Rockster R1100 Crushes up to 350 Tons Per Hour

The Rockster R1100 impact crusher is 32 tons (29 t) total weight and crushes up to 350 tons (317.5 t) per hour. With this machine Rockster has entered a new performance-dimension within the compact crushing class.

“Our existing series of mobile crushers, with the 25-tons plant R900 as biggest machine has already proved itself and consolidated its position on the international market,” said Rockster CEO Wolfgang Kormann. “However, additionally we got more and more requests from our distribution partners concerning a bigger machine, covering a wider market segment. The target: a crusher that still features compact transport dimensions, but at the same time boasts a performance level of more than 300 tons per hour, adequate for covering major transactions.”

The result is a machine which fits into the existing product line and features a variety of technical highlights: as well as the R900 and R800, the R1100 is equipped with a fully hydraulically drive system. Furthermore, the R1100 features a 2-step and 6 ft. (1.8 m) long pre-screener. This ensures not only a maximum pre-screening quality, but also a further increase of the throughput rate, a reduction of the wear costs as well as a perfect separation of final material and earthy substance, according to the manufacturer.

Two In One: Rockster Duplex Exhange System

The two bigger models R900/R1100 (impact crusher) and R800/R1200 (jaw crusher) are constructed in a completely identical design, in order to realize the creation of a crusher exchange system — the Rockster duplex system.

Both crushing units are interchangeable and can be installed on the same machine through the identical drive system. Within only fours hours the impact crusher can be transformed into a jaw crusher — and vice versa.

Produce Defined Final Grain In Only One Step

With the available optional products, the Rockster crushers can be transformed into a crushing and screening combination producing a 100 percent defined final product with just one machine. Adding the 1-deck screening box RS83/94 and the return belt RB75/85 for bringing back the oversize material into the crushing process, is very easy and can be done in shortest time, according to the manufacturer.

These options don’t require any separate drive system as they are driven by the additional hydraulic unit of the crushing plants. The whole combination can be left on the crusher for transport.
