It takes 2-3 times of crushing to make sand out of big stones: after the mine blasting, the jaw crusher is used for coarse crushing, and then the cone crusher is used for medium and fine crushing, and finally the sand making machine controls the particles accurately. The blasting plan is tailored, and the equipment selection matches the hardness of the ore. The jaw crusher and cone crusher are used for hard rock, and the impact crusher is selected for soft material. Efficient sand making can achieve millimeter-level particle size control.

In the mining, construction, road and other industries, the crusher is a very important equipment used to crush hard materials into the required particle size and provide necessary materials for subsequent processes. For big stone sand making, how many crushings are generally required to achieve the required particle size?

Generally 2-3 crushings are required

Mine blasting is the first step

For the big stones mined in the mine, the mine blasting is first required to blast the large stones into smaller pieces. Mine blasting needs to consider the nature of the ore, the shape of the ore body, the size of the ore body, the blasting method and other factors. Generally, a professional blasting company is required to operate to ensure safety, efficiency and environmental protection. If it is not a mining mine, then this step is not necessary.

Jaw crusher and gyratory crusher for coarse crushing

After the mine blasting, coarse crushing is still needed to break the stone blocks into smaller stone particles. Generally, jaw crusher, gyratory crusher and other equipment are used for coarse crushing. Jaw crusher is a commonly used crushing machine, mainly used for crushing harder materials. Gyratory crusher is also a commonly used crushing machine with greater production capacity.

Cone crusher or impact crusher for medium and fine crushing

After coarse crushing, medium and fine crushing are still needed to break the smaller stone particles into the required particle size. Generally, cone crusher, impact crusher and other equipment are used. Cone crusher is a commonly used crushing machine, mainly used for crushing medium and high hardness materials. Impact crusher is suitable for crushing materials with lower hardness.

Sand making machine sand

If you need to produce high-quality sand materials, you can use sand making machine sand. Sand making machine is an efficient, energy-saving and environmentally friendly crushing equipment.

In general, for large stones to make sand, it usually takes 2-3 crushings to reach the required particle size. Different materials and different process requirements require different crushing equipment to be selected for crushing.
