(28) Body The Metric feeder is ruggedly constructed to maintain roundness. It can be furnished with either a closed or open end rotor. The throat inlet is angled to induce a shearing action for smoother operation. An optional port is available and extends the full length of the body. It may be used as an inspection panel and clean-out port. The inlet flange easily adapts to a square or a standard 125 Ib. ASA flange on Models 150, 300, 700, 2500.
Rotor Two basic designs are available - open or closed end. All rotors have eight (8) vanes with a minimum of four (4) vanes sealing at all times to minimize leakage. Rotors can be furnished with beveled blades and hard-coated tips as required.
(3) General The DA Feeder introduces material into the conveying system at highest volumetric efficiency when material flow into the feeder is controlled to permit free venting. The feeder may be used under a head of material when appropriate aeration is provided to create a path for relief of the reverse air flow. In operation, air enters a single inlet and passes into the rotor pocket through two (2) ducts integrally cast in the end plates, assuring complete fluidization and discharge. High efficiency is attained through the combination of gravity and air-sweeping of the fluidized material into the conveying line. This design principle assists greatly in discharging materials which have a tendency of hanging up in the rotor ...
(28) General 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 ...
(12) General FLSmidth manufactures three (3) types of “P” feeders with closed end rotors: Type I Body end plates constructed of #50 cast iron with fabricated stainless steel rotor. Type II Body and rotor constructed of type 304 stainless steel with aluminum end plates. Type III Complete 304 stainless steel (body, rotor and end plates).
Body and End Plates The body and end plates have heavy-duty construction and permit minimum rotor clearances. Motor support lugs are cast as an integral part of the 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 ...
