Rapid Mixture Granulator

Applications :

Pharma FabTM Industries “ Rapid Mixture Granulator (RMG) or also known as 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.

Process :

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

The High Shear Mixer Granulator performs Dry mixing & Wet granulation 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.

  • Flush fitting discharge plug is electro pneumatically operated.
  • Air pursing for seal for both shafts.
  • All internal & external surfaces will be polished for smooth and ease in cleaning.
  • All fabrication will be as per relevant standards and will adopt good engineering practices.
  • All welded joints will be neatly ground to give a smooth finish.
  • Easy and Safety in operation.

OPERATION

  • Dry powders are first loaded into the RMG by vacuum or gravity (total containment).
  • RMG’s are extremely quick and efficient mixers of dry powders. Dry mixing is the first step of the process.
  • After the products are mixed by means of the bottom drive rotating impeller, a binder is introduced into the product.
  • The binder can be added in dry form or sprayed in as part of a binding solution.
  • Spraying occurs though one or more spray nozzles and is quickly dispersed into the product by the mixing action of the main mixing tool (impeller) and the chopper blade.
  • The chopper blade, which is positioned in the highest circumferential area of the product aids in de-lumping.
  • The end point of the granulation is detected by ammeter. Granules are then easily and automatically discharged from a port in the bowl's side. The wet granules are generally milled as they come out of the granulator.

SPECIFICATIONS
