How it Works: Crushers Grinding Mills and Pulverizers

Shoe and anvil VSI crushers have composite metal alloy anvils positioned to maximize the impact of the material that is thrown against the stationary anvils via centrifugal force Comparisons with cone crushers have shown VSI crushers to be more energy efficient and also to produce more fine material under the same operating conditions and time frame

Bond Impact Crushing Work Index

Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper According to Bond 's Third Theory of Comminution the work/energy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product – the feed

Gyratory Crusher

A jaw crusher crushes only a small proportion of the original aggregate particles but an impact crusher crushes mortar and aggregate particles alike and thus generates a higher amount of fine material (O'Mahony 1990) Gyratory crushers work on the same principle as cone crushers (Figure 4 4(c))

Crushing in Mineral Processing

In mineral processing or metallurgy the first stage of comminution is crushing Depending of the type of rock (geometallurgy) to be crushed there are 2 largely different techniques at your disposition for crushing rocks In principle compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface
