rotary drum powder mixer, drum plastic color mixer
A rotary drum powder mixer, also known as a drum blender, is a type of equipment used for mixing powdery and granular materials.
Drum stainless steel mixer is a new type, high efficiency, fine container rotary, mixing equipment, used for all kinds of powder, granular materials mixed evenly, with a very high mixing degree, for the small number of ingredients can also achieve a better mixing degree; The machine adopts mechanical seal, the powder will not leak, the bearing service life is long; The machine has high mixing efficiency, high working efficiency, low labor intensity, and easy operation. Can be used in magnetic powder, ceramics, chemical, pharmaceutical, feed, and other industries.
Working Principle
Rotary Drum Mixer rotates 360 degrees. There are mixing blades in the middle of the mixer. When the mixer runs, the mixing blades rotate at the same time. The rotating drum causes the materials in the drum to tumble and mix chaotically, and the high - speed rotating mixing blades break the agglomerated materials, so that the materials are quickly mixed in the drum.
Features：
1.The barrel is made of stainless steel, welded firmly, bright surface, easy to clean
2.360-degree rotation of all-around mixing, feeding, material arbitrary positioning, easy to operate
3.The timer can select the mixing time between 0 and 30 minutes
4.Applicable for mixing the plastic color powder, new and old materials, forage, food, and other mixing purposes
5.Overload protection device for safe operation
Drum stainless steel mixer has the characteristics of simple structure, reasonable, convenient maintenance, small power, safe and reliability, high mixing uniformity, no residue, good sealing, and so on. It is suitable for mixing powder additives and trace elements in many industries.
Rotary drum powder mixers, with their core advantages of high mixing uniformity, zero material segregation, and compatibility with a wide range of powders/granules, are widely used in industries requiring precise mixing, cleanliness, or production efficiency. Specific application scenarios are as follows:
1. Food Industry
Core requirements: Meeting food safety standards (e.g., 304/316 stainless steel), residue-free mixing, and adaptability to the powder/granule characteristics of food ingredients. Typical Applications:
Basic Ingredient Mixing: Blending flour with grain flours (e.g., whole wheat flour, buckwheat flour), and blending starches (corn starch, potato starch) with improvers;
Seasoning/Additive Mixing: Premixing basic seasonings such as salt, sugar, and MSG; compounding spice powders (chili powder, pepper, cumin powder); and evenly dispersing food additives (preservatives, flavor enhancers) into main ingredients;
Specialty Foods: Formulating meal replacement powders (protein powder, oatmeal powder, fruit and vegetable powders); and precisely blending infant food powders (rice flour with nutritional supplements).
2. Pharmaceutical Industry
Core Requirements: GMP (Good Manufacturing Practice) compliance, extremely high mixing precision (to avoid uneven drug efficacy), and easy-to-clean equipment (to prevent cross-contamination). Typical Applications:
Solid Pharmaceutical Raw Material Mixing: Mixing tablet/capsule raw material powders (such as antibiotic powder and vitamin powder) with excipients (filler lactose, binder starch);
Traditional Chinese Medicine Powder Processing: Compounding of pulverized Chinese herbal medicine pieces (such as angelica powder and astragalus powder), or uniformly mixing Chinese herbal extract powders with diluents;
Pharmaceutical Excipient Preparation: Premixing of pharmaceutical coating powders and disintegrants (such as cross-linked polyvinylpyrrolidone).
3. Chemical Industry
Core Requirements: Compatibility with chemical powders of varying specific gravities and particle sizes, tolerance to some corrosive materials (requiring special materials), and sufficient mass production efficiency. Typical Applications:
Plastics/Rubber Industry: Mixing plastic particles with masterbatches and antioxidants, and premixing rubber additives (vulcanizers, accelerators) with rubber powder.
Coatings/Pigment Industry: Uniform dispersion of pigment powders (titanium dioxide, carbon black), fillers (talc, calcium carbonate), and resin powders (to avoid color shift).
Other Chemical Industries: Color matching and mixing of dye powders, mixing of pesticide wettable powders (technical powder with dispersants and fillers), and premixing of fertilizer granules (such as compound fertilizers) with trace elements (boron fertilizers, zinc fertilizers) before coating.
4. Metal and Metallurgical Industry
Core Requirements: Adapting to the high density of metal powders, ensuring seamless mixing (to avoid gravity segregation), and ensuring uniform composition for subsequent processing (such as sintering and pressing). Typical Applications:
Metal Powder Preparation: Adjusting and mixing the composition of alloy powders (such as aluminum alloy powder and stainless steel powder); mixing magnetic material powders (ferrite powder and NdFeB powder) with binders;
Metallurgical Auxiliary Materials: Premixing deoxidizers (ferrosilicon powder and ferromanganese powder) and slag-forming agents for steelmaking and ironmaking; mixing metal ore powders (such as iron ore and copper ore) with reducing agents (coke powder).
5. Building Materials and New Materials Industry
Core Requirements: Adapting to the roughness of inorganic non-metallic powders and ensuring high stability of the mixed material (to avoid cracking and uneven performance). Typical Applications:
Cement/Mortar: Mixing specialty cements (such as rapid-hardening cement) with admixtures (water reducers, early strength agents); formulating and mixing dry mortars (cement, quartz sand, cellulose ether) (tile adhesive, putty powder);
Ceramics/Refractory Materials: Mixing ceramic body powders (kaolin, feldspar powder) with colorants; premixing refractory powders (alumina powder, mullite powder) with binders;
New Materials: Mixing lithium battery cathode materials (lithium iron phosphate powder, ternary material powders) with conductive agents (carbon black, graphite powder); and homogenizing the composition of photovoltaic glass raw material powders.
6. Feed Industry
Core Need: Adapting to the "powder + granular" mixing scenario of feed to ensure uniform distribution of nutrients (such as vitamins and minerals) and prevent uneven feeding of animals. Typical Applications:
Livestock and Poultry Feed: Mixing base feed powder (corn meal, soybean meal) with premixes (vitamins, trace elements, amino acids);
Aquaculture Feed: Mixing fish/shrimp feed powder with attractants and mildew inhibitors, which can then be pressed into pellets.
In summary, the core application of this equipment is to solve the common problem of "uniform mixing of powders/pellets." Therefore, it plays an irreplaceable role in industries that require precise control of material composition. The equipment's materials (such as 316L stainless steel) and internal structure (such as a special scraper design) can be customized to meet the specific requirements of different industries (such as cleanliness, corrosion resistance, and mixing accuracy).
