"Since first being shown at Hillhead ’99, Chris Harper Associates’ Smart rotary-brush cleaning system for conveyor belts has successfully been used on a number of applications in the quarrying industry; clients include Lafarge Aggregates, Omya UK, Tarmac Central, Tarmac Western and Tarmac Southern. However, as the industry becomes more aware of environmental issues, more and more units are now being used at a variety of recycling sites and on waste-processing plants."
"The brush can be used to clean both flat and chevron-type conveyor belts and works effectively on worn, damaged and new belts. Operated by the linear motion of the belt, the patented Smart system requires no external power source. Adjustment of the system is completely automatic, maximizing brush life while minimizing maintenance."
