Hot Vulcanised lagging application involves the chemical cross-linking of five reactive layers during the autoclave curing process. To achieve the
In November 2017 a major iron ore port facility in the Pilbara decided to replace the ceramic lagging on a
Spare pulleys are held so that in the event that an operational pulley requires replacement this can be done quickly
Catastrophic lagging failure due to debonding occurred within two weeks of installation and operation of the pulley, resulting in a
Lagging can be of good quality and application can be correct, but lagging can still fail and does. Everything seems right but the lagging still doesn’t perform to expectations. So why does this happen? It’s because the lagging selection is not right for the application.
Elastotec extreme diamond rubber lagging is designed for drive and non drive pulleys that require extended service life.
At Elastotec, we engineer lagging solutions that keep conveyors running. Here are some causes of lagging failure.
Elastotec Direct Bond Ceramic Lagging - application system designed to improve adhesion consistency, reduce lead times, reduce glue wastage and labour time.
Ceramic Lagging is specified when there is a requirement for:
Elastotec Ceramic Lagging can be applied to conveyor drive, tail, snub, bend or take-up pulleys when there’s a requirement for more grip than what Rubber Lagging provides or longer service life as a result of higher wear resistance than rubber. Ceramic Lagging is used for pulleys operating under extreme conditions. It is suitable for wet, clay-containing, muddy and abrasive materials. Also for belts under very high tension. Especially suitable for drive pulleys subject to extreme wear to eliminate slippage.
Elastotec Ceramic Lagging consists of vulcanised alumina tiles bonded onto rubber.
The rubber is bonded to five surfaces of the tile to ensure tile cushioning and better adhesion strength. Tiles provide high abrasion resistance. Flexible rubber backing containing Elastotec rubber compounds is used to provide abrasion resistance and ﬂexibility to the tile.
Elastotec ceramic pulley lagging is made using two different rubber layers extruded together. The top layer being the high abrasion resistant layer to which the tiles are vulcanised onto and the bottom layer being the adhesion CN bonding layer. Elastotec’s specially formulated neoprene based CN bonding layer is engineered to achieve ultimate adhesion when bonded to steel pulley surfaces. Elastotec’s CN bonding layer has a buffed ﬁnish to provide an optimum surface contact area that 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 belt. This property provides additional reserves with extreme belt tensions, especially in combination with fabric belts with high elongation or low cover thickness on the running side.
It can be supplied in 3 formats:
1.In long roll lengths that fit on standard sized pallets to eliminate waste and for cost effective transportation and storage. Ceramic Lagging in rolls can be cut to the pulley face width length to have a full face width ceramic coverage.
2.For hot vulcanised applications, Ceramic Lagging can be supplied in rolls together with rubber end pieces, which can be added to build your own strips.
3. In strips with rubber ends to ﬁt pulley face widths.
