The customer had specialised in a particular niche: acquiring old bricks for traditional house building projects in his country. As “retro bricks” have a considerably higher value than new bricks, this niche is proving to be more and more lucrative. The only way to acquire these old bricks is to be involved in the demolition of old houses and farms – also castles at times. Waste bricks and concrete are unavoidable in the process, but it would be very expensive to handle their disposal. The customer found a profitable solution in the entry level model RM 60. Weighing in at only 12 tonnes, this impact crusher processes the rubble to make aggregate which, in most cases, is reused on site. The customer has thus found a flexible problem-solver which, with an average capacity of 60 t/h, fulfils all expectations. The company has already invested in the larger RM 70GO! as the recycling quantities have continued to grow.
Our crushers in action
The RM 60 is the most compact RM crusher and the ideal choice for processing smaller quantities for businesses which are looking to expand their activities and increase profits. Like all RM crushers, the 12 tonne model can also be combined with high-performance pre-screens and post-screens.
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.
