Ball mill is used to break the materials, and crusher is also used to break the materials, so some people will wonder whether the crusher can replace the ball mill? Can it be replaced? Following is a detailed explanation.

The material handled by the ball mill is fine, and it is the key equipment for grinding the material after it is crushed. The grain size of the product handled by the ball mill is fine, up to 0.074 mm, even finer. The structural feature is that the broken parts contact each other, and the medium used is steel ball, steel bar, gravel or ore block, etc. But some machines are simultaneously crushed ore and grinding, such as autogenous mill.

The crusher can be divided into coarse crusher, medium crusher and fine crusher. Crusher generally handles large blocks of material, the product particle size is big, and usually more than 8 mm. Crusher is mainly used for crushing the original bulk material. It is widely used in the stone production line or in the ore crushing of the metal ore dressing. Ball mill is an indispensable equipment in metal processing. It is the equipment of further fine powder grinding after the material is broken by crusher. Under the ordinary situation, the ball mill grinds the material to 150 meshes or more before it stops, which is not replaced by crusher.

Therefore, crusher cannot completely replace the ball mill. Ball mill and crusher must be used in the mineral processing. But for the sand and stone production line, it is not necessary to use the ball mill, the jaw crusher, impact crusher, or vsi crusher can be used to complete the crushing process.
