Overhead separators are suspended above belts or vibratory conveyors and magnetically lift ferrous materials out of bulk material.

Elutriator Elutriator Detailed Description The Elutriator is fed either by a band conveyor or vibratory conveyor and has a spring mounted vibrating fluidised bed with special patented stainless steel bed trays.

During the period these levels were worked, the "companion heading" for the shaker conveyor was only made in the north working.

In these first early days, the shaker conveyor on level 4 poured the coal production into a side crossing trough.

A companion heading was driven from level 9 to level 12A on the north side to accommodate a shaker conveyor.

A companion heading parallel to the main north haulage heading was driven to link level 14 to level 15, and a shaker conveyor was installed.

In the mine's early days, the shaker conveyor ran down the companion heading from level No. 1 to level No. 4 in both the north and south workings sections.

In that year, however, electrically-driven coal cutters and compressed air shaker conveyors were introduced to help remove some of the physical work required to mine and transport the coal from the face.
