Improve your Size Reduction
Expect More from your Horizontal Shaft Impactor Horizontal Shaft Impactors (HSI) were first implemented in the midst of the last century. Since then they have taken over the size reduction process in many industries. Here's why, and how. ERIC MARCOTTE
the mineral processing industry usu- ally evolves rather than revolution izes, but the Horizontal Shaft Im- d pactor (HSI) has revolutionized the crush-- ing process in numerous industries. There are several varieties of HSI, and their simi larities are more numerous than their dif ferences. All varieties feature externally fed horizontal rotors with breaker bars, which propel material into a series of apron-mounted breaker plates that crush or pulverize many different types of mate- rials to specified degrees of fineness.
