Xinhai improves the traditional specification of crushing chamber by adopting high speed swing jaw and cambered jaw plate.
High-speed hammer impacts materials to crush materials. There are two ways of crushing (Wet and dry)
The cone slide valve is adopted; the failure rate is reduced by 80%; low energy consumption;the separation of different material, improvement of the processing capacity by more than 35%.
Cylindrical energy saving grid ball mill is lined grooved ring plate which increases the contact surface of ball and ore and strengthens the grinding.
20-30%. Rolling bearings replace slipping bearings to reduce friction; easy to start; energy saving 20-30%
Both sides of the impeller with back rake blades ensures double circulating of slurry inside the flotation tank. Forward type tank, small dead end, fast foam movement
