Precisionscreen sets the scene with the Contractor 604

Precisionscreen leads the way in screening machinery research and development

With decades of expertise in the design and manufacture of mobile screening, washing, crushing and recycling equipment, Precisionscreen stands out from the competition in materials handling and processing.

With its equipment found in more than 15 countries worldwide, the company aids a diverse range of clients in the quarrying, mining and recycling industries.

With Australian-built equipment dedicated to Australia’s specific needs and conditions, Precisionscreen continues to lead the way in research and development, with a commitment to developing innovative products in the traditional washing, screening, crushing and burgeoning recycling market.

One such product is Precisionscreen’s Contractor 604 mobile screen, which is “designed for busy operators with growing sites and a need for equipment that can quickly and easily be repositioned”, Precisionscreen chief operating officer Jonny McMurtry says.

“The Contractor 604 mobile screen can perform diverse screening jobs, including soil, sand and roadbase. The product is quick and easy to set up and move from site to site with its wheeled design.

“With a 6×4 screen and a 1m wide feed belt, the two-deck Contractor 604 can process up to 100 tonnes per hour of material, depending on its density.”

The robust pressed plate main frame provides long-term durability in harsh conditions, with the Contractor 604 including a fully adjustable feed speed and adjustable spring-loaded hopper control gate.

The Contractor 604 is often sold with Precisionscreen’s SM450W 10m wheeled conveyor, which has a variable discharge height of up to 4.5m. With a tow bar and ground pivot, the SM450W has a 650mm-wide belt and hydraulic drive tail drum.

A precoat attachment kit is available for road base. This chute hangs off the conveyor to eliminate the need for nitrile belt on the unit and allows the material to tumble and turn as it passes through.

Before the discharge point on the conveyor, aggregate material triggers a gate on the running belt that sends a signal to the machine to activate the on-board precoat chute and pump.

The precoat nozzles go to work on coating the stone evenly and the accurate coverage ensures maximum efficiency of the precoat material with minimal wastage.

Once material stops travelling on the conveyor belt the gate swings back closed and disengages the precoat pump.

Another option that further expands the Contractor 604’s versatility is Precisionscreen’s rinse kits.

Typically, each deck will have multiple spray bars fitted with numerous spray nozzles. Fine control is available via individual gate valves to each bar.
