EDGE’s newest offering will be one of the largest wheel-mounted trommels on the market and is said to offer 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. The model features a remote-operated 180° radial fines conveyor, which can stockpile up to 1030m³.
The EDGE TRM831 portable trommel is ideal for the high-capacity screening of various applications, including topsoil, compost, sand, household waste and construction and demolition waste. The EDGE TRM831 can be customised to suit customers’ exact application requirements with a wide range of drum types and screening media available.
The new EDGE trommel incorporates a host of impressive design features, including an eco-power saving functionality that reduces unnecessary running costs, and a user-friendly HMI control panel for easy adjustment machine parameters.
With an impressive screening area of 57m², the EDGE 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 offered by the TRM831 are 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.
Said to offer the largest hopper capacity in its class, the EDGE TRM831 encompasses a 1500mm-wide, variable-speed-feed conveyor complete with load sensing and automatic feeder shut down to ensure maximum 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 its intuitive operating system allows for sequential start-up and the customisation of operating parameters, ensuring the EDGE TRM831 runs at optimum capacity across all applications.
Utilising the latest engine technology, the EDGE TRM831 is powered via a 140kw Caterpillar C4.4 Tier 4 Final / STAGE V engine, resulting in very low engine and noise emissions. Further fuel savings are 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. The EDGE TRM831 is also available with a direct electric power source configuration for enhanced savings and zero emissions.
The TRM831 discharges fines material via a radial fines conveyor with a discharge height of up to 6m. With a 180° radial functionality as standard, the radial fines conveyor facilitates the creation of impressive stockpiles and reduces 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 EDGE TRM831 is designed to ensure 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 enabled via a hydraulic sliding feeder and hydraulic raising drum cleaning brushes. This allows operators to easily lift out the existing drum to be replaced with the various drum types available.
EDGE’s largest wheel-mounted trommel is fitted with a tri-axle bogie complete with fifth-wheel hook-up and air brakes. Transport between sites is said to be exceptionally easy, with redeployment taking a matter of minutes thanks to hydraulic folding discharge conveyors and chassis jacklegs.
