As an efficient and reliable screening equipment, abrasive classifier screen is widely used in various fields. In the abrasive industry, it can be used to screen and grade diamond, corundum, silicon carbide and other abrasives to improve the quality and use effect of abrasives. In the building materials industry, it can be used to screen and grade raw materials such as sand and stones to improve the quality and production efficiency of building materials. In the metallurgical industry, it can be used to screen and grade ore, iron powder and other raw materials to provide high-quality raw materials for the subsequent smelting process. In the chemical industry, it can be used to screen and grade various chemical raw materials to ensure the quality and effect of chemical reactions. In addition, abrasive classifiers can also be used in environmental protection, agriculture, food and other fields to meet a variety of different screening needs.
First, the principle of abrasive grading screen.
The principle of abrasive classifier sieve is mainly to use the mesh size of the screen to control the passage of abrasives of different specifications. When the abrasive enters the screen, the abrasives smaller than the mesh can pass through the screen, while the abrasives larger than the mesh are intercepted on the screen. By adjusting the mesh size of the screen, different specifications of abrasive screening and classification can be realized.

The abrasive grading screen is mainly composed of a screen box, a screen, a driving device and a discharging device. The screen box is the main body of the whole equipment, which is usually made of high-quality steel with good strength and wear resistance. The screen is the core component of the equipment, which is generally made of stainless steel wire or high-strength nylon wire and other materials, which has good wear resistance and corrosion resistance. The drive device uses a power source such as a motor or reducer to drive the screen to vibrate or rotate. The discharging device is the equipment that discharges the screened abrasives, generally using scrapers or conveyor belts.
3. Classification of abrasive grading screen.
Abrasive classifiers can be divided into many types according to different classification criteria. According to the working principle, it can be divided into vibrating screen and rotary screen; According to the structure of the screen, it can be divided into woven screen and laminated screen; According to the number of screen layers, it can be divided into single-layer screen and multi-layer screen; According to the drive mode, it can be divided into motor drive and hydraulic drive and other types. Depending on the application, the right type of abrasive classifier can be selected.
