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. Die Brechtechnik erzielt einen unvergleichbar hohen Zerkleinerungsgrad. Aus diesem Grund ist der Brecher ideal für die Aufbereitung von Naturstein.
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.
Schrefler relies on RM hybrid crusher
Demolition work and mobile recycling have been part of Manfred Schrefler’s range of services since 2016; previously he was known primarily for transport and earthwork. In terms of machinery, the Upper Austrian relies on top quality and always has the very latest technology.
Basalt preparation
Crushed basalt is used for a variety of purposes. Most often, it is crushed to be used as an aggregate in construction projects.
Increase in orders with cuboid final aggregate
In Mexico the RM 100GO! replaces a jaw and cone crusher combination. Basalt with a diameter of up to 500 mm is crushed into different sizes of cuboid final aggregate, which is then reused for asphalt production. Final aggregate grades between 0-19 and 0 25 mm are processed to a high standard without any problems.
RM 70GO! 2.0 crushes hard river basalt
The first mobile RM crusher in Gorontalo, Indonesia, has been in operation since spring 2017. The new RM 70GO! 2.0 replaces several machines at once: instead of using the jaw crusher combined with a cone crusher, this mobile crusher unit processes extremely hard river basalt in a single pass.
