The working principle of vibrating screen

When the vibrating screen is working, the two motors synchronously and reversely rotate to make the exciter produce a reverse excitation force, forcing the screen body to drive the screen to move longitudinally, so that the material on it is periodically thrown forward for a range due to the excitation force. So as to complete the material screening operation. It is suitable for screening sand and gravel materials in quarries, and can also be used for product classification in coal preparation, mineral processing, building materials, electric power and chemical industries. The working part of the vibrating screen is fixed, and the material is screened by sliding along the working surface. Fixed grid sieve is one of the most widely used in concentrators, generally used for pre-screening before coarse crushing or medium crushing. It has a simple structure and is convenient to manufacture.
