Twin Screw Feeder

Twin screw feeder is designed to provide accurate feeding for problematic and poor flowing powders materials such as pigment, sticky, lumpy, moist, bridging or flooding powders, fiber, flake, fiberglass, and so on.
TiERMAX twin screw feeders are available with a variety of interchangeable feed screws depending on the material being fed.

We supply twin screw feeder with both volumetric and gravimetric configuration and with exchangeable screw design.Twin screw feeders are widely used in a variety of industries, including construction, chemical, food, beverage and others.

All contact material parts are stainless steel. The feeder is easily disassembled for cleaning or change over.
The feeder is easily disassembled for cleaning or change over.
The twin screw feeder may be equipped with a dispersing agitator or lump breaker to consistently fill the screw and prevent hopper bridging.

Twin screw feeder technology:

Tiermax’s provide twin screw feeder with both volumetric and gravimetric configuration for continuous and batch process.

A twin screw feeder can be used to feed a wide range of problematic and poor flowing powders, such as pigment, sticky, lumpy, moist, bridging or flooding powders, fiber, flake, fiberglass, and so on, with high precision.

The TiERMAX twin screw feeder comes with a variety of feed screws that can be changed depending on the type of material being fed.

Volumetric screw feeders:

These volumetric feeders are ideal for dosing free flowing raw materials in batches or continuously. Agitators, that are optional, ensure free-flowing powders and a smooth process of conveying, dosing, and/or mixing via dosing screw feeder systems.

Volumetric screw feeder is a simple and effective equipment for dosing dry material that is also fast and easy to operate. The moisture content, flow properties, particle size, and bulk density of the product, all have an impact on how well the screw fills.

Volumetric screw feeder operation:

The volumetric feeding principle begins with retaining the auger full and on the other side, a volumetric screw feeder does this based on volume in speed. The size, pitch, and rotational speed of the screw (auger) are the main parameters in volume displacement. A volumetric screw feeder transfers a specific amount of material to a process in a given amount of time.

These volumetric screw feeders are consisting of a controller, a hopper made of 304 or 316 stainless steel, a customized screw design, gearmotor, and a base plate.

Bulk material is stored in a screw feeder hopper and is continuously fed into a process using a variable screw speed. Screws are designed to achieve the desired feed rate based on the specification of the feeding material and its bulk density.

The required flow rate of material can be controlled by the controller. Single screw feeders (sometimes referred to as single screw volumetric feeders) are utilized in a wide variety of industries where dry free-flowing powders, granules, crystals, or pellets are used.

Gravimetric screw feeders:

A single screw loss-in-weight feeder can be used to accurately feed a wide range of materials, such as pellets, granules, free-flowing powders, and other bulk materials. This gravimetric single screw feeder is available with a range of replaceable feed screws to handle a variety of different materials. It adopts high-speed, highly precise load cells. The scale is constructed entirely of 304 stainless steel, as is the housing.

This gravimetric single screw feeder is easily disassembled for cleaning and changing. The gravimetric screw feeder may be equipped with a dispersing agitator or lump breaker to consistently fill the screw and prevent hopper bridging.

Gravimetric screw feeder operation:

By recording and measuring the materials used, a gravimetric screw feeder is a self-calibrating dosing system that doses based on the weight in a fast and efficient manner.

Our gravimetric screw feeder is equipped with three-point suspension scales and a self-detection function for more accuracy. It allows attritions of parts and frequency variation timely then revise them so the gravimetric screw feeder will not affect feeding precision.
