    product description

    Stone sand making machine, also known as impact sand making machine, is a domestic level crushing equipment developed based on the actual situation of domestic sand production. The stone sand making machine produced by our company is widely used for the fine crushing and coarse grinding of metal and non-metallic ore, cement, refractory materials, abrasives, glass raw materials, construction aggregates, artificial sand and various metallurgical slags. Special and hard and abrasive materials such as silicon carbide, silicon carbide, sintered bauxite, magnesite, etc., are more superior than other types of crushers. Used with hydraulic protection jaw breaker, it can handle various metallurgical slag. In particular, the sandstone production line and sandstone production line introduced now have a unique effect on sand production, and are suitable for construction sand and road construction sandstone.

    Product advantages

    (1) Simple and reasonable structure and low operating cost. Using the stone-on-stone principle, the wear is small.

    (2) High crushing rate and energy saving.

    (3) With fine crushing and coarse grinding functions.

    (4) It is little affected by the moisture content of the material, and the moisture content can reach about 8%.

    (5) The working noise is less than 75 decibels (db level), and there is less dust pollution.

    (6) Suitable for crushing medium and ultra hard materials.

    (7) The product is cubic, with high bulk density and minimal iron pollution.

    (8) The impeller self-lining has less wear and easy maintenance.

    Simple structure, low cost, stable operation, energy saving, material self-lining in the impeller and vortex crushing cavity greatly reduces the cost of wear parts and maintenance workload, effectively solving the "iron pollution" problem in the process of crushing glass and other raw materials And the "steel stuck" problem in the process of steel slag crushing, the clever internal air flow self-circulation eliminates dust dispersion.

    (1) The structure is novel, unique, simple and reasonable, the operation is balanced, and the operation cost is low.

    (2) "Stone hitting stone" and "stone hitting iron", the state of the device can be changed freely, and sand and crushed stones can be used in one machine. "Stone-to-stone" technology reduces component wear and reduces production costs.

    (3) Low energy consumption, high output, large crushing ratio, energy saving and environmental protection.

    (4) It has the shaping function, the product is cubic, and the bulk density is large.

    (5) During the production process, the stone material can form a protective bottom layer, and the fuselage has no wear and is durable.

    (6) A small number of easy-to-wear parts are made of ultra-hard and wear-resistant materials, which are small in size, light in weight, and easy to replace accessories.

    (7) Air self-circulation system to reduce dust.

    (8) It is little affected by the moisture content of the material, and the moisture content can reach about 8%.

    (9) The main shaft bearings are circulated and lubricated with a thin oil station. There are spare pounds to ensure continuous oil supply to the main engine. Can realize automatic control.

    (10) The top cover is lifted by the hydraulic system, which is easy to operate.

    working principle

    To put it simply, the stone sand making machine uses the "stone hitting stone" principle, which is to make the stones collide with the stones that are thrown out by the impeller during the natural fall process, so as to achieve the purpose of crushing! And the stone that was thrown out by the acceleration collided with the natural falling stone and formed a vortex, and it was broken 2 times during the return process, so the wear of the machine's impact plate during the operation was very little!
