High pressure griding rolls

The High pressure griding rolls from the Enduron® series are fast becoming a go-to for greenfield projects looking to maintain their margins despite commodity price pressures.

On average, 53% of a mine site’s energy consumption is attributed to crushing and grinding ores accounting for almost 10% of a site’s production costs. Where the High pressure griding rolls technology has replaced traditional methods of crushing and grinding such as SAG or ball mills, customers have seen energy savings of up to 40%, and substantially improved mineral liberation.

Skewing is a vital feature for High pressure griding rolls as feed variance, segregation and the presence of tramp materials are inevitable in real world grinding circuits and will lead to uneven grinding and selective wear of the tyres. Skewing allows maximum grinding pressure to be maintained across all particles, while potentially damaging material passes through.

Other high pressure griding rolls equipment on the market use large lateral walls, or ‘cheek plates’, to reduce the materials exiting the high pressure area horizontally without being properly crushed. However, these cheek plates make it impossible for them to skew. By contrast, only the Enduron® high pressure griding rolls feature a spring-loaded lateral wall that skews alongside the rollers, maintaining a distance of just 1mm to prevent particles falling out the sides unreduced.
