  • Recycled material mixing machine
    Patent number: 7178972
    Abstract: A machine for combining powder material with cohesive site-won spoil has an input hopper which provides a preliminary breaking up step. Some lime is added from a lime feeder as the material is transported to a pan mixer. During transport a rotavator acts on the cohesive material so that finely divided material enters the mixing means. Further powder ingredients can be added to the components in the pan mixer by means of a powder ingredient supply system.
