In many industries, including chemicals, batteries, and ceramics, uniformly mixing powders and liquids into slurries is a critical and challenging step. Agglomeration and uneven mixing have long plagued production. The Trough Mixer, with its flexible design and strong adaptability, has become a key piece of equipment for solving these challenges.
Coreal Machinery has compiled some information for your reference.
I. Typical Problems of Powder Slurry Mixing
1. Powder Agglomeration: Micron- and nano-sized fine powders have high surface energy, easily adsorbing and forming clumps that are difficult to disperse.
2. Uneven Wetting: When powder is poured into a liquid, if it is not quickly coated, it can easily form a "floating powder" or "dry powder layer" on the liquid surface, making it difficult to wet.
3. Sedimentation and Stratification: Dense, coarse-grained powders tend to settle to the bottom of the tank when mixing stops or when stirring is insufficient, forming a hard sediment, resulting in uneven slurry concentration.
4. Shear Sensitivity and Equipment Wear: Some slurry active ingredients or particles are sensitive to high shear forces. Furthermore, high-hardness powders can severely wear mixing equipment.
5. Difficulty in Degassing: Air can easily be entrained during mixing, forming bubbles, which can affect the density and performance of the final product.
II. Advantages of the Trough Mixer
1. High Flexibility: The mixer's type, speed, power, and material can be customized based on material characteristics and process requirements, offering a wide range of applicability.
2. Excellent Mixing Performance: The combination of "volume circulation + high shear" achieves both macro-uniformity and micro-dispersion, resulting in stable and reliable mixing quality.
3. High Functional Integration: The mixer integrates functions such as feeding, mixing, dispersing, heating/cooling, and vacuum degassing, achieving multi-functionality in one machine.
4. Easy Operation and Maintenance: The device's relatively simple structure facilitates cleaning, material changes, and routine maintenance.
III. Typical Application Scenarios
1. New Energy Battery Industry: Core applications include electrode slurry preparation, which requires extremely high consistency and bubble-free requirements.
2. Electronic Ceramics Industry: Suitable for uniformly mixing electronic ceramic slurries such as alumina and aluminum nitride. The quality of mixing directly impacts the performance of the sintered product.
3. High-End Coatings/Ink Industry: Used for dispersing nano-pigments and fillers, requiring extremely fine particle size and uniform distribution.
4. Pharmaceutical and Food Industry: Suitable for mixing and homogenizing paste-like and pasty materials.
