ABSTRACT:
The present invention contemplates a multi-level collection area of solid waste products. On a top level of the collection site, ramp ways for trucks are provided so that the trucks may dump solid waste into a central collection opening. Gravity feeds the solid waste into a centrifugal spinner. The spinner includes radial agitator blades. The solid waste is spun and agitated on the spinner and centrifugal force tends to push the solid waste to the outer edge of the spinner. The spinner angles upward from the center to an outlet slot of uniform size disposed about the circumference of the spinner. A cover is disposed over the spinner having a plurality of fixed teeth disposed thereon. The combination of the cover and spinner is such that as larger pieces of solid waste are propelled towards the outlet slots, they are acted on both by the spinner and the blades of the cover, reducing them to a size small enough to fit through the outlet opening. The continuous rotating action also aids in preventing the clogging of the outlet opening. The centrifugal force of the spinner pushes the articles through the outlet slots and into a series of collection bins. The collection bins may include screens or filters for further controlling the size of the solid waste particles. Runways are provided beneath the bins for access by trucks. An opening in the bottom of the bin is used to release the uniform size solid waste particles into the truck for transportation to a land fill site. The uniform and small size of the solid waste particles results in improved mixing characteristics with earth, thus a uniform compaction with a minimum of settlement in the land fill, increasing the likelihood that the land fill will be suitable for uses requiring load support capabilities. Moisture is removed from the processed solid waste by a combination of grinding and centrifugal force. The bottom of the storage bins is pitched and includes as sieve so that any liquid exiting the outlet slot will flow through the sieve and be transported away from solid waste. By substantially reducing the liquid content of the solid waste, the land fill volume will have fewer organic fluids and liquids, reducing the amount of leachaids and the formation of methane gas.
