The RM 90GO! is the second of RUBBLE MASTER’S mobile impact crushers to be bought by a Spanish family-owned company. The built-in wind sifter, which ensures an even better quality of final product, played a crucial role in the decision.
Wind sifter tips the scales
Since late July, an RM 90GO! including a hydraulically pivoting refeeding belt for oversize grain and the RM WS500GO! wind sifter has been crushing C&D waste for a Spanish company. The company invested in an RM80 several years ago, and the family-owned enterprise’s positive experience with this RM crusher played an important role in deciding on their most recent acquisition: Another mobile impact crusher by RM should be purchased! Another reason for buying this model was the additionally integrated wind sifter on the RM MS95GO! mesh deck screen.
The wind sifter blows lightweight materials such as polystyrene and wood into the container, thereby producing an end grain that is purer and of higher quality. This solution allows the customer, a specialist in demolition, recycling and earth-moving, more eco-friendly and more cost-effective operations. The pivoting refeeding belt on the RM RFB7540GO! that can be moved steplessly through a maximum of 180° also helped sway the decision in favour of the RM impact crusher. The 0-32 mm value grain is used as substructure material in road construction.
Our crushers in action
High performance and profitable – these are the characteristics which best describe the RM 90GO!. Packed with versatility it transforms all mineral materials into high-quality cubic aggregate at up to 200 t/h. Thanks to its mobility it is at home in city centres as well as in the mountains.
The mesh deck screen was developed to make our crushers even more efficient. The crushed material is screened to the desired end aggregate size in a single pass. Including precise sorting accuracy.
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.
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.
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.
Crushed basalt is used for a variety of purposes. Most often, it is crushed to be used as an aggregate in construction projects.
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.
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.
