Screw conveyer system

摘要

A system for treating a material includes first and second screw conveyors each having a rotary shaft and a helical flight extending radially outward therefrom, the flighting of the screw conveyors overlapping with each other, and first and second actuators operably coupled to the first and second screw conveyors in a one-to-one dedicated relationship to rotationally drive the screw conveyors independently of each other. In typical embodiments, also included is a system for varying the clocking position of the screw conveyors relative to each other, wherein the screw conveyor flights are axially adjusted with respect to each other between a normal position and an advanced and/or retarded position. Also disclosed are methods of varying the axial position of the screw conveyor flights with respect to each other between the normal and advanced and/or retarded positions.

1. A system for treating a material, comprising:
a first screw conveyor comprising a first rotary shaft and a first helical flight extending radially outward from the first rotary shaft; a second screw conveyor comprising a second rotary shaft and a second helical flight extending radially outward from the second rotary shaft, the first helical flight and the second helical flight overlapping; a first actuator operably coupled to the first screw conveyor; and a second actuator operably coupled to the second screw conveyor.
