Industrial rotary screen, also known as a rotary screening machine or drum screen, is a device that screens materials through a rotating screen. It uses the rotating motion of the screen to separate materials according to particle size to achieve the purpose of grading and separation. It is a screening device widely used in industrial production.
What is the working principle of the industrial rotary screen?
The working principle of an industrial rotary screen is mainly based on centrifugal force and the rotating motion of the screen. The material enters the screen from the feed inlet and is screened on the screen under the action of centrifugal force. Larger particles of material will roll outward along the radial direction of the screen, while smaller particles of material will be screened out through the pores of the screen. The screening effect depends on the size and shape of the pores of the screen, as well as factors such as the particle size and humidity of the screened material.
What are the main components of industrial rotary screens?
1. Motor: Provides power for the rotary screen and drives the screen to rotate.
2. Reducer: Reduces the speed of the motor so that the screen rotates at an appropriate speed.
3. Screen drum: a cylindrical structure that holds the screen and supports its rotation.
4. Screen: a screening surface with different pore sizes and shapes, used to screen materials.
5. Feed inlet: the entrance for materials to enter the interior of the screen.
6. Discharge port: the outlet of the screened material, usually divided into multiple outlets to collect materials of different particle sizes.
Application areas of industrial rotary screens
1. Mineral industry: used for crushing, screening, and grading of ores.
2. Building materials industry: used for screening of building materials such as sand and cement.
3. Chemical industry: used for screening of chemical products such as limestone, calcium powder, polymers, potassium chloride, etc.
