Robust impact crusher at heart of heavy-duty recycling plant

The Dutch company Van Bentum Recycling has built a fixed rubble recycling plant in the port of Rotterdam, in the Netherlands, which is capable of processing up to 1000 tonnes per hour of C&D materials.

Rubble in sizes of up to 1.5m, including reinforced concrete, can be processed directly, without the need to pre-crush. The single impact crusher can generate product of 80 per cent minus 45mm.

This outcome is achieved, thanks to the HAZEMAG Type AP-PH 2530, one of the largest impact crushers in the world. It is equipped with a HAZEMAG GSK rotor with a diameter of 2.5m and a width of 3m. A 800kW slip-ring motor powers the crusher.

{{image2-a:r-w:300}}Two HAZEMAG apron feeders are used to transport the rubble. The first draws material from the storage bin, and the second, on which the speed can be controlled, separates the mass flow, so that the rubble is evenly distributed across the full width of the feeder. The material is then fed onto an eccentric pre-separator screen which screens out any fine material prior to the crusher.

The crushed material is then conveyed away with two vibrating feeders and a belt conveyor. A magnetic belt separator for the separation of metal components is also installed at this point in the system. The recycling plant was supplied with complete steel construction and electrical switchgear from HAZEMAG.

Due to the quality and robustness of the impact crusher, the wear rate on the internal components is minimal, and maintenance work is only necessary for the replacement of worn wear parts which has cost optimisation as a major feature.

HAZEMAG was one of the world’s pioneers in the recycled aggregates industry, developing crushing and recycling solutions for massive amounts of post-war rubble in 1946. That year, it developed the Andreas impactor, one of the first impact crushers of its kind, to process the massive amounts of demolition materials that had to be cleared in post-war Germany.

From such a humble beginning, HAZEMAG has become a global supplier of crushing and screening solutions for the recycling, cement and aggregates, minerals processing and underground mining sectors.

For the Australian market, the collaboration of the Australian subsidiaries of HAZEMAG and STEINERT has seen combined business know-how, product solutions and services come together under the management of STEINERT Australia.

Via continuous research and development of existing products plus introducing new innovative technology-based solutions and partnerships, STEINERT Australia can provide solutions for Australian industry applications such as the aggregates, quarrying, mining and resource recovery sectors.
