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.

Jaw crushers are a primary crusher used in mining, construction, and demolition recycling. Read more Imperial Metals Corporation
The crusher was born out of a need for a high capacity underground primary crusher that did not require a primary feeder, scalper, and the associated infrastructure therein. Minimizing the need for high cost stationary grids to control topsize underground was a requisite, and the large topsize acceptance was met with the UG design.
Approximately 50% of all underground limestone mines have their crushers located underground (NIOSH, 1999 which ) can be a major source of silica as well as nuisance dust. In this particular case study, the mine is considering different methods of controlling dust at their underground crusher using either a push-
Selecting the right crusher. Jaw crushers are the most common solution in underground applications when the throughput is less than 1,000 tons per hour, depending somewhat on the scalping solutions. Above 1,000 tph, primary gyratory crushers begin to look interesting, and after the throughput reaches 2,000 tph, jaw crushers are very rare, with

In an opencast or strip mining operation, the run of mine (ROM) material is normally transported to the primary crusher by haul trucks, and in underground mining operations it is conveyed to the primary crusher. Crushing equipment is important to the mining process because it reduces the use of precious excavated resources and eliminates the
Crushers play an important role in the material handling process for underground mine operations. The main purpose of a crusher is the size reduction of the feed. This size reduction is achieved by applying a force to the material, creating cracks in the material which in the end will cause the material to break into smaller pieces.

Mechanical haulage in metal mines is of four general types: (1) Locomotive, (2) scraper or slusher, (3) rope, and (4) belt conveyor. Locomotives for underground use are powered by electric, compressed-air, or, rarely, gasoline motors. Diesel locomotives have been used extensively in Europe, but have not been adopted in the United States.
