As an important equipment in the screening industry, the screening effect of vibrating screen not only has a great impact on the value of the product, but also directly affects the efficiency of the next operation. In actual production, when the dewatering screen can not reach the set processing capacity and the efficiency is low, how to improve the screening efficiency of sand dewatering screen?
Although the screening effect mainly depends on the nature of the screened material, different screening effects can be obtained by using different types of screening equipment for the same material.
In the actual production, according to the specific situation, on the premise of meeting the requirements of product particle size, the surface of nonmetallic screen with larger mesh size, better screening area and higher mesh opening rate should be selected, and the suitable mesh shape should be selected to increase the screening capacity and screening efficiency, and the work efficiency of material particles.
The reasonable selection of vibrating motor is one of the key factors affecting the performance of large dewatering screen, and the exciting force is the core factor affecting the productivity of vibrating screen.
As the vibration source of vibrating screen, vibrating motor should have the advantages of reasonable design, simple structure, compact structure, high excitation efficiency, energy saving, convenient installation and debugging. The selection of vibration motor includes working frequency, large exciting force, power and other parameters.
There is an exponential relationship between productivity and exciting force. With the increase of the exciting force, the productivity increases rapidly, while the blockage rate decreases rapidly with the increase of the exciting force.
The exciting force also has some influence on the passing rate and crushing rate of the screen, and its variation law is wavy: if the exciting force is too small, the passing rate and crushing rate are poor; If the exciting force is too large, it will increase the friction between the eccentric blocks at both ends of the screen shaft and vibrate the motor. In the case of high-speed rotation, it is easy to damage the motor and reduce the service life of the motor. Therefore, it is important to reasonably adjust the larger exciting force.
