The demand for accurate flexible wall feeders:
Most manufacturers are facing challenges with accurate dosing and increasing the number of ingredients in their production process. Screw feeders are designed to meter bulk materials at a controlled feed rate and are utilized in thousands of material handling applications.
The failure in metering and not accurate dosing will put the production process at risk.
Our flexible wall feeders are highly adaptable machines that can be used to handle volumetric and gravimetric dosing for a wide variety of materials.
Whether it’s powder, grains, cakes, fine, dusty, chips, pills, or frozen chunks of fruit, TiERMAX has a feeder that can properly administer them.
TiERMAX Flexible wall scew feeder:
Tiermax feeders have included Flexible Wall Hopper, which is a wall hopper with a flexible exterior. The flexible wall hopper mechanically and evenly massaged by paddles and dry material continuously keep in motion and transport smoothly.
As the paddles are not inside the wall hopper, the dry material will not be damaged, and ratholing, bridging, or clogging will be avoided.
TiERMAX flexible wall feeder is designed to provide accurate dosing for problematic and poor flowing powders materials such as flavor, spice, bridging or flooding powders, and so on.
A flexible wall feeder for wide application:
There is an appropriate Flexible Wall feeder with the proper specs for every dry material dosage.
Cleaning expenses are reduced due to the easily removable and interchangeable hopper, for example, in the event of colour changes or pigments.
The expansion hopper’s feature allows the TiERMAX flexible wall feeder to expand the size of the hopper up to 1000 liters.
High quality flexible hopper designed for challenging production process such as high temperatures, acid-resistant, food-safe (FDA) , and anti-static.
Loss-in-weight Screw feeder:
A flexible wall 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 flexible wall 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.
Volumetric screw feeders:
These volumetric flexible wall 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 flexible wall screw feeder is 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.
Frequently Asked Questions
A Flexible Wall Feeder is a feeding system designed to accurately discharge and meter difficult powders and bulk materials using a flexible hopper and screw feeder.
A volumetric Flexible Wall Feeder controls feed by screw speed, while a gravimetric Flexible Wall Feeder uses load cells to maintain a precise feed rate by weight.
The flexible hopper continuously flexes during operation, preventing bridging and rat-holing while ensuring a smooth, consistent material flow.
Flexible Wall Feeders are suitable for cohesive powders, flakes, fibers, granules, lightweight materials, and other difficult-to-flow bulk solids.
A gravimetric model is ideal when high dosing accuracy is required or when material bulk density changes during production.
It improves material flow, reduces product buildup, minimizes segregation, and provides reliable, accurate feeding.
They are widely used in the food, chemical, pharmaceutical, plastics, battery, and mineral processing industries.
Select a feeder based on material characteristics, required feed rate, hopper capacity, feeding accuracy, and process requirements.
Regular maintenance includes cleaning the hopper, inspecting the flexible wall and screw, and checking the drive and weighing system.
Yes. Flexible Wall Feeders can be customized with different hopper sizes, screw designs, construction materials, sanitary finishes, and control systems for specific applications.
