Kleemann make an impact

Newcastle-based Holystone Waste Management Ltd have introduced a new Kleemann + Reiner Mobirex MRB 130-ZH primary impact crusher to their fleet.

Kieron Goeghegan, Holystone’s managing director, made the decision to upgrade the current crushing process due to market growth and the current demand for recycled products. The company’s main source of material is from skips, which are brought to one of four transfer stations in the Newcastle district. On-site crushing and contracting are also a major part of the company’s growth.

The decision to purchase a Kleemann machine was based on their experience of owning and operating a Kleemann impact crusher for the last three years. They had previously operated a jaw crusher but found the increased production and product shape from the impactor made the final product more cost-effective and easier to sell. The overall construction and weight of the crusher box has been manufactured to cope with re-bar and debris to the same standard as a conventional jaw crusher and has a built-in safety device for any uncrushable material.


The Mobirex MRB 130 has been designed to allow for maximum production and finished screened product, limiting the need to re-handle oversize. A variable-speed feeder transfers material from the 8m3 hopper on to a large two-deck independent pre-screen (1,200mm x 2,250mm). The top deck is fitted with a grizzly and the bottom deck with a screen mesh, which allows any soils or fines to be screened prior to crushing. This material can either be bypassed or sized and stockpiled by the side conveyor.

The crusher box has a feed opening of 900mm x 1,300mm and is fitted with four rotor ledges. An optional variable-speed rotor allows the operator to control the crusher speed, dependent on materials and production requirements. A fully independent feeder fitted under the crusher box prevents material from damaging and blocking the main conveyor belt and allows free flow of material from the crusher. A 1,550mm x 3,340mm screen box fitted to the main conveyor belt allows material to be screened to produce a finished product and returns any oversize directly back into the crusher or to stock if required.

The screen box can be easily removed for maintenance purposes or if screening is not required for an application. Holystone specifically requested a three-man picking station to be fitted on the return conveyor. The complete mobile crushing, screening and picking station has allowed Holystone to produce quality products at maximum tonnages with one turnkey system. The need for additional screens and picking stations has been eliminated and the overall process is now much more cost-effective.
