RHJ Fusion Coating Machine

Product Introduction of Vibration-Melt Fusion Coating Machine

I. Core Product Overview
The vibration-metre fusion coating machine is a new generation of high-performance precision powder processing equipment. It is a core piece of equipment for dry physical modification, breaking through the limitations of traditional mixing, coating, and spheroidizing equipment with single functions. It integrates multiple processes such as efficient mixing, particle compaction, surface coating, morphology modification, and particle spheroidization into one unit. It requires no additional liquid binder, relying on the synergistic effect of high-frequency mechanical force, extrusion force, shear force, and impact force to achieve uniform and dense coating of nano-scale ultrafine powders on the surface of micron-scale particles. Simultaneously, it significantly improves the compaction density of the material and optimizes the physical and chemical properties of the particles. It is a core piece of equipment for the fine processing of high-end powder materials.

The equipment is suitable for processing powders of all particle sizes from nano to micron, accommodating laboratory small-scale and pilot-scale production as well as large-scale industrial production. The entire process is dry, eliminating the need for subsequent drying steps, making it energy-saving and environmentally friendly. It can handle various difficult-to-process materials, including those that are heat-sensitive, abrasive, and highly adhesive, and is widely applicable to the high-end material preparation needs of new energy, new materials, chemical, and electronic fields.

II. Core Working Principle The equipment employs a horizontal cylindrical cavity paired with a high-speed, specially designed rotor structure. The rotor’s linear velocity can reach 30-40 m/s. Under centrifugal force, the material adheres tightly to the cavity wall, circulating at high speed between the rotor and stator extrusion head. It is continuously subjected to four forces: three-dimensional high-frequency vibration, high-intensity extrusion, precise shearing, and instantaneous impact. This causes thorough friction, kneading, and embedding between particles, achieving physical fusion and coating of two or more materials. Simultaneously, controllable mechanical force breaks up nanoparticle agglomerations, allowing ultrafine auxiliary materials to uniformly adhere to the surface of the main material particles, forming a dense, non-detaching coating layer. This simultaneously completes particle compaction and spheroidization, improving material bulk density and flowability.

The equipment comes standard with a water-cooled jacket system for the cavity, precisely controlling the internal temperature to prevent material degradation and adhesion to the cavity, ensuring safe processing of heat-sensitive materials. An optional inert gas protection device can be added to achieve oxygen-free, dust-free, and sealed operation, ensuring the processing stability of easily oxidized materials.

III. Core Product Features

1. Multifunctional Integration, One Machine for Multiple Uses, Cost Reduction and Efficiency Improvement
Breaking through the limitations of traditional equipment’s single-process capabilities, a single machine can complete the entire process of mixing, dispersing, coating, compaction, spheroidizing, and surface modification. This eliminates the need for multiple machines operating in series, reducing process transfers and material losses, shortening the production cycle. A single batch of conventional materials can be processed in just 3-5 minutes, far exceeding the production efficiency of traditional mixers and coating machines, significantly reducing equipment investment and site occupancy costs.

2. Uniform and Dense Coating, Excellent Compaction Effect
Utilizing a precise mechanical control design, it achieves full and uniform coating of nano-level auxiliary materials on the surface of the main material, with a coating rate exceeding 99%. The coating layer is dense and firm, without peeling or agglomeration, effectively solving industry pain points such as uneven mixing and poor dispersion of trace auxiliary materials in traditional methods. Simultaneously, it improves the material’s compaction density, reduces specific surface area, optimizes material filling performance, conductivity, and sintering performance, and enhances the quality of the final product.

3. Dry Physical Modification, Environmentally Friendly and Residue-Free: The entire process utilizes a purely physical processing method, without the addition of binders, solvents, or other chemical additives. There is no wastewater, waste gas, or waste residue discharge, meeting green production standards. Processed materials require no drying or cleaning post-processing steps and can directly enter the next production stage. The material has high purity and no chemical residue, suitable for the stringent purity requirements of high-end materials.

4. Precise Temperature Control and High Adaptability: Standard configuration includes a full-cavity water-cooled jacket structure, which removes heat generated by mechanical friction in real time, precisely controlling the internal temperature and stably processing heat-sensitive and low-melting-point materials. Parts in contact with materials are made of 304/316 stainless steel, tungsten carbide hard coating, or ceramic materials, providing wear and corrosion resistance and preventing metal impurities from contaminating the material. Suitable for highly abrasive and highly adhesive materials. Supports variable frequency speed control and customizable parameters, allowing for flexible process adjustments based on different material characteristics, suitable for processing various powder materials.

5. Intelligent and Convenient, Low Maintenance Costs
Equipped with a touchscreen intelligent control system, parameters are visualized and monitored in real time. Operation is simple and easy to understand, allowing even beginners to quickly learn. The chamber uses a sliding rail quick-disassembly design, making disassembly, cleaning, and material replacement convenient. Residual levels are less than 0.1%, eliminating cross-contamination between batches of materials. The equipment has a compact structure, stable operation, low noise, few vulnerable parts, low maintenance costs, and a long service life.

6. Sealed and Safe, Adaptable to Special Working Conditions
The entire machine adopts a sealed structure and can be equipped with an inert gas (nitrogen, argon) protection system to achieve slightly positive pressure sealed operation, effectively preventing material oxidation and moisture absorption. It is suitable for the safe processing of easily oxidized materials such as lithium battery materials and magnetic materials. An exhaust filtration device is included to prevent dust leakage, ensuring a clean production environment and operator safety.
