Osclillating Granulator

High Speed Uniform Granulation Process

Application & Process :

Oscillating Granulator is used for gentle homogenization, size reduction, grading and sieving of dry, sensitive powders and granules in pharmaceutical, chemical and food industries.

Oscillating Granulator has one rotor with five edges, which oscillate on horizontal axis at about 180 per minutes. There is one half round sieve mounted at the bottom of the rotor. Product is charged from the top through in feed hopper and material falls on the rotor lades. The particles are broken by a set of oscillating bars arranged in cylindrical form over a screen of suitable mesh. Due to the sharp edges on rotor, the downsizing of particle takes place and through sieve material gets pushed outward from the bottom opening.

High Shear Mixer Granulator-HSMG / Rapid Mixer Granulator - RMG

Application & Process :

The High Shear Mixer Granulator used for process of fast dry & wet mixing, homogenizing, humidifying and granulating of the powder in Pharmaceutical, Chemical, Cosmetic, Food, Plastic, General Mixing Industries.

High Shear Mixer Granulator series is characterized by the compact construction, modern design and all the user and maintenance friendly attributes which form the ergonomics design aspects are essential for a wide range of application.

The High Shear Mixer Granulator performs dry mixing & wet granulating by basic design of the special four arm of the mixing impeller and sequences of the mixing process in the cylindrical mixing drum with rounded connection to the base plate, achieve another special effect. The mixing process runs without varying pressure zone in the volume of mixing product. Separately driven multiple choppers can effectively intensify the mixing result in particular when liquid or paste components are added. During humidifying and granulating process of the products the chopper controls and regulates the granular spectrum and structure of the granules according to the product, chopper shape and time. The HSMG system requires only small quantities of granulating liquid or pastes to obtain the required granulate structure. This reduces the amount of drying energy required.

Uniform Spheronize pellets Process

Application & Process :

This machine is particularly designed for pharmaceutical, food and chemical laboratory small batch tests. Spheronizer enables uniform coating and accurate free flow filling into capsules drug applications within the pharmaceutical industry require consistent smooth surface particles, with a narrow size distribution.

Spheronization helps to eliminate dust within the agro-chemical, pigment, and catalyst industries. This can reduce the risk due to toxic, environmental, and explosive hazards. It also improves processing consistency and productivity by using consistent free-flowing product and to reduce product settlement in transport of powder products prior to packaging.

Spherodizer (also known as spheroinizers) provide a spherical product that is a more attractive as well as higher performing final granular product form than unspheronized. The Spheroinizers are implemented to produce uniform spheres for a wide range of technical as well as marketing driven reasons. Spheroidization can be used to improve the following:

  1. Limit dusting and fines generation
  2. Produce granule with a smooth surface
  3. Densify the surface for stability
  4. Minimize coating material necessary
  5. Increase flow ability
  6. Increase bulk density

Narrow size distribution is controlled through the use of one of Prism's extruders such as Basket Extruder or Axial extruder to define the diameter of the feed material for the Spheronization Process.

Feed material to the Spherodizer falls onto the high speed rotating chequered plate within the walls of cylinder of Spheronize of pellets. This plate contains many small sharply edged pyramids which cut the feed granulates to length at approximately 1 to 1.5 times their diameter. Centrifugal and gravitational forces create a mechanically fluidized ring of these particles which are impacting not only the plate but also each other and the walls with great velocity. With these impacts, they are reformed into spheres with a slight surface densification. Fines which were generated during the process are worked back into the spheres themselves leaving a very low dusting process with spheres which tend not to dust because of their slightly harder exterior and lack of corners.

Variables for this Spheronization process include the formulation, the plate's pyramid sizes, the plate's rotational speed, and finally the time that the granules are allowed to stay inside the spheroinizers.

Batch processing is typical for the requirements of pharmaceutical applications while the larger industrial Spheronization applications often employ the higher capacity cascade Spheronization method where granules are continuously moving through 2 or more Spherodizer bowls in a cascade layout to create the final spherical form required.

Pharmaceutical spheroinizers are available with capacities from 0.25 Kg per batch to 60 Kg per batch. Industrial cascade spheroinizers with capacities to 100 Kg per batch are available.
