Due to the large amount of build-up and wear in areas of the conveyor belt, the client chose to use 40mm thick rubber lagged rollers. However, the 40mm thick rubber lagged rollers were extremely heavy and needed to be replaced every 6 weeks due to excessive wear on the shell.
The client trialled both Weartech and Weartech+. Both Weartech products are 45% lighter and resulted in a significant increase in roller life as summarised below.
