Abstract
An inlet device comprises an inlet chute, an inlet hopper pan and two agitator blades in counter rotation above the flights of a plug screw feeder. The blades are housed in a pan which sealingly connects to a cast plug screw liner which is a U-shaped trough for the plug screw. The agitator blades are driven by shafts supported in pillow block bearings fastened to a main housing. The main housing holds a gear train driven by a right angle gearmotor. The gearmotor is also mounted on the main housing and drives abutting geats in counter rotation above the flights of the plug screw. A storage bin, reservoir, worm conveyor or some type of pulsating feeding arrangement feeds directly into the instant inlet device. The inlet device then feeds into line operations, e.g., a pulp refiner line operation.
