FUNCTION AND BUSINESS SECTORS
Self cleaning pulleys or Cage drum pulleys are conveyor drums manufactured with bars welded to the side flanges instead of the tube as on a standard drum. The main advantage of self cleaning pulley is that they prevent product caking and retention between the belt and the drum tube. The product drains through the bars directly into the drum.
At ALTEMA, cage pulleys are mainly used in the food industry, handling dry matter, cereals, grains and wheat. This type of self-cleaning drum pulley is also found in the quarrying sector and used on sand and gravel pits. The self cleaning pulley is generally installed in silos and elevators.
Implementation
There are 2 designs for the cage drum pulley.
- Standard design: The drum pulley is equipped with flanges on each side of the drum, which are manufactured with large openings to allow product overflow as it enters the drum.
- Design with discharge cone: The design is different in that cones are attached to the inside of the drum to facilitate product discharge from the sides.

Manufacturing methods cage pulley
There are 3 types of bars installed on the cage pulley :
- The ALTEMA standard for the manufacture of squirrel-cage drums: the welding of round bars to the flanges.
- The use of square bars instead of round ones.
- Rectangular dishes can also be welded.
Depending on the type of bars installed, and when they need to be curved, two options are possible: either the whole assembly is machined curved after assembly, or the bars are curved before (or during) installation and welding.
