Screw Feeders – Precise Dosing of Dusty and Free-Flowing Products

In the process of packaging fine fraction raw materials, such as flour, dusts, or chemicals, the key challenge is to maintain cleanliness and weighing precision. In this category, we present professional screw feeders, which are an indispensable part of modern packaging lines. Thanks to the use of a screw conveyor (Archimedes' screw), these devices ensure a smooth and controlled flow of material, eliminating dusting issues and measurement inaccuracies.

Our screw feeders are advanced industrial units that integrate perfectly with weighing systems, creating complete solutions for food, chemical, and construction plants.

Applications of Screw Feeders in Industry

The specific design of the screw feeder makes it the best choice for products that tend to "hang up" in tanks or dust during free fall.

Main industries using screw feeders:

• Food industry: Precise packaging of flour, powdered sugar, ground coffee, milk powder, cocoa, and spice blends.
• Chemical and pharmaceutical industry: Dosing of dyes, powdered detergents, chemical additives, and bulk raw materials requiring sterility.
• Construction: Packaging of dusty materials, such as cement, gypsum, chalk, lime, and ready-mix building mortars.
• Agriculture: Dosing of fine feeds, vitamin concentrates, and artificial fertilizers.

Key Advantages of Technomaszbud Screw Feeders

By choosing our screw feeders, you invest in technology that combines mechanical durability with precise electronic control.

1. Unmatched dosing precision: The use of servomotors or precise electric motors allows for the exact determination of the number of feeder turns, which translates into repeatable dosing accurate to fractions of a percent.
2. Tightness and clean operation: The closed raw material transport system inside the dosing tube significantly reduces dust in the production hall, improving health and safety conditions as well as workplace hygiene.
3. High performance and automation: The devices can operate in automatic cycles, communicating with automatic packaging machines, allowing for the creation of fully autonomous workstations.
4. Ease of cleaning and maintenance: We design our machines for quick inspection. The possibility of easy disassembly of the screw allows for fast changeovers of dosed raw materials without the risk of contamination.

Types and Configurations of Feeders in Our Offer

We understand that every product has different physical characteristics. That's why we offer various feeder variants, which we tailor to your production's specifics:

• Feeders with an agitator in the tank: Prevent clumping and hanging of difficult raw materials (e.g., fatty or moist flour) above the dosing screw.
• Mobile feeders on a frame: Equipped with lockable wheels, allowing easy movement of the device between different production lines.
• Units with advanced PLC control: Allow programming of multiple recipes, smooth adjustment of rotational speed, and integration with higher-level plant systems.
• Feeders with varying capacities: From small laboratory units to powerful industrial feeders with large buffer tanks.

Why Is a Screw Feeder the Key to Optimization?

The introduction of automated screw dosing eliminates human errors and losses of valuable raw materials. Thanks to the stable operation of the device, the packaging process becomes predictable, and the final product – visually appealing and compliant with the declared package weight. At Technomaszbud, we deliver solutions that are durable, corrosion-resistant, and adapted for multi-shift operation.
