Industrial conveyor belt cleaning brushes are assembled by fixing heavy duty cage type castings onto a shaft, then fitting 12 metal back strip brushes into the six location spaces giving a brush overall diameter of 305mm and can be made in lengths of up to 4000mm long.
Left or right hand helical patterns are available.
Smaller castings are also available to give 250mm overall diameter. This type of construction has the advantage of using heavy duty helically formed strip brushes that can be refilled on site. Open cage type construction is ideally suited where brush clogging causes problems.
Brush units are usually mounted under the head drum so the rotating brush will sweep residue material away from the belt. Independent screw adjustment provides a simple method of brush adjustment.
Recommended brush speed is 3 x belt speed.
