Aggregate crushing plant process

Aggregate crushing is the first step of processing begins after the extraction from quarry or pit. The first stage in most operations is the reduction and sizing by crushing. In the aggregate crushing plant includes scalping,

Scalping in Aggregate crushing plant

Scalping most often is used to divert fines at a jaw primary crusher in order to improve crusher efficiency. In the aggregate scalping process, the very coarse portion is crushed and then recombined with the portion of crusher-run material before further processing.

But If a deleterious or fines problem exists in the finer fraction of crusher-run material (namely, clay, shale, finely weathered material, etc.) the fall-through of the scalping operation may be totally or partially diverted and wasted, or may be made into a product of lesser quality.

Primary crushing in Aggregate crushing plant

In stone quarries or in very “boney” gravel pits, large aggregate material usually is reduced in size by either a jaw or a gyratory crusher. Both types are compression crushers. In some Aggregate crushing plant 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.

After primary crushing/reduction the resulting aggregate generally is placed in a large “surge” pile where the aggregate may be fed into the secondary operation whenever convenient.

Secondary and tertiary crushing

In Aggregate crushing plant, Secondary and tertiary crushing, 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. As with other compression crushers, the cone crusher yields a somewhat elongated and slivery particle shape. One way to choke feed is with a surge hopper and a controlled belt-feed to the cone crusher in the aggregate crushing process.

A roller crusher is another compression type crusher that simply breaks the material by pinching the aggregates. These types of crushers are often found in gravel operations.

Impact crushing in Aggregate crushing plant

Impact crushers may be used as primary, secondary, or tertiary crushers. Despite having a somewhat higher operating cost than other crushers, they tend to produce a more uniform particle shape. Impact crushers usually will benefit the aggregate better than compression crushers, and they may generate more fines.
