P&Q University Lesson 8- Screening | #Site Title

The bottom line is that crushers produce the material; screens separate the material; and screening efficiency affects the operation's overall performance. Screening is both art and science. The art of screening lies in the meticulous fine tuning, tweaking and synchronizing of screen setups within a near-limitless number of applications.

Jaw Crusher

The ore is to be broken down in a jaw crusher to pass through a 11.5 cm screen. The undersize is scalped before feeding to the jaw crusher. Assuming the maximum feed rate is maintained at 30 t/h and the shapes of feed and product are the same and the crusher set is 10 cm, estimate the size of jaw crusher required and the …

Gyratory and Cone Crusher

A primary gyratory crusher was required to crush iron ore at the rate of 3000 t/h. The largest size of the run-of-mine ore was 1000 mm. The required product size was less than 162 mm. Manufacturer's data indicated that the nearest size of gyratory crusher would be 1370 mm × 1880 mm with a cone angle of 18°.

Impact Crusher

The three types of crushers most commonly used for crushing CDW materials are the jaw crusher, the impact crusher and the gyratory crusher (Figure 4.4).A jaw crusher consists of two plates, with one oscillating back and forth against the other at a fixed angle (Figure 4.4(a)) and it is the most widely used in primary crushing stages (Behera et al., 2014).

Crushers

Having very similar features as the DT jaw crusher, the ST jaw crusher has slight differences. The maximum motion occurs at the top of the jaw and is created by an eccentric shaft. Due to the rubbing action of both the vertical and horizontal components of the jaw, the plate wear is accelerated and the power efficiency is lowered.
