The structural principle and wide application of slot mixer
Date: 2025-09-24Read: 46
The trough mixer is a dry powder or paste material mixing equipment widely used in industries such as pharmaceuticals, food, and chemicals. Its core structure and working principle are as follows:
1、 Structural composition
1. Mixing tank: It adopts a horizontal groove design, usually made of all stainless steel material, and can be flipped 360 degrees to achieve material pouring function.
2. Mixing device: equipped with S-shaped or screw type mixing blades, horizontally installed in the tank, and driven by rotation to move the material axially.
3. Transmission system: including motor, reducer and sealing device, ensuring that the mixing blade operates at a constant speed (such as 24 revolutions per minute).
4. Control system: supports mixed time setting and automatic shutdown, and some models are equipped with jog buttons to control the discharge angle.
2、 Working principle
By rotating the stirring blade, the material forms a spiral axial flow in the groove, while the surrounding materials fill the gaps towards the center, achieving up and down flipping and mixing. For materials with large differences in specific gravity, some models use a five axis flying knife structure to enhance dispersion and avoid layering or dead corners.
3、 Application Fields
1. Pharmaceutical industry: used for uniform mixing of drug powders, in compliance with GMP standards.
2. Food industry: Processing dry powder or wet raw materials, such as seasonings, additives, etc.
3. Chemical and Electronic: Mixing powders or paste materials with high uniformity requirements.
4、 Technical advantages
1. Efficient mixing: The loading rate can reach 90%, and the mixing time is short.
2. Wide adaptability: Supports materials with different densities and viscosities, with high mixing rates.
3. Easy to operate: compact structure, easy to clean, some models support automatic cleaning.
Note: In actual use, attention should be paid to load adjustment and component maintenance to avoid problems such as difficult startup or host vibration.
