In 2018, Marklund & Son, located in Sweden, already invested in a RUBBLE MASTER impact crusher, the RM 80GO! (now called RM 90GO!). Due to the high level of satisfaction with the crusher and the excellent service provided by their RM dealer OP Systems, the machine park operator made the decision to make another investment in a RUBBLE MASTER machine for the purchase of a much needed scalper plant.

With over 30 employees, Marklund & Son in the north-east of Sweden is one of the largest machinery park operators in Skellefteå. Due to constantly increasing demand, the need to invest in a scalper arose in. Because of the strict environmental regulations of the Swedish government, a screen was needed that is equipped with Ad Blue and has as little impact on nature as possible. An additional, decisive factor was also the excellent relationship with the RM dealer, OP Systems. “Besides the RM 80GO!, which does its job perfectly, the customer service is impressive. We really appreciate the friendly and forthcoming communication,” says Emil Marklund, son of the owner and responsible for concrete crushing and sorting at Marklund & Son.

While the RM crusher mainly crushes concrete, the new RM scalper is now used to recycle valuable materials, such as gravel.

From May to November last year, the RM HS5000M was already able to recycle about 200 tonnes of gravel per hour.

Our crushers in action

RM HS pre-screens

Tracked coarse material screening plants in the RM HS series can process various feed materials such as blasted rock, bulky demolition material and asphalt. All screens in the HS series are extremely robust and high-output. Thanks to their enormous throughput they minimise material handling.

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.
