Vibrating Rock Hopper with 500 Tonnes per Hour Capacity Ready for Delivery

Manufacturing of the vibrating rock hopper and its feeder bin has been completed. With a capacity of 500 tonnes per hour, this hopper is driven by 2 motors, each rated at 9.2 kW.

The hopper is the point where material entering the crushing and screening line is first received. It collects the run-of-mine rock tipped by trucks and passes it to the crusher at a balanced rate; if that balance cannot be achieved, every stage behind it has to cope with a fluctuating load.

What creates that balance is the fact that the hopper vibrates.

In a non-vibrating bin the material can arch, form a bridge and choke the flow. Vibration keeps the material flowing under its own weight, so the feed is not interrupted even with damp or clay-bearing run-of-mine rock.

The 500 tonnes per hour capacity is deliberately set above the capacity of the line itself. Because the hopper also acts as a buffer store, it prevents the crusher from standing empty when no truck is arriving. For this reason, hopper capacity is determined not by the hourly output of the line but by the gaps that open up between truck arrivals.
