At METALFAB, customers are the cornerstone of our business. Since 1977 when we started our operations, we have engineered the highest quality dry solids processing equipment to meet our customers' needs.
Originally focused on developing the industry's leading Bin Activators, Metalfab today manufactures a full array of additional low-maintenance products including volumetric screw and belt feeders, Better-Weigh¨ batch and continuous loss-of-weight feeders, bulk bag unloaders, continuous blenders and spin loaders, Convey-All/Flexible Screw Conveyors and Convey-All/Vibratory Tube Conveyors.
All DB1 models incorporate a compound screw arrangement called agitator/conditioner screws. The action of these screws influence the movement of material in a full 360 degree radius (not just the sides or the bottom) insuring that the flights of the metering screw are filled to their maximum capacity with uniformly dense material.
Volumetric Screw Feeder DB1
Volumetric Screw Feeder
Metalfab DB1 is a simple, low-cost, ruggedly-built feeder that provides extremely accurate, dependable metering of a wide range of dry particulate materials.
Virtually maintenance-free, the Model DB1 has only 5 moving parts: drive, coupling, screw and two bearings. An agitator / conditioner screw, available in all but 6" units, fills the feed screw completely, resulting in feed accuracies of +/- 1 to 1 1/2% (based on one minute samples).
All feed screws are made with through shafts to eliminate breakage. These shafts are supported by oversized ball bearings, which are sealed and provided with grease fittings. All standard units (1" to 6" screw sizes) have feed rates from 0.25 to 550 cu. ft./hr. A 5 cu. ft. hopper, with 70 degrees sloped sides and large rectangular outlet, provides capacity for most surge conditions. If desired, the hopper can be removed and replaced with up to a 10" diameter inlet trough cover. The unit can then be preceded by a Metalfab Bin Activator or Posibin.
Interchangeable screw and tube combinations permit feed rates beyond the 20:1 range of variable speed drive.
The cost of a basic unit complete with motor and drive control is $3,500.00
Sanitary Screw Feeder DB1S
Sanitary Screw Feeder
The Metalfab model DB1S sanitary feeder offers the simplicity of the standard DB1 unit, while satisfying the most stringent sanitary processing requirements necessary for the metering of such critical materials as pharmaceuticals and foodstuffs. All contact surfaces are of 304 or 316 stainless steel and polished to a #4 finish. All welds are continuous and ground smooth to prevent product build-up and adherence. Gasketing is food grade white neoprene and a rear seal with Teflon packing gland is standard. All external carbon steel parts are painted with white epoxy paint.
Extra clearances are provided beneath the unit for ease of cleaning, but should it become necessary, the DB1S can be disassembled for cleaning without the use of tools. Screw sizes range from 1" to 6", with agitator/conditioner screws on all but the 6" size. The D.C. motor is TENV (suitable for wash down). Can be made to comply with 3A dairy standards.
The cost of a basic unit with motor and drive control is $6,400.00
Space Saving Screw Feeder DB1C
Space Saving Screw Feeder
DB1C series compact volumetric screw feeders offer the same high quality construction features and precision performance as Metalfab's standard-size feeders, plus a unique space saving benefit. Due to the positioning of their DC drive which has been placed alongside the feeder trough and parallel to it, the compact, new DB1C units require less than 3 1/2 sq. ft. of space, half the space of most conventional feeders.
Virtually maintenance-free, DB1C series compact volumetric feeders have only 5 moving parts: drive train, timing belt, screw, and front and rear bearings. The heavy duty timing belt transmits power from the DC drive to an agitator/conditioner screw which fills the feed screw completely, providing feed accuracies of +/- 1 to 1 1/2% based on one minute samples.
A 5 cu. ft. hopper with 70 degree sloped sides and large rectangular outlet, provides capacity for most surge conditions. The hopper is removable and can be replaced with up to a 10" diameter inlet trough cover. The unit can then be preceded by a Metalfab Bin Activator or Posibin.
The cost of a basic unit with motor and drive control is $3,600.00
"Mini Feeders" DB1M
"Mini Feeders"
Designed for applications where space is critical, Metalfab Model DB1M mini feeders provide dependable, highly accurate feeding of a wide variety of dry solid materials from an extremely small base of only 12" x 16". A 1 cu. ft. hopper with sharply sloped sides and large rectangular outlet, provides capacity for most surge conditions. The hopper is removable and can be replaced with up to a 6" diameter inlet trough cover. The unit can then be preceded by a Metalfab Bin Activator or Posibin.
The cost of a basic unit with motor and drive control is $3,200.00
Volumetric Screw Feeder DB1T
Volumetric Screw Feeder
The model DB1T feeder provides all of the features available with the standard Metalfab DB1, but is designed for the handling of more difficult feed materials such as film scrap, wood chips, filter cake, fibrous products and many other materials which present vexing problems in attempting to fill the flights of the metering screw.
To solve these problems, the DB1T has been designed with greater clearances and larger agitator / conditioner screws (including one for the 6" size) and the downspout at the discharge end has been eliminated.
Standard metering screws are 3", 4", and 6"
The cost of a basic unit with motor and drive control is $4,300.00
Combination Screw Feeder/Conveyor DB2
Combination Screw Feeder/Conveyor
A highly accurate, dependable volumetric screw feeder, Metalfab Model DB2 has only five moving parts - drive, coupling, 2 bearings and a screw. It is designed for the precision metering of dry materials in the chemical, food, plastics, pharmaceutical and foundry industries, but may also be used successfully as a short distance conveyor, with center of inlet to outlet dimensions of 3' to 12'.
The large diameter inlet to the V-shaped trough, which helps insure complete filling of screw flights provides feed accuracies of +/- 1 to 1 1/2%. When a Metalfab Posibin or Bin Activator is used to supply the feeder, even greater accuracies may be obtained.
A bin activator is recommended when feed rates are more than 1,000 cu. ft./hr. or non-free flowing materials are in process.
Flight-type screws with through shafts are standard. Oversize ball bearings which are sealed and provided with grease fittings support the shaft.
Operating noise levels are within OSHA requirements. All moving parts are guarded and the screw section is totally enclosed.
The cost of a basic unit with motor and drive control is $5,500.00
