Micro Screw Feeder-DAHAN Vibration Machinery

Introduction of Micro Screw Feeder

The micro screw feeder is specially designed for small feed rates and laboratory applications. It can reliably and accurately feed a variety of powders and granular materials on a very small base, and feed accurately at speeds as low as 32g/h. With minimal residual material in the feeder, it is ideal for the production of chemicals and pharmaceuticals or any process that requires precise small quantities of additives.

Micro Screw Feeder

Micro screw feeder screw diameter is 100mm, 125mm, 139mm, the general feeding volume is from 0.01kg/hour to 1000kg/hour (please choose our other screw feeders for more than 1000kg/hour), the length of the feeder (in and out The distance from the center of the mouth) is generally 100mm-2000mm, which is specially used for uniform and continuous feeding and unloading of small batches of powdery and granular materials.

Application of Micro Screw Feeder

Application

Micro screw feeders have a wide range of applications in industries that require precise and accurate feeding of small quantities of materials. Here are some examples of industries and applications where micro screw feeders are commonly used:

1. Pharmaceuticals: Used to feed small amounts of active pharmaceutical ingredients (API) and other materials into tablet presses, capsule filling machines, and other pharmaceutical processing equipment.

2. Food processing: It is used to feed a small amount of flavoring, coloring and other additives into food processing equipment.

3. Electronics manufacturing: Used to feed small quantities of solder paste, flux, and other materials into automated soldering equipment.

4. Chemical processing: Used to feed small quantities of catalysts, additives, and other materials into chemical reactors and other processing equipment.

5. Laboratory research: Used in laboratory research to dispense small quantities of powders and other materials for experiments and testing.

Benefits of Micro Screw Feeder

Small feeding amount

The screw diameter is 114-159mm, and the feed rate is as low as 32 g/h, and the feeding rate is from 0.01 kg/h to 1000 kg/h.

High feeding accuracy

Minimum clearance between propeller and feed tube ensures high precision feeding, Accuracy: 0.1 kg (up to 0.01 kg with special screws).

Small footprint

Accurately feed a wide range of powders or granules in a very small footprint, ideal for laboratory applications.

Sealing system

The whole conveying work is carried out by bucket type in the pipeline, which avoids the pollution of dust to the environment.

Uniform delivery, not easy to jam

Small diameter screw, and low rotation speed, ensure fast and even product delivery.

Flexible layout

The inlet and outlet can be made into the required inclination angle according to the situation of the work site, and it can be connected and fixed with other supporting equipment.

Available Options

Micro screw feeders can be customized with a variety of options to meet the specific needs of different applications. Here are some common options available for micro screw feeders:

1. Hopper: A hopper can be installed to increase the capacity and provide buffer for the fed material.

2. Material level sensor: A material level sensor can be installed to monitor the amount of material in the feeder and adjust the screw speed accordingly.

3. Discharge valve: a discharge valve can be installed to control the material flow and prevent overfeeding or underfeeding.

4. Agitator: Agitator can be added to prevent material bridging or blockage.

5. Hoses: hoses can be added for easy connection to other processing equipment.

6. Special coatings or materials: Can be coated with or made of specific materials to handle corrosive or abrasive materials.
