SZH Double Cone Mixer

SZH Double Cone Mixer Product Introduction
The SZH Double Cone Mixer is a high-efficiency intermittent mixing equipment specifically designed for powdery and granular materials. It is a classic and universal piece of equipment in the field of powder engineering. Utilizing a double-cone rotating cylinder structure, it differs from traditional equipment such as vertical mixers and V-type mixers. Relying on the uniform rotation of the cylinder to drive the material to omnidirectional tumbling, convection, and mixing, it eliminates strong shearing and material crushing throughout the process, perfectly preserving the original particle shape of the material. It boasts core advantages such as high mixing uniformity, stable operation, simple operation, and environmentally friendly closed-loop system. It is the preferred equipment for achieving uniform mixing of multi-component materials in various industrial fields, suitable for laboratory pilot-scale, pilot-scale, and large-scale industrial production, widely meeting the powder mixing needs of chemical, pharmaceutical, food, and new materials industries.

I. Core Working Principle
The main body of the equipment consists of a double-cone rotating cylinder, transmission system, frame, sealing device, and control system. The cylinder has cylindrical ends and a symmetrical double-cone structure in the middle, all mounted on the rotating bearings of the frame. During operation, the pre-weighed powdered or granular materials are fed into the top of the cylinder through the feed inlet. The feed inlet is then closed and sealed. After starting the equipment, the cylinder rotates at a constant speed driven by the motor and reducer. The materials inside the cylinder undergo a complex process of lifting, falling, convection, and displacement as the cylinder rotates. The multi-component materials are thoroughly mixed in a gentle environment without external pressure or strong shearing. After the preset mixing time is reached, the machine is stopped, and automatic unloading is completed by opening the bottom discharge port. No additional stirring device is required throughout the process; efficient and uniform mixing is achieved solely through the cylinder’s own rotation. This method is particularly suitable for mixing materials with small differences in physical properties, those that are easily broken, and those susceptible to compression.

II. Core Product Features

1. Ultra-high Mixing Uniformity, No Segregation or Dead Zones: The double-cone symmetrical structure combined with a uniform rotation design completely avoids the common problems of bottom sedimentation, uneven local mixing, and material segregation in traditional mixers. Materials achieve three-dimensional circulation mixing within the drum, achieving a uniformity of over 99.5%. Even multi-component materials with slight differences in specific gravity and particle size can quickly achieve a uniform mixing state, eliminating coarse particle and fine powder segregation. This ensures consistent composition in every batch of finished product, fully meeting the requirements of high-precision mixing processes.

2. Scientific Structural Design, Zero Material Breakage and Loss: The machine has no built-in stirring paddles, spiral blades, or other mixing components. Material mixing is achieved solely through the rotation of the drum. The operation is gentle and without impact, strong extrusion, or strong shearing, preserving the original particle shape, crystalline structure, and physical properties of the materials. It is particularly suitable for mixing fragile particles, crystalline powders, and easily agglomerated materials. Simultaneously, it avoids dust generation and excessive loss due to mechanical extrusion, minimizing material waste.

3. Enclosed, dust-free operation, environmentally friendly, hygienic, and easy to clean. The entire cylinder adopts a fully enclosed structure, with a sealing gasket at the feeding port and a sealing butterfly valve at the discharge port. During operation, there is no dust spillage or volatile gas leakage, protecting the production workshop environment, meeting environmental production standards, and preventing material oxidation, moisture absorption, and contamination, ensuring material purity. All material contact parts are made of high-quality 304/316L stainless steel, with a mirror-polished inner wall, smooth, burr-free, residue-free, and non-stick. Cleaning is simple with just a rinse when changing materials, eliminating cross-contamination between different materials and suitable for rotating production of multiple types of materials.

4. Stable operation and low power consumption, easy operation and maintenance: The equipment has a compact overall structure, and the transmission system uses a high-quality motor + reducer combination, resulting in smooth operation, low noise, and minimal vibration. No additional heavy concrete foundation is required, making installation and commissioning convenient. The machine’s operation logic is simple; by presetting the rotation speed and mixing time on the control panel, automatic operation and shutdown can be achieved, eliminating the need for constant personnel supervision and reducing labor costs. The failure rate of core components is extremely low; routine lubrication and maintenance of the bearings are sufficient, eliminating the need for frequent replacement of easily damaged parts and resulting in extremely low maintenance costs.

5. Complete Specifications, Strong Customization Adaptability
The SZH series double cone mixers cover a wide range of specifications, from small laboratory models (10L and 50L) to large industrial production capacities of 500L, 1000L, 2000L, 5000L, and above. Flexible selection based on customer production capacity requirements is possible. Multiple customized configurations are supported, including the addition of vacuum feeders, dust removal devices, spray humidification systems, and jacketed heating/cooling systems. Suitable for mixing hygroscopic, heat-sensitive materials, and materials requiring small amounts of liquid additives, these mixers can be equipped with corrosion-resistant linings and explosion-proof motors to meet the safety requirements of special working conditions and flammable/explosive materials.

6. Thorough Discharge, No Residue Accumulation
The cone-shaped bottom of the drum, combined with a large-diameter butterfly valve, allows for automatic and rapid gravity discharge of materials, ensuring thorough discharge without residue accumulation. No manual cleaning of the drum bottom is required, improving production efficiency and avoiding waste and pollution caused by material residue. This is especially suitable for mixing high-value powders and rare materials.
