Scheme 2 is suitable for customers who have high requirements for the size and shape of sand and gravel aggregates.

Taking the equipment configuration in the second scheme as an example, the specific crushing process of granite is as follows:

  1. 1Coarse (primary) crushing: the large stone is uniformly fed into the jaw crusher by the vibrating feeder for coarse crushing.
  2. 2Secondary crushing: the coarse crushed stone is sent to the cone crusher by a belt conveyor for further fine crushing.
  3. 3Screening: the finely crushed stone material is sent to the vibrating screen by the belt conveyor.
  4. 4Sand sand making: the materials which meet the requirement of sand making will be sent into sand making machine for making sand, and others will be returned into cone crusher for re-fine crushing.
  5. 5Finished screening: the materials processed by the sand making machine are sent to the vibrating screen for screening.

The materials that larger than the particles are returned to the sand making machine and continue to be crushed. Small substances are sent to the sand washing machine for cleaning. The cleaned materials are sent to the finished product pile by the conveyor.

Users' feedback:

The entire granite crushing production line requires almost no manual operation except for the start-up, shutdown and routine maintenance of the equipment.

The finished product of the sand and gravel treated by the production line has a uniform particle size, good granular shape and low output rate of stone powder, which can fully meet the demand of strict requirements.

The entire production line has high production efficiency, low operating cost and high profit.

Tips: how to choose (a) suitable granite crusher (crushers)?



1. Wear-resistance

Granite is a material with high hardness and high silicon content, which is difficult to crush in actual crushing operations, or it is relatively high in crushing cost. If an unsuitable crusher is selected, the damage speed of the wear parts will be accelerated, and it will need to be replaced even in a few days, and the running cost will increase.

2. Grain shape

Since granite is a brittle material, the improper crusher will increase the content of the needle-like material and increase the internal crack of the finished product, thereby reducing the application range and increasing the production cost.

3. Production

Two or more crusher types will be used in the granite crushing process, so the combination of crusher is especially important. A good production line will make the crushing process run more smoothly, and save labor power and material resources while increasing production.

4. Dust

The crushing of ore cannot avoid the generation of dust. The diffusion of dust will not only pollute the environment, but may cause downtime if it is slightly inadvertent. Therefore, when the crusher is selected, its sealing system and dust control methods should be perfect.

5. Noise

Under the background of environmental protection, reducing noise interference is also one of the channels for environmental protection. Therefore, when choosing a crusher, noise issues should also be taken into account.
