WEAR COMPONENT™

  • WEAR COMPONENT™

WEAR COMPONENT™

Available in rubber (ML, SB) or with metal plates (IR).

APPLICATION
Dump trucks, unloaders, hoppers, skip loaders, conveyor chutes, feeders, etc.

 

  • The synthetic rubber used has excellent abrasion resistance, high tensile strength and tear resistance
  • Rubber elasticity absorbs shock, with little load fragmentation
  • Easy installation
  • Excellent noise prevention for improved work environment
  • Lightweight compared with metal liners, with easy and safe installation

◎:Block Liner applicable. ○:Install ML crosswise when a longer life is desirable.
△:Applicable. However, partial abrasion may occur. ×:Mold required.

 

Comparison with other Product Types

Type ML

  • Design with higher durability is possible with a higher bar height.
  • For the same area, Type ML requires less bolts than Block Liner does.

Type SB, Type IR (Block Liner)

  • The flat lining mostly prevents sticking.
  • The ease of installation is equivalent to a steel liner.
  • Partial repair is easier than that of Type ML.

Canvac®,Rubber Cloth

  • The continuous sheets mostly prevent sticking.
  • Easy to fit with a cone hopper.

Standard dimensions and combinations

When the descending speed of the dropped items exceeds 10 to 15 m/sec, the abrasion increases rapidly. In such a case, installing Type ML crosswise (perpendicular lining to the direction of the blocks) increases the angle of impact, which reduces the descending speed and the abrasion. When the belt is used in a section with especially severe abrasion, higher durability and economy can be obtained. There was an instance where changing the installation from longitudinal installation to crosswise installation with the same rubber liner specifications increased the life four-fold. The figure on the right shows crosswise installation of Type ML.

Selection of thickness of Type SB and Type IR (Block Liner)

Selection Example

When crushed rocks (specific gravity: 2.5) of 20 (cm) are dropped from a height of 1.5 m and the angle of impact is 60°, select the thickness as follows:

①Weight of the rock:
20 cm (depth) × 20 cm (width) × 20 cm (height) × 2.5 g/cm2 (specific gravity) = 20 (kg)

② Impact energy:
20 kg (weight of rock) × 1.5 m (drop) = 30 (kg·m) Plotting this as the impact energy of the vertical axis in the right figure, the point where it meets with the 60° angle of impact in the horizontal axis indicates that the liner thickness to select is 80 mm.
When the specific gravity is 3 or greater, or when the quantity of the processed items is significantly large, select a thickness thicker by one rank.

Comparison with other Product Types - Angle of Impact

  • The impact energy indicates the maximum weight (kg) × drop (m) of the processed item.
  • The angle of impact indicates the angle (α) in the right figure.
  • The graph for liner thickness selection in the upper right section shows the case when the specific gravity of the processed item is 3 or less.
