The liners are energy efficient and ensure a very low grinding media consumption. Your key benefits: Optimum compromise between lifetime and grinding efficiency.
اقرأ أكثرGreatly accelerated liner wear due to high-energy impacts on the liner. For a 5m diameter mill these will be in excess of 8m.s-1, for a 10m diameter mill these exceed 12m.s-1. This causes high chrome liners to spall and crack and they may even fracture. This can reduce liner life from a year to less than a few months.
