Impact Crusher Introduction
     Impact crusher, also known as Impact Sand or efficient Sand, is the introduction of American Barmac company famous "rock stone" crusher principle and technology, combined with the actual situation of domestic sand production, research and development of domestic and international leading level of efficiency crushing equipment. It is widely used in a variety of rock, abrasives, refractories, cement clinker, quartz, iron ore, concrete aggregate and other hard, brittle materials in the debris, crushing (system sand). Construction sand, gravel roads used preferably as appropriate.
Sand works:
    Material from the hopper into the crusher, the sub-feeder the material is divided into two parts, the intermediate sub-feeder into the high-speed rotation of the impeller, the impeller being rapidly accelerated its acceleration up to several hundred times the acceleration of gravity, then at a speed of 60-70 m / sec projectile from three uniform impeller flow channel out, with the first part of the material impact of the sub-feeder four weeks since the resumption of the fall break, and then with the impact on the vortex branch cavity lining materials, top is lining materials rebound oblique impact on the whirl chamber, but also to change its direction of motion, deflected downward movement, rotation Road materials emitted from the leaves form a continuous material curtain. Such a material in the whirl crushing cavity by twice or even several times the probability of impact, friction and grinding crushing effect. The crushed material is discharged from the lower discharge port. And forming a closed loop screening system, three general circulation materials can be broken into 20 mesh or less. Throughout under the crushing process, the material on their own mutual impact crusher, not in direct contact with the metal element, but the impact occurred and lining materials, friction and grinding, which reduces the pollution angle, mechanical wear extended time. Whirl ingenious internal cavity flow from circulation, eliminate the dust pollution.

Efficient Sand Features:

1) This machine is a new development in the nineties, stone crushing equipment, is currently the world's widely used to replace cone crusher, roller machine, ball mill models.
2) structure is novel, unique, smooth operation.
3) energy consumption, high yield, large crushing ratio.
4) devices are small, simple operation, easy installation and maintenance.
5) having a shaping function, the product was cube-shaped, high bulk density.
6) production process, the stone can form a protective bottom to wear and durable.
7) a small amount of wear parts made of special hard wear-resistant material, small size, light weight, ease of replacement parts.
