Stainless Steel U-shaped Mixer is a high-speed, multi-functional horizontal mixing device. Its core feature is a double or triple-layer spiral agitator within its U-shaped tank. Through the counter-current motion of the inner and outer spiral ribbons, the materials achieve omnidirectional convection circulation and shear mixing within the drum, resulting in high-precision, uniform mixing in a short time.
Whether you need to mix dry mortar, food seasonings, chemical additives, fertilizers, pigments, etc., the stainless steel U-shaped mixer provides a stable mixing solution. Its function is not only to mix, but also, through scientific mechanical design, to ensure that materials with different components and specific gravities achieve ideal mixing uniformity, thereby guaranteeing consistent quality in the final product. In addition, DaHan Machinery supports comprehensive non-standard customization services, tailoring professional equipment to best suit your production needs based on material characteristics, production requirements, and factory layout.
The Stainless Steel U-shaped mixer mainly consists of a U-shaped cylinder, a double-layer spiral mixing device, a transmission system, and a discharge mechanism. Its compact and robust design ensures stable operation.
U-shaped cylinder: The main load-bearing structure of the equipment, made of high-quality stainless steel, with a finely polished inner wall to ensure low material flow resistance and no residue.
Mixing device: The inner and outer spiral ribbons or blades mounted on the horizontal main shaft; this is the core component for mixing.
Transmission system: Composed of a motor, reducer, and coupling, providing stable and controllable power output to the mixing shaft.
Discharge mechanism: Located at the bottom of the cylinder, typically using a manually, pneumatically, or electrically controlled butterfly valve or flap valve to ensure rapid and smooth discharge of mixed materials.
The Stainless Steel U-shaped mixer achieves efficient mixing through a unique two-way mixing principle. When the equipment is started, the motor drives the inner and outer double-layered spiral ribbons on the main shaft to rotate at a specific speed. At this time, the inner spiral ribbon pushes the material near the axis from the center of the cylinder towards both ends; simultaneously, the outer spiral ribbon gathers the material near the cylinder wall from both ends towards the center. This opposite direction of material movement creates strong convection circulation, shear mixing, and diffusion within the U-shaped cylinder. The material not only continuously exchanges positions radially but also repeatedly travels axially, ultimately completing the mixing process.
The Stainless Steel U-shaped mixer offers high mixing uniformity and speed, completing efficient mixing within minutes; it is suitable for a wide range of materials, handling powders, granules, and other materials in various forms; the U-shaped cylinder design results in low residue and easy cleaning; the equipment operates smoothly and reliably, and supports multi-dimensional customization in terms of materials and volume.
Wide Applicability: Effectively mixes materials in various forms, from dry powder and granules to flakes and fibers.
U-Shaped Cylinder Design: The smooth U-shaped trough structure reduces material accumulation and residue on the cylinder wall, facilitating cleaning and maintenance.
Smooth Operation: The horizontal layout results in a low center of gravity and stable operation. Simultaneously, an effective seal at the shaft end prevents material from entering the bearings.
Customizable: Customizable to meet customer needs in terms of material, volume, motor power, discharge method, sealing type, and whether to add heating/cooling or spray functions.
A Stainless steel U-shaped mixer is not only efficient at mixing flour, starch, and seasonings in the food industry, but also suitable for pigments, plastic particles, and detergent raw materials in the chemical industry. It is also suitable for use in the pharmaceutical, building materials, and metallurgical industries.
Animal Feed: Waste, corn, additives, fish feed, pig feed, chicken feed, etc.
Food Industry: Flour, starch, rice flour, food additives, seasonings, spices, cocoa powder, milk tea powder, etc.
Chemical Industry: Various pigments, dyes, coatings, plastic particles, resins, rubber additives, industrial salt, laundry detergent raw materials, etc.
Pharmaceutical Industry: Pharmaceutical powders, traditional Chinese medicine powders, health product raw materials, etc.
While Stainless steel U-shaped mixers are versatile, high-viscosity pastes, pure liquids, and fragile materials extremely sensitive to shear forces are not ideal applications.
High-viscosity materials: These materials easily adhere to the drum wall and the screw conveyor, leading to a significant increase in mixing resistance, difficulty in cleaning, and potentially damage to the equipment.
Pure liquid materials: U-shaped mixers are primarily designed for mixing powders, granules, and other loose materials. For pure liquids requiring high-speed shear emulsification or dissolution, a dedicated liquid mixer or emulsifier is more effective.
Fragile and Sensitive Materials: While U-shaped mixers offer relatively gentle shear force, for highly fragile materials requiring the preservation of intact crystals or granules, a lower speed and gentler mixing method may be necessary.
Choosing the right Stainless Steel U-shaped mixer requires comprehensive consideration of key dimensions such as material characteristics, throughput, mixing time, uniformity requirements, and discharge method.
Material Characteristics: First, the physical and chemical properties of the materials to be mixed must be clearly defined. This includes the material's bulk density, flowability, hygroscopicity, and whether it is corrosive. For corrosive materials, a higher grade of 316L stainless steel should be selected.
Batch Capacity: This is crucial in determining the equipment model. You need to calculate the total weight or volume of materials to be mixed per batch based on your production scale and capacity planning.
Mixing Time: Different materials have different mixing difficulties, and therefore require different mixing times. The advantage of U-shaped mixers is their fast mixing speed, but the specific time needs to be determined experimentally.
Discharge Method: Consider your subsequent process requirements and choose the appropriate discharge method. Common discharge methods include manual butterfly valves, pneumatic butterfly valves, and electric butterfly valves. Pneumatic or electric methods are easier to automate and improve production efficiency.
Determining the specific model and parameters of a Stainless steel U-shaped mixer is a process of translating production needs into technical specifications. First, you need to determine the required throughput and select the appropriate total and effective volumes based on this. Calculate the required motor power according to the material's characteristics, density, and total volume. Then, consider whether the process requires configuration options such as a spray system, heating/cooling jacket, explosion-proof motor, or vacuum feeder.

The price of our Stainless steel U-shaped mixers ranges from $1200 to $20000. The final price is mainly determined by the configuration, with equipment volume/output being the primary factor; the larger the volume, the higher the price. Secondly, the main material is crucial to cost; using higher-grade 304 or 316L stainless steel will be more expensive than carbon steel. Furthermore, adding special functions, such as heating/cooling jackets, spray systems, explosion-proof motors, and pneumatic/electric discharge valves, will significantly increase costs. Finally, the higher the degree of non-standard customization, the more parts need to be designed, molded, and manufactured separately, and the price will increase accordingly.
