vibrating screen exciter for horizontal and banana screener

Vibrating screen exciter drives the screen surface to produce high frequency reciprocating motion by means of mechanical vibration, so as to realize the rapid grading, screening or dewatering of materials.

Features of vibrating screen exciter:

1. High strength design: the body structure has been strengthened to adapt to the long time, high frequency operation environment;
2. Precision bearing configuration: standard with international brands (such as SKF or FAG) special bearings to ensure the stability and durability of the shaft system;
3. Adjustable vibration force: flexible adjustment of the size of the excitation force is realized by changing the configuration or weight of the eccentric block;
4. Modular installation: easy to replace and maintain, can be quickly integrated into different types of vibrating screen structure;
5. Multiple sealing structure: the use of labyrinth seal + mechanical seal double structure, effectively blocking dust, moisture, to extend the service life.

Technical advantages of vibrating screen exciter:

1. Stable operation, low noise: the use of dynamic balance optimization design, effectively reduce the vibrating screen running noise;
2. Long service life: bearing oil bath lubrication + anticorrosion process, adapt to high temperature, high humidity, strong dust and other harsh conditions;
3. Strong compatibility: can be matched with a variety of types of screening equipment, to adapt to different screen inclination and excitation frequency;
4. Enhance the screening efficiency: the dynamic performance of the exciter has a direct impact on the screening efficiency, scientific matching can significantly improve the yield and accuracy.

The working principle of vibrating screen exciter:

The shaker is usually composed of two counter-rotating eccentric shafts or eccentric blocks. Driven by the motor, the eccentric mass generates centrifugal force, forming a periodic excitation force, which makes the whole screen body vibrate in a fixed direction (linear or elliptical). Its vibration mode and frequency can be accurately controlled according to the needs of different working conditions, so as to optimize the trajectory and residence time of the material on the screen surface and enhance the screening effect.

Application areas of vibrating screen exciter:

1. Mining industry: used for ore, metal ore screening and dewatering;
2. Coal industry: for coal classification, desliming, de-mediation processing;
3. Building materials industry: such as sand and gravel aggregate screening, dust removal before processing;
4. Chemical industry and metallurgy: applied to screening, dewatering or pre-treatment link of bulk raw materials and by-products;
5. Solid waste treatment: municipal garbage, construction waste and other highly wet viscous materials in the grading and screening equipment.
