Impact crushers are commonly used to crush rocks with a silica contain under 5% such as coal, limestone, and phosphate. The only reason why you would use an impact mill/crusher or a hammer mill on a high-silica rock is because it might be sticky in nature and rich in clay. Such high abrasion/high silica impact/hammer crusher operation see

In the mining industry, the most common crusher types are jaw crusher and cone crusher. Jaw crusher is usually used for primary crushing, and cone crusher is used for secondary crushing. The material of crusher plays an important role in its working efficiency and service life. However, the regular operation and maintenance are important, too.

Producing such a fine crush generally requires multiple crushing stations of up to 4 being but as a minimum of 2 being oversized. The gape determines the maximum size of material that can be accepted. Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4

Impact crushers tend to be less expensive than compression crushers (aka cone and jaw crushers, which we already covered) and have a higher reduction ratio. They can also break sedimentary deposit-type rocks—limestone and similar—along natural lines, which rounds off sharp angles and weak edges. This can produce a result that is more sand-like in nature.

Typically the uncontrolled emissions from 200 to 600 tons/hr. crushers range between 1000 to 3000 kg./hr which after reduction by over 99% in dry type collection systems such as bag filters reduce to as low as 3 to 6 kg/hr. Impact on Water Pollution. Dry collection control techniques generate no water effluent.

“In a crusher, the crushing chamber is going around in a circle and the crusher is closing up in one location,” Dobler says. “Once you have segregation in that chamber, one side is coarse and the other is fine. Over time your components will feel that, and they will fail.” The same logic applies to impact crushers, Dobler adds.

Crushing is accomplished by compression of the ore against a rigid surface or by impact against a surface in a rigidly constrained motion path. Crushing is usually a dry process and carried out on ROM ore in succession of two or three stages, namely, by (1) primary, (2) secondary, and (3) tertiary crushers.
