• Rapid Mixer Granulator is designed to achieve excellent mixing and consistent granules at lower

• operating cost along with higher productivity. Better mixing and closed control of granule size

• leads to faster tableting speeds with improved quality and least rejections

Working Principle of rapid mixer granulator

• Blending and wet massing is accomplished by high mechanical agitation by an impeller chopper.

• Mixing, densification, and agglomeration of wetted materials are achieved through shearing and compaction forces exerted by the impeller

• The impeller rotates on the vertical shaft at a rotational speed corresponding to a radial blade tip speed of approximately 5-15 m/s. the chopper rotates at a similar tip speed which, because of its small diameter corresponds to a very high rotation speed in revolutions per minute (rpm)(i.e. 1500-4000 rpm).

• The primary function of chopper is to cuts lumps into smaller fragments and aids the bowl or sprayed onto the powder to achieve a more homogeneous liquid distribution

CONTROL PANEL

• Control Panel is made up of S. S. sheet metal• It is with special feature DISPLAY SYSTEM and

MICRO PROCESSOR with member keys.• Display system consists of indicator lamps for

compressed air supply, main motor, chopper motor, bowl lid limit switch and for closed / open status of discharge valve

• In case of insufficient compressed air supply pressure switch contained in the panel will prevent the machine from starting

• Limit switch is provided on main bowl lid, and discharge valve,which will de-energies the system when the lid is open
