Vibrating screen is a kind of sieving equipment used for grading and screening materials in various fields: such as minerals, quarry, building materials, water conservancy and hydropower, transportation, chemical industry etc. Nowadays, people more and more attention to energy saving and emission reducing, improve efficiency is also an important factor for energy saving and emission reducing. In this article, we mainly introduce some effective ways to improve the screening efficiency of vibrating screen.
1. Choose Suitable Vibrating Screen
Even though the screening efficiency of vibrating screen is mainly decided by the properties of raw materials, but if we adopt different types of vibrating screen to screen the same raw material, the screening efficiency are different. So we should choose suitable vibrating screen according to the physical properties of raw material in order to improve the screening efficiency. For example, for pre-screen and check screen of raw materials, we can adopt circular vibrating screen. Besides, in order to improve the screening efficiency, we should choose vibrating screen with relatively large mesh size on the premise of meeting the requirement about the final products size.
2. Properly Choose Vibration And Adjust Vibration Force
Choosing proper vibration is one of the key factors that affect the performance of vibrating screen. And the vibration force is the key factor affect the screening efficiency.
As the vibration source of vibrating screen, vibration should feature reasonable design, simple and compact structure, high vibrating efficiency, energy saving and easy to install etc. While choosing vibration, we should take the following factors into consideration: working frequency, max vibration force, power etc.
The production rate of vibrating screen will increase along with the increasing of vibration force but the blocking rate will decrease along with the increasing of vibration force. The increasing of vibration force leads to the increasing of vibration strength. In this case, the force on raw materials also increases, the speed of raw materials get faster, which will increase the screening efficiency and reduce the blocking rate. So properly adjust the vibration force means a lot for the screening efficiency of vibrating screen.
