Pulley Lagging

Designed, developed and manufactured in Australia for the harsh conditions of all mining industries.

The MATOLAG has been develop for the easy application for in situ and pulley OEM installations.

The design and profile of the MATOLAG gives excellence in water drainage between the face surfaces on the pulley drum.

Reducing material build up was also a major design criteria for the MATOLAG; the profile of the MATOLAG reduces the buildup of foreign materials, which long term will reduce the cause of belt tracking and conveyor belt wear.

The MATOLAG is supplied in 6.5 metre rolls with a width of 250mm as standard; this reduces the wastage and allows easy stocking for all maintenance suppliers.

MATOLAG can be supplied in either natural rubber or FRAS for the underground mining industry as per AS 1334.10-1994.

Quality Assurance

For each production batch of MATOLAG ceramic lagging, quality assurance tests are carried out to confirm that the rubber ceramic, the rubber metal and rubber to rubber adhesion is maintained at the highest level.

Tests Carried Out

  • Tests on rubber physical properties on every batch
  • Test on ceramic tile properties on every batch
  • Test on adhesion between the ceramic tiles and the rubber on every batch
  • Test on the cold vulcanised adhesion on every batch of rubber
  • Test on the hot vulcanised adhesion  on every batch of bonding layer

Rubber and FRAS Rubber Lagging

  • To prevent material wear of expensive pulleys, and provide positive drive between the conveyor belt and the lagging’s surface.
  • To remove excess water and keep a high level of co-efficient of friction between lagging and conveyor belt.
  • Easy replacement in-situ without removing pulley from the conveyor.
