Conveyor Control Monitoring & Protection

Mines, quarries, steelworks, power stations and processing plants are demanding environments. Hazards are many and varied and nowhere more so than where bulk materials are being conveyed in the presence of personnel. Incidents involving product spillage, misaligned or torn conveyor belts and other mechanical malfunctions can cause injury to staff as well as costly downtime, damage to machinery and loss of revenue.

Which is why Davis Derby has developed the MineWATCH range of conveyor protection systems. This comprehensive suite of safety and protection products includes pullkeys, belt alignment and tear sensors, spillage detectors and sequencing and slip rollers. There is also a speed monitor and a pease probe to alert you to hazards ranging from a blocked chute to unacceptable liquid levels.

Such is our expertise in this market sector that intrinsically safe products produced by our sub–contract facility are at the heart of many systems supplied by leading electronics brands in the UK, Europe and the USA.

All Davis Derby devices are compatible and easily installed by qualified electrical engineers on new or retrofit schemes. We can also offer you a bespoke design service for your conveyor control system.
