EDGE TRM831

When California’s leading producer of recycled wood products wanted to increase its efficiency and productivity to meet an ever growing demand for its compost and mulch ranges it turned to its trusted partner Greenrock Equipment, the exclusive distributors for EDGE Innovate products in California, Arizona and Hawaii.

They came up with the perfect solution: the EDGE TRM831 wheeled mounted trommel, the largest mobile mounted trommel screen on the market. Encompassing a 31ft (9.3m) long screening barrel powered by a Cat C4.4 Stage V engine, the TRM831 trommel is capable of screening material at 400 metres per hour,ensuring customers achieve better value for their business.

The Californian producer of recycled wood has been serving landscape contractors, growers, businesses and homeowners throughout Los Angeles, Orange County and the Inland Empire in southern California for more than four decades. Since it first opened its doors in the mid 1980’s, its green recycling operation has grown to cover almost 180 acres.

It manufactures compost and mulch products from landscape trimmings and salvaged wood at one of its six green recycling facilities located throughout the Inland Empire, sourcing and transporting the wood from furniture factories, cabinet shops, lumber yards, landscaping and tree trimming operations using a large fleet of trucks.

Impressive Design Features

Instrumental in helping it to keep up with the demand for its product ranges has been the EDGE Innovate TRM831 with its unrivalled production rates, intelligent load management and extensive stockpiling capacities, incorporating a host of impressive design features such as a remote 180° radial fines conveyor as standard, and an eco-power saving functionality which reduces unnecessary running costs.

"ITS SHEER SCALE PROVIDES OPERATORS WITH UNRIVALLED PRODUCTION RATES, IDEAL FOR OPERATORS SEEKING TO BOOST THEIR PRODUCTION CAPABILITIES"

“The TRM831 is the largest wheel mounted trommel on the market. Its sheer scale provides operators with unrivalled production rates, ideal for operators seeking to boost their production capabilities. High-capacity processing equipment, such as the TRM831 will play an important role in helping Recycled Wood Products meet its production demands,” says GreenRock’s John Connolly.

The EDGE TRM831 portable trommel not only guarantees huge production rates but offers ultra reliability with minimum upkeep, according to John. “Trommel screens from EDGE Innovate are simple to operate and are designed to require minimal maintenance. Customers know they will start up and consistently process large volumes of material day after day without any of the major upkeep you would associate with other products such as star screens.

That’s the biggest selling feature of a machine like this.”

Like all well designed products, the EDGE trommels supplied by GreenRock are smartly designed to make operating them simple. They are loaded with a number of smart features such as an intelligent load management system that ensures the unit is running at optimum capacity at all times whilst minimising the risk of blockages occurring, all the operator needs to do is to keep loading in the feedstock. Full remote functionality over all major functions such a feeder speed and screening angle comes as standard, allowing the loader operator to stay in complete control from a safe distance, whilst a 180 degree remote controlled radial fines conveyor reduces the need to constantly move screened material.

“To further reduce the chances of bridging or drum overload, EDGE Innovate has complemented its intelligent load management system with a larger designed hopper opening and supplied industry leading belt widths to allow a smooth flow of material through the trommel,” John says.

“In the project with Recycled Wood Products, GreenRock’s engineers thoroughly analysed their feedstocks, making precise adjustments to parameters like drum speed, screening angle, feed rate, and the aggressiveness of the drum lifters. They also selected the appropriate screen media to ensure the finished product met stringent quality standards – all before the final handover was completed,” John explains.

Maintenance Made Easy

The EDGE TRM831 is purpose-built to maximise operator convenience, simplify maintenance, and boost overall uptime. Key features such as a large canopy and upward-opening drum bin doors offer unobstructed access to the power unit and trommel drum, significantly streamlining routine servicing. Additionally, the hydraulic sliding feeder and hydraulically raising drum cleaning brushes enable quick and effortless drum changes, minimising downtime and keeping production moving.

Equally important is having properly trained staff. Operators who understand how to safely and efficiently run and maintain the machine contribute significantly to both productivity and workplace safety. GreenRock Equipment recognises this, which is why, during the installation of the EDGE TRM831, they worked closely with the Recycled Wood Products service team and plant operators throughout the commissioning process. This collaboration ensured that the entire team received thorough training, empowering them to operate the TRM831 confidently and effectively from day one.
