Abstract

A mixing machine operable to receive quantities of waste material and an inert material in separate hoppers for conveyance to a mixing chamber for uniform mixing thereof in prescribed ratios is disclosed wherein each hopper is provided with rearwardly directed augers to pull material away from the opening from the hopper to the mixing chamber. The mixing chamber includes a rotatable flail rotor operable to engage the supplies of materials being fed thereto and effect a mixing thereof prior to being discharged to a mixing auger for final mixing of the two materials before discharge from the machine. Each component of the machine is hydraulically driven to provide independent operation thereof relative to any other component of the machine. An additive hopper is also provided to discharge a selected amount of an additive into the mixing chamber for selective neutralization of the waste material.

Dependent claims

A mixing machine for homogeneously mixing two solid materials, comprising:

a support frame;
a mixing chamber centrally mounted on said support frame;
a first hopper mounted on said support frame for holding a supply of a first material on one side of said mixing chamber, said first hopper having a first conveyor means for moving said first material from said first hopper through a first discharge opening into said mixing chamber;
a second hopper mounted on said support frame for holding a supply of a second material on the opposing side of said mixing chamber from said first hopper, said second hopper having a second conveyor means for moving said second material from said second hopper through a second discharge opening into said mixing chamber;
rotor means rotatably supported within said mixing chamber to engage both said first and second materials entering said mixing chamber and to effect both a comminuting and a mixing of said first and second materials while in said mixing chamber to form a mixed material, said rotor means further being operable to discharge said mixed material through a discharge opening in said mixing chamber;
discharge means supported from said support frame in flow communication with said discharge opening in said mixing chamber to receive said mixed material from said rotor means, to effect a further mixing of said mixed material, and to effect a discharge of the mixed material remotely from said machine;
and
power means operably connected to said first conveyor means, said second conveyor means, said rotor means, and said discharge means to drive the operation thereof.
