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.
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!.
