Working principle of spiral classifier

Author:


The spiral classifier is mainly composed of feeding port, spiral shaft, classification chamber, discharge port and other parts. The material enters the screw shaft through the feed port, and then moves forward along the screw shaft under the push of the screw shaft. In the process of movement, the material will be subjected to centrifugal force and gravity, showing a different state of motion. The heavy particles move outward and the light particles move inward, thereby achieving the classification of the particles.
The working principle of the spiral classifier is to use the centrifugal force and gravity of the particles in the process of rotation, so that the particles are separated according to the density and size. By reasonably setting the speed and angle of the screw shaft, the classification effect of the classifier can be adjusted to make the particle size of the scored material more uniform.
In addition to play an important role in the classification process of granular materials, spiral classifier also has the characteristics of simple structure, stable operation and convenient maintenance, so it is widely used in chemical industry, building materials, food, medicine and other industries.
In general, the working principle of the spiral classifier is to classify particles by means of centrifugal force and gravity. Through reasonable design and operation, effective classification of materials can be realized, production efficiency can be improved, and costs can be reduced.
