System and method for crushing and compaction

摘要

An exemplary embodiment of a screw crusher may utilize a cantilevered screw with an inverse tapered shaft with flighting for conveying the product up the length of the shaft for compression. The screw may include an end flight configured to provide thrust to the product for further conveyance beyond the end of the screw or additional compaction when utilized with a receiving container. An exemplary embodiment of the screw crusher may utilize a single moving element in relation to a cylindrical tube for compression of the product. Also, an exemplary screw compactor may utilize a fixed replaceable restrictor tube section and an efficient screw design making it more cost effective and efficient to operate than other known compactors. Furthermore, an example of the screw crusher may be fitted with perforated or the preferred “V” Slotted tube to perform liquid removal in addition to the compaction of the material.

主权项

1. A system for crushing a material, comprising:
a compaction chamber including a proximal inlet portion configured to receive the material and a distal outlet portion having a substantially tubular geometry configured to allow crushed material to exit; and a cantilevered screw assembly having a shaft with a proximal portion at which it is cantilevered and a distal portion such that the shaft extends between the proximal and distal portions of the compaction chamber, a section of the shaft increasing in diameter in a proximal-to-distal direction such that a maximum diameter of the shaft is reached within the substantially tubular geometry of the distal outlet portion and the system is configured to crush the material between the compaction chamber and the section of the shaft that is increasing in diameter, the shaft further including a flattened portion extending from the section of the shaft that is increasing in diameter and that substantially maintains the maximum diameter of the shaft such that the flattened portion facilitates the crushing of materials to a desired thickness.
