Quartz gravel, granite and riverbed gravel are not easy to process because high levels of quartz cause high wear. RM mobile crushers are designed for such materials: thanks to their compact size, every RM Compact Crusher can achieve high throughputs even in tight spaces, producing valuable aggregate directly on site at all times.
The crusher can therefore be ideally adapted to the each application. In addition high flexibility, the classic advantages that make RM mobile crushers and screens so profitable in processing highly abrasive rock are the compact dimensions and easy manoeuvrability that make RM machines ideal for working in the smallest spaces.
RM crusher impressive in roadbuilding
The first RM crusher in Nepal – an RM 70GO! 2.0 – has been in action since February 2017. River rock is processed at an average capacity of 120-130 t/hour to make 0/45 aggregate which is reused immediately in roadbuilding.
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!.
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.
River gravel is processed on a regular basis at this gravel pit. An excavator is used to feed in the round material which always has to be screened into three fractions. The TS3600 produces several defined material sizes from round material and separates sand, gravel and grit. Output was up to 200 t/h.
Precision screening of river rock with RM
CP Ptuj in Slovenia has been working with the RM 100GO! together with a mesh deck screen and pivoting refeeding belt since 2016. As the company appreciates the high quality it purchased a tracked mobile post-screen from RM this year. This combination now crushes and screens extremely abrasive river rock from the Drau.
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.
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.
