Granite, as an important part of the aggregate industry, is widely used in various fields due to its high hardness, strong durability, and good plasticity. The process of crushing granite generally includes two steps: coarse crushing and fine crushing. The following text will introduce it in detail. Granite crushing process

A. Primary crushing--granite jaw crusher

The granite jaw crusher is an indispensable crushing machine for many stones. The granite jaw crusher is also called a stone crusher. Judging from its name, the jaw crusher operates like a crocodile and can "swallow" a variety of high hardness and large-sized materials and crushes them into medium-sized stones by squeezing and crushing for the next step of crushing production.

B. Fine crushing-granite cone crusher

The granite cone crusher is a secondary crushing equipment in the granite crushing production line. It mainly uses the principle of layer-by-layer extrusion to finely crush materials. Generally speaking, as long as the primary crushed stone can reach the appropriate feed size of the cone crusher, the cone crusher can crush it into an ideal finished product, and the unqualified stone will return to the cone crusher again with the belt conveyor for crushing and processing.

Many people probably know that in addition to cone crushers, the impact crusher is also used for fine crushing, but the editor only recommends cone crushers, which are also determined by the hardness and strength of granite .

1. Wear parts

Granite is a material with relatively high hardness, and impact crushing is suitable for materials with low hardness, such as limestone, gypsum, etc. If impact crusher is used to crush granite, its wear-resistant parts will be damaged faster and have to be replaced frequently, and the operation cost is relatively large. So the cone crusher is more wear-resistant, and its crushing the effect is better for granite.

2. Noise

Relatively speaking, the operation noise of cone crusher is relatively small and has little impact on the surrounding environment. However, the noise during the operation of the impact crusher is relatively large. Under the background of the severe environmental protection, low noise interference is also one of the channels for environmental protection.

This combination (jaw crusher + cone crusher) is currently a better solution for the crushing effect of granite. Of course, in addition to these, a hammer crusher can also be used for primary crushing without secondary crushing, or a high-efficiency fine crusher. The effect is good, but everything is advantageous. There must be disadvantages, and we can only adopt a matching plan that has more advantages than disadvantages.
