for grinding many materials into fine powder.
2.The ball mill is used to grind many kinds of mine and other materials, or to select the mine
3. There are two ways of grinding: the dry way and the wet way.
4. To use the ball mill, the material to be ground is loaded into the neoprene barrel that contains grinding media.
5.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.
6. The longer the ball mill runs, the finer the powder will be.
7.Ultimate particle size depends entirely on how hard the material you're grinding is, and the time how long the ball mill runs.
8.Completely enclosed welded design in high-grade steel.
- Direct drive via bearing journal with top-mounted gearbox.
Motor connected to gearbox via a V-belt drive.
- Product discharge via slots located around the periphery of the drum.
Working Principle of ball mill
The Ball Mills are a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished.
