What is the research and judgment of the crusher industry on the nature of stone?
In daily stone processing, we mainly face limestone, granite, basalt, pebbles, etc., of which limestone is a representative of soft rock, and the size of silicon content can be divided into high calcium stone, fish seed stone, etc., the silicon content of basalt is generally about 40%-60%, the silicon content of granite is generally more than 70, and the silicon content of pebbles is generally more than 85%.
In many years of production practice, Shandong Sanxiang Heavy machinery has gradually explored the degree of wear degree of different stone on machine parts, breaking the misunderstanding that different stone wear on parts is similar in the past. Now that the customer is ready to go on the crushing production line, we first require the customer to bring several stone samples, and then find a professional organization to conduct chemical testing on the stone composition to determine the nature of the stone. Then according to the nature of the stone to recommend what kind of crusher production line customers.
The crushing principle of the production line is generally divided into three categories, and the following is a brief introduction for you:
First, the impact type principle. The so-called impact crushing principle is to use the relevant parts of the crusher directly and the material to be broken in positive contact, hard to hit, this working principle is matched with Jinbaoshan machinery production of hammer crusher and counter plate hammer sand machine, mainly for limestone and other soft rock crushing, investment province, production line supporting simple, large output.
Second, counterattack principle. The so-called counterattack principle is the use of high-speed rotating rotor, the material falls on the counterattack plate or counterattack wall, mainly by falling force, the reaction force of the counterattack plate breaks the material, reduce the wear degree of the material with high silicon content on the wear-resistant parts, this working principle is supported by Shandong Sanxiang Heavy Industry machinery production of impact crusher, cone crusher and other machines.
Third, the principle of extrusion. This crushing principle is mainly used in rough breaking and fine breaking, for the stone crushing with high hardness and large silicon content. Especially the high silicon content of pebbles, the direct impact type principle wear is too large, the impact type principle effect is not very good, both of these crusher rotors are high-speed rotation. The extrusion principle appropriately reduces the crushing speed of the crusher, extrudes the crushing material by the size of the contact surface, and reduces the wear degree of related accessories. This working principle is matched with Shandong Sanxiang Heavy Industry machinery production of jaw crusher, roll machine, roll grinding machine and so on.
Brine point tofu, one thing falls, Shandong Sanxiang Heavy machinery years of production experience tells us that the product selection of different material crushing production lines is definitely not the same, need to be taken seriously.
