Recycling building materials with a new compact impact crusher in UK
If anyone from the counties of Hertfordshire, Bedfordshire and Essex wants to recycle building rubble, they’ll usually make their way to Hatfield. The town to the north of London is home to one of the region’s biggest recycling centres.
If anyone from the counties of Hertfordshire, Bedfordshire and Essex wants to recycle building rubble, they’ll usually make their way to Hatfield. The town to the north of London is home to one of the region’s biggest recycling centres.
For the most part, mixed building rubble and asphalt are delivered and processed there. Contractor BP Mitchell Ltd, the operator of the centre, is at the forefront when it comes to the use of cutting-edge technologies. One example is the large washing plant where the recycling material is cleaned and prepared for further processing, which includes a large proportion of the typically English red bricks. Another example is the new state-of-the-art Ciber asphalt plant, which produces high-quality asphalt mixes. The fleet of mobile crushing and screening plants at the centre includes several from Kleemann.
Kleemann plants – intuitive operating
The company’s machine park already includes four MOBICAT jaw crushers, two MOBISCREEN scalpers and a MOBIBELT mobile stacker from Kleemann. “What impresses us time and time again about the Kleemann plants is their innovative features and how easy they are to use. Our people find the handling of the machines amazingly easy. Everything can be adjusted and operated so intuitively and conveniently,” says Brendan Mitchell, CEO of BP Mitchell Ltd.
The new impact crusher achieves grain sizes smaller than 20 mm
The new MOBIREX MR 100i NEO compact crusher easily handles mixed and sticky feed material. The recycling centre in Hatfield produces MOT Type 1 aggregate for road sub-bases. In the UK, this is a blend of crushed and screened aggregates with grain sizes of 40 mm and smaller. The range of particle sizes ensures that the material can be compacted easily to create a solid sub-base with excellent load-bearing properties. At the same time, the recycled material can be used for further processing in the washing plant. The reclaimed asphalt, with grain sizes smaller than 20 mm produced by the new impact crusher, is suitable as RAP feed material for the company’ Ciber asphalt mixing plant.
Adjustment of the crushing gap of the MR 100i NEO at the press of a button
The MR 100i NEO impresses with numerous innovative functions, including automatic crushing gap adjustment, which enables a quick response to changes in the material and can be activated at the press of a button. This enables plant operators to make their processes both faster and more efficient. Switching between various applications is so easy that it’s possible to reconfigure the MR 100i NEO working as a washing plant feeder for the processing of reclaimed asphalt pavement (RAP) with very little effort at all.
High productivity with low fuel consumption
The low fuel consumption of only 11 litres per hour significantly reduces costs. Today, the MR 100i NEO produces material with grain sizes from 0 to 20 mm at a rate of up to 60 tonnes per hour. The large single-deck classifying screen with a screening surface of over 4 m³ also contributes to this high output. The material can spread evenly across the screening surface and ‘bottlenecks’ are virtually eliminated. In the case of larger grain sizes, the output rises to up to 100 tonnes per hour.
The British company can look back on many years of successful collaboration with Kleemann and the UK subsidiary Wirtgen Limited. In addition to the reliability of the plant itself, their advice and services are decisive.
Facts and figures:
- The new compact crusher MOBIREX MR 100i NEO from Kleemann can easily handle mixed and sticky feed material.
- The machine park at the UK recycling centre includes a total of eight Kleemann machines at various locations around the site.
- In the case of the Kleemann MR 100i NEO impact crusher, CEO Brendan Mitchell was particularly impressed by the ability to switch between applications and the low fuel consumption.
