Secondary Impact Crusher Production
The feed enters the primary crushing chamber and meets the breaker bars which impel the feed against the front breaker plate. This action and the collision of material against new feed results in impact reduction. Material is sufficiently reduced in the primary chamber and passed by the front breaker plate, entering the secondary chamber for final reduction. Breaker plates are shaft suspended at the front and from a spindle in the rear, allowing for continuous gap adjustment as wear progresses and assuring superior product control.
This stone crushing machine has a multi-turn breaker bar for extended life before change out and provides years of dependable service. The features of the Grand-Slam deliver unmatched throughput of any competitive machine on the market, making the Grand-Slam HSI highly economical.
