Complete Rock Crusher Plant

There are numerous rock types in the natural wold. The main rock types processed by the crushed stone industry include limestone, granite, dolomite, traprock, sandstone, quartz, and quartzite. Other types of rock and stones include marble, shell, talc, barite and slate. Due to different properties, such as hardness and density etc., these rock can be classified into several catergories into hard, medium hard and soft rocks. Various rock crusher plants are available for crushing all these rock and stones.

Stone crushing operation can be proessed in three stages according to production requirements, including primary crushing, secondary crushing and tertiary crushing.

Selection of Rock Crusher Plants

When rock crushing circuit and stages have been designed, we can now start to select the correct crusher plant for each size reduction stage. Depending on operating conditions, feed size, capacity, hardness etc, there are always some options.

Primary crusher type

For soft feed (below Mohs5) a impact crusher is normally the first option if capacity is not too high. For harder feeding rock materials there is a choice between a gyratory crusher or a jaw crusher.

Secondary crusher type

In a rock crushing circuit, the second stage normally begins to be of importance for control of size and shape. Because of this the jaw crusher, in most cases, is not suitable as secondary crusher. Instead the impact crusher or cone crusher is used more frequently.

Also in comminution (crushing and grinding) circuits for ore and minerals the cone crusher is frequently used as the secondary stage. Using a secondary VSI crusher means as always a restriction in feed hardness.

Tertiary crushe type

Compared to other crushers the cone crusher has several advantages making them very suitable for size reduction and shaping downstream a crushing circuit. This is because of the crushing chamber and the possibilities to change feed and discharge openings during operation.
