Primary Crusher

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.

Diamond Mining Methods | Diamond Museum Cape Town

Diamonds are recovered from ore in 5 stages: Stage 1 – Crushing. Once the diamond bearing ore and gravel is collected, it is transported to a primary crusher. The primary crusher is responsible for reducing the size of the ore into smaller, more manageable pieces or chucks measuring no larger than 150mm.

Our Projects

To cater for a diverse range of ore types, Roy Hill''s existing crushing facilities included two trains: jaw crusher for harder material and primary & secondary sizes for softer materials. BGER identified that the existing arrangement could be optimised catering for all ore types within a single gyratory crusher feed by vibrating grizzly.
