The first live US demonstration of Rockster’s new impact crusher R1000S took place at a recent demonstration day by Equip Sales and Leasing in Connecticut state.
The R1000S was one of eight different machines from Austrian manufacturer Kormann Rockster Recycler that were on show during the Live Crushing Demo Day at a quarry of Equip Saels’s sister company Modern Materials.
Equip Sales has sold many Rockster units into the US and Bermuda, off the south-east coast, since they started working together in 2009, said Joe Collazo, sales manager at Equip.
Wolfgang Kormann, chief executive of Rockster Recycler, said the R1000S is a crusher that combines state-of-the-art technology with long-proven Rockster standards including the hydraulic system. “We are sure that this was the right step.”
The R1000S is a self-monitoring unit designed to increase operating and safety comfort. Refinements include an easy gap adjustment for a simpler grain size adaptation, and an integrated measuring system for full machine control and analysis. There is also a two-deck pre-screener for a further grain fraction plus increase of the machine efficiency.
An inlet opening of 1016mm x nearly 737mm allows infeed of large material and offers a high output capacity for varying sized material at rates of about 272tonnes/hour.
Basic features on the R1000S include an adjustable bypass chute, vibration feeder with two-deck pre-screen, vertically adjustable magnetic separator, remote control with colour display, electronic controller with colour display, soundproofing, a dust suppression system and crusher overload protection. For the event, the optional RS100 screen box and the RB92 double-function return/stockpile belt was fitted. The complete system weighs 35tonnes, is 14m long, 2.8m wide and 3.5m high.
Other Rockster products at the demonstration event included the impactors R700S and R1100DS, the finishing screen RDS410, scalping screens RSS410 and RSS514, and two stackers - RST18 and RST23.
By using a Rockster crusher in combination with a stacker, clients can increase their productivity through much larger stacking capacity, said Kormann. All impactors at the demonstration were equipped with Rockster’s closed-circuit system with the removable screen box and the double functional return/stockpile conveyor. These accessories allow producers to crush material in one pass and yet gain a consistent high-quality grain without further crushing or screening.
