What is a impact crusher

Impact crusher is one important stone crusher machine in mining industry. When aggregate industry (Cement, Ready-Mix Concrete, Asphalt, Crushed Stone, Sand & Gravel) wants to process rock, sand, and gravel to sale, one such way to process these materials is sending gravel, rock, and sand through an Impact Crusher. It employ sharp blows applied at high speed to free-falling rocks where crushing is by impact rather than compression.

Impact Crushers produce the most uniform cubical shape for finished products. It may be used as primary, secondary, or tertiary crushers depending on the Producer’s final-product-size needs.

Common type of Impact Crushers is Horizontal Shaft Impactor (HSI) Horizontal Shaft Impact crusher consist of a hopper, two or three cavity, a rotor, and hammers (blow bars). Essentially, large products are fed into the hopper where they come into contact with hammers on a spinning rotor which crushes the material into smaller pieces. As the larger material gets impacted by the hammers it comes into contact with each apron rebounding it back to the rotating hammers for another round of impacting until it is discharged out of the impact crusher.

The Hammers are a critical part for impact crusher. What’s the difference compared to hammer crusher? Let talk it next time.
