In the mining and construction industries, granite is a common rock with high strength, durability and beauty. However, in order to make better use of granite resources, it needs to be crushed into particles of a certain size. Which crusher is more suitable for crushing granite? How to choose equipment for a granite crushing production line? Here is the answer for you:

 

Granite is an intrusive rock in magmatic rock. The main mineral components are quartz, potassium feldspar and acidic plagioclase, and the secondary minerals are biotite, hornblende, and sometimes a small amount of pyroxene. Among them, the content of quartz is relatively high, up to 50-60%, which leads to high hardness of granite and greater difficulty in crushing. In view of this situation, Dahua recommends high wear-resistant cone crusher!

 

1 Adaptable hardness

 

Granite is a rock with high hardness, and the cone crusher can adapt to the crushing of rocks with high hardness due to its structure and design principle. Its main working principle is to gradually crush the rock blocks into smaller particles through the crushing action of the inner wall of the cone and the crushing wall.

 

2 Controllable particle size

 

The cone crusher can adjust the size of the discharge port to achieve control of the particle size of the crushed product. This is very important for producing sand and gravel aggregates of different specifications and uses, especially in the fields of construction, roads and concrete.

 

3 Excellent particle shape

 

The inner wall of the crushing chamber of the cone crusher is relatively smooth, and the sand and gravel aggregate produced is of good quality, which is conducive to improving the strength of concrete and the compressive resistance of the road surface.

 

4 Wide range of applications

 

Cone crushers can handle many types of rocks, including not only granite, but also limestone, quartzite, basalt, etc. This versatility makes cone crushers very popular in quarries and mines.

 

5 Long service life

 

The special design of the thin oil lubrication system and the precision manufacturing technology used in various wear-resistant parts have greatly extended the service life of the granite cone crusher.

 

Granite crushing  line equipment configuration

Due to its hard texture, the granite production line configuration generally needs to go through 3 stages, namely the coarse crushing of the jaw crusher (first crushing), the medium and fine crushing of the cone crusher (second crushing) and the sand making and shaping of the sand making machine (shaping). Specific crushing process flow:

Large granite materials are fed evenly to the vibrating feeder through the silo, and then enter the jaw crusher for the first crushing. After the coarse crushing, the materials are screened by the vibrating screen as required, and then conveyed by the belt conveyor to the cone crusher for the second medium and fine crushing. After the medium and fine crushing, the circular vibrating screen is used for screening, and the larger particles are returned to the cone crusher for re-crushing. The materials that meet the requirements enter the sand making machine for further crushing and shaping. If the materials need to be cleaned, they can be sent to the sand washing machine for cleaning. Finally, the materials that meet the requirements are classified and packaged according to different particle size ranges.

 

The equipment configuration of the granite crushing production line is mainly determined by the user's stone specifications, output and use of the stone. The process is configured according to the production site. There are different models of crushing equipment, and different models correspond to different production capacities, feed particle sizes and discharge particle sizes. Therefore, the crushing equipment with corresponding production capacity should be selected according to the required stone specifications, output and stone products to obtain the most reasonable and economical production line.
