Comminution by gyratory crusher is the first stage in the size reduction operation in mineral processing. In the copper industry, these machines are widely utilized, and their reliability has become a relevant aspect. To optimize the design and to improve the availability of gyratory crushers, it is necessary to calculate their power and torque …
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 ...
Some materials are considered too hard for Roll Crushers and may need to be tackled by a Jaw, Impactor or Gyratory crusher. ... practice to size the width of the rolls to 1-1/2 to 2 times the size of the largest feed lump even though the capacity requirement of the application may be lower than what the crusher can produce.
location of the crusher in a mine imposes a number of requirements on its design and parameters; primarily they are related to overall dimensions and explosion safety issues. One of the promising options is using single-roll gyratory crushers [2]. Figure 1 shows a cross section of the working chamber of such a crusher. Figure 1.

The largest gyratory crushers in current use attain throughputs of over 6000t/hour and have feed openings 1500mm x 4400mm in size (A x B), while the discharge graps range in width from 150 to 250mm. A jaw crusher designed for a certain throughput rate can accept larger pieces of rock than the normal gyratory crusher.
The three most common compression crushers are jaw, gyratory, and cone crushers. Cone and gyratory crushers are similar in operation and lubrication requirements. Before discussing the primary compression crusher lubrication points, it is suggested that all electric motors bearings be correctly lubricated with a suitable grease.
Figure 1 shows a simplified section of a typical gravity fed gyratory crusher.
