SELF CLEANING PULLEYS
The self cleaning pulley is manufactured with bars welded to the side flanges instead of the tube as on a standard drum.
TAIL PULLEY
A tail pulley is positioned on a conveyor when it is transporting a material that will tend to stick to the conveyor belt.
IDLER DRUM
To meet specific needs on belt conveyors, ALTEMA can manufacture customized idler drums, also known as conveyor rollers.
CUSTOM DRUMS
Custom drums are produced on the basis of drawings supplied by customers, and can also be modeled in the design office.
Specific drum design
ALTEMA’s design office can take charge of modeling your special drums using 3D CAD software (Solidworks). Thanks to the calculation software, he can also manage the sizing of your special drums (beater drum, squirrel cage drum, etc.) and help you optimize them: material, size, geometry, thickness and type of connection. For any specific request, please contact ALTEMA to discuss the best technical solutions.
LINKING SYSTEMS for self cleaning pulley
ALTEMA offers various types of connections: Vecobloc hubs, flange bearings, shrink discs, etc.
CLAMPING RINGS
The radial deformation of the elements forming the head of the clamping rings ensures contact between the flanges and the shaft on a self cleaning pulley. Each part comes into contact with another at a specific angle, generating a pressure force and causing the discs to contract.
VECOBLOC HUBS
VECOBLOC removable hubs are the most practical system for securing the drum to its shaft without the need for special tools. ALTEMA offers a wide range of removable hubs to meet all requirements.
