Can a granule filling machine handle powders?

Granule filling machines are generally not suitable for directly processing powder materials, but in some cases, they can be partially compatible with lightly flowable fine granules or coarse powders through structural optimization. The following is a breakdown explanation:

1. The design of granule filling machine is mainly aimed at solid granules
Explanation: The feeding, metering, and discharging structure of the granule filling machine is designed specifically for uniformly sized and well flowing granular materials such as candies, pills, coffee beans, etc.
Impact: Powder is prone to flying, clogging, and moisture absorption, making it difficult for granule filling machines to accurately process.

2. Powder is prone to flying and pollutes the environment
Explanation: Powder is prone to dust during filling, and without dust prevention measures, it can contaminate equipment and workshop environment.
Impact: granule filling machines are usually not equipped with specialized dust removal devices or sealed filling chambers, making them unsuitable for handling fine powder materials.

3. Powder is prone to clogging the feeding mechanism
Explanation: granule filling machines often use vibrating slots, spiral feeders, or measuring cups for feeding, which are not suitable for handling viscous or extremely fine powders.
Impact: Powder may adhere to the surface of components, causing poor feeding and even shutdown.

4. Difficulty in ensuring filling accuracy
Explanation: Powder flowability is much lower than that of granules, and it cannot flow uniformly through gravity or vibration, especially for fine powders or irregular granules.
Impact: It is prone to measurement errors of "over filling and under filling", which is not suitable for products that require high filling accuracy.

5. If it is coarse powder, it is conditionally compatible
Explanation: Some granule filling machines can handle coarse powders or granular mixtures with larger granule sizes (such as coarse sugar, granular seasonings, granular fertilizers, etc.).
Requirement: Auxiliary functions such as dust cover, low-speed screw, and sealed discharge port should be equipped to avoid powder flying and residue.

6. Special powder filling machines should be selected for powder processing
Recommended equipment: Powder filling machine (such as screw powder filling machine)
Equipped with a closed structure and dust removal system;
Adopting a screw metering system, specifically suitable for powders with poor fluidity;
High filling accuracy, suitable for materials such as milk powder, flour, seasoning powder, medicinal powder, etc.

7. Some granule filling machines can be modified to compatible models
Explanation: The granule filling machine can be adapted to a certain range of powdered materials by replacing the feeding mechanism, adding a sealing system, or modifying the measuring method.
Applicable situation: For granule+powder mixed packaging or budget limited scenarios, compatible design can be considered.
