The primary impact crushers are used to process from 200 t/h up to 1900 t/h and feed sizes of up to 1830 mm (71") in the largest model. Primary impact crushers are generally used in nonabrasive applications and where the production of fines is not a problem. Of all primary crushers, the impactor is the crusher that gives the best cubical product.

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.

The most common types of crushers include Jaw Crushers, Gyratory Crushers, Cone Crushers, ... Jaws and Gyratories are more often used as primary crushers, while Cone Crushers, known for providing a good product shape, are often used for downstream crushing to refine the product size. Roll Crushers, Impactors and …

Jaw crushers can be divided into two basic types, single and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation, along with the toggle plate, causes a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...

They can be used in primary or secondary crushing applications. They excel at handling feeds with clays and other contaminants that are problematic for Jaw Crushers, Gyratory Crushers and Impact Crushers. Mineral Sizers are also ideal for underground operations where height and access are restrictive factors for other forms of primary crushers.
