Houses, hotels, municipal buildings, sewage treatment plants and agricultural units, roads, bridges, ski lifts and avalanche barriers – Loretz SA in the Swiss canton of Graubünden offer a diverse and demanding range of civil engineering projects. For the team working for the two managing directors Dario Loretz and Guido Friberg, the idea of processing job site material themselves was obvious. Around seventeen years ago, following a thorough study of feasible suppliers, the decision was made to purchase a crusher from RUBBLE MASTER.

The RM80 kicked off RM’s career at Loretz SA. Having soon proved its worth, the purchase of an RM 100GO! followed around 10 years later. Our crushers’ “career” continued with the high-performance compact RM 120GO! crusher that they are currently using. It processes asphalt, concrete, medium-hard natural stone and general C&D waste into high-quality end products. Managing Director Dario Loretz talks about his company moving from the especially compact RM80 to the RM 120GO!, which is currently top of the crusher range: “The machines are extremely easy to handle and incredibly versatile – asphalt, C&D waste, natural stone – we crush everything that can be crushed. Working together with Peter Schärer from RUBBLE MASTER SCHWEIZ AG is also great! Spare parts are available remarkably quickly, even if they are supplied from Austria.”

The flagship RM 120GO! crusher has a throughput capacity of up to 350 t/h and meets the highest specifications in terms of performance, ease of maintenance, efficiency and design. Weighing just 35 tonnes, the RM 120GO! is the most compact crusher in its class. Its drive concept allows location-independent, environmentally friendly, low-noise and low-emission operation. “We recycle the continually increasing quantities of C&D waste into valuable building materials and ultimately make an important contribution to environmental protection,” says Guido Friberg.

RM 90GO!

Leistungsstark und rentabel – diese Eigenschaften beschreiben den RM 90GO! am besten. Vielseitig wie er ist, verwandelt er jedes mineralische Material zu hochwertigem kubischen Endkorn, bis zu 200 t/h. Dank seiner Mobilität ist er sowohl in der Innenstadt als auch im Bergland im Einsatz.

RM 100GO!

Der RM 100GO! ist der Star der mobilen Brecher – ein mobiles Power-Paket für jede Anwendung. Innerhalb weniger Minuten ist er voll einsatzbereit und verarbeitet rasch die unterschiedlichsten Materialien. Mit einem Eigengewicht von nur 29 t bricht bis zu 250 t Material pro Stunde.

RM 120GO!

Mit einer Durchsatzleistung von bis zu 350 t/h katapultiert der RM 120GO! RUBBLE MASTER in eine neue Liga. Durch einfachen Austausch der Prallschwingen, ist der mobile Brecher sowohl in der Naturstein- als auch in der Recyclingindustrie flexibel einsetzbar.

Natural rock

Crushing at a high output and low wear, and that in every possible and impossible location, is not an issue for RM crushers. They manage to generate the highest quality value grain from natural stone on site. Depending on the desired combination of machinery. The end result is always cubic aggregate.

Abrasive rock

Quartz gravel, granite and riverbed gravel are not easy to process because high levels of quartz cause high wear. However, RM crushers are designed for such materials: thanks to their compact size they can achieve high throughputs even in tight spaces, producing valuable aggregate directly on site at all times.

Crushing gravel with 90% quartz content

Processing 24,000 tons of gravel with a quartz content of around 90 percent to produce 0-32 mm value grain
– that was the right challenge for the RM 100GO!. The mobile power pack with its wear-resistant hammers rose to this challenge in the Vienna basin extremely economically. Excavator and loader drivers are impressed.

Endurance in riverbed gravel

Building roads to connect to eastern Mexico was difficult because of the problematic terrain. It was necessary to prepare materials on site because of the remote locations of the construction sites. The RM 70GO! is ideal for challenges like this. Its manoeuvrability make it a perfect machine.

High demand for crushed sand and grit

The Swiss company Mühlebach AG has been successfully processing gravel for 40 years. As pioneers in this business field, they demand machines that are state of the art. They have now added an RM V550GO! to their fleet of machines in order to meet the demand for crushed sand and grit.

Impressive RM V550GO! performance in Argentina

At the beginning of the year the RM V550GO! made light work of transforming 0-200 mm river rock into fine 0-19 mm value grain. The awesome capacity and low diesel consumption were key in the Argentine company’s decision to purchase the RM V550GO!.
