Northern Ireland-based EDGE says the new offering will be one of the largest wheel mounted trommels on the market and provide operators with unrivalled production rates.

It says the TRM831 has extensive stockpiling capabilities thanks to its end discharge conveyor design, which 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 (1347yrd ³).

Other features of the TRM831 include a remote 180°radial fines conveyor as standard, an eco-power saving functionality which reduces unnecessary running costs and a user-friendly HMI control panel for the easy adjustment of machine parameters.

The TRM831 has a screening area of 57m² (613.5yds²), and is fitted with a variable speed 2.3m X 9.3m (8’X31’) long screening drum, powered via an efficient hydrostatic drive system.

EDGE says screening efficiency is ensured through a 9.3m (31ft) long drum with hydraulically adjustable drum cleaning brushes. High production rates are maintained due to EDGE’s intelligent load management system which prevents drum overload and ensures that the trommel screen always operates at optimum performance with minimal supervision. Enhanced trommel screening results are achieved thanks to a variable drum screening angle.

The TRM831 is claimed to offer the largest hopper capacity in its class, and encompasses a 1500mm (60”) 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 features an intuitive operating system that allows for sequential start up and the customisation of operating parameters to ensure the TRM831 runs at optimum capacity across all applications.

The trommel is powered via a 188HP (140kw) Caterpillar C4.4 Tier 4 Final/STAGE V engine, resulting in extremely low engine and noise emissions. EDGE says further fuel savings are made possible thanks to its 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 EDGE TRM831 is also available with a direct electric power source configuration.
