Screw Conveyors are one of the oldest and simplest devices used for the movement of bulk materials. Screw conveyors are compact and easily adapted to congested locations. They can be used as a mixer or agitator, to mix and blend dry or wet ingredients. Screw conveyors are available in a wide variety of materials to resist corrosion, abrasion or heat. Horizontal, inclined, or vertical conveyors are also available.
Multi Screw Conveyors
Multi Screw Conveyors are used as a screw feeder and may consist of twin, triple or quadruple screws, side by side. They provide a means of moving a wide variety of material from bins or hoppers at a constant and controlled rate of flow.
The inlet is usually flooded with material (100% loaded)
Volumetric metering device
Paddle Screw Conveyors
The Paddle Screw Conveyor is used when material needs to be mixed before reaching its destination. Adjustable paddles provide complete mixing action, and a controlled material flow. Conveying action can be controlled by adjusting the angle of the paddles.
Modular Plastic Screw Conveyors
Plastic modules consist of a helical flight spiraling once (360°) around a hollow square hub. The flight modules are available in polyethylene, polypropylene, and polyurethane, each with characteristics to fill specific needs. Theses modules are durable, corrosion proof and lightweight.
- FDA approved for food contact
- Can be replaced without welding or burning
- Assembled conveyor is comparatively lightweight, easier to handle, and bearing life is prolonged
- Slick surface simplifies cleaning
- Eliminates metal contamination in food
- Available in 6", 9" and 12" diameters, in right hand only
Vertical Screw Elevators
The Screw Elevator is ideally suited to elevate a wide range of bulk materials in a relatively small space. If a material can be classified as free flowing or very free flowing, it can probably be elevated in a Screw Elevator. We offer Standard and Superscrew Elevators with several different drive arrangements to meet your requirements.
- Transfer bulk materials vertically from one location to another
- Inlet must be control fed
- Typically used for free-flowing products
Shaftless Screw Conveyors
Shaftless Screw Conveyors are used in applications where particle sizes are large or the product is sticky or viscous. They do not require hanger bearings because there is no center pipe. Typical applications include wine and beverage industry, rendering, recycle plants, and waste water to name a few.
- Transfer sticky or viscous bulk materials from one location to another
- Design as conveyor or feeder
- Volumetric conveying or feeding device
Heat Transfer Screw Conveyors
Heat Transfer Screw Conveyors cool or heat bulk materials during conveying. These units may utilize special tubular jacketed housings or standard u-trough housings.
- Heat transfer mediums include water, glycol, steam, and hot oil
- Indirect heat transfer device
- Available only in: Hollow-flight design, Heat/cooled pipe only
Pressurized Screw Conveyor
Pressurized Screw Conveyor utilizes a tubular or pipe housing with ANSI flanges. This type of conveyor is used for conveying various types of materials and can be designed for various pressures and temperatures. ASME code stamp available on housings only.
Ribbon Screw Conveyors
Ribbon flight conveyor screws consist of sectional flights, buttwelded together to form a continuous helix. The flights are secured to the center pipe by supporting legs. They are used to convey sticky, gummy, or viscous substances, or where the material tends to adhere to the flighting and pipe.
Flex Screw Conveyors
Flexible screw conveyors are used to economically transport product over various distances, angles and rates. The conveyors are flexible, allowing a multitude of configurations to suit application requirements. 2, 3 and 4.5 inches with rates of up to 450 CFH are avaliable depending on the application. The standard unit consists of an inlet, discharge outlet, flexible spiral, casing, gearbox and motor. Two different styles of spirals are available: round and flat. The round is the most commonly used for its maximum strength and flexibility. The flat spiral is used for applications requiring higher throughputs.
