The new chain operates with a conventional 3¼ inch chain and gets improved tensile strength from larger links and greater pin diameters than previous chains.
Joy’s field trials showed a reduction of three decibels in the noise exposure level to a typically located continuous miner operator.
The conveyor chain is driven on both sides of the conveyor by two parallel eight-tooth sprockets and drives each chain link as it passes around the sprocket.
Joy said the increase in contact between the chain and the sprocket led to a decrease in wear and tear on both components, increasing their working life.
The dual-sprocket conveyor chain is available for 30in and 38in (762mm and 965mm) wide conveyors.
