DETAILS

The vertical disc mixer—also known as vertical mixer—is a piece of equipment that utilizes a vertical disc as its main mixing vessel and achieves material blending through the high-speed turning action of mixing teeth or arms. The machine primarily consists of a mixing disc, a discharge outlet, mixing arms, a frame, a gearbox assembly, and a drive mechanism. The inner wall of the disc is typically lined with polypropylene or stainless steel sheeting to minimize the adhesion of high-moisture, sticky materials during the mixing process.

How does a vertical disc mixer mix ingredients?

The core working principle of the vertical disc mixer can be summarized as the combination of “centrifugal throwing” and “gravity diffusion”. The main body of the equipment is a rotating disc placed vertically, with several groups of scraping plates arranged at specific angles installed on the bottom of the disc. When the motor drives the disk to rotate at a high speed, the material falls into the disk from the top feed port, is instantly taken to a high place by the material transfer plate, and is then thrown down in a parabola under the action of gravity.

In this process, tens of thousands of collisions, interpenetrations and diffusions occur between material particles, allowing different raw materials with huge differences in specific gravity to be fully intertwined. Compared with horizontal mixing, the vertical structure effectively utilizes gravity potential energy and reduces mixing dead corners. The residence time of the material in the disk can be precisely controlled by adjusting the disk speed and the height of the discharge port, and the mixing uniformity can reach more than 98%.

In terms of transmission, the electric motor drives the high-torque cycloidal pinwheel reducer to run, and the reducer drives the main shaft, and the main shaft drives the mixing teeth to stir the material. This transmission method has compact structure, smooth operation and low noise.

Application Scenarios for Vertical Disc Mixers

Vertical disc mixers are primarily suitable for the following applications:

Organic fertilizer production: Mixing fermented livestock and poultry manure (such as chicken or sheep manure) with additives like straw powder, humic acid, and microbial agents.

Compound fertilizer processing: Blending organic raw materials with chemical fertilizers according to specific formulations.

Construction materials and chemical industries: Pre-mixing and conditioning of powdered or granular dry materials.

Why Choose the Huaqiang Heavy Industry Vertical Disc Mixer?

1. Uniform Mixing, Compatible with Diverse Fertilizer Raw Materials

The Huaqiang vertical disc mixer utilizes multi-angle alloy mixing teeth to drive the material in a multi-dimensional, convective tumbling motion. This ensures the thorough blending of livestock manure, powdered straw, and chemical additives, achieving high mixing uniformity. It effectively handles moist, sticky materials with moisture content between 20% and 35%, preventing clumping and nutrient stratification while enhancing the quality of the final granulated product.

2. Compact Structure, Saving Energy and Space

Featuring a sophisticated vertical disc layout, the equipment occupies only one-third of the footprint of a horizontal mixer with equivalent capacity, making it suitable for installation in confined workshops. The optimized drive system reduces power consumption, leading to electricity cost savings during long-term production. The machine body is robust and wear-resistant, featuring wear-resistant liners and durable mixing teeth.

3. Clean Discharge, Easy Maintenance and Servicing

The well-designed bottom discharge mechanism minimizes material residue, reducing the risk of cross-contamination when frequently switching fertilizer formulas. Access ports facilitate easy removal and installation of wear parts like mixing blades, while routine cleaning and maintenance are quick and effortless, minimizing downtime.

4. Strong Manufacturing Expertise and Comprehensive After-Sales Support

With over two decades of experience in fertilizer processing equipment manufacturing, Huaqiang Heavy Industry offers a wide range of models suitable for small, medium, and large-scale organic fertilizer production lines. The equipment is user-friendly and easy to operate; furthermore, the company provides comprehensive technical guidance and after-sales maintenance services to ensure smooth and reliable fertilizer production operations for customers.
