New Terex Finlay 883 Spaleck screen helps reduce landfill

Terex Finlay Spaleck 883 screener in action

Finlay Group provide waste processors opportunity to tackle trommel fines issue

THE Finlay Group have reported a surge in interest for Terex Finlay’s new 883 Spaleck - particularly from clients involved in processing construction and demolition (C&D) waste. 

As well as being a high-capacity, low-maintenance machine, the screener - combining Terex Finlay’s heavy-duty 883 with Spaleck’s 3-D combi Flip-Flow design - could help address recent issues resulting from the classification of trommel fines for UK Landfill Tax.

Trommel and screen fines are now classed as non-inert due to the contamination from plastic, wood and other biodegradable waste that is likely to be present. This means that their disposal is charged at a much higher rate of landfill tax than inert waste – representing a significant difference in cost for those involved in the waste processing industry. 

However, the high level of separation that can be achieved with the 883 Spaleck produces a very clean 0-10 mm fine, which - when processing C&D waste - may be mostly composed of particles classed as inert, such as sub-soil and clay, and they might not need to go to landfill at all.

Key to this is the introduction of the Flip-Flow bottom deck on the 883 screener, which uses rubber panels that move in a wave action, as well as expand and contract, to keep the waste constantly in motion.

This readily breaks down sticky material, such as clay and soil, making it possible to produce a 0-10mm fine with minimal contamination from non-inert material such as wood and plastic, which will generally fall into the +10mm particle band.     

Waste enters the top deck, which is composed of four 3-D screening segments formed from open surface panels. As well as preventing waste from becoming caught in the surface and reducing downtime for clearance, this process, which is virtually blockage free, also ensures long, thin pieces cannot pass through to the bottom layer, thereby reducing wear and tear on the lower deck mesh.

Downtime of this machine for maintenance is also kept to a minimum as all the deck panels – 16 on the 3-D top layer and 10 on the Flip-Flow layer – are easily removable, and can be replaced individually or together.  The Flip-Flow panels are screwless and it is possible for all 10 to be replaced by two people in under an hour.

The combination of two machines in one makes the 883 Spaleck economical both in terms of space and the need for additional conveyors.  

Leon Sheehy, managing director of Finlay Plant South East, part of the Finlay Group of companies, said: ‘The 883 Spaleck is really proving its worth out on site. As well as providing waste processors with a possible solution for trommel fines, its sheer processing capacity and ability to tackle significant volumes of materials makes it hard to beat.’
