Conveyor Belt and Conveyor Accessories Testing

Belt conveyors play a major role in bulk materials handling operations. They combine versatility and reliability and, in view of their inherent simplicity of operation, they are suited to the conveying of a wide range of bulk materials. They may be used effectively for the movement of bulk materials over both short and long distances. In the latter case, the adaptability of their design and construction permits them to operate over undulating terrain.

Belt Testing according to Australian Standards

Testing can be conducted for both steel cord belts and textile reinforced belts. The test procedures available for steel cord belts (AS 1333) comprise the determination of

• Steel Cord Pitch

• Cord Breaking F orce

• Static Pull-out Strength

• Laminate Adhesion

• Dynamic Cord Pull-out Fatigue Resistance

• Cord elastomeric Compound Penetration

For textile reinforced conveyor belts the following tests can be conducted:

• Thickness of Belting and Rubber Covers (AS 1334.2)

• Tensile Strength and Elongation (AS 1334.3)

• Troughability (AS 1334.4)

• Ply Adhesion (AS 1334.7)

• Resistance to Tear (AS 1334.8)

Tests for the rubber covers according to AS 1683 can be conducted for both belt types:

• Tensile Testing of vulcanised or thermoplastic Rubbers (AS 1683.11)

• Abrasion Resistance (AS 1683.21)

Conveyor Surcharge Angles

The actual belt surcharge angle for a bulk material sample can be determined on an existing fixed full size belt conveyor rig, comprising a 600mm wide, 62m belt conveyor, inclined at 4.5° or in a 1000mm belt stationary test facility utilising an oscillating idler frame with frequency control to simulate different belt velocities.

Maximum Conveyor Inclination Angles

The maximum possible conveyor belt inclination angle for a bulk material before slip-back occurs can be determined on a conveyor simulation rig. The idler set is oscillated with a given stroke and frequency level to simulate the idler action of a conveyor with a set idler spacing and sag ratio.  Individual belt speeds may be simulated by varying the frequency of the idler. The entire rig can be inclined while the idler set is oscillating and the angle at which the bulk sample begins to move relative to the belt marks the reliable maximum conveying angle.
