Dual Conveyor Sprocket

Dual Conveyor SprocketAll Joy continuous miners are equipped with the patented JOY dual-sprocket continuous miner conveyor chain. The dual-sprocket chain is 50% stronger in tension than conventional chains and is driven by two parallel 8-tooth sprockets which provide better torsional rigidity. Combined, these features reduce the probability of abrupt chain breakage. Increased contact area between the chain and sprocket significantly decreases the amount of wear, increasing the working life of both components. The dual-sprocket conveyor chain has an even pitch and travels smoothly around the sprocket and return-roller, reducing the noise generated by up to 3 decibels and consequently reducing the noise exposure level of the typically located continuous miner operator.
