The primary crusher is used to reduce the size of the initial rocks, while the secondary crusher further breaks down the smaller pieces into finer materials. ... The design and operation of primary and secondary crushers also differ. Primary crushers are usually stationary machines, whereas secondary crushers are often mobile or semi …
The core of the Superior™ MKIII 42-65 primary gyratory crusher is the robust design. Resistant U-shaped arched spider, durable manganese bronze spider bushing, new shell separators and inspection ports, as well as hardy one-piece main shaft makes Superior™ MKIII primary gyratory crushers efficient and lasting, but easy to maintain when needed.
There are two main types of jaw crushers: simple-toggle and double-toggle. A single-toggle jaw crusher is simpler in design and is widely used because of its low cost and ease of maintenance. On the one hand, the double-toggle jaw crushers have a more complicated mechanism that creates a more uniform product size and a more efficient …
Gyratory crusher is generally used as a primary crusher. The crusher is popular due to its high throughput capacity and the large sized opening. The crusher is well suited for handling direct feed from haul/dump trucks. The gyratory crusher is mainly used in rock that is abrasive and/or has high compressive strength.
