RUBBER LAGGING
DESCRIPTION
Rubber lagging is the most commonly used pulley lagging. Rubber’s flexibility, it’s abrasion resistance and coefficient of friction make this material popular for increasing grip and reducing wear and corrosion of the pulley shell. Elastotec Rubber Lagging is engineered to be highly elastic, wear resistant and resistant to outdoor ageing to provide long service life. Through the use of the custom in-house rubber mixing process, Elastotec uses the highest quality materials to ensure the most durable rubber lagging available.
APPLICATION
Elastotec Rubber Lagging can be applied to conveyor drive, tail, snub, bend or take-up pulleys and is designed for use in medium belt tension applications. It is used for conveyor system applications in the mining, quarrying, mineral and metal processing industries but can be used on conveyor pulleys in any application where required. Elastotec Rubber Lagging has excellent wet and dry abrasion resistance, a high degree of flexibility for enhanced shedding of carry back and a high degree of protection for the conveyor belt.

CERAMIC LAGGING
CERAMIC LAGGING
DESCRIPTION
Elastotec Ceramic Lagging has vulcanised aluminium oxide tiles in rubber with rubber bonded to 5 surfaces of the tile to ensure tile cushioning and better adhesion strength. Tiles provide high abrasion resistance and rubber backing provides dynamic movement of the tiles.
Elastotec Ceramic Lagging is made of a two different rubber layers co-moulded together. The top layer is a high abrasion resistant rubber formulated for 100% rubber tear bond to the ceramic tiles. The bottom layer is the CN bonding layer for increased adhesion. Elastotec’s specially formulated CN bonding layer is engineered to achieve ultimate adhesion when bonded to steel pulley surfaces. A buffed finish provides an increased surface contact and increases adhesion force.
Elastotec Ceramic Lagging is 250mm wide to ensure easy handling and application. It can be supplied in thicknesses from 12mm to 25mm. Thicker rubber allows more deflection of the tiles under the load. This reduces the risk of excessive wear of the bottom belt cover.
APPLICATION
Elastotec Ceramic Lagging is used in applications that require reliable operation and long service life. Benefits include reliable grip/traction under all conditions and longer service life than can be obtained with rubber lagging.
Ceramic lagging with rubber backing allows the ceramic tiles to move and adjust their position in response to the movement of the rubber belt cover. This helps protect the belt from wear and damage.

WEAR INDICATOR RUBBER LAGGING
WEAR INDICATOR RUBBER LAGGING
DESCRIPTION
Elastotec Wear Indicator Rubber Lagging has been developed to provide mining companies with a long life lagging that will provide a visual indication when the abrasion resistant lagging has been worn away and the lagging should be scheduled for replacement. The coloured wear indicator layer is designed to indicate when the lagging replacement is required and to also provide protection for the pulley shell while lagging replacement is schedule.
Simple system that provides an easy to recognise visual indicator that the abrasion resistant diamond lagging layer has worn through and should be scheduled for replacement. Provides a margin of safety by identifying wear before contact/damage to the pulley shell occurs.
The primary aim is to prevent wear of the pulley shell that may lead to the need for an expensive replacement of the whole pulley. Many mines spend considerable time measuring the thickness of the lagging on the pulleys once in service to keep track of replacement requirements. This normally involves operators using ultrasound techniques on the pulley surface during shutdowns to record the remaining thickness of the lagging. A visual alarm while conveyor is running reduces likelihood of pulley shell wear as well as maintenance hours for lagging control.
FEATURES AND BENEFITS
- Rubber backing developed in conjunction with ARDL (Akron Rubber Development Laboratory) to retain flexibility at low temperature (50C).
- High performance abrasion resistant synthetic elastomer.
- Coloured wear indicator layer below abrasion resistant layer.
- Proven bonding system between abrasion resistant synthetic elastomer and CN backing coloured rubber.
- Coloured wear indicator (Blue for SBR and Red for FRAS).
- High quality rubber formulations designed for good bonding, resistance to degradation by out door exposure, and good abrasion resistance.
- To be applied though hot vulcanising method to eliminate the chance of lagging debonding from pulley shell and separation on joins.
- Can be supplied in a range of thicknesses (15,20 and 25mm).
- Suitable for long term service at temperatures from 40C to +70C.
