With the proven H-type pre-cleaner (Figure 1), the FLEXCO Europe GmbH range includes a solution which enables users to significantly increase the productivity of their conveyor systems. The innovative solution can be used, e. g., in coal and iron ore mining. Fitted with 200 mm long, individually mounted cleaning blades, the H-type always rests against the belt in an optimum manner, thus enabling it to be cleaned extremely thoroughly.
Carryback, that is to say material which remains sticking to the conveyor belt, is a cost factor for the user which is not to be underestimated. The H-type belt pre-cleaner is designed for fitting to the head pulley and removes the majority of carryback from the conveyor. The efficient pre-cleaner has proved its worth particularly in the coal, iron ore, bauxite and rock mining industry. The special feature of the unit is that the blades are individually mounted on vibration dampers. As a result, the modules are sprung independently of one another and adjust themselves individually as they wear. This ensures optimum contact at all times.
Depending on the application, Flexco supplies the H-type with high-strength carbide blades for vulcanised belts or low-wear polyurethane for belts with mechanical joints. These are supplemented by protected blades for applications with highly abrasive materials. As the blade is installed 15° below the horizontal centre line of the pulley, the blades do not lie in the conveyor discharge path. They are therefore protected against large pieces of rock and other debris.
The blades are designed either in a V-shape for vulcanised belts or as XF2 blades when used with mechanical connectors, although these are also suitable for use with vulcanised belts.
