Rapid mixer granulator working principle: A simple explanation!
Pharmaceutical factories use rapid mixer granulators to manufacture tablets and granules. This machine mixes and granulates powders to prepare them for tablet making. RMG is also used in the food and chemical sectors. If you are curious to know how this machine works, this blog is a must-read. This post explains the rapid mixer granulator working principle and main components.
It is a high-speed mixer that provides homogeneous powder mixing and produces high-quality granules quickly. This machine combines mixing and granulation in a single process. The mixer ensures that dry ingredients are blended evenly, and then the addition of a granulating fluid helps form uniform granules.
Basic overview of a rapid mixer granulator
In RMG, mixing, densification, and agglomeration are accomplished by shear mixing (breaking intermolecular interactions) and compaction forces produced by the impeller on the powder mass. RMG comprises a mixing chamber, an impeller, a chopper, a discharge port, a filter assembly, purging air, and a solution inlet port.
The RMG has three types of mixing chambers. Conical, domed, and circular forms are all used to eliminate dead spots and wall adhesion, which means that the powder may not stick to the wall, from which it cannot separate.
Rapid Mixer Granulator Working Principle Explained in Simple Steps!
- First, all the dry ingredients or powders are added to the mixing chamber. The impeller rotates and mixes the powder or ingredients.
- After that, a liquid binder is sprayed or poured into the mixing chamber to bind the dry powder mixture.
- The impeller rotates again to spread the liquid binder in the chamber.
- Next, the chopper operates to break any large lumps and transform them into tiny wet granules.
- You can adjust the speed of the impeller and chopper according to your requirements.
- After granulation is complete, you can take out the wet granules from the machine and proceed with further drying.
You can refer to the rapid mixer granulator guide or manual that comes with the product before operating it. The manual contains details about the specific model of the machine, including how to operate and maintain an RMG.
Points to consider while planning a rapid mixer granulator:
Some of the major elements that are closely associated with RMG and demand consideration when preparing for an RMG are as follows:
Capacity and Space Planning:
RMG capacity should be designed using two key parameters: (a) bottlenecking capacity of the whole granulation line and (b) space availability.
A rapid mixer granulator often requires a considerable space (due to the operation platform and ladder). Furthermore, several associated activities, including sifting, milling (co-milling or multimilling), drying, and so on, are preferentially performed in the same area where RMG is located. In addition, the mass mixer and paste kettle used before granulation are occasionally housed in the same room.
Given all of this, space can become a bottleneck that can affect capacity and batch planning.
Ancillary Equipment Planning:
As previously noted, the capabilities of relevant ancillary equipment, such as paste kettles, blenders, dryers, mass mixers, and other granulation line equipment, as well as mass transfer equipment such as lifters and loaders, must be carefully designed.
Material selection and surface finish:
Material selection is performed based on whether the operation is GMP or non-GMP. Unusually, the surfaces are exceptionally smooth, and the finish has a high RA value to prevent corrosion.
Ergonomic design:
Every feature of the design, such as the ladder, railing, top lid, material charging nozzle, platform height, discharge mechanism, and operation panel, should be ergonomic. This is critical not just for operator safety but also for enhancing efficiency, quality, and productivity.
Final Thoughts
The rapid mixer granulator working principle shows how effective mechanical design and controlled motion can simplify the mixing and granulation process. It is a high-quality mixer/processor that may be used for both high-speed dispersion of dry powders and granulation with aqueous or organic liquids. The equipment offers quick mixing and the generation of granules necessary for the manufacturing of high-quality pharmaceutical tablets in solid dosage forms of medicine.
