ABSTRACT:
The present invention provides a method and apparatus for conveying very fine material, for example, a material where 100 percent of the material is less than fifty microns in diameter, and 50 percent of the material is less than five microns in diameter. The method utilizes a vibratory conveyor, on the surface of which is formed a bed of relatively large particulate material (50 mesh or larger in diameter, for example), and the very fine particles are introduced onto the bed. Under vibratory conveying motion, the fine material filters into the interstices formed by the larger particles and thus the fine material is conveyed along with the coarser material to a point of delivery. Another aspect of the invention includes the step of separating the fine material from the particulate material and recirculating the latter. Also, the recirculating particulate material may be chilled during recirculation and thus acts as a cooling agent when reintroduced to the conveyor.
