The ceramics in these applications are generally produced from a high purity (99.8%), high density alumina. The components are manufactured by using slip casting or pressing and a high temperature firing process.

Rojan's ceramic products offer significant advantages over steel alternatives, such as:

Weight reduction

Increased wear life (approximately x10)

Reduced maintenance

Dirtwhacker Conveyor Belt Scraper

The Dirtwhacker conveyor belt scraper system has been developed in South Africa and has been a recent finalist in the Conveyor Association Awards. The Dirtwhacker operates by a simple but clever mechanism which allows the scraping blades to maintain constant blade/belt pressure across the full belt width. The operating principle of the Dirtwhacker involves the pressurisation of a rubber sleeve which alters the angles within parallelogram modules. The blunt scraper blades, which do not damage the rubber, are maintained at a constant pressure on the belt. This ensures a squeezing action on the belt rubber, encouraging the dirt to drop off the belt before it reaches the blade, therefore minimising any carryback.

Tungsten carbide blades provide exceptional wear resistance and the self-adjusting nature of the Dirtwhacker ensures low maintenance. The Dirtwhacker has been a highly successful product for Rojan and is now installed in over 100 applications in Australia.  We carry stock to suit belt widths ranging from 450mm to 3000mm and can be installed by Rojan personnel if required.
