CERAMIC LAGGING

DESCRIPTION

Ceramic lagging can be when there’s a requirement for:

  • More grip than what rubber lagging provides.
  • Longer service life as a result of higher wear resistance than Rubber.
  • Ceramic lagging with dimple tiles is used on drive pulleys to increase grip
  • Ceramic lagging with smooth tiles is used on non-drive pulleys to increase wear resistance/service life.

The ceramic tiles provide optimum grip on pulleys subject to high stress. Ceramic material is suitable for pulley lagging, due to its specific properties of extremely high wear resistance provided by aluminium oxide (Al2O3). It replaces traditional materials, because it provides increasing service life of pulley laggings.

APPLICATION

Elastotec ceramic pulley 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 pulley 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.

DESIGN

Elastotec ceramic lagging has vulcanised alumina tiles on rubber with rubber bonded to 5 surfaces of the tile to ensure tile cushioning and better adhesion strength. Tiles provide high abrasion resistance. Rubber backing used is Elastotec rubber compounds abrasion resistant and flexible to provide flexibility to the tile.

Elastotec ceramic pulley lagging is made of a 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 finishing to provide an increased surface contact area that increases adhesion.

Elastotec ceramic lagging is 250 mm wide to ensure easy handling and application. It can be supplied in thicknesses from 12 mm to 25 mm. 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 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.

For hot vulcanised applications, ceramic lagging can be supplied in rolls together with rubber end pieces can be added to build your own strips.

In strips with rubber ends to fit pulley face widths.

KEY FEATURES AND BENEFITS

96% Aluminium oxide tile material provide extreme wear resistance.
Rubber compound blended with CN polymers provide outstanding adhesion to ceramic tiles, rubber and metal.
Buffed CN bonding layer and buffed edges for optimum cold vulcanised adhesion to the pulley.
Low sulphur rubber makes rubber hardness stable with age.
Ceramic tiles bonded to rubber on 5 sides to resist better tile cracking and pull out.
Tiles with raised dimples improved belt grip and tracking.
Smooth tiles to protect non drive pulleys from damaging the belt cover.
Can be hot vulcanised to the pulley to achieve best bonding to metal pulley shell.
Supplied in strip form 250mm wide easy install.
Supplied in long rolls up to 50 m to reduce waste and be more cost effective and reduce stock requirement quantity as one roll fits all pulley widths.
Tile pattern in 100mm segments can be used on all pulley widths.
Can be supplied in cut to size strips with rubber ends to suit customer preference.
Cutting sipes allow adjustment of strip width to suit pulley diameter.
