►Brief IntroductionSidewall belt conveyor is continuous transporting equipment of loose bulk materials such as coke, coal, limestone, sand and gravel. It adopts high quality conveyor belt with corrugated sidewall and horizontal baffle. Sidewall belts are used to convey material up inclines. The sidewall increases the carrying capacity of the belt and prevents product from falling off the edges of the belt. Hot vulcanization provides a 5x greater adhesion between the belt and sidewall, eliminating the need for bolting the sidewall to the base belt. Greater adhesion also prevents the sidewall from lifting and separating from the base belt, extending the belt life.

►Features
   1.Long service life
   2.Reduced maintenance
   3.Low power consumption
   4.Reduced number of transfer points
   5.Quick installation and quiet running

►Advantages

   1.Flexible transportation – can convey all kinds of bulk materials such as coal, ore, sand, fertilizer and grain in horizontal, oblique, vertical or other angle directions. 

   2.High tensile strength

   3.Increases belt capacity

   4.No spillage with steep angle conveying

   5.Decrease necessary conveyor footprint

   6.No transfer points- the belt are capable of turning at any angle right from feed hopper to discharge point

   7.Maximum utilization of space – able to convey material at angles up to 90 degree

   8.Decrease maintenance costs with fewer drive units and components

   9.Long lifespan

   10.Low power requirement – requiring low power to move loaded belts

   11.Quiet smooth running – as belt runs on rotating idlers, low resistance is achieved that in turn ensures quieter operations

►Application

   1.Coal and wood-chip fired power stations

   2.underground mining (coal and ore)

   3.Shaft conveying for tunnelling and underground mining

   4.Steel industry

   5.Ship loading and unloading, ship to ship loading

   6.Sand preparation in foundry plants

   7.Silo feeding

   8.Slope conveying in openpit mining

   9.Waste recycling, soil purification and water treatment

   10.Handling of large material flows in the horizontal path

►Working Principles

The horizontal loading section a deflection wheel bends the belt into the feeding of the bulk material takes place on a mostly horizontal feed path, where the side wall belt is supported by loading impact idlers. The feeding of the conveyed material can be achieved by direct feeding from a hopper, over a chute, a feeding belt or a feeding pulley. The selection of the optimum feeding station depends on the properties of the bulk material and the belt speed of the vertical conveyor. The upward and downward strands are encased from the bottom to the top. Substructures or support rollers are not necessary in this section.

The vertical section leads over a deflection curve into the horizontal discharge section. The deflection curve is made up of a number of high specification pulleys. These pulleys experience the vectored load of deflecting the belt tension from vertical to horizontal. 

At the drive pulley, the bulk material is discharged and the belt is returned to the back going strand. Depending on the bulk material properties, the drive pulley is followed by a beater wheel for belt cleaning in the return side. The beater is self-driven. Material that fails from the belt goes into the main delivery chute. Lateral deflection wheels turn the belt from the horizontal back to the vertical.

►Selection condition

1. What is the conveying material and its physical characteristics? such as bulk density, feeding size, temperature, mositure content etc.

2. What is the processing capacity of the conveyor?

3. What is the inclination angle of the conveyor?

4. What is the lifting height (distance between inlet and outlet)?

5. What is the length of horizontal section?

►Maintenance

    1.Idlers: These must rotate freely, and be free from any material build-up. Lubrication of all moving parts on a planned basis is essential for dependable operation and minimum maintenance. Component life will be extended by following the manufacturer lubrication instructions.

    2.Pulleys: These should be free from any material build-up. The lagging on the drive pulley should be inspected on a regular basis. If the lagging is in poor condition it may be necessary to apply more tension than is normally necessary to drive the belt resulting in premature wear.

    3.Deflection Gear: Again, these must be free to rotate freely.

    4.Feed Hopper: It is important that this is just free from the top of Sidewalls, any rubber seals around the hopper need checking for wear to prevent excessive dust or spillage.

    5.Tracking: The belt should run without touching any side members or deflection gear, please refer to the section on belt tracking if the belt is running out of alignment.

    6.Good housekeeping: This is necessary for continuous operation and low maintenance. Spillage and build-up of material can eventually cause the idlers to stop rotating and an accumulation of lumpy material can cause belt damage.

Check: The belt edges, Sidewalls, Cleats and the belt splice need to be checked on a periodic basis for wear or separation. Any minor areas of damage should be repaired as soon as is possible.
