Unitfine Oscillating Granulator


Whether it be a wet powder or a pack of dry block materials, the Unitfine Oscillating Granulator will develop the material into fine and consistent granules. The machine comes with an elastically adjustable wire screen mesh that is easy to assemble and disassemble. The main elements of the machine are composed of an enclosed steel-plated body and a lubrication system that enables it to run smoothly without producing any unnecessary noise.

The Oscillating Granulator currently has five models to date and each with different features and output capacity. Production capacity can be 5 to 1500 kilograms per hour. Kilowatt power usage is 0.37 to 15, depending on the model. 55 rounds per minute are the standard rotary drum rotation speed. All models Oscillating rotors can rotate at a 360° angle. Machine weight can go from 65 to 1200 kilograms. The rotating drum diameter is 60 to 350 millimeters.

All the components of this machine adhere to GMP standards.


The working principle of YK series oscillating granulator

Unitfine’s Oscillating Granulator works based on a mechanical granulation process where the material is pressed through a specially designed sieve shaped like a rotor-arm to achieve the needed particle size requirement of different industry sectors. The granulating process is improved by the sieve’s continuous oscillating motion that applies a back and forth pressure to even out the required size distribution of force to the granules.

Only accurately sized particles can pass through the sieve. This is an extra step taken to achieve consistency with the granulated material and imitate the procedure of an experienced pharmacist with swift efficiency. The finished particle granules will then be released into a barrel-like container through the discharging hopper.

An oscillating granulator is a type of pharmaceutical equipment used in the pharmaceutical industry for size reduction and granulation processes. It plays a crucial role in the preparation of granules, which are commonly used in tablet manufacturing. Here are some of the primary applications of an oscillating granulator:

Granulation: The main purpose of an oscillating granulator is to convert fine powder particles into uniform granules. This is essential in pharmaceutical manufacturing because granules flow more easily and uniformly, which leads to more consistent tablet production.

Tablet Compression: Granules produced by the oscillating granulator are often used as the feed material for tablet compression machines. The uniform granules ensure that tablets have consistent weight and content, which is essential for accurate dosing in pharmaceuticals.

Improving Flowability: Fine powders tend to have poor flow properties, making them difficult to handle and process. Granulating these powders using an oscillating granulator can significantly improve their flowability, making them easier to handle in subsequent manufacturing steps.

Dust Reduction: Fine powders can create dust during handling and processing, which can be a concern in pharmaceutical facilities due to cleanliness and safety reasons. Granules produced by an oscillating granulator are less likely to generate dust.

Blend Uniformity: Mixing active pharmaceutical ingredients with excipients is a common practice in tablet manufacturing. Oscillating granulators can be used to prepare uniform granules of this mixture, ensuring even distribution of the active ingredient throughout the tablet.

Drying and Lubrication: Granules produced by the oscillating granulator may undergo additional processing steps such as drying or lubrication to further improve their characteristics before tablet compression.

Reprocessing: In cases where a batch of tablets does not meet quality standards, the tablets can be broken down into granules using the oscillating granulator. These granules can then be reformulated and compressed into new tablets, reducing waste and improving product quality.

Controlled Particle Size Reduction: Oscillating granulators allow for precise control of particle size, making them suitable for producing granules with specific size distributions tailored to the requirements of different tablet formulations.

Overall, oscillating granulators are a valuable tool in pharmaceutical manufacturing, helping to ensure the production of high-quality tablets with consistent dosage and performance characteristics. Their versatility and control over granule size make them a crucial piece of equipment in pharmaceutical production facilities.

Selecting the right oscillating granulator for your specific needs is an important decision that involves several considerations. Here are some reminders and factors to keep in mind when choosing an oscillating granulator:

  1. Application Requirements:
    • Consider the specific application for which you need the granulator. Different granulators may be better suited for certain materials or processes.
  2. Capacity:
    • Determine the production capacity you require. Granulators come in various sizes, and selecting one that matches your production needs is essential.
  3. Material Compatibility:
    • Ensure that the granulator is compatible with the materials you intend to process. Different materials may have different characteristics, and the granulator should be able to handle them effectively.
  4. Particle Size Control:
    • If precise control over particle size is crucial for your process, look for granulators that offer adjustable settings for particle size reduction. Some granulators have variable speed controls and interchangeable screens to achieve the desired particle size.
  5. Ease of Cleaning and Maintenance:
    • Consider the ease of cleaning and maintenance. Granulators should be easy to disassemble and clean to prevent cross-contamination in pharmaceutical applications.
  6. Safety Features:
    • Check for safety features such as emergency stop buttons, safety interlocks, and guarding to protect operators during operation and maintenance.
  7. Regulatory Compliance:
    • Ensure that the granulator complies with relevant industry regulations and standards, particularly in pharmaceutical manufacturing, where compliance with good manufacturing practices (GMP) is essential.
  8. Vendor Reputation:
    • Research and choose a reputable vendor or manufacturer with a track record of producing reliable and high-quality equipment. Read customer reviews and seek recommendations from industry peers if possible.
  9. Budget:
    • Determine your budget constraints and select a granulator that offers the best balance between features and cost. Consider long-term cost of ownership, including maintenance and operational costs.
  10. Support and Service:
    • Inquire about the availability of customer support, spare parts, and maintenance services from the vendor. Having access to support can be essential for troubleshooting and ensuring the longevity of the equipment.
  11. Testing and Validation:
    • If possible, perform testing or validation with the granulator using your specific materials and processes to ensure it meets your requirements.
  12. Energy Efficiency:
    • Consider the energy efficiency of the granulator, as it can impact operational costs and environmental sustainability.
  13. Noise and Vibration:
    • Evaluate the noise and vibration levels generated by the granulator, as excessive noise and vibrations can affect the working environment and potentially lead to operator fatigue or safety concerns.

By carefully considering these factors and conducting thorough research, you can make an informed decision when selecting an oscillating granulator that best suits your manufacturing needs. It’s often beneficial to consult with experts in the field or seek recommendations from peers in your industry to gather additional insights.
