This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types grid type ball mill and overflow type ball mill.
Overflow ball mill is a kind of ball grinding mill which works in wet water state. It belongs to a type of wet ball mill and is a very common grinding equipment in the concentrator. Ball grinding mills are classified according to the discharge methods and can be divided into overflow ball mill and grate ball mill.
The ball mill grinding media is generally spherical or small cylindrical steel cylpebs, the material can be steel, ceramic, glass, and even rubber. Because ball mill grinding media of different materials and sizes can be selected, the ball mill machine can be used to grind.
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
