Impact crusher MOBIREX MR 130i PRO

New Kleemann development offers the perfect solution

New arrival: The first MOBIREX MR 130i PRO impact crusher in the world is in operation

In the quarry of Kalkwerke Oetelshofen GmbH & Co. KG in Wuppertal, Hahnenfurth 5, limestone has been extracted for many years as fuel for the blast furnace industry. And since August 2022 with the powerful support of the new Kleemann impact crusher MOBIREX MR 130i PRO, the latest family member of the PRO line. Many years of trust-based co-operation Kleemann played an important role in the decision to invest.

The previous MOBIREX MR 122 Z impact crusher served well for many years in the Oetelshofen quarry. The operating company, AMIRO GmbH, – represented by its managing director Dirk Frorath – would like to use a combination plant in future in which the screening unit is connected directly to the crushing plant: a machine with post screening unit and oversize grain returning.

The new Kleemann impact crusher MOBIREX MR 130i PRO, which has been operating in the quarry since August 2022, provides the perfect solution to this challenge and is now demonstrating its numerous advantages in Oetelshofen: high output, effective screening and excellent product quality. And all of this with a single plant without additional screening plant. Reduced fuel consumption is a further positive feature. Instead of supplying a crushing and a screening plant, now only one machine, which also scores with low consumption values, has to be refuelled.

Efficient double-deck post screening unit

The plant is used today to crush limestone for the furnace industry: Feed size 0/600, final product 0/45. The double-deck post screening unit discharges a final grain size, whereby both screen decks are fully utilised.

A size 50 square mesh is installed in the lower deck for this purpose; a larger mesh is installed in the upper deck as a relief deck. The oversized grain is directed in an uncomplicated process via a reversible transfer conveyor onto the oversize grain conveyor and is then returned to the crushing process.

A new development perfectly suited to the task

To find a solution that meets all the requirements was initially a challenge: "The customer had considered different suppliers and options", explains Christoph Obalski, Sales Wirtgen Germany. "Luckily, with the new MR 130i PRO from Kleemann, we have a completely new machine that is exactly suited to the project. When I told Mr. Frorath about the new product he practically made his decision on the spot", says the Kleemann sales consultant.

"What has always Kleemann impressed me is the Service and spare parts supply."

Mr. Frorath has several machines in operation in quarries and recycling companies Kleemann and is thrilled with the handling, output and efficient mode of operation: "The machine output is excellent and that, of course, is a decisive factor. What has always impressed me at Kleemann is the Service and spare parts supply. It is a healthy, strongly-positioned company with reliable contact partners whose customer support is fast and uncomplicated", says Dirk Frorath.

With its double-deck post screening unit, effective screening and very high product quality is guaranteed with a single plant only – without additional screening plant. Very easy accessibility to all important components thanks to a large number of steps and platforms guaranteed.

Many years of good co-operation tipped the scales

In this case, it was not possible to view the machine in operation in advance, for example, in another company, prior to purchasing. The impact crusher is, after all, a new development. Thanks to co-operation Kleemann lasting many years and good experience with the company's products, however, a very solid foundation of trust existed. And of course the entrepreneur Dirk Frorath was able to view the machine in the Kleemann plant in Göppingen. A visit that reinforced his decision: "The large running gear with heavy-duty framing, easy accessibility via steps and platforms to all components and the solid double-deck post screening unit - this made the first impression perfect", claimed the business operator.

But the inner workings also impressed: The extremely powerful electric motor for driving the crusher with its heavy rotor, the new drive concept and the option of selecting between star-delta drive and frequency converter are beneficial features. Dirk Frorath decided on the star-delta drive. In the limestone quarry, he operates at one speed only but needs the power.

The new MR 130i PRO impact crusher was examined closely on site.

"The large running gear with heavy-duty framing, easy accessibility via steps and platforms to all components and the solid double-deck post screening unit – this made the first impression perfect."

Consistency thanks to the SPECTIVE operating concept

The MOBIREX MR 130i PRO is also equipped with the SPECTIVE operating concept. The operators in the quarry are already familiar with this from the other MR 130 EVO2 plants. "Every now and again we receive very positive feedback from the users", reports sales expert Christoph Obalski, "the machine operators cope with the system without any problems. Once you've got to know SPECTIVE, you can operate all Kleemann crushing plants intuitively."

The components of the latest SPECTIVE generation, such as the new radio remote controls and the digital solution SPECTIVE CONNECT simplify the everyday work routine even more.

Highlights of the mobile impact crusher MOBIREX MR 130i PRO

  • Wide application range: soft to medium-hard natural stone, recycling applications such as the processing of concrete, rubble and asphalt
  • Hourly output of up to 600 t/h
  • Crushing unit with powerful electric 250 kW drive for very high, stable throughput
  • Efficient primary screening guarantees reduced wear
  • Generously dimensioned double-deck post screening unit ensures very high product quality
  • Intuitive operating concept SPECTIVE
  • All-electric drive concept E-DRIVE, option of external power supply – and thus emission-free on site

For Dirk Frorath, the new development of the MOBIREX MR 130i PRO was a stroke of luck and came just at the right moment. After many years of good co-operation with Kleemann, he would only have chosen another manufacturer reluctantly.

Local emission-free operation possible

Thanks to its all-electric drive concept E-DRIVE, there is an option for an external power supply, which means that the machine can be operated locally free of emissions. As the infrastructure in the quarry is not yet designed for such an option, however, the business operator decided on diesel fuel.
