The screening process is just as important as the crushing itself. Screens are the hub of every rock processing plant. They are used to classify materials both in different stages of the crushing process and in final product separation.


designing our products based on a needs analysis, often identifying vital factors that even the client wasn't aware of. This is the reason why Meka crushing and screening plants and concrete plants are preferred in regions with widely varying environmental and geographical conditions, such as England, Ecuador, Siberia, Chile, the Comoro Islands,


12%Abstract. Crushing and pulverizing reduces the material to a uniform size, or to a graduation of sizes for immediate use or further processing. The various manufacturers make specialized crushers for various processes, such as reduction of long coils of metals into short lengths, reduction in size of run-of-mine coal down to one inch and under in one operation, …


Primary crushing is used to reduce the size of coarse materials, such as clays, down to approximately 1 to 5 centimeters. The most common types of crushers used are jaw crushers, cone crushers, gyratory crushers, and roll crushers. Secondary crushing or grinding reduces particle size down to approximately 1 millimeter in diameter.
