Mine screen is a common
screening equipment, mainly used for screening and classifying granular materials such as ore, coal, building materials and so on. The following is a detailed introduction to the mine screen.
Equipment structure:
Mine screens usually consist of the following main parts:
Screen box: The screen box is the main structure of the mine screen, usually made of welded steel plates. There are multiple layers of screens inside the screen box for screening materials of different particle sizes.
Vibration motor: The
mining screen uses the excitation force generated by the vibration motor to vibrate the screen box and promote the screening of materials on the screen.
Screen: The screen is a key part of the mine screen and is used to screen materials. Screens are usually made of metal wire or polymer materials with different hole sizes to adapt to the screening requirements of different granular materials.
Support device: The support device is used to support and fix the screen to ensure the stability and working effect of the screen.
Feeding device: The feeding device is used to evenly put the materials to be screened into the screen box to ensure even distribution of materials during the screening process.
working principle:
The working principle of the mine screen is to use the excitation force generated by the vibration motor to vibrate the screen box, so that the materials are screened and classified on the screen. The material enters the screen box from the feeding device. Under the action of vibration, the finer particles fall through the aperture of the screen into the discharge port below, while the coarser particles are blocked on the screen and are finally discharged through the discharge port. .
Application areas:
Mine screens are widely used in mining, metallurgy, coal, building materials, chemical industry and other industries to screen and classify granular materials. Specific applications include:
Ore screening: Ore screens are often used for preliminary screening of ores to divide the ores into different grades according to different particle sizes to provide suitable materials for subsequent mineral processing, grinding and other processes.
Coal screening: During coal processing, mine screens can be used to accurately screen coal and classify coal according to particle size to meet the needs of different uses.
Building materials screening: Mining screens are widely used in the building materials industry to screen and classify sand, gravel, cement, concrete and other materials to ensure product quality and engineering requirements.
Chemical industry: In chemical production, mineral screens can be used to screen powder and granular raw materials to ensure product uniformity and quality stability.
