With the continuous advancement of domestic industrialization level, people have higher and higher requirements for the fineness of powder, an intermediate product used in manufacturing, which inevitably requires the use of a grinding production line.

The grinding production line mainly includes production lines of crushing equipment, grinding equipment, and screening equipment. Its function is to continuously refine bulk materials into small particles to produce powder that meets the specified fineness.

According to the nature and particle size of the bulk materials, select the appropriate main production equipment, including crushers and grinders. Among them, the crushers can be jaw crushers, impact crushers, roller crushers, etc. For situations where the crushing ratio is large, you can choose to set up two-stage crushing. Generally speaking, the jaw crusher is more suitable for coarse crushing and should be set at the first level of crushing. The impact crusher is suitable for medium and fine crushing and should be set at the second level of crushing so that it can ultimately meet the requirements for entering the grinding equipment.

Grinding equipment is the core equipment of the production line. The more commonly used ones include ball mills, rod mills, vertical mills, etc. The feed particle size of the mill is generally required to be small, about 25mm, depending on the grindability and output requirements of the material. , Grinding method: Choose appropriate grinding equipment. Taking ball mill as an example, the grinding method is divided into dry method and wet method, and the discharging method is divided into center discharging and peripheral discharging.

The fineness of the material after dry grinding can be well controlled through a powder separator. Generally, a grid mill is used. Its advantage is that the material is forced to be granulated, which helps to increase the output of the mill. The powder selector can realize online powder selection. Materials that meet the requirements are collected directly. Materials that do not meet the standards are re-entered into the ball mill and ground again until they are qualified.

Wet grinding cannot carry out powder selection operation. Generally, center overflow discharge is used to extend the grinding time of materials in the mill, so that the fineness of the materials reaches the standard. In wet grinding, the materials have good fluidity under the action of water and are more evenly distributed between the grinding bodies, which is beneficial to increasing the output and reducing 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 are determined based on the output of the main equipment.
