New Edge TRM831 wheeled mounted trommel

Published 11/3, 2022 at 09:49

Edge Innovate has revealed its largest mobile trommel to date with the launch of the new TRM831 at America’s leading compost conference organised by the US Compost Council.

Edge’s latest offering will be one of the largest wheel mounted trommels on the market and has been designed to provide operators with unrivalled production rates. With extensive stockpiling capabilities thanks to its end discharge conveyor design, 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 1,030m³.

The Edge TRM831 portable trommel has been designed for the high capacity screening of various applications including topsoil, compost, sand, household waste and construction and demolition waste. With a wide range of different drum types and screening media available, the TRM831 can be customised to suit the customers exact application requirements.


Design features

The TRM831 incorporates a host of design features such as a remote 180°radial fines conveyor as standard, an eco-power saving functionality which reduces unnecessary running costs, and a user friendly control panel for the easy adjustment of machine parameters. With a screening area of 57m², the TRM831 is fitted with a variable speed 2.3m x 9.3m long screening drum, powered via an efficient hydrostatic drive system. Screening efficiency is ensured thanks to a 9.3m long drum with hydraulically adjustable drum cleaning brushes.

High production rates, said by Edge to be provided by the TRM831, are maintained thanks to Edge’s intelligent load management system which prevents drum overload ensuring that the trommel screen is always operating at optimum performance even with minimal supervision. Enhanced trommel screening results are achieved thanks to a variable drum screening angle. The TRM831 encompasses a 1,500mm wide, variable speed feed conveyor complete with load sensing and automatic feeder shut down to ensure maximised uptime. Additional hopper options include a reject grid and a two deck vibrating screen for the pre-treatment of the feed material. Edge’s HMI control panel with an intuitive operating system allows for sequential start up and the customisation of operating parameters which ensures the TRM831 runs at optimised capacity across all applications.


Operational features

Utilising the latest engine technology, the TRM831 is powered via a 140kW Caterpillar C4.4 Tier 4 Final / STAGE V engine providing extremely low engine and noise emissions. Further fuel savings are said to be made possible thanks to Edge’s unique ‘Eco-Power Saving Mode’ which automatically reduces engine speed to idle when not processing material for a set period. For enhanced savings and zero emissions, the TRM831 is also available with a direct electric power source configuration.

The TRM831 discharges fines material via a radial fines conveyor with a discharge height of up to 6m. With 180° radial functionality as standard, the radial fines conveyor facilitates the creation of stockpiles and is designed to reduce the double handling of material by up to 75%. A wireless remote with an operating distance of up to 100m 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.

The TRM831 has also been designed to provide operational ease and quick maintenance access. Thanks to a large canopy and uplifting drum bin doors, easy access is provided to the power unit and trommel drum for essential maintenance. A quick drum exchange is facilitated via a hydraulic sliding feeder and hydraulic raising drum cleaning brushes. This allows operators to simply lift out the existing drum to be replaced with the various drum types available. Edge’s largest wheel mounted trommel is also fitted with a tri axle bogie complete with fifth wheel hook up and air brakes.  This makes transportation between sites easy with redeployment taking a matter of minutes thanks to hydraulic folding discharge conveyors and chassis jacklegs.
