Howell Ful-Flo Drag Conveyors
Drag Conveyor sizes range from 8”-32” wide x 10”-30” high. Howell guarantees capacity with the least amount of product damage with minimal maintenance. Ful-Flo Drag Conveyors are available in painted mild steel, stainless steel, and galvanized.
Series I Drag Conveyors
Series I Drag conveyors come in 10”, 14”, and 18” heights and 8”, 12”, 16”, 20”, 24”, 30”, and 32” widths. Series I Conveyors use 81X or 81XH chain depending on the size. All Series I Conveyors will have 1½” flanges. Series I Conveyors range from 500-20,000 BPH.
Series I Head Section
Series I Head Sections are constructed with 7 ga. material. They can have either flange or pillow block bearings, and use a keyed shaft and sprocket. They also feature a slack chain device, and plug switch. The Head section may have 8” take-ups if there is no room for them on the tail section.
Series I Trough Section
Series I Trough Sections are available with 7 ga., 1/4”, or 3/8” Abrasive Resistant steel bottom, or UHMW plastic lined mild steel 10 ga. bottom. Side liners include 10 ga., 7 ga., or ¼” Abrasive Resistant Steel or UHMW plastic. Howell conveyors use return rail with UHMW plastic on which the chain returns to head, wider conveyors will also use tip rails to prevent the chain from twisting during conveying.
Series I Detector Tail Section
Series I Detector Tail Sections are constructed with 10 ga. material, and use flange bearings. Detector Tails utilize compression spring at the ends of the take ups to automatically take out slack from the chain during operation. This eliminates the need to manually tension the chain. This automatic style of take up also utilizes a shut off switch so that if the conveyor gets jammed or plugged it will immediately shut down the conveyor, preventing extensive damage. The same is true if the chain becomes too loose. If there is a clearance issue a standard tail must be used.
*Detector Tails are only available on conveyors with an incline less than 15 degrees*
Series I Tail Section
Series I Tail Sections are constructed with 10 ga. material. They can have either flange or roller pillow block bearings. Tails will have 8” take-ups for tensioning. If there is a clearance issue they can be mounted on the head or reversed upon customer request. In this case the tail becomes an idler box. In some cases the tail may have the drive.
Series II Tail
Section Series II Tail Sections are constructed with 10 ga. or 7 ga. material. They can have either flange or pillow block bearings. Tails will have 8” take-ups for tensioning. If there is a clearance issue they can be mounted on the head or reversed upon customer request. In this case the tail becomes an idler box. In some cases the tail will have the drive.
DRAG CONVEYOR ACCESSORIES
Discharge transitions are made from 10 ga. material and can be made to go from the head or intermediate discharge flange down to any desired size square or round. Transitions can be lined with Abrasion Resistant Steel, Ceramic, or Urethane.
Head Shut-off Gate
Head shut-off gates are made of 10 ga. material and can be manually operated with the use of a cable, chain or hand wheel, or they can be electrically operated.
Intermediate Discharge Gate
Intermediate discharge gates are made of 10 ga. material and can be manually operated with the use of a cable, chain or hand wheel, or they can be electrically operated.
Knee Bend Section
Knee bend sections are designed to incline a drag conveyor after it runs horizontal. This is to get the desired discharge height without inclining the entire conveyor. They can incline 5-45 degrees depending on what is needed. They are constructed from the same material as the trough.
Bypass inlets can be a variety of different sizes. They are available with grating for use as a dump pit, or with a companion flange. The purpose of the bypass inlet is to direct the product around the returning chain with the use of a hogback, and enter the conveyor through the sides. This allows the conveyor to be flood fed without plugging because the bypass inlet only allows what the conveyor can handle. This is ideal for truck or rail receiving pits, or for reclaiming storage bins.
Standard inlets are field installed where product is to enter the conveyor. They include a hogback to divert the product over the chain and return rail.
Combo Inlet Gate
Combo inlet gates are much like a standard inlet, except they have a door that can be closed to shut-off product flow into the conveyor. These can be manually operated with the use of a cable, chain or hand wheel, or they can be electrically operated.
Ladder Inlet Gate
Ladder inlet gates allow controlled flow of product into a conveyor which allows the conveyor to be flood fed. These can be manually operated with the use of a cable, chain or hand wheel, or they can be electrically operated.
Heat Sensors and Speed Monitors
Upon customer request bearing heat sensors and shaft speed sensors can be installed.
