Vertical Mixer | High-speed Uniform Mixing Equipment for New & Recycled Plastic Materials and Color Masterbatch

The vertical mixer is an essential pretreatment auxiliary equipment in the plastic processing industry, featuring rapid homogenization and high-efficiency material mixing functions. It is widely used for stirring and blending various plastic particles, new and recycled raw materials, and color masterbatch. With the advantages of uniform mixing, wide adaptability, and customizable design, the vertical mixer has become the core auxiliary equipment for injection molding, extrusion, and pelletizing production lines.

In plastic production and processing, uneven raw material mixing, scattered color masterbatch distribution, and disordered proportioning of new and recycled materials easily cause finished product chromatic aberration, uneven texture, and batch defective products, directly affecting product qualification rate and production efficiency. Traditional simple mixing equipment features slow stirring speed, numerous mixing dead angles, and severe material stratification, failing to meet standardized mass production requirements. Optimized in structure, this vertical mixer delivers fast stirring speed and high mixing uniformity, specifically solving the mixing difficulties of new/recycled plastic materials and color masterbatch. The barrel is available in two materials: stainless steel and A3 iron to adapt to different material processing requirements. It also supports non-standard customization with full gradient models from 1 ton to 5 tons, fully meeting the capacity demands of small, medium, and large plastic processing factories, serving as a highly cost-effective plastic vertical mixing machine.

1. Detailed Introduction to Core Accessories and Product Value

Vertical Spiral Stirring Main Shaft: As the core stirring component of the vertical mixer, it adopts a vertical spiral lifting structure. During operation, the spiral blades continuously lift materials from the bottom to the top, and the materials fall back naturally to form a circulating vortex, completely eliminating material stratification and sedimentation. Compared with horizontal mixing structures, the vertical circulating mixing design has no dead angles and achieves more uniform material mixing with greatly improved stirring speed. It perfectly adapts to the homogeneous mixing of plastic particles, color masterbatch, and new/recycled mixed materials, fundamentally avoiding finished product chromatic aberration and uneven texture.

Integrated Mixing Barrel: Two mainstream barrel materials are available: stainless steel and A3 iron. The stainless steel barrel is corrosion-resistant, rust-proof, and easy to clean, suitable for high-precision and high-cleanliness plastic raw materials and light-color color masterbatch stirring without material contamination risks. The A3 iron barrel features high hardness, impact resistance, and high cost performance, ideal for processing ordinary industrial plastics, dark-color materials, and recycled waste materials, matching different production budgets and material standards.

Gradient Power Motor: Equipped with 4HP-10HP pure copper power motors with stable power output, sufficient torque, low noise, and strong durability. The power is accurately matched according to 1T-5T different production capacities. Small models save energy and reduce consumption, while large models provide sufficient power to support continuous circulating stirring of large batches of materials, ensuring no overheating or jamming during long-term continuous operation and stable production line operation.

Integrated Reinforced Frame: The whole machine adopts a reinforced frame structure with strong support and stable operation. No severe vibration or displacement occurs during stirring, effectively reducing equipment loss and extending the overall service life. The compact structure occupies a small floor area, allowing flexible workshop placement without dedicated installation space, adapting to various production line layouts.

Application Fields: Widely applicable to plastic injection molding factories, plastic pelletizing production lines, film extrusion workshops, and plastic product manufacturing enterprises. Specialized in mixing new/recycled plastic materials, color masterbatch toning, and plastic particle homogenization blending operations.

5. FAQ

vertical mixerQ1: Will the  cause uneven mixing and chromatic aberration when blending new/recycled materials and color masterbatch?

A: No. Adopting a vertical spiral circulating vortex mixing mode, the equipment realizes up-and-down circulating homogenization of materials without dead angles or stratification. New and recycled materials are highly fused with evenly dispersed color masterbatch, fundamentally eliminating finished product chromatic aberration and uneven mixing defects to meet the high-precision production requirements of plastic products.

Q2: How to choose between stainless steel barrel and A3 iron barrel?

A: For producing light-color, high-cleanliness, and high-precision plastic products, the stainless steel barrel is preferred for rust prevention, pollution avoidance, and easy cleaning. For processing dark-color recycled materials and ordinary industrial plastics with cost-performance priority, the A3 iron barrel is ideal with wear resistance, durability, and low investment cost.

Q3: Does the equipment support non-standard size and special capacity customization?

A: Yes. This vertical mixer supports personalized customization services. Exclusive size, material, and configuration solutions can be customized according to customers’ workshop space, material characteristics, and special capacity requirements.
