Belt Cover Grades
Flame Resistant
Belts used in mining industry need to be chosen very carefully, because of the flammability of the work environment and the required level of safety. It is critical to use the right product, specific for the application.
There is a number of test methods for measuring the performance of the flame resistant belts. Derby reserved special space in its plant for keeping fire test devices, in accordance with EN 12882 and EN 14973.
