Glossary of the bulk material handling belt conveyor system.




Glossary Term Detail Url
Absorbed Power The power seen by the output shaft of the reducer. This power is derived from the conveyor itself and is normally given by the effective tension (kN) multiplied by the conveyor belt speed (m/s). Te x S = Pabs (kW) Link
Approved Approved by the Engineer in writing. Link
Bearing journal that part of the pulley shaft or axle that is in contact with, or enclosed by, the bearing(s) Link
Belt cleaner Devices positioned to remove material from a conveyor belt, which did not naturally release from the belt discharge point. Link
Demand Power The power required at the motor shaft. Link
Design Drawings Fully dimensioned drawings prepared by the Engineer, showing all members with their size, material grade, special connections, combination of forces to be developed in member connections, any cambers and eccentricities, and any other information required ... Link
Design Power The power derived, including factors, for comparison with the Reducer Rated Power. Link
Engineer The company responsible for the structural design, for preparation of the Design Drawings (or approval of Design Drawings prepared by others), for accepting the Fabrication Drawings and erection method statement and, where applicable, inspection of constr... Link
Fabrication Drawings As defined in SANS 2001 Part CS1 Link
Fiery mine A mine in which the seam or seams of coal being worked give off an amount of flammable gas, or mine in which there is a danger of explosion due to coal dust or flammable gas , or a gassy mine which is a mine where gas ignitions and outbursts have occurred... Link
Input Power The power required at the reducer input shaft. Link
Installed Power The electrical power or nameplate power of the motor. Designated Pmot it is normally the next larger size of motor compared to the Demand Power. Link
Intersection Point (I.P) The projected point in plan view of 2 conveyor system transfers where the centerlines of the belt intersect. Link
Left hand side of conveyor The side if a conveyor which is on the left of passenger riding on a conveyor belt facing in the direction of travel. Link
LHD The Load Haul Dump truck is a specialized loading machine specifically designed for underground transportation of equipment and ore. Link
Live Shaft Pulley A live shaft pulley has external bearing, normally housed inside a plummer block bearing housing arrangement. The shaft will turn with the pulley. Link
OEM Original Equipment Manufacturer Link
Owner Legal owner of structure, or company benefiting from the use of the structure Link
Series designation of the size of an Idler shaft. Indicating the shaft diameter at the bearing journal and shaft end. Link
Steelwork Contractor As defined in SANS 1921 Part 3 Link
Time Constant It is defined as the amount of time it takes for the change in velocity to reach 63% of its final value. Link
Transfer Chute Plug or Blocked Chute A plugged chute or blocked chute device provides belt protection at the discharge end of the conveyor into a transfer chute. Blocked flow can result in damage to the moving conveyor. A blocked chute can also cause severe damage to the belt being fed, part... Link
Transition area The area between the tail pulley and the first full toughing idler. The area where the belt makes its transition from the flat profile of the tail pulley to the troughed from necessary to match the toughing idlers. Link
Wear plates Plates of wear resistant material, placed in strategic location to absorb the abrasive wear of the material transfer system. Usually replaceable Link
ROM Run of Mine Link
Head Section A general term referring to all of the equipment associated with the discharge area of a conveyor system Link
SCADA Supervisory control and data acquisition Link
Transition idlers special idlers where the throghing angle and height of the rollers can be adjusted to match the transition geometry of the belt Link
Surcharge Angle Angle to the horizontal which the surface of the material assumes while the material is at rest on a moving conveyor belt. Link
Bulk density Bulk density is the weight of a material in a given volume. Link
Repose Angle The angle of repose, or critical angle of repose, of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping. Link
