Chain Conveyors/Maintenance The True Cost of Conveyors

| Author / Editor: Cedric Tchatchouang / Dominik Stephan

Chain conveyors are an essential part of many bulk handling applications — Yet, due to their set–up, maintenance tends to become labor and cost intensive. Now, a new flight assembly design could help to make replacements both easier and faster — Bringing cost reductions while increasing plant efficiency.

Chain Conveyors are used to convey materials such as powders, grains, flakes, pellets and others as an alternative to steel belts or endless belts in continuous processes. Many of these use drop forged chains with flights for material transport. This “en–masse” conveying system is popular due to its combination of simplicity and high efficiency. When it comes to purchasing a chain conveyor, it is easy to look just at the one–time purchasing cost and the quality of the components. But, as conveyors are exposed to a lot of wear and tear, even the best chains can fail after a certain period of time. Yet this can be many years depending on use and maintenance.

If we look at the lifetime cost of such an en–masse chain conveyor, a big part of it is actually maintenance related: The cost of replacement chains and links, labour costs and finally the cost of the downtime. For each and every user, it is vital to have the conveyor running at full capacity as long as the equipment allows it. Maintenance and repair can cost a lot of money and time, usually requiring the services of a team of engineers and considerable resources.
