Relaxation screen is a kind of screening equipment commonly used in the coal industry, and its main function is to separate and classify coal particles according to their size. However, for materials with fine particles such as slime, there is still some controversy about whether the relaxation screen is applicable.
Coal slime is a slurry material formed by mixing coal particles and water, and its particle size is usually small, which is not easy to separate by traditional screening equipment. In the screening process, the relaxation screen needs to rely on the relative movement between particles to achieve separation, and the adhesion and adhesion between particles in the slime will make it difficult for the particles to move freely, thus affecting the screening effect.
In addition, the slime contains high moisture, which makes it viscous and easy to clog in the sieve hole, which affects the screening efficiency. Relaxation screens are usually designed with an open-cell structure, which is not ideal for screening fine particles and highly viscous materials.
Therefore, for this special material such as slime, the traditional relaxation screen is not the best choice of screening equipment. In actual production, other screening equipment suitable for fine particles and highly viscous materials, such as vibrating screen, centrifugal screen, etc., can be considered to improve screening efficiency and sorting accuracy.
In general, although the relaxation screen has an important application in the coal industry, it is not suitable for the screening of special materials such as coal slime. When selecting screening equipment, it is necessary to select reasonably according to the characteristics of the material and the screening requirements to ensure the improvement of screening effect and production efficiency.
