    6.What Are The Key Components Of Oscillating Granulator?


    Key Components Of Oscillating Granulator

    The oscillating granulator mainly consists of the following parts:


    The hopper is mainly used to help you load powder or granules into oscillating granulator, and then screen or crush them without wasting materials. It is the feed port of the whole equipment. Not only acts as a storage, the hopper also transports powder or granules to the granulation chamber.


    The rotor is the rotating axis of the oscillating granulator. It mainly consists of a 5-edge arm-like structure, which can provide you with an oscillating mode of rotation, thereby guiding the arm to apply crushing force to the powder or granules. Used to provide stirring force, it can effectively break the material into smaller particles.

    Granulation Chamber

    The granulation chamber is a whole closed structure. It is the main component of the granulator and provides you a closed and clean place for the main material screening or crushing. With a sturdy structure, it can be used for grinding and screening materials of various sizes, shapes, sizes and hardness.


    The sieve is a semi-circular design and installed around the rotor arm in the granulation chamber. By choosing sieves with different mesh sizes, you can sieve granules or powders of different mesh sizes. Particles not sieved successfully will continue to return to the previous step until they are sieved to the predetermined size.

    Discharge Chute

    The discharge chute is installed on the lower side of the oscillating granulator which can help you collect the sieved or crushed materials.

    Mechanical Room

    The mechanical room is usually located on the back of the granulator. It is equipped with mechanical parts such as gearboxes, chains, motors, etc. for your stable and safe operation.

    Electric Room

    The electrical room contains the wires, consumables and other operating buttons of the oscillating granulator. Its drive mechanism can transmit the rotational power to the blades in the processing chamber.

    7.What Is The Working Principle Of Oscillating Granulator?

    Working Principle Of Oscillating Granulator-sourced:

    The working principle of the oscillating granulator is simple and specific:

    Firstly, you need to load the wet or dry powder materials thatneeds into the hopper.

    Then, materials in the hopper will enter the cylindrical screen. Depending on the size of the cylindrical screen you choose, the material will be fed into the high-speed rotating rotor.

    As the rotor rotates, the blades will push the material against the screen wall.

    Due to the centrifugal force generated by the rotation of the rotor, your material will be forced through the perforations.

    This step mainly helps you break the material into smaller particles or particles.

    After that, you can control the size of the particles by adjusting the speed of the rotor and the size of the perforations in the screen.

    Therefore, the material that passes through the screen is collected, while the larger particles continue to circulate in the machine until their size is small enough.

    Finally, these successfully screened materials will be further processed into tablet or capsule granules.

    8.What Is The Wet Granulation And Dry Granulation Of Oscillating Granulator?

    Oscillating Granulator For Wet Granulation and Dry Granulation-sourced: lodhainternational

    The wet granulation and dry granulation are two common granulation processes that you can use binders or compression to combine fine powders into larger granules. Oscillating granulators can be used for both wet and dry granulation.

    Wet Granulation

    The wet granulation refers to a process where a liquid solution is added to the powder, and then some dry powder particles are mixed together by the granulation liquid for your operation. These liquids consist of volatile solvents that can be easily removed by drying.

    Dry Granulation

    Dry granulation is a powder agglomeration method used by the pharmaceutical industry to improve the flowability of your granules by improving the material size (particles). The process of this operation can be performed with the help of roller compactors, with some configurations and different types of equipment designs.
