With the continuous progress of domestic industrialization,powder fineness requirement is becoming higher and higher.It is necessary to use a grinding production line.

Grinding production line mainly includes crushing equipment,grinding equipment,screening equipment.Block material is constantly ground small particles and finally made into prescribed fineness of powder by it.

According to the nature and granularity of massive materials, you can select suitable main production equipment, such as crusher, pulverizing mill.You can choose jaw crusher, impact crusher, roll crusher, etc.If the material is large, two-stage crushing can be selected. Generally speaking, jaw crushing is more suitable for coarse crushing and it should be set in the first stage.Counterattack crushing is suitable for medium and fine crushing and it should be set in the second stage so as to finally meet the requirements of the grinding equipment.

Grinding equipment is the core equipment of the production line,ball mill, rod mill, vertical mill are more commonly used. The feed particle size of the mill is required to be small, about 25mm. According to the grindability of the material and output requirements, grinding mode to choose appropriate grinding equipment.Take the ball mill as an example, the grinding methods are divided into dry and wet method, and the discharge methods are divided into the central discharge and peripheral discharge.

The material that after dry grinding can be well controlled by powder selecting machine. The lattice mill is widly used. Its advantage lies in the forced granulation of the material, which is helpful to improve the output of the mill.Powder selecting machine can realize online powder selection and collect the material which meets the requirements directly.The unqualified material re-enter the ball mill again until qualified.

Wet milling can not select powder,so that it adopts the center overflow discharge and prolongs the grinding time of materials in the mill so as to make the fineness of materials up to standard.Under the action of water, the material of wet grinding has good fluidity and is more evenly distributed among the grinding bodies, which is conducive to the improvement of output and the reduction of the noise caused by the collision of the grinding bodies.

After the above main equipment is selected, other connecting equipment, conveying equipment and storage equipment shall be determined according to the output of the main equipment.
