The H series of direct impact crushers are rock crushing equipments which introduced from American Nordberg Barmac Companys stone hit stone principle and technology. According to the facts of sand making products in china, we lead authorities on effective crushing equipment in china and international by researching and developing. It widely used to grinding and fine grinding of all kind of rock, grinding compound, fire-proof material, cement clinker, quartzite, iron ore, concretes aggregate, etc. And it well accustomed to building sand and road sandstone.

Work Principle: Under the high speed centrifugal force, when the materials vertically fall to the high-speed rotating impeller of machine, the machine can impact and crush the material with other parts of materials which are in umbrella-like formation around the impeller. After impacting with each other, the materials form vortex between impeller and casing and then crush many times which at last be discharged from distributor. The machine

can form the closed circuit and cycle for many times which control the particle size by screening equipment.
