Working principle of spiral classifier

Author:


Spiral classifier is a commonly used granular material classification equipment, which is mainly composed of spiral shaft, casing, feed port, discharge port and other parts. When working, the material enters the spiral classifier through the feed port, and the screw shaft pushes the material forward and makes it rotate under the action of the screw. In this process, the material is subjected to the combined action of centrifugal force and gravity, and materials of different densities and particle sizes are separated. After classification, the larger and heavier particles will advance along the spiral axis, while the smaller and lighter particles will be pushed outside the spiral axis, thereby achieving the classification of particles.
The working principle of the spiral classifier is simple and efficient, and it is suitable for the classification of a variety of granular materials, such as ore, chemical raw materials, food particles, etc. At the same time, the spiral classifier also has the characteristics of simple structure, convenient maintenance, stable operation and reliable operation. In industrial production, the spiral classifier plays an important role and provides an effective solution for the fine processing of granular materials.
All in all, the spiral classifier has become one of the indispensable equipment in the granular material handling industry due to its unique working principle and convenient operation mode.
