homogeneity is also an important criteria for primary impact crushers. In primary impact crushing process, the physical size of the crusher feed opening must not be considered as the true gauge to set the maximum crusher feed size and - as a result of that - assess that any lump passing through the crusher feed opening has the correct feed size.
dust collecting in primary crusher. Controlling and minimizing exposure to silica dust requires proper wet dust suppression for rock crushers. Because water has a relatively high surface tension (72 dynes per cm), it alone cannot penetrate crushed material that releases silica dust.
Impact crushers can be used as primary crushers, secondary crushers or tertiary crushers depending on the size and technology. They are equipped with beaters, also called hammers, and impact plates. They operate in the following way they are fed from the upper part, then the stones are hit by the hammers and projected towards the plates.
For primary crushing with a reduction ratio of 6 to 1. When a relatively coarse product is desired, top size usually larger than 38 mm (1 1/2) Closed Circuit Crushing System To control top size from a single crusher operating in an open circuit, material must remain in the crushing chamber until the material is reduced to top size.
The primary impact crusher offers high capacity and is designed to accept large feed sizes. The primary impact crushers are used to process from 200 t/h up to 1900 t/h and feed sizes of up to 1830 mm (71) in the largest model. Primary impact crushers are generally used in nonabrasive applications and where the production of fines is not a problem.
There are three main steps in designing a good crushing plant process design, equipment selection, and layout. The first two are dictated by production requirements and design parameters, but the layout can reflect the input, preferences and operational experience of a number of parties.
