“There aren’t many crushers that are capable of processing asphalt as well as other recycled materials. That’s where RM crushers stand out from the crowd. RM crushers and screens are robust and get the job done,” says Matthew Crofts, Director of Chapman’s in the UK. The company crushes and screens mainly asphalt, but also other materials. That is why they were looking for crushers and screens that perform well when processing asphalt as well as being able to handle C&D waste and different types of natural stone reliably too.


Special geometry and easy handling

“The special geometry of the RM impact arm and the fact that you can adjust the impact arm ideally in just a few steps ensure that the asphalt stays in the crushing box for longer. This ensures that smaller and perfectly cuboid value aggregate is produced in a single pass. This means less oversize aggregate, which in turn means less refeeding to achieve the desired grain size. That is now RM crushers save a great deal of time and costs when crushing asphalt. In a nutshell, RM crushers are ideal for crushing asphalt,” explains Paul Donelly, Managing Director of RM sales partner Red Knight 6. Another reason for the excellent asphalt processing is the unique design of the full-length feed channel, which protects the motor compartment below from contamination. In addition to protecting the motor from sticky asphalt dust, it also provides advantages for other applications.



Unique wide mesh radiators ideal for asphalt crushing

An additional challenge when crushing asphalt is the extremely sticky asphalt dust. The dust adheres to the hot radiators on the machine and reduces efficiency. RUBBLE MASTER has implemented an effective solution for this as standard: wide-mesh radiators. These keep the air circulating, the radiators don’t run as hot, so less asphalt dust adheres to them. The result is that machine operators save hours of cleaning work with aggressive chemicals.


RM crushers and screens are efficient both alone and in a team

“Due to the high throughput of the crushers, we also needed screening equipment with greater efficiency and capacity,” says Crofts, explaining Chapman’s requirement for five pre-screens and five post-screens. “When we tested the screens, we saw how well the crushers and screens worked together as a processing line, as well as on their own. The RM crushers and RM screens are simply better than anything I have seen during my many years in the business. It is the screens in particular that have helped us take our company to the next level. Our fleet of RM crushers and screens now gives us precisely this potential to produce a wide variety of materials into high-quality final aggregate. Add to that the fact that Red Knight 6 support us with the highest level of service and after-sales, and I can only say that for me, this is the complete package!” adds Crofts.

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.
