(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 ...

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 ...
(8) General The FLSmidth Shrouded Suction Airlock uses a rotor with closed vane pockets which keeps material from contacting the end plates. This valve is primarily designed to release material at relatively fixed rates for dust collector applications. Handles materials up to 400°F (205°C). Maximum temperature surrounding motor 104°F (40°C). Higher temperature options at additional cost. Available with or without motor drive. Pressure differential up to 30" W.G.
Body All #50 cast iron construction machined for close tolerances.
Rotor Fabricated steel with closed ends. Four pockets. optional, Standard or Beveled rotor vanes. This valve is equipped with shielded anti-friction bearings. End ...
The FLSmidth slide gate is a simple, economical, easy-to-install discharge valve commonly used dust collection equipment when only periodic clean-out is required.
General The FLSmidth Swing Gate is a manually operated, self-locking discharge valve. in an open position it presents minimum obstruction to dust discharge flow. This gate features a post-center toggle locking device.
Body The body is a single, cast iron unit that is designed to create an airtight seal with the swing-gate seal.
Gate The Swing Gate is mechanically tensioned against the body valve seat using a gasket. Rubber gasket permits use up to 250° F (121° C). Special silicone seal gasket extends operating range up to 400° F (205° C).
(7) General The FLSmidth Two-Gate Valve provides a dual-gate airlock seal against a differential pressure up to 17” W.G. and will withstand material temperatures up to 400°F (205°C). For material temperatures to 700°F (371°C). special motors and heat shields can be provided at extra cost.
Body The valve body is constructed of seven (7) gauge fabricated steel plate. Inspection plate cover permits easy service access.
Gates The FLSmidth Two-Gate Valve has two (2) sealing gates which alternately open and closes as material passes through the unit in order to maintain a seal between material inlet and outlet. The alternating cycle is mechanically operated using an eccentric and gear ...
(8) General The FLSmidth Trickle Valve is an adjustable, counter-weight discharge valve which automatically responds to flap gate imbalance by releasing collected material. Good for applications up to 400° F (205° C).
Body The body is durable twelve (12) gauge steel plate construction. Simple design presents minimum material restriction.
Gate Constructed of steel plate, the flap gate is gravity-operated with an adjustable counterweight. The flap gate is mounted on a finished shaft and rotates freely on outboard, self-aligning ball bearings.
(7) General The FLSmidth Type SK One-Way Cutoff Valve is available in six basic sizes. The 3 through 6-inch (75 -150 mm) valves match the I.D. of standard Schedule 40 pipe. The 8 and 10-inch (200 and 250 mm) valves match the I.D. of standard Schedule 30 pipe. Operating temperature up to 400° F (205° C).
Body Durable machined cast iron construction.
Disc The valves employ replaceable hardened seats and discs, ground and lapped to ensure positive sealing. Air cylinder actuator provides fast and positive cutoff operation. 50 to 100 PSlG (3.5 to 7 Kg/cm2) clean plant air required.
Accessories Weather-proof (NEMA 4) limit switches are included for positive ...
(13) FLSmidth is proud to offer a new line of high quality butterfly valves to meet the requirements of today's market. Combining years of field application experience in the minerals and cement markets, with research and development, FLSmidth has designed many unique features into the valve, resulting in longer service life, greater reliability, ease of parts replacement and interchangeability of components.
(4) For Flow Control Of Pulverized Materials Flow control gates provide an accurate means of flow control and positive shut-off of pulverized material from storage silos and feed bins. Four different sizes provide a range of control from complete shut-off up to 20000 ft3/hour! Units are available for electric or air operation.
Basic Valve Housing is cast aluminum with machined integral actuator brackets and mounting flanges drilled to match FLSmidth Airslide dimensions.
