Jarno Mäentausta – the owner of T:mi Jarno Mäentausta – has been offering excavation, quarry and construction work mainly in the south and south west of Finland for many years. He also provides transport services and is a supplier of gravel and grit. Since the beginning of 2019 when he purchased a mobile crusher unit from RUBBLE MASTER, the Finnish business has also been active in processing and recycling reinforced concrete and asphalt. “Our objective was always to offer flexible solutions for our customers. Investing in the RM 120GO! enabled us to enter the new recycling market and offer these services to our customers as well,” says company owner Jarno Mäentausta.

Right from the start Jarno Mäentausta put his new RM 120GO! to the test in Säkylä, successfully crushing concrete and asphalt on site. That was followed by deployment to different different job sites until the crusher unit was relocated in Summer 2019 to the NCC asphalt plant in Nokia, where it produces asphalt with a grain size of 0-16 mm. The high-performance RUBBLE MASTER crusher has been in trouble-free operation there for more than 700 operating hours. Producing a final aggregate of 0 – 16 mm and working 10 hours a day, throughput capacity is around 200 tonnes of asphalt per hour. This is an impressive performance, especially considering that the tare weight of the compact crusher unit is just 35 tonnes (42 tonnes with the RM MS125GO! screen fitted).

Jari Mäntylä – the machine operator at T:mi Jarno Mäentausta – is also impressed by the efficient feeding process as well as how easy it is to operate the machine using the remote control that enables him to move the crusher even while it is processing material. This offers a major advantage because no downtime is needed to change the location of the machine. The magnetic separator, which is positioned on the main discharge belt of the RM 120GO!, also impresses the Finns. This automatically and reliably removes metallic items from the material to increase final aggregate quality.

Jarmo Syrjälä, Sales Manager at RM sales partner in Hansa-Machines, sums up the advantages of the RUBBLE MASTER crusher: “The cost-effective crusher from RUBBLE MASTER offers an excellent performance to weight ratio. The compact design of the machines also allows quick and easy deployment to different job sites. The crushers are easy to operate and maintain, the final aggregate is consistently high quality and the final aggregate size is easy to control.”

Our crushers in action

RM 120GO!

The new RM flagship with an output of up to 350 t/h catapults RUBBLE MASTER into a new league. Thanks to the easy exchange of the impact plates the mobile crusher can be used flexibly in both the natural stone and recycling industry.


Even in the heat of summer, an RM mobile crusher effortlessly processes waste asphalt into cubic final grain. Because huge quantities of waste asphalt are produced every day, companies can discover a lucrative new business in recycling asphalt. Here you will find examples of users who more than p

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.

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.

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.

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.

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!.
