Abstract
A particulating apparatus for liquid filled plastic containers in preparation for recycling produced plastic particulate. The particulating apparatus includes a container hopper for accepting a supply of plastic containers to be processed by the particulating apparatus wherein at least a portion of the containers are partially liquid filled. There is a transport for conveying the supply of plastic containers from the hopper to a pulverizer. The pulverizer has a pulverizing chamber within which a pulverizing means is housed for reducing the plastic containers to plastic particulate. The chamber includes means for draining liquid held within the containers to a liquid collector. A conveyor means is provided for transporting plastic particulate from the pulverizer to a collection bin where the particulate is retained for further processing or disposal. The conveyor means is inclined at least partially vertically upwardly from horizontal to permit drainage of additional liquid from the particulate. A method of particulating liquid filled containers into particulate is also disclosed that includes supplying containers, at least a portion of which contain liquid, to a pulverizing chamber…
