What equipment is used for granulation?
The equipments that could be used for melt granulation are high-shear mixer and fluidized bed granulator.
Which granulation equipment is a high shear granulator with a chopper?
Rapid mixer granulator is widely used equipment in pharmaceutical manufacturing. It is used to mix the pharmaceutical ingredients and make the granules before compression and also called a high shear mixer. Impellers and chopper are mainly responsible for wet granulation in the rapid mixer granulator.
What is granulation machine?
6.3. Granulators are essentially rotary grinders that are used to grind scrap parts and melt delivery systems (sprues and runners) into feedstock sized granules for reprocessing. This allows the molder to reduce waste and produce components more cost effectively.
What is chopper in RMG?
Chopper is designed at the lower side of RMG, which helps break down a large mass of granules into tiny granules. A chopper is used whenever required and operated at a speed of 1440-2880 rpm. The chopper does not have any advantage on the size of granules when the impeller speed is high( about 200 rpm).
How many types of RMG are there?
Mixing Chambers in Rapid mixer granulator is of 3 types Conical shaped , Domed shape , and Circular shaped although the basic aim behind all the shapes is to eliminate the dead points and wall adhesion i.e.the powder may not adhere to wall from where it cannot detach leading to inefficient granulation as well as mixing …
What is the principle of RMG?
Working principle of RMG: Rapid mixture granulator works on agitation, tumbling. The impeller is responsible for uniformly mixing wet granules, and the chopper helps in a break or reduced particle size. At the starting process or during binder addition, the impeller and chopper generally operate at low speed.
What are the advantages of high-shear granulation *?
Main advantages of the GMA high shear granulator: The discharge valve in the center of the bowl at its deepest point guarantees controlled discharge by gravity and impeller support. Top-driven impeller and chopper: no product load in the gasket area.
What is high shear homogenizer?
High shear mixers, also known as high shear reactors (HSRs), rotor-stator mixers, and high shear homogenizers, are used to emulsify, homogenize, disperse, grind and/or dissolve immiscible mixtures with components of the same or different phases.
