Impact Crushers – VSIs and HSIs. Impact-style crushers include VSIs, as well as horizontal shaft impactors (HSIs), and are best used with less abrasive rock types, like limestone. These types of machines break apart material by the impacting forces of certain wear parts known as blow bars and impact plates or toggles.. Some operations also use impact-style crushers after they have already

Starting at the quarry, we provide bottom line bits, slips and wedges, bull wedges and slips. Once the stone enters the mill in block form, we machine gang-feed screws and nuts that control the cutting process. We service gang carts and saw beds, as well as many other unique parts, even those that have become scarce over time.
