The greater the reduction in size during subsequent crushing stages from primary, secondary to tertiary crushing, the higher the emissions. Primary jaw crushers produce more dust than comparable gyratory crushers because of the bellows effect of jaw and because gyratory crushers are usually choke-fed, thus minimising the open spaces from which

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).

Vertical shaft impact crushers. Vertical shaft impact crushers take the full advantage of so-called rock-on-rock crushing process. In vertical shaft impact crushers, the crushable material is fed through the centre of the rotor, where it is accelerated to high speed before being discharged through openings in the rotor periphery.

Impact crusher for sale is a crushing machine that uses impact energy to crush materials. It can crush all kinds of coarse, medium and fine materials (granite, limestone, concrete, etc.) whose feed particle size does not exceed 500mm and compressive strength does not exceed 350MPa and is widely used in various ore crushing, railways, highways, energy, cement, chemical, construction, and other

Impact crushing. Impact crushing is essentially like opening a walnut with a hammer – when the hammer meets the shell, the nut instantly cracks into a number of smaller pieces. Mining equipment creates impacts by using a rotor to violently hit and throw rock against the walls of a crushing chamber.

Impact crushers are traditionally classified into two main types, horizontal shaft impact (HSI) crushers and vertical shaft impact (VSI) crushers. These different types of impact crushers share the crushing principle, impact, to reduce the material to smaller sizes, but features, capacities and optimal applications are far from each other.
