An apparatus for treating garbage and trash so that it may be reduced to compact form in bags, blocks or otherwise. The apparatus is typically placed at the bottom of a garbage chute and the apparatus breaks up the garbage into small pieces by means of a rotatable low speed high-torque motor-driven breaking drum running in cooperation with a matching anvil. The breaking drum has several rows of teeth which mesh with teeth-like anvil elements of the anvil, and the teeth on the breaking drum are so gapped as to provide a nip to trap and crush oversize bottles and the like. There are two torque-overload features. One torque-overload feature is an electrical overload device which can stop the rotation of the breaking drum if there is a jam, and carry out the cycle of reversing the drum, moving it forward again, and repeating the aforesaid a predetermined number of times and shutting off the machine after any predetermined number of cycles if the jam has not then been cleared. A second torque-overload feature involves moveable mounting of the anvil such that it can move away from operative position in the event of a jam. The anvil is normally held in operative position by hydraulic means and in the event of an overload the hydraulic means permits the anvil to move away from operative position and restores the anvil to its initial position when the jam is cleared. The apparatus also provides a check means in the form of a series of parallel check plates rigidly mounted on the frame of the apparatus. Each check plate is perforated so that it surrounds the breaking drum. Part of each check plate facing the breaking drum has an abrasive surface. The check means in combination with the other elements of the apparatus carry out the functions of clearing the breaking drum and its associated teeth of material adhering thereto which could cause clogging of the mechanism, which clearing of the drum includes scraping the breaking drum and grinding off tightly adhering material particularly material which may have strong fibers; the check means also prevents processed material from returning "upstream" and directs the flow of processed material into the bin or container so that the breaking drum exerts a "pumping" action on the processed material, so that the processed material may be tightly compacted in the bin or other container.
