VCH High-Efficiency Modified Mixer

VCH High-Efficiency Modified Mixer Product Introduction
The VCH High-Efficiency Modified Mixer is a multi-functional integrated processing equipment specifically developed for powders, granules, and slurries. It integrates multiple processes such as high-efficiency mixing, surface modification, particle spheroidization, dispersion and crushing, and coating drying, overcoming the pain points of traditional mixing equipment such as low efficiency, poor uniformity, and unsatisfactory modification effects. It adopts a vertical conical cavity combined with a high-speed composite stirring structure to achieve three-dimensional dynamic circulation processing of materials. It is widely applicable to the high-end material processing needs of new energy, fine chemicals, non-metallic minerals, pharmaceuticals, food, and other fields, and is a core piece of equipment for improving product quality and optimizing production efficiency in modern industrial production.

I. Core Working Principle
The equipment adopts a vertical conical closed cavity design. Material is quantitatively fed from the top of the cavity. A high-speed composite rotating shaft and specially designed stirring blades are mounted in the center. During operation, the high-speed rotation of the blades generates centrifugal force, pushing the material against the inner wall of the cone, lifting it upwards along the inner wall to the top of the cavity, and then falling back to the bottom through a special guiding structure, forming a closed-loop cycle of “centrifugal lifting—gravity falling—high-speed shearing”. It can also be equipped with a spray modification system and a temperature control jacket system to precisely inject surface modifiers, coupling agents, and other additives. Combined with temperature control, it completes powder surface coating, modification, and activation during dynamic mixing, ensuring no dead zones or material agglomeration throughout the process. It achieves micron-level uniform mixing and deep modification in a short time, catering to various working conditions such as dry material mixing, slurry treatment, and low-temperature drying.

II. Core Product Features

1. High-efficiency mixing, with uniformity far exceeding conventional equipment: Utilizing a composite stirring structure and a conical cavity, the mixing efficiency is 3-5 times that of traditional V-type and double-cone mixers. A single mixing cycle takes only 30 seconds to 5 minutes, achieving a material mixing uniformity of up to 99.9%, with no stratification, no clumping, and no dead zones. It is particularly suitable for mixing multi-component materials with significant differences in physical properties and specific gravities, completely solving the industry problems of uneven mixing and excessively long mixing times associated with traditional equipment.

2. Precise Modification, Multifunctional Integrated Operation: Equipped with spray modification, particle spheroidization, and post-fusion functions, it allows for precise control of modifier dosage and mixing temperature, achieving uniform coating and activation modification of powder surfaces, optimizing material hydrophilicity/hydrophobicity, dispersibility, and compatibility. A jacketed temperature control system allows for precise temperature regulation of material processing via heating or cooling water, suitable for heat-sensitive and easily oxidized materials. It can also be integrated with a solvent condensation and recovery device to meet environmental protection requirements.

3. Optimized Structure, Stable and Durable Operation: Utilizing a bearing-sinking positioning + composite shaft structure, it significantly improves the rigidity and stability of the main shaft. High-speed operation is free of shaking and deformation, eliminating the risk of equipment “sweeping.” It can withstand high-torque impacts for extended periods, resulting in a longer service life. The material processing area is free of bearings and seals, avoiding material contamination and equipment wear, significantly extending maintenance cycles and reducing subsequent operation and maintenance costs. 4. Sealed and Environmentally Friendly, Clean and Residue-Free: The entire machine is constructed of 304/316L stainless steel with a mirror-polished inner wall. Equipped with a specially designed airtight dome valve, it operates in a completely sealed environment, eliminating dust leakage and meeting environmental production standards. It ensures thorough discharge with an extremely low residue rate. The adjustable drum design facilitates cleaning and maintenance, and eliminates the need for deep disassembly during material changes, preventing cross-contamination. It is suitable for rotating production of various materials.

5. Intelligent and Controllable, Adaptable to Diverse Needs: Supports variable frequency stepless speed regulation. Low-speed start-up during feeding prevents material agglomeration, while high-speed operation allows for flexible adjustment of parameters such as speed, time, and temperature based on material characteristics. Optional features include vacuum feeding, dust removal devices, and an automated control system, enabling fully automated operation of the feeding, mixing, modification, and discharging process, reducing labor costs and ensuring production process stability.

6. Customized Materials for Special Working Conditions: Parts in contact with materials can undergo special treatments such as WC coating and PTFE spraying to isolate metallic impurities, making it suitable for handling corrosive and high-purity materials. Equipment models cover a full range of sizes from 5L to 2000L, and can be customized according to production capacity, material characteristics, and process requirements to meet the needs of laboratory pilot-scale, pilot-scale, and large-scale industrial production.
