Inclined Screen Although the crushing process is an important part in a plant, the screening quality and precision has the highest influence on the overall efficiency of all equipment.

There are three stages of screening, before primary crushing, scalping screens, before secondary crushing, primary screens, and product screens for lumps and fines separation. Ore grade is determined from the blasthole drill cuttings in the mine and sample cutters in the plant. Low-grade fines are rejected from the product and stockpiled.

Screening ahead of fine-reduction crushers is not only desirable, it is imperative from the standpoint of both safe and satisfactory operation. Preferably, all material smaller than the crusher-product size should be removed from the feed. There is an old saying to the effect that, "It is cheaper to screen than it is to crush," which is ...

Producing such a fine crush generally requires multiple crushing stations of up to 4 being but as a minimum of 2 being oversized. The gape determines the maximum size of material that can be accepted. Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape.
