The screening process typically follows after comminution processes such as primary crushing and secondary crushing. There are different types of screens available. Some are grizzlies, vibratory, and wire mesh screens. Simply, the process of screening ore material is such that the material is passed through a screen

Both crushing and grinding require energy to reduce the ore size. However, in grinding operations we consume much more eneregy than crushing, up to 100 times ( thousands of kw compared to tens in crushing). Because as far as we go to finer size we need more force and collosions for further size reduction.

Screening is the process of separating materials before, during, or after crushing. The loose materials are separated into different levels according to the size of the particle through the sieve holes. Many types of vibrating screens are widely used in beneficiation plants, sand production lines, grinding production, or other industrial sectors.

Crushing and screening are straightforward mechanical operations that do not alter an ore’s composition, but some ores need to be upgraded before smelting. Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
