What is a Rotary Granulator?
It is a wet granulator that processes wet materials into uniform granules through the combination of extrusion and rotation. Unlike rotary drum granulators, it is suitable for small to medium batch production. A rotary granulator is often used in conjunction with mixers and dryers.
Working Principle of Rotary Granulator
Material addition: The treated wet material is fed into the extrusion rollers of the rotary granulator. The moisture content is usually 10-15% to ensure that the wet material can be extruded into shape.
Extruded Material: The pre-compression device compacts the material and pushes it into the granulation room. The extrusion rollers rotate at high speed, forcing the compacted material into a mold with holes. The material is then extruded through the holes of the mold.
Discharge: The extruded particles are cut into appropriate lengths by a cutting device and discharged from the discharge port.
Key Components of Rotary Granulator
Feeding Device
The feeding device consists of a hopper and a feeding tube. FANQUN rotary granulators offer rotary granulators with automatic feeding devices, which can feed materials into the hopper evenly and continuously, avoiding hopper blockage caused by overfeeding.
Extrusion Roller
It is also known as a spiral impeller, and it is made of high-strength alloy steel, which is wear-resistant. It is used to agitate materials, ensuring uniform distribution. The special design of the spiral reduces heat generation during its rotation, protecting heat-sensitive materials.
The rotational motion of the extrusion roller helps separate viscous materials, making them more fluid during extrusion.
Molds
Different apertures and shapes of the molds are designed according to particle diameter. FANQUN rotary granulators can custom mold opening inclination and channel length-to-diameter ratio to your required particle size. The molds have no obstructions on the sides, which is convenient for the discharge of viscous materials. We offer both fixed and removable molds. The removable molds are easy to clean.
Structures Made of Stainless Steel
The parts that directly contact the materials are made of 316L stainless steel, which is more corrosion-resistant than 304L stainless steel. These stainless steels are polished to achieve a smoothness of Ra≤0.8 μm. Even highly viscous wet materials have difficulty adhering to it.
Parts that don’t directly contact the materials are made of 304L stainless steel, which is also smooth and easy to clean. Our dryers meet GMP hygiene standards.
Applications of Rotary Granulator
Chemical Industry
Pesticide powders: talc, granules.
Fertilizers: Organic fertilizers such as compost and bone meal. Inorganic fertilizers such as urea, ammonium bicarbonate, and superphosphate. For fertilizers with high corrosivity, the FANQUN organic fertilizer granulator uses a ceramic-coated extrusion roller, which can easily cope with the corrosivity of fertilizers.
Ceramic materials: clay, kaolin. For ceramic materials with certain viscosity, the rotation speed of the extrusion roller should be appropriately increased to enhance dispersion to prevent them from clogging the holes in the mold during extrusion.
Catalysts: Manganese dioxide, iron powder, enzymes. The size and shape of the catalyst have a significant impact on its catalytic effect. Our rotary granulator can precisely control the parameters.
Pharmaceutical Industry
For the pharmaceutical industry, hygiene standards are a key factor in evaluating granulators. Our rotary granulators have hygiene documents, including material certificates, surface finish reports, and microbial removal rate test reports.
Active pharmaceutical ingredients: antibiotics, protein drugs, sterile raw materials.
Additional ingredients: lactose, starch, magnesium stearate, talc, etc.
Traditional Chinese medicine granules: Cold and Fever Relief Granules, Xiangsha Yangwei Granules, Shuanghuanglian Granules, etc. The high viscosity and easy solubility of Chinese medicine granules make them difficult to handle. FANQUN rotary granulators precisely process Chinese medicine granules by adjusting pressure and humidity.
Food Industry
Before processing food, we assess the risks of microbial contamination, chemical residues, and physical contamination to ensure that surfaces that directly contact food are safe and sterile. If you have requirements for CE certification, we can conduct the CE certification for your custom rotary granulator.
Candy, sugar mixtures, malted milk. These foods require a high level of palatability.
Functional ingredients: protein powder, vitamins, minerals, dietary fiber, probiotics, unsaturated fatty acids
Food powders: instant beverage powders, seasonings, baking powders, etc.
Environmental Protection
Solid waste treatment agents: solidifying agents, adsorbents such as activated carbon
Soil conditioners: humic acid, seaweed extract, lime, silicates, microbial agents, etc.
Advantages of Rotary Granulator
Environmentally Friendly
Unlike dry granulation, rotary granulators use wet granulation, which avoids material wear and dust formation. This wet granulation method can significantly improve the air quality in the production workshop and improve the working environment. This also eliminates the risk that dust pollutes other processing equipment.
Good Adaptability
Rotary granulators can adapt to various materials, while some other granulators limit the sizes, viscosity, and pH of materials.
The molds and extrusion rollers are polished and coated to adapt to materials of different viscosities. The low-shear design of the extrusion roller kerf and the pressure control system of the pre-compression device protect the material’s structure. The modular design allows for flexible adjustment of the loading volume according to the material’s volume.
Stable Operation
The support structure of the rotary granulator uses a steel plate welding process, improving stability during operation. Even when operating at high speed and full load, the granulator body can still maintain a vibration value 30% lower than the industry standard, ensuring stable operation and preventing parts from loosening due to severe vibration.
High Automation
Rotary granulators have a high degree of automation and are easy to operate. Workers only need to set related parameters before the operation, and don’t have to supervise during the operation. If the granulators malfunction during operation, they can automatically stop to avoid material loss.
Technological Breakthroughs of FANQUN Rotary Granulators
FANQUN rotary granulators develop new technologies based on technological innovation and market demand.
Artificial Intelligence Control System
This system precisely monitors various parameters and automatically adjusts to adapt to the operation process. It can not only improve granulation efficiency by 10-15%, but also reduce the differences between production batches through precise parameter adjustment by artificial intelligence.
Environmentally Friendly Materials
Some of FANQUN’s rotary granulators are made with sustainable materials, which not only protect the environment but also reduce energy consumption during the production process. These environmentally friendly materials are precisely assembled to achieve a material loss rate of less than 1%, reducing production waste.
Modular Installation
The loading volume can be flexibly adjusted because of the modular system. It is easy to install. If the granulator needs to be cleaned, the easy-to-disassemble clips and bolts allow operators to complete the entire disassembly process within 10 minutes, shortening the half-time compared to traditional cleaning.
