Ervin & RAUCH: discover Amapure, the mineral additive to clean your metallic abrasives

RAUCH Landmaschinenfabrik GmbH is a global manufacturer of fertilizer spreaders, seed drills, and salt spreaders. Thanks to its precise distribution, the innovative RAUCH products allow farmers worldwide to provide crop nutrition that meets their needs.

Blasting with Ervin’s medium-hard grit and abrasive cleaning by Amapure took RAUCH’s surface pretreatment to a higher level.

Challenge
Ensuring that blasted workpieces are free of oil and grease before the coating is essential for quality assurance at RAUCH. Water drop tests performed on abrasive samples have revealed that the abrasive operating mix was contaminated by oil and grease from other areas of production.

Solution
An abrasive operating mix contaminated with oil and grease not only has high operating costs, but can also negatively impact productivity and coating performances. This is why RAUCH turned to Ervin’s Amapure – a mineral additive to clean your metallic abrasive - as a solution. Switching to Ervin’s latest product paid off in two ways: optimized surface pretreatment and, at the same time, a more economical blasting process. Lots of comparative tests with Amapure and competitor materials were performed by using a continuous overhead conveyor system with twelve blast wheels. The contamination in the abrasive caused by oil and grease was measured and documented daily over several weeks using the water drop test.

Results
Test results confirmed that Amapure led to over 50% better cleaning performance compared with the material previously used. This optimization ensured reduced operating costs and environmental impact (such as waste disposal). RAUCH found its ideal blasting solution with low consumption of Amasteel abrasive and Amapure degreasing additive made by Ervin’s team.
