Abstract: A compost turning machine which travels along the ground and straddles a compost windrow, and which carries a rotating drum for turning the composting material. An adjustable auger system is located outboard and ahead of the rotating drum to collect composting material and deposit it in the path of the rotating drum. Each auger is independently driven by a hydraulic motor and can be individually raised or lowered as required.

Abstract: A continuous conveyor composting apparatus to provide a method of completely mixing semi-solid sewage sludge, compost material and refuse into a non-compacted, readily compostable material. A variable capacity mixing chamber is provided to receive a partially mixed product from several hopper bins which are equipped with variable speed auger systems. The mixing chamber is equipped with a compost-throwing member which mixably engages the product to lift, separate and fluff the material.
