Ceramic Composite Impact Blocks

Rubber Wear Plates KRAM Engineering (Pty) Ltd smooth rubber plates are available in widths of up to 1300mm, lengths up to 2000mm, and overall thickness available up to 100mm. A steel backing plate is supplied with thickness varying from 3mm depending on the rubber thickness and / or application. Hole drilling is done to a standard pattern but special drilling according to customer requirements is available.

Rub–Cer Wear Plates
This is a new generation composite product combining a very high wear resistant surface of cylindrical alumina ceramic pellets bound within a resilient rubber base. The extremely hard ceramic surface provides exceptional resistance to wear, while the elastic property of the rubber dampens the impact forces.
The fact that each ceramic pellet is completely surrounded by rubber enhances the already outstanding wear resistant properties of the ceramic surface. The increase in liner life can vary from 4 to 12 times, depending on the application. Replacement of liners in difficult areas is both costly and time consuming, whilst the loss in production can often exceed the cost of the wear plate.
The increased liner life achieved using this product will more than compensate for the additional cost of the plates.

Application Areas

  • Feeders
  • Scoop Feeders for Mills
  • Screen Feed Plates
  • Launders
  • Feed Chute for Grinding Mills
  • Mill Discharge Chutes
  • Screen over / undersize chutes
  • Conveyer belt deflector plates
  • Conveyor transfer points

Profiled Rubber Wear Plates
There are many applications where the material flow strikes the wear surface at sharp angle. This reduces the dampening effect of the rubber, resulting in increased rate of wear. If the lining material is profiled, the material will impact on the rubber wear plate at a more favourable angle (i.e. as close to 90 as possible).
This correction will dramatically reduce the wear rate and significantly increase liner life. Steel backed profiled rubber is available in widths 400mm, 500mm or 600mm and a length of 1250mm. Total thickness is either 80mm or 120mm, including a steel backing plate of 5mm. Hole drilling is done to a standard pattern.
Attachment can be through bolts with washers and nuts on the outside of the steel structure, or a welded stud if through bolting is not possible. In both cases the holes are sealed after fitment with rubber plugs.
