Fast-impact fractures lead to uniform particle size

By Chemical Engineering |

This company’s line of horizontal shaft impactor (HSI) crushers (photo) can achieve reduction ratios of up to 30 to 1 in a single stage. Product size is varied by changing rotor speed and clearances. The size reduction takes place along short fracture lines, producing a more cubical product to meet aggregate specifications. This fast-impact fracture is different from the slow-compression breaking in cone or jaw crushers, says the company. Unlike hammer mills, there are no screens or grates holding material inside the crusher, so material is efficiently processed at high rates. HSI crushers are capable of size reduction in all material sizes and hardnesses with minimal maintenance. — Stedman Machine Co., Aurora, Ind.
