Abstract
The production capacity of a conventional high pressure feeder having a pocketed rotor with a slotted screen at the low pressure outlet port is significantly increased by constructing the screen so that its arcuate bars have a width much less than normal, and thus a much greater open area of the screen is provided. Structural integrity is maintained by providing a reinforcing bar extending transverse to the arcuate screen bars, typically attached at the convex mid-point area. The screen is formed from a cast metal body, and the width of the arcuate screen bars is typically between about 0.14-0.20 inches.
