Primary Crushing: To reduce large and bulky materials to a manageable size. Jaw Crusher: 500 mm to 800 mm: Reduced to about 125 mm to 150 mm. Large chunks of material are fed into the jaw crusher where strong compressive forces break them down. Secondary Crushing: To refine the size of the materials from the primary crushing stage. Cone Crusher ...
be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1.

Disadvantages of a Jaw Crusher. Jaw crushers can also have some disadvantages compared to other types of size reduction.
The machinery's high-impact movement typically relates to a high production rate in a primary crusher. For instance, a standard jaw crusher diagram might show a feed rate of 500 tons per hour, translating to processing massive volumes like 1200 cubic meters of limestone or iron ore in a single day—a testament to the machine's ...
The primary crusher is the link between chemical comminution (blasting) and the beginning of the mechanical comminution circuit (crushing and milling). The primary crushers take blasted, run-of-mine, or run-of-quarry feed up to 1500 mm and produce a product ranging in size from -300 …

These are bolts that have a known shear strength. If something that the crusher cannot crush accidentally gets into the crushing chamber these bolts will shear off when the Jaw hits the unbreakable object. This will prevent damage to the rest of the crusher. Unlike the gyratory crusher the main lubrication used on Jaw crushers is grease instead ...
No discussion of primary crusher selection would be complete without a comparison of the two leading types: the standard gyratory crusher and the Blake jaw crusher.
