Largest shredder makes strong entry

Construction equipment major Powerscreen has recently launched two high-volume recycling units that promise to significantly enhance productivity.

01 November 2005

Powerscreen International has developed two new recycling machines, both of which are the direct result of customer focussed research and development and specifically designed for large-volume processing of a wide range of waste materials.

“The latest and largest shredder in the company’s range, the Powershredder 2400, is a mobile track-mounted heavy-duty shredder for volume waste reduction tasks,” says a company spokesman. “The new electrically -powered Galaxy 933 Trommel is a multi-task, high capacity screening plant capable of processing up to 200 tonnes per hour and further enhances what is arguably the largest and most versatile range of Trommel screening plants available on the market today.”

Powershredder 2400
The brand new Powershredder 2400 features a number of different tools and shaft configurations for the efficient and high-volume reduction of household, industrial, building and green waste, timber, plastics and logging/sawmill waste. Under measured test conditions, the Powershredder 2400 proved to be able to process up to 105 tonnes per hour of old timber and municipal solid waste and, for bulkier refuse and industrial solid waste, the throughput averaged 55 tonnes per hour, the spokesman says.
He adds: “The Powershredder 2400 produces a consistent and uniform material sizing with a range of tools to match the varied shaft configurations available for optimum materials processing. Operationally, the machine has a low dust and noise emission levels and has a small ‘footprint’ for its high throughput. Also, the crawler undercarriage makes it highly mobile and agile on site.
“In addition, automatic and fixed reverse shafts produce optimum processing of the widest possible range of materials. The shafts, with shredding tools that are welded on, have low wear-and-tear, a long shredding life and low maintenance. A generously proportioned low feed-in tipping hopper (6.35 cu m capacity) allows the shredder to be fed by conveyor, excavator and grab or loading shovel. The hydraulically-folding 1,400 mm wide discharge conveyor, with chevron belting, has a discharge height of 4 m for good stockpiling capacity, loading directly into tippers or direct feed into a secondary separating processor such as a trommel. The conveyor angle is also hydraulically adjustable between 15 degree and 34 degree. The Powershredder 2400 is equipped with remote control for safe distance operation.
Optional extras include hopper extensions and a breaker bar can be installed below the shafts for further size reduction of waste materials, says the spokesman.
The first of the new models, has been delivered to Powerscreen’s long-time customer, City Industrial Waste, where it is working at the company's 22-acre inert landfill, waste transfer and recycling facilities just outside Derry, Northern Ireland. CIW aims to recycle in excess of 90 per cent of the material that passes through the Derry operation.
According to Gerry Farmer of City Industrial Waste: “The Powershredder 2400 is a strong, versatile machine capable of shredding almost all kinds of materials. We can now shred more than twice the amount of waste that we could before. One of the biggest benefits we have found is its mobility. We can track the Powershredder 2400 while in operation and reduce the need to constantly be clearing the stockpiles created.”

The Galaxy 933 Trommel
This high-capacity trommel can process up to 200 tonnes per hour using an electric friction four-wheel drive system with four 15 kW drives. Designed specifically for construction and demolition (C&D waste), reclaiming topsoil, composting applications and wood chippings treatment, the new Galaxy 933 is the largest trommel in the Powerscreen range and is aimed at high-volume recycling operations, says the spokesman.
“The trommel drum on the Galaxy 933 is a generous 2.7 m diameter by 10 m length, giving a screening area of just under 60 sq m. The screen angle can be set at up to 4 degree and the variable speed drum can be set between 13 and 17 rpm. The reversible drive is operated to “rock” the drum in order to clear blockages or material build-up. The drum screen itself is available in one continuous mesh size, or can be split 50/50 or 60/40, depending on customer's requirements. Six independent spring-loaded brushes are standard, with brush cleaners also available.
“Optional extras on the Galaxy 933 include horizontal welded scroll punch plate drum; an inclined drum fitted with individual woven mesh or punch plate panels; stairs and walkway on the trommel frame.
“With low maintenance, integral discharge chute, easy access to trommel drum and a full dust canopy, the new Galaxy 933 is quiet in operation and both user and environmentally friendly,” he concludes.
