Pre Shredder at Lord and Midgley

recycling plant management

Lord and Midgley in Hull decided to install an additional piece of machinery to compliment their recent 3000hp Metal Shreder installation.

The Metso EtaRip® series are used to pre-shred bales and ELVs. This pre-shredding supports optimal shredding operation by feeding it with a uniformly pre-fragmented material. Such approach increases production, reduces wear, keeps electrical power consumption peaks low, and substantially reduces environmental concerns such as noise and explosion risk.

The machinery was ordered in November 2013 and fully installed and commissioned by June 2014.

Already Lord and Midgley has seen a 20% rise in production and a dramatic drop in explosions.

This picture shows Mr Antony Whittaker of lord and Midgley with the installation team.

February 2014 – To prepare for the machine arrival, firstly the civil work had to be carried out. The foundation needed 30 heavy duty piles driven 20 metres into the ground.

The machine that will sit on this foundation weighs in excess of 80 Tonnes and has very heavy loadings. Hence, the necessity of the heavy design criteria.

March 2014 – Here you see the complicated structures of almost 20 tonnes of re-bar steel necessary for the machinery supports. This will now be shuttered in readiness for the concrete pour.

March 2014 – As you can see the shuttering is completed by specialist joiners. Here we are pouring 30 tonnes of high grade concrete.  Due to the physical size of the structure, the concrete and shuttering in left for approximately 5 weeks to allow for drying and proper curing.

Aprill 2014 – Once cured the shutters are removed to expose the finished foundation. The structure is now brushed and cleaned in readiness for the Pre Shredder machine arrival.

May 2014 – Erection commences on the Pre Shredder’s protective housing. The construction utilises heavy duty columns and 15mm thick steel cladding. The building will also incorporate maintenance platforms, Hydraulic power pack and electrical controls.

The building is designed to allow installation from above, this considerably decreases the install time as we pre erected the building before machine arrival. Normally the building is erected later.

June 2014 – The 80 Tonnes of Pre Shredder arrives on site from Germany arriving on two load loader lorries. The machine was installed via the roof of the building. The part shown is the main base body weighing some 16 tonnes and utiising a 250 Tonne capacity crane.

June 2014 – The Pre Shredder main Rotor’s are fixed into place. These have a combined power of over 850 horse power, driven by heavy duty hydraulic motors. The rotors themselves are fabricated from a hardened steel to ensure long wear life.

June 2014 – Installation continues with the fitment of the hydraulics, electrics and armoured protective housing.

July 2014 Pre Shredder complete and in full production, early tests indicate processing Tonnage of high density car bales and car bodies in excess of 100 TPH

Now the machine is on line, the enhancement of the product and production levels exceed expectations. The method of installation and building design will ensure smooth, low maintenance operation for many years to come.
