The mining industry uses heavy duty belt conveyor for transportation, production lines and production departments. They are used mainly for transfer raw materials in a horizontal or inclined conveying system such as coal, gravel, sand, cement, grain, rocks and are made from a main belt supported by conveyor rollers or conveyor idlers in single lane or in a troughing type series.

Conveyor Rollers or Conveyor Idlers for the mining industry
Conveyor Rollers are built for strength, durability, and low noise-level. A free-wheeling roller design eliminates misalignment of the shaft and high quality conveyor rollers are usually fit with adjustment screw to provide easy adjustment.
Structural resistance and roller stiffness are also very important when choosing your conveyor rollers. Look for conveyor idlers made of high quality aluminum for reduced weight and no increases in weight.
Another important characteristic to look for in your conveyor idlers is the type of oil or grease use in the cartridge. A warm or tropical climate usually requires a grease-type mechanism whilst an artic weather climate will work better with oil type mechanism.
Conveyor Belt Rollers Maintenance
Contact us to discuss your requirements of Mining Conveyor Rollers. Our experienced sales team can help you identify the options that best suit your needs.
The mining conveyor belt and rollers will require more frequent maintenance compared to more traditional industries as the weight and the volume moved by the conveyor is usually much higher as is the presence or dust and various other rubbles. Make sure you perform maintenance when there is abnormal noises, loose conveyor rollers, running deviation situation, motor reducer lubricant.
Post time: Aug-17-When I model a bulk material conveyor belt, I use a series of surface lofts and sweeps to generate the inside of the belt. I then thicken it to match the real-world thickness.
I normally constrain an empty part file at the conveyor assembly origin, then project key assembly geometry into sketches in the part. I include the head pulley, tail pulley critical return idlers, and the centerlines of any troughing rollers that control the belt shape.
I use swept surfaces where the belt cross section is constant, like between the head and tail pulleys, or between the first and last 35 deg idlers. When the belt transitions between troughing idlers and the head/tail pulleys, I use a surface loft. I make sure that the straight sketch has the same number of line elements as the troughed cross section to build the loft. I use sharp corners between the straight section and the troughed section. I normally use a sketch at the tail pulley to establish belt width. It is important to use projected geometry and sketch constraints at each critical point to have a single dimension that controls belt width.
Once I have all the surfaces for the full belt path, I stitch them into a single quilt/surface. I then add rounds at any sharp corners, or non-tangent joints.
The final feature in the model is a thicken to create a solid belt model.
