As experience shows, when one determines the energy-power parameters of crushing and grinding processes by using the existing methods, the power of motors used in drives of existing crushers of various types often turns out to be excessive [10, 11].In this case, the drive will operate at a relatively low load (ratio of the power consumed by the …

The primary coal crushers may be of different types such as: (1) coal jaw, (2) coal hammer, and (3) ring granulator. Secondary coal crusher: Used when the coal coming from the supplier is large enough to be handled by a single crusher. The primary crusher converts the feed size to one that is acceptable to the secondary crusher.

Primary crushers with crush run-of-mine rock from blast product size to what can be carried by the discharge conveyor or fit/math the downstream process. A typical example of primary crushing is reducing top-size from 900 to 200 mm. In Selecting a primary crusher you need to worry about these requirements:

Primary Crushing. The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m; Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate: 160 to 13,000 tph

Plus, primary crushing is super important for the whole crushing and processing thing. How well it's done really matters for both the cost and the quality of what we end up with.
