Conveyor chains, sprockets and sliding guides are all integral components of a sawmill because each piece of timber is carried on chains throughout the sawing process. A sawmill's chains must operate with as little maintenance or interruption as possible.
The process water used in the manufacture of pulp can cause chains to rust.
Chains made from the highest-quality raw materials and processed with the best hardening methods will last the longest.
The lamella chain of a paper mill is a significant investment, and as such, it should be expected to last. Usually lamella chains require little maintenance, which means that their operation has to be extremely reliable.
We have extensive experience working with Finnish machine manufacturers and paper factories, which has helped us to design and manufacture durable chains for handling the roll at different stages of the process.
Heating plants are often operated with very few staff, 24 hours a day, without any site-specific maintenance staff. This is why its conveyor chains must be exceptionally durable and reliable.
The conveyor chain requirements set by the process industry vary tremendously. The array of materials, environments and chain speeds is vast. However, the one thing in common is that the production cannot be interrupted. Once the process is in motion, there can be no unexpected interruptions.
Chains are put to the ultimate test in trucks, where chips and peat are unloaded from behind. During the unloading process the sprockets expose the chain to extreme wear. Wood-based products are usually transported in a corrosive environment, which makes the chains subject to wear and locking. We have developed a specific product to address this problem.
