What are the characteristics of a flat rotary screen?

The flat rotary screen is also called a flat rotary screening machine or a fine screening machine. It is a high-standard screening machine. The flat rotary screen is currently the most effective screening machine that simulates the principle of manual screening motion. It can screen all fine and ultra-fine powders and particulate materials. It is particularly suitable for screening some materials that are not easy to screen. The screening indicators are several times better than those of general vibrating screens.
1. The structure of the flat rotary screen
The flat rotary screen is mainly composed of a screen body, a motor, a reducer, a base and other parts. The screen body is the main working part of the screening, which consists of a screen, a screen frame, a support device and the like. The screen is the core component of the screening, and its material and aperture size determine the screening effect. The screen frame is used to support the screen to ensure the stability and durability of the screen. The support device is responsible for hanging the screen body on the base and driving the screen body to rotate through the motor and the reducer.
2. Working principle of plane rotary screen
The plane rotary screen is also called reciprocating vibrating screen. The vibration force generated by its driving device is an inertial force that rotates around a fixed axis and changes in a certain regularity. Its essence is the reciprocating inertial force formed by the rotation of the eccentric wheel around the fixed axis. According to the structural characteristics and working principle of the gyratory screen, its screen surface is generally arranged horizontally or slightly inclined. The working principle of the gyratory screen is: after the screen machine is started, the screen machine shaking body, that is, the screen box, reciprocates back and forth under the action of inertial force, and the screen box drives the screen surface to shake periodically, so that the material on the screen surface moves in a directional jumping manner with the screen box. During this period, the material smaller than the screen hole diameter passes through the screen hole and falls to the lower layer, becoming the screen under the screen. The material larger than the screen hole diameter is discharged from the discharge port after continuous rolling and jumping motion, completing the screening work.
3. Characteristics of the flat rotary screen
1. Diversified structural design to meet different needs: There are two forms of fully enclosed structure and open structure. The advantage of the fully enclosed structure is that dust does not fly, it is environmentally friendly and energy-saving, and the running noise is also small; the open structure is mainly suitable for materials with larger particle size, and it is easier to control and operate the screening materials.
2. The screen utilization rate is high, the screening effect is good, and the original structure of the material is not damaged.
3. Large processing capacity, easy to use for assembly line production.
4. The screen replacement process is simple, easy to use, and the operation is balanced.
5. No pollution, low noise.
4. Application fields of flat rotary screen
1. Chemical industry: Flat rotary screens are often used in the chemical industry for screening of materials such as catalysts, pigments, and fillers to ensure that the material particle size meets the requirements and improve product quality.
2. Pharmaceutical industry: In the pharmaceutical industry, flat rotary screens are widely used in the screening of raw materials, the preparation of granules, and the screening of Chinese medicinal materials to ensure the quality and purity of drugs.
3. Food industry: Flat rotary screens are often used in the food industry to screen flour, starch, powdered sugar and other materials to remove impurities and improve food quality.
4. Metallurgical industry: In the metallurgical industry, flat rotary screens can be used to screen ore, coke and other materials to improve smelting efficiency and product quality.
5. Environmental protection industry: Flat rotary screens can also be used in environmental protection fields such as solid waste treatment and sewage treatment to screen and separate materials to achieve resource recovery and environmental protection.
