Abstract
An improved housing embedded in the ground for use in crushing of ore. The housing has a generally figure eight configuration in plan defined by a pair of hollow, upright cylindrical segments with a common wall between the points of intersection of the segments. One segment houses a dump pocket, an ore crusher, a surge chamber and a discharge feeder and conveyor in descending order, and the other segment contains drive machinery, dust control apparatus, a lubrication system, hoist ways, elevator shaft, and other service facilities. The crusher in the first segment is supported on a floor supported by the wall of the first segment itself. The housing requires only a minimum of concrete and reinforcing steel since the cylindrical configuration of the sections thereof provide the most efficient resistance to lateral pressures resulting from earth backfill and surcharge from heavy haul trucks.
