Background
The solid material is separated according to the required particle size by sieves with different mesh sizes. Often, the combination with crushing makes the particle size of the crushed material nearly equal to ensure that certain requirements are met or excessive crushing is avoided.
Mine screening is the process of separating loose materials into different size fractions through a screen, and is called ore screening. In the concentrating mill, screening is mostly combined with the seed testing industry. The passing classification of which the granularity is qualified before the ore enters a certain section of a crusher is called pre-screening. The crushing device can prevent the excessive crushing of ores and improve the production efficiency of the crusher. After the ore is crushed by the powder crushing machine, the granularity of the crushed ore is measured by a screening gun, so that the unqualified and overlarge ore particles are returned to the crushing operation for crushing again, and the screening is called as inspection screening. In the actual production process, the screen mesh is extremely easy to damage and difficult to replace, and meanwhile, the environment is polluted by the large dust in the screening process.
