FLSmidth Feeder TE Rotary (Airlock)

When installed in a pressure conveying system, the use of (optional) Lantern Rings and (standard) Air Purge is recommended when fine powdery material is being conveyed to prevent contamination of packing and bearing. The air purge should be set 2 to 4 PSIG (.14 to .28 Kg/cm2) above conveying line pressure. Body and End Plates The body and end plates are heavily ribbed and constructed of #50 cast iron. Motor support lugs are cast as an integral part of body and permit the mounting of the gearmotor directly on the unit, resulting in a compact package. The end plates have integral cast outboard bearing supports and male-female joints between end plates and feeder body ensuring concentricity. Rotor All rotors are constructed of machine #50 cast iron and have six or eight vanes with four vanes in seal between inlet and outlet except for the 2" totally enclosed feeder (airlock) which has four vanes. The rotor shaft has a tapered hub to reduce friction from trapped material between rotor and end plates. Anti-friction bearings are shielded, and mounted on rotor shaft outboard of the packing gland. Beveling of the rotor vane is recommended if the material has a tendency to build up and smear. Motor Mounts All gearmotors are mounted directly to feeder body except the 2" and 5" (50 mm and 125 mm) TE Feeders which incorporate a single common steel base plate. Motor Drive All fractional gearmotors are TENV. All integral horsepower gearmotors are TEFC. All gearmotors are 3 phase, 230/460 Volts, 60 Hz. Special Notes All standard feeders (airlocks) are designed to handle material having a maximum temperature of 150° F (65° C). Above 150° F (65° C requires additional periphery and end clearances. From 700° F to 900° F (371° C to 482° C) requires additional clearance and water cooled shaft. Above 900° F (482° C) and not in excess 1200° F (650° C) requires ductile iron construction, special bearings and water cooled rotor.
