Micro Screw Conveyor

Introduction of Micro screw conveyor

Micro screw conveyors are ideal for micro-dosing applications, typically used in the production of chemicals and pharmaceuticals or any process that requires precise small quantities of additives. The diameter of the screw is 100mm-159mm, and the length (centre distance between import and export) is generally 100mm-2000mm. The conveying capacity is 0.01kg/h-1000kg/h, which is specially designed for small feeding speed and laboratory application.

Micro screw conveyors improve feeding accuracy by continuing to feed material into the outlet of the larger main screw feeder after the main feeder is closed, they are installed below the main screw feeder.

Function of Micro screw conveyor

The function of the micro screw conveyor is to precisely and accurately convey small quantities of material, usually ranging from a few grams to a few hundred grams. Here are some key features of the micro screw conveyor:

Metering and Batching: Can be used to deliver precise amounts of material to specific locations, ensuring the correct amount of material is used in the process.

Mixing: It can be equipped with mixing paddles or other devices to ensure that the materials are fully mixed before being conveyed to the next stage of the process.

Packaging: Can be designed to feed material directly to the packaging machine, ensuring that the package is filled with the correct amount of material.

Laboratory Applications: Typically used in a laboratory setting for handling small amounts of material. Screw conveyors can be used to convey material samples for testing and analysis, ensuring that the correct amount of material is used during testing.

The various types of micro screw conveyors produced by Dahan Company are available. If you have special needs, we will design them free of charge according to your actual situation.

Features and Benefits

1. The conveying capacity is between 3-22 cubic meters per hour, which is suitable for continuous feeding of small batches of powdery materials.

2. Small diameter and fast rotation speed can ensure uniform transportation of materials, and materials are not easy to be blocked. A loading and unloading gate can also be installed to control the flow of materials.

3. The whole conveying work is carried out in the pipeline, which avoids the pollution of dust to the environment and improves the working conditions at the same time.

4. The size is usually smaller than other types of conveyor systems, which makes them ideal for applications where space is limited. They can also be easily integrated into existing production lines.

5. Usually less expensive than other types of conveyor systems, especially for small applications. This makes them an economical choice for manufacturers who need to precisely transport small quantities of material.
