The curve 1 relates to the ore size sample before crushing Fgo = 33 680 Eem and hardness Ai = 18.26 kWh/t, and the curve 2 relates to the ore size sample Fgo = 28711 m and hardness Ai = 12.47 kWh/t. In comparison, Fig. 6 shows the particle size analysis of industrial crushed ore after primary, secondary and tertiary crushing.
These finally crushed stones are again crushed according to the requirement of the customer. A single type of crusher is not sufficient enough to convert the large size rock into required size stone. So, the crushing process involves primary, secondary and tertiary crushers during the whole crushing cycle to achieve the required dimension.
Designed for crushing soft and medium-hard materials with close grain distribution and good cubical shape ratios, tertiary impact crushers are an excellent solution in the production of fine …
Best used for applications in primary, secondary or tertiary crushing, the NW Rapid™ plants can handle a capacity of up to 1,000 tons per hour. The design of this crushing and screening plant also comes with conveyors included.

Screening equipment is installed after the primary crusher, after the scrubber and after the tertiary comminution stage to separate the iron ore into a dry coarse fraction (8 – 40 mm) and a wet fine fraction (> 1 – < 8 mm).
Conveyor belts transport the crushed ore to the tertiary crushing circuit when it falls out of the cone crusher's bottom. Usually, this has another cone crusher or a high-pressure grinding roll (HPGR). The ore particles are reduced to around 6–12 mm in the tertiary crushing stage, which is ideal for the ball mills' subsequent stage ...
Run-of-mine ore is crushed and stored as "on-" or "off-grade" on blending stockpiles. Ore from the stockpiles is either sent to the wash-and-screen plants or, if "off-grade", to the beneficiation plants. The washing and screening plants consist primarily of tertiary crushing, washing, screening, conveying and stacking equipment.

The crushed ore obtained from the crushing stage is typically in larger size fractions and needs to be further processed through screening. 2. Screening. Screening is the process of separating the crushed ore into various size fractions. It involves passing the crushed ore through a series of screens with different-sized openings.
Screening is the passing of material through definite and uniform apertures is the only true and accurate means of grading to a required particle size. Air separation and hydraulic classification depend upon gravity and particle shape, and result in the segregation and retention of material of higher specific gravity and lower surface area irrespective of size.
