Automated sawmills require reliable machinery to continue operating in difficult conditions, even when lubrication systems seem to be at odds with the constant accumulation of sawdust and woodchips. However, one of the major European sawmill businesses found a solution in the form of Tsubaki's Lambda chain that has significantly cut maintenance costs and improved productivity.
The operating conditions in any sawmill are tough for moving machinery due to the large amounts of airborne dust from the cutting and shaping processes. Most sawmills employ a variety of conveyor systems to transfer timber between each processing station and these rely on chains to do most of the heavy lifting.
The efficiency and reliability of a chain driven system highly depends on the interaction between the chain and sprocket. Just the smallest discrepancy in size can lead to stress damage to the chain, while low quality materials can cause the sprocket to wear and require early replacement. The Tsubaki range of sprockets has been manufactured from high quality steels to integrate seamlessly with all standard chain sizes and ensure a long and reliable service life.
Tsubaki UK has supplied BSW Timber, the UK's largest specialist sawmill business, with a complete solution to their conveyor system maintenance problems. Shaping the wood from rough-cut logs requires a five stage conveying process, involving loads of up to 10 tonnes of timber and exposure to considerable amounts of airborne debris. From the initial Drive Ramp Conveyor to final Chipper Edging Machines, the non-lube low-elongation properties of Tsubaki's Third generation Lambda chain has significantly cut maintenance costs and downtime.
