A material processor having an enclosure with an ingress to receive material into the enclosure, and a discharge to remove material from the enclosure. A spindle is located in the enclosure, has a longitudinal spindle axis, and is rotatable about the spindle axis. A drive is operatively connected with the spindle to rotate the spindle about the spindle axis. A centrifugal sieve is located in the enclosure and coupled with the spindle. The ingress feeds material into the sieve. A conveyor is connected with the discharge to transfer material from the enclosure. The conveyor further has a generally cylindrical tube with a tube diameter, two opposing ends, and a tube axis extending through the ends. A helical blade extends along the tube axis between the two ends and is rotated about the tube axis. More particularly, the helical blade may have a series of blade tips that are spaced along the tube axis. Adjacent blade tips may be spaced apart by a distance that is less than or equal to about one half the tube diameter. Further, the helical blade is rotated at high speed, more specifically, between about 600 to about 1500 rpm. A volumetric ratio of material conveyed in the conveyor as compared to the internal volume of the conveyor is between about ten to about twenty percent. Additionally, the tube may include first and second tube sections that are coupled together with a clamp ring. The first section may have a male end with a male flange, while the second section may have a female end with a corresponding female flange. The male and female ends and flanges abut one another to define a generally truncated V-shaped ridge that extends outward from the tube with opposing, inclined surfaces. The clamp ring overlays and presses inward upon the inclined surfaces to cam the male and female flanges and ends together.

[ What is claimed is:] [1.]1. A material processor comprising:an enclosure, the enclosure having an ingress through which material is received into the enclosure, the enclosure also having a discharge through which material is removed from the enclosure;a spindle rotatably mounted within the enclosure, the spindle having a longitudinal spindle axis about which the spindle rotates;a spindle drive operatively connected with the spindle, the spindle drive rotating the spindle about the spindle axis;a sieve operatively connected and rotating with the spindle within the enclosure, the ingress feeding material into the sieve, the sieve sifting the fed material, and sifted material being fed from the sieve to the discharge;a conveyer operatively connected with the discharge, the conveyor having a generally cylindrical tube that extends from a first end at the discharge to an opposing terminal end, the tube having a tube diameter and an axis that extends through the first and terminal ends, the conveyor also having a helical blade rotatably mounted within the tube, the helical blade extending along the axis and between the first end and the opposing terminal end; anda blade drive operatively connected with and rotating the helical blade about the tube axis whereby a flow of air is generated through the tube, the sifted material is caught up in the flow of air, and the flow of air propels the sifted material through the conveyor.
