Two-chamber mill for treatment of damp or wet crops - has passage of adjustable size between first and second chambers

摘要

The material to be treated (e.g., partially ripe maize) is fed in through an opening at the bottom of the first chamber, from which it passes, reduced in size, through a gap in a dividing wall into the second mill chamber, round which it passes just once before leaving the mill. By the invention, the strikers which reduce the grist swing freely on axles; the passage between the two chambers is at the highest point of the dividing wall, is adjustable in size (possibly by turning the circular partition), occurs where there is an outward bulge in the circumference of the first chamber, and is set immediately downstream of the final exit nozzle, from which an angle plate separates it.
