17/03/2016: Revolutionary solution to minimise conveyor maintenance costs
How “Bolt ‘n’ Go” Chains keep the running costs down

First published in Milling and Grain, January 2016

Chain Conveyors are an essential part of many bulk-handling systems. Many of these conveyors use drop forged chains with flights as a means of conveying the material being handled. This ‘en-masse’ conveying system is very popular as it is a simple but highly efficient system of moving material. When it comes to purchasing a chain conveyor, it is very easy to just look at the one-time purchasing cost and the quality of the components.

However, the problem with conveyors is that they are exposed to a lot of wear and tear, and even the best chains can fail after a certain period of time. Traditionally, the flights are made of steel and welded onto the links. The links with flights are then assembled in many different arrangements using pins and circlips, headed pins and circlips or headed pins with collars and roll pins. The whole assembly is very robust and works well until general wear and tear, operational errors or material build-up can require maintenance shut down.

In the case of a minor incident, such as the flights breaking, although the chain does not require changing, it is still necessary to order new chain links with flights welded or grind the sides of the failing links and weld new flights in-situ. In both cases, a lot of resources and time are needed to complete the maintenance procedure.
