Rotary screen
Working principle: The drum screen is composed of a cylindrical drum placed at an Angle, and the surface of the drum is provided with a screen of different specifications. The material enters from the high end of the drum, and with the rotation of the drum, the material rolls and slides inside the drum. Under the action of gravity and the centrifugal force generated by the rotation of the drum, the material that meets the aperture of the screen falls through the screen and becomes the material under the screen; The material larger than the screen aperture continues to roll in the drum until it is discharged from the low end of the drum and becomes the material on the screen. For example, when dealing with construction waste, the roller screen is constantly rotating to separate different particle sizes of masonry, concrete blocks, etc.
Scope of application: construction industry: often used to screen building aggregate, sand and stone, etc., can be graded for different particle size of stone, to provide suitable particle size of raw materials for construction projects. At the same time, it can also be used to deal with construction waste, and the bricks and concrete blocks are screened and recycled.
Mining: The preliminary screening of the ore can separate ore particles of different sizes, which is convenient for subsequent processing and crushing. For example, in coal mining, it can be used to screen coal of different particle sizes.
Agriculture: can be used for grain, seed screening, remove impurities and unqualified particles, to ensure the quality of agricultural products. For example, sieve corn, soybeans, etc., to remove impurities such as small stones and broken grains.
