         21 . A system for removing a coating material from another material, comprising:
 a staging hopper;   a second elevator operatively connecting the staging hopper to a decoating mill;   the decoating mill having a decoating mill tank and at least one rotary blade oriented within the decoating mill tank, wherein the at least one rotary blade can translate horizontally and vertically;   a screen station having a dump hopper and a recovery tank, the screen station operatively coupled to the decoating mill to receive a decoated slurry from the decoating mill;   a washer that is operatively coupled to the dump hopper to receive a decoated material from the dump hopper;   a dryer that is operatively coupled to the washer to receive the decoated material from the washer;   a washer aspirator that is operatively coupled to the washer to receive the decoated material from the dump hopper and to output the decoated material to the dryer;   a dryer aspirator that is operatively coupled to the dryer to receive the decoated material from the dryer and to output the decoated material;   a large waste water filter press that is operatively coupled to at least one of: the recovery tank and a settling tank, to receive a coating sludge from at least one of: the recovery tank and the settling tank;   at least one process water filter press that is operatively coupled to at least one of: the large waste water filter press, the washer, the dryer, the recovery tank, and the settling tank, to receive and filter process water from at least one of: the large waste water filter press, the washer, the dryer, the recovery tank, and the settling tank;   a sanitary water filter that is operatively coupled to at least one of: the large waste water filter press, the washer, the dryer, and the settling tank, to receive and filter water from at least one of: the large waste water filter press, the washer, the dryer, and the settling tank;   a water separation system that is operatively coupled to at least one of: the washer and the dump hopper to receive decoated material from at least one of: the washer and the dump hopper;   a staging tank that is operatively coupled to at least one of: the decoating mill, the recovery tank, the washer, a water tank and a heating tank;   a water heater operatively coupled to the heating tank to heat contents of the heating tank; and   a process chemical feed system operatively coupled to the decoating mill to deliver process chemicals to the decoating mill.   
     
     
         22 . The system of  claim 21 , the decoating mill having an inspection port. 
     
     
         23 . The system of  claim 21 , further comprising a collection container operatively coupled to the aspirator coupled to the dryer so that decoated material may pass out of the aspirator and into one or more collection containers. 
     
     
         24 . The system of  claim 21 , the staging hopper being gravity fed from the top with coated material.
