stone crusher used in quarry plant
Crushing is the first step of processing begins after the extraction from quarry or pit. Many of these steps also are common to recycled materials, clay, and other manufactured aggregates. The first stage in most operations is the reduction and sizing by crushing. Some operations, however, provide a step prior to crushing called scalping.
primary crusher--jaw and impact crusher
In stone quarries or in very "boney" gravel pits, large material usually is reduced in size by either a jaw or a gyratory crusher. Both types are compression crushers. Although economical, they have the tendency to create thin, elongated particles. Particle shapes sometimes may be a problem for Producers of hot mix asphalt. In some operations impact crushers are used for primary crushing, but they may have a slightly higher cost per ton. Impact crushers may upgrade poor-quality aggregate and increase separation, such as removal of rebar from concrete in recycling operations.
secondary and fine crusher
Secondary and tertiary crushing, if necessary, are the final steps in reducing the material to a desired product size. Historically, cone and roll crushers were the most common choice crushers, but in recent years impact crushers are more widely used. These crushers also are sometimes used as primary crushers for fine-grained gravel deposits.
The cone crusher (a compression type) simply crushes the aggregate between the oscillating cone and the crusher wall. Clearance settings on this equipment are required to be checked and maintained as part of standard operating procedure.
