A waste management business founded in 2005 and based in the North West of England has become one of the latest companies to invest in an new EDGE TRM31 trommel. SED Services Ltd has grown to become one of the leading companies in the waste processing sector, offering waste producers cost effective and environmentally friendly recycling solutions for non-hazardous wastes and helping to reduce greenhouse gas emissions. Earlier this year it expanded its operations with the acquisition of a state-of-the-art composting site at Kirkby, bringing to four the number of sites it now operates in the Merseyside region, the others located in Wigan, Formby and Hightown, employing a total of 180 staff.

The 10-hectare Kirkby facility is now supporting SED Services to deliver contracts secured with the Greater Manchester Waste Authority and five of the six Merseyside Authorities. The site will save some 280,000 tonnes of waste from entering landfill and has also created new jobs across the business, including plant and weighbridge operators, as well as account staff and transport personnel.

Its rapid expansion in recent times has been fuelled by growing demand for its products, not least its top quality 10mm sustainable peat free PASS100 compost, and its recent partnership with Evergreen Garden Care, the firm behind the Miracle-Gro brand in the UK. To meet that demand it has invested in what is the largest trommel of its kind, a 37 tonne TRM831 from EDGE Innovate.

THE LARGEST MOBILE TROMMEL SCREEN ON THE MARKET

Launched at America’s leading compost conference organised by the US Compost Council, it is also one of the biggest wheel mounted trommels on the market. It is fitted with a tri-axle bogie complete with fifth wheel hook-up and air brakes. Transportation between sites is exceptionally easy with redeployment taking a matter of minutes thanks to hydraulic folding discharge conveyors and chassis jacklegs.

SUPERIOR COMPOST SCREENING 

With extensive stockpiling capabilities thanks to its end discharge conveyor design, screening material at 400 metres per hour, the TRM831 design prevents product cross-contamination and reduces the double handling of material. This is complimented by a remote operated, 180° radial fines conveyor which has the capacity to stockpile up to 1030m³ (1347yrd³).

By all accounts, it has been a game-changing investment for SED Services. Comments Managing Director Stuart Baldwin: “Since going into partnership with Evergreen, who operates a substantial bagging plant, demand for our products has increased significantly, so we needed a machine that could handle bigger tonnages at a higher rate. We are very good at making the products, while Evergreen excel at marketing the product, so it made sense to join forces.” 

DOING THE WORK OF TWO TROMMELS SCREENS

“The EDGE TRM831 does the work of two six metre trommels, with a bigger screening surface giving us the option to process more tonnage per hour…”

“The 10 metre EDGE TRM831 does the work of two six metre trommels. The screening drum is taller and has a bigger screening surface giving us the option to process more tonnage per hour. It is so much more cost effective; rather than running two trommels, we are now running just the one.”

Its high production rate is maintained thanks to EDGE’s intelligent load management system which prevents drum overload and ensures that the trommel screen is always operating at optimum performance with minimal supervision. Enhanced trommel screening results are achieved thanks to a variable drum screening angle. Stuart says he also likes the fact it is mounted on wheels. “A static unit which is usually tailor-made for a customer would invariably be scrapped once it outgrows its use, so the fact this new trommel is on wheels gives us the option to move it from one site to another – and it always has a second-hand value, meaning you have something to trade in if you want to upgrade.

“We are also impressed by the machine as it is extremely user friendly, easy to operate, and very accessible; everything you need to get to is at hand when you open up the guards making servicing and maintenance so easy.”

A large canopy and uplifting drum bin doors give easy access to the power unit and trommel drum. A quick drum exchange is facilitated via a hydraulic sliding feeder and hydraulic raising drum cleaning brushes. This allows the operator to simply lift out the existing drum to be replaced with the various drum types available.

Powered by a 188hp (140kw) Caterpillar C4.4 Tier 4 Final / STAGE V engine, resulting in extremely low engine and noise emissions, the EDGE TRM831 incorporates a host of other impressive design features such as an eco-power saving functionality which reduces unnecessary running costs and a user-friendly HMI control panel for the easy adjustment of machine parameters.

With an impressive screening area of 57m² (613.5yds²), it is fitted with a variable speed 2.3m x 9.3m (8’x31’) long screening drum, powered via an efficient hydrostatic drive system. Screening efficiency is ensured thanks to a 9.3m (31ft) long drum with hydraulically adjustable drum cleaning brushes. The wireless remote with an operating distance of up to 100m (328’) gives the operator control over engine and feeder speed, screening angle, tipping grid cycles and full control of the radial fines conveyor including radial functionality and discharge height adjustment.

QUICKEST RETURN ON INVESTMENT

Before making the investment in the TRM831 trommel, Stuart met up with the team at EDGE Innovate and says he has been impressed by the manufacturer’s high level of service and support, and he adds: “Acquiring the TRM831 trommel has already brought us many benefits. With demand for our peat free product only going to grow, it will quickly pay for itself. If EDGE Innovate made an even bigger machine, we would have it!”
