The HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure grinding process. The machine reduces particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them.
In its essentials, a flotation cell must provide for two main functions. First, it must supply air adequate in quantity and quality for satisfactory process kinetics. Air quantity can be defined on the basis of the narrow range provided in major U. S. commercial cells, for escape velocity, which averages near 1.2 m/min (4 ft /min).
Understanding flotation technology. CoarseAIR™ flotation allows customers to increase the grinding size going to filtration. This technology makes it possible to recover coarse particles lost in conventional flotation — ultimately optimising energy input and providing sustainability benefits.
The KREBS High-Pressure Knife Gate Valve is a heavy-duty, wide-body, slurry knife gate valve designed specifically for highly abrasive applications. It features a full-port, open-body design, which allows the gate to create a path for solids to exit through the bottom of the valve as it passes between the massive elastomer sleeves.
