To select mining equipment in the griddle, we must first understand the classification of screening machinery; structure and working principle; secondly to consider their respective advantages and disadvantages; then there are know their scope of application.
(1) Fixed Screen: Working part fixed and, by leaving the material sliding along the face materials are screening. Fixed grid screen is used more as a concentrator, generally used for rough, broken or in pieces before the pre-screening. It is simple structure, convenient. Does not consume power, the ore can be unloaded directly into the screen surface. The main disadvantage is the production of low screening efficiency is low, generally only 50-60%.
(2) roller screens: Face of horizontally arranged by the rolling axis consisting of a root, shaft has plates, fine-grained material from the gap between rollers or plates through.Bulk material from the roller-driven movement to and from the end of the discharge end.Rarely use this sieve concentrator.
(3) Cylinder Screen: Working part is cylindrical, rotating the screen around the cylinder axis, the axis is not in general downloading into the inclination. Materials from one end of the cylinder to the entry of fine-level work surface materials from the barrel through the sieve, coarse material discharged from the other side of the cylinder.Cylinder Screen speed is very low, smooth, good power balance. But its easy to plug the sieve screening efficiency is low, the work area is small, low productivity.Concentrator rarely use it to make screening equipment.
(4) plane motion screens: the body is wobble or vibration of a plane. According to the trajectory plane is divided into linear motion, circular motion, elliptical motion and complex motion. Shaking screen and shaker in this category.
(5) shaking screen: is the crank as the transmission components. Motor through belt and pulley drive eccentric shaft rotation, so that the body through the connecting rod for reciprocating movement along a certain direction. The direction of motion perpendicular to the body or suspension strut rod centerline, because the body of the swing movement, the screen surface material to a certain speed to move the discharge end, the material also be screening. Several sieve with the shaking screen compared to the relatively high productivity and screening efficiency. The disadvantage is the driving force is poorly balanced. Concentrator is now rarely used it, and be more structured shaker instead.
The most widely used in the concentrator, according to the different driving mechanism, but also can be divided into the following categories: Eccentric Vibrating Screen, Vibrating Screen, self-centering shaker, resonance screen
