Going underground: To scalp or not to scalp?
The most compact way to scalp is with a vibrating grizzly feeder. However, using a separate feeder and a scalper allows both components to be optimized for improved process control and performance. Points against scalping: A separate scalping grizzly adds a new piece of equipment into the process, increasing capital costs and requiring maintenance.

mining engineering: Conveyors and Feeders
Hard rock mine belt conveyors normally require the ore to be crushed before it is conveyed or at least broken enough to pass through a grizzly opening. Run-of-mine (ROM) material is not normally conveyed except for short level runs. The finer the ore is crushed, the longer the belt life, the more reliable the system, and the lower the operating

Mine personnel must halt production to dig out the boulders, or use rock breakers to clear the obstruction, creating a bottleneck and further decreasing production.” Motion Metrics says a common misconception is that a grizzly can eliminate the problem of oversized material.
