How to choose a horizontal screw belt mixer for dry powder feed mixer

Scope of application of dry powder horizontal screw belt mixer

Applied to the mixing of solid (i.e. powder to powder) and slurry (i.e. powder to slurry) in pesticides, veterinary drugs, food, chemicals, biology, aquaculture, ceramics, refractory materials, plastics, compound fertilizers, etc., it is particularly suitable for mixing viscous materials.

The screw belt mixer, with its efficient mixing performance and wide adaptability, has been deeply applied in multiple industrial fields, especially in industries with high requirements for mixing uniformity, production efficiency, and hygiene standards.

1、 Main application industries and typical scenarios

Chemical industry

Spiral belt mixer is widely used for mixing materials such as catalysts, coating materials, dyes, adhesives, etc. Its double-layer spiral structure can effectively prevent local concentration deviation and ensure uniform composition of reaction materials. For high viscosity materials (such as dry mixtures of carbon powder and resin with viscosity ≤ 50000cP), the equipment can still achieve efficient mixing. Some models use 316L stainless steel structure, which has strong corrosion resistance and is suitable for strong acidic and alkaline environments.

Food and Beverage Industry

In food processing, a ribbon mixer is used to evenly mix flour, seasonings, meal replacement powders, vitamin additives, and other powders with liquids. The equipment meets the requirements of food grade materials (such as 304 stainless steel), supports jacket temperature control, and can accurately control the temperature of chocolate slurry within ± 0.5 ℃ to ensure product quality. Designed to be easy to clean and meet HACCP and GMP hygiene standards.

In the field of pharmaceuticals and health products

Used for high-precision proportioning and mixing of traditional Chinese medicine powders, Western medicine excipients, and tablet raw materials, with a mixing accuracy of ± 1%, ensuring drug consistency and effectiveness. The equipment complies with GMP cleanliness standards, supports aseptic operations, and is suitable for handling sensitive materials such as antibiotics and vaccine excipients. The intelligent sensing system can monitor the mixed process parameters in real time, improving the stability of pharmaceutical processes.

Building materials industry

Widely used in the mixing of building materials such as cement, putty powder, insulation mortar, dry powder mortar, etc. The processing capacity of a single batch can reach 18m ³, and the mixing time has been reduced from the traditional 45 minutes to 8-12 minutes, significantly improving construction efficiency. Can be paired with an automatic feeding system to achieve fully automated production.

New Energy and Battery Materials

In the production of positive electrode materials for lithium batteries, the ribbon mixer can mix in a nitrogen protected environment (oxygen content<100ppm) to prevent material oxidation and improve battery consistency by up to 18%. The fluctuation of solid content is controlled within ± 0.3% to ensure stable performance of the battery cell. This application has become a key link in the production line of lithium battery materials.

Plastics and Polymer Materials

Suitable for PVC powder dry mixing, plastic coloring, blending modification and other processes. As a low-intensity mixing equipment, the screw belt mixer can evenly disperse additives (such as flame retardants and antioxidants) on the surface of the granules, avoiding excessive shearing and material degradation. Some models are equipped with heating/cooling jackets to meet the temperature control requirements of the process.

Environmental Protection and Waste Management

Used for the mixed treatment of industrial waste such as sludge and carbide slag, combined with chemical agents to achieve stable or resourceful disposal. The continuous operation life of the equipment has exceeded 20000 hours and it has high reliability.
