Wear reduction in concrete production
and concrete transport

Whether in concrete production or concrete transport and delivery, wear occurs on all metal parts that come into direct contact with moving ingredients or the finished product. It starts with the supply of the binder cement and aggregates: such as sand, gravel or crushed stone in various grain sizes. Strong concrete requires rough, angular sand grains. Precisely this concrete sand has strong abrasive properties. But gravel and ready-mixed wet concrete itself also cause rapid wear on metal parts.

To slow down wear and tear on conveying equipment in the concrete industry, we coat landfill hoppers with 50Shore, 60Shore A and Para impact-resistant rubber or Wearprotect PU (Polyurethane), materials with the added benefit of noise dampening. Conveyor belts receive side guides made of sheets of synthetic rubber, while we provide transfer points with Racloprema natural rubber and possibly Feraser belt scrapers. We also apply Racloprema in the weigh bunker. The remaining parts get cheaper, synthetic rubber. We do cover bypass and outlet again with Racloprema natural rubber, while we make outlet funnels more wear-resistant with Wearprotect PU, among other things because of oil resistance. We usually supply outflow funnels made to measure, ready to assemble in serially molded highly wear-resistant polyurethane. Also in the truck mixer, we cover the inlet and outlet shells with Wearprotect PU. For the auto concrete pump, we have a complete product package against wear, including special PU anchor balls. These offer a service life and shape retention many times better than that of the traditional rubber variants.

In the processes of mixing and rinsing, we can – depending on the type of concrete – clad mixer walls with wear-resistant building board, welded-on plates, castings or wear-resistant aluminum oxide ceramics. We manufacture custom blades, wipers and wirblers from polyurethane or wear-resistant castings. By the way, this also applies to the vanes of machines for rinsing and washing residual concrete. To extend the service life of the machines, we replace the standard blades supplied by the machine builder with custom-made wear-resistant polyurethane blades. If required, we can weld up elevator buckets with wear-resistant welding wire from the WearProtect LTM program for significant tool life extension.
