The role of screening equipment in the beneficiation production line cannot be underestimated. They are used after crushing and before grinding to screen out the crushed materials that reach the grinding size, which are sent to the grinding equipment by the feeder. Those that do not reach the qualified size continue to return to the crusher for crushing. Therefore, the mining vibrating screen plays a connecting role and has a certain impact on the grinding efficiency. This article introduces four common types of vibrating screen for mining.
According to different weight grades, it can be divided into heavy mining vibrating screen, light precision vibrating screen and laboratory vibrating screen. It uses a single unbalanced weight excitation method to vibrate the screen box to make the screen surface incline, and its motion track is generally circular or elliptical.
The double shaft vibrating screen adopts double unbalanced weight excitation and synchronous opposite rotation to make the screen surface horizontal or gently inclined and move in a straight line. Vibrating screen types include inertial vibrating screen, eccentric vibrating screen, self centering vibrating screen and electromagnetic vibrating screen.
The screening efficiency is affected by many factors, mainly including 15% of material properties, 25% of operation, and 60% of screening equipment (screen surface parameters and motion properties)
- Linear mining vibrating screen
DZS linear screen has the advantages of stable vibration mode, low energy consumption and high screening accuracy.
The biggest feature of circular vibrating screen is that it can be multi-layer, strong exciting force, and high efficiency.
- Dewatering vibrating screen (referred to as dewatering screen)
They are used after crushing and before grinding to screen out the crushed materials that reach the grinding size, which are sent to the grinding equipment by the feeder. Those that do not reach the qualified size continue to return to the crusher for crushing. Therefore, the mining vibrating screen plays a connecting role and has a certain impact on the grinding efficiency. This article introduces four common types of vibrating screen for mining.
According to relevant research, in the whole screening operation, screening equipment has the largest impact on screening process indicators, up to 50%.
The screening efficiency is affected by many factors, mainly including 15% of material properties, 25% of operation, and 60% of screening equipment (screen surface parameters and motion properties)
- Linear mining vibrating screen
DZS linear screen has the advantages of stable vibration mode, low energy consumption and high screening accuracy. It is especially suitable for handling fine minerals, and can also be used together with hydrocyclones, which has higher and more sufficient dewatering efficiency, and can be widely used in tailing dry discharge, concentrate dewatering and other operations.
