Following a two-month test phase, Holcim decided to purchase the RM V550GO! together with the RM CS4800 for their gravel pit in Brunnen. They later exchanged the RM CS4800 for a larger RM MSC8500M-3D re-screen. Only recently, another RM V550GO! and an RM HS5000M joined the fleet as rental machines. Daniel Gisler, workshop manager at the gravel pit, is pleased with the choice of machine, “The RM V550GO! is unique and is exactly the machine we need for our application. The final aggregate is cuboid and of very high quality. We are highly satisfied!”
The tracked vertical shaft impactor combines the advantages of cone and impact crushers, making it the ideal machine for processing larger and hard material in the natural stone sector. The quality of the crushed limestone is particularly important to the Brunnen gravel pit, as an exact final aggregate size and a cuboid shape are required for the production of concrete gravel. Daniel Gisler is also enthusiastic about the versatile RM screens “The screening curve is excellent! We achieve great screening quality while maintaining high throughputs.”
Some years previously, the Swiss company had already been interested in the RUBBLE MASTER brand: “We spent a long time looking for a suitable crusher. When we discovered RUBBLE MASTER, we were impressed. I took the time to go to a demonstration to see the machines in action. I’m all the more pleased that we’re now working with several RM crushers and screens!”
Our crushers in action
RM V550GO!
Der RM V550GO! vereint die Technik eines Kegel- und eines Rotorschleuderbrechers. Kombiniert mit den Vorteilen des RM GO! Prinzips ist er eher ein vollmobiles und kompaktes Sand- und Splittwerk, als ein mobiler Brecher. Die Brechtechnik erzielt einen unvergleichbar hohen Zerkleinerungsgrad.
RM MSC Nachsiebanlagen
In nur einem Arbeitsgang bis zu fünf Fraktionen produzieren – das schaffen die raupenmobilen Nachsieben der RM MSC-Serie und geben Ihnen den notwendigen Vorteil am Markt. Je nach Bedarf können Sie eine 2-Deck oder 3-Deck Maschine im Steinbruch, für Kies und Sand oder Bauschutt einsetzen.
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!.
