Built from strong tensioned steel to withstand the most rigorous of screening requirements
The McDonald Range of Trommels are built on a strong support structure able to withstand the rotational rigors of the screening process. All drums are built from strong tensioned steel and built to withstand the most rigorous of screening requirements. Drums are mounted on steel support wheels and kept in position by main guiding wheels.
Driving wheels are steel and are fitted with taper roller type bearings. Guide wheels with polyurethane tyres are fitted at the discharge end of the equipment.
Further support and placement wheels are fitted at the discharge end of the equipment.
Trommels are typically fitted with twin geared units and speed is controlled via a single inverter giving flexibility in screening aggressiveness.
At McDonald International we have not resorted to lightening the structure to achieve small price savings but manufacture Trommels that are built to last many decades.
