In stone crushing plant design, we should consider many factors. The hardness of the stone is always the first factor we should to consider. Granite, basalt, dolerite, river stone belongs to hard stone with high silicon content. When customer want to crush these hard stone, it is better to use the hard stone crusher, if choose the soft stone crusher, the crusher wear will accelerate, maintenance interval will increase, so the cost will increase. For hard stone crusher, we recommend to you the Kefid jaw crusher, CS cone crusher, HPC cone crusher.

In the actual crushing line, we must take full account of the investment cost and practicality in order to obtain the greatest return on investment. Therefore, the design of hard stone crushing line, we recommend Vibrating feeder, jaw crusher as primary crushing, cone crusher as secondary crushing, and vibrating screens accompanied by other equipment such as belt conveyors, electric control panel and dust collector.

The role of each machine in the whole production line:

Vibrating feeder: It used to transfer a mass flow of stone from hopper to primary jaw crusher evenly, periodically and continuously.

Jaw Crusher: Jaw Crusher is ideally suitable as primary or secondary crushing which can meet most crushing requirement. Adjustable discharging opening of jaw crusher can allow perfect match with relative equipments in the next stage.

Cone Crusher: Cone Crusher can be widely used in medium crushing, fine crushing and super fine crushing field. After first crushing, the material will be fed into cone crusher by belt conveyor for secondary crushing.

Vibrating Screen: Screen can separate aggregates to different size. It is the most general means of size control in aggregates processing. The crushed stone by cone will be transported to vibrating screen for separating, and the other unqualified aggregates will be returned to cone crusher.

In the hard stone crushing plant, the whole crushing process forms a closed circuit for aggregates. Final products size can be achieved according to client’s requirement. If customer need more information about the hard stone crushing plant design, contact online service for technical support.
