Working characteristics
The eccentric block is used as the excitation force, which is strong.
The screen beam and screen box adopt high-strength bolts, with simple structure and convenient and fast maintenance;
Adopt tire coupling, flexible connection and stable operation;
It adopts the structure of small amplitude, high frequency and large inclination angle, so that the machine has high screening efficiency, maximum treatment, long service life, low power consumption and low noise.
According to the structure and working principle of screening machinery, there are roughly the following categories:
1. The working surface of roller screen is composed of one rolling shaft arranged horizontally.
2. The working surface of roller screen is composed of one rolling shaft arranged horizontally. The working part of the fixed screen is fixed, and the materials are screened by sliding along the working surface. Fixed grid screen is a kind of screen which is widely used in concentrator. It is generally used for pre screening before coarse crushing or medium crushing. The utility model has the advantages of simple structure and convenient manufacture. Without power consumption, the ore can be directly discharged onto the screen surface. The main disadvantage is low productivity and screening efficiency, which is generally only 50-60%.
3. The plane motion screen body swings or vibrates in a plane. According to its plane motion trajectory, it can be divided into linear motion, circular motion, elliptical motion and complex motion. Shaking screen and vibrating screen belong to this category.
