In the fast-paced world of pharmaceutical manufacturing, high-shear granulation has become a game-changer. This process ensures that your solid dosage forms are consistent, efficient, and of the highest quality.
For procurement professionals, understanding the value of a high-quality High Shear Mixer Granulator (often referred to as RMG) helps in making smarter purchasing decisions that directly impact production success.
What Is High-Shear Granulation (RMG)?
High-shear granulation is a typical wet granulation technique where powders are mixed and agglomerated. This is achieved using a machine known in the industry as a Rapid Mixer Granulator (RMG).
This method involves intense mechanical forces that rapidly combine powders with a liquid binder, forming granules with uniform size and density. It is widely used in pharma to improve powder flow, compressibility, and content uniformity.
Key Benefits of Using a High Shear Mixer
Excellent Content Uniformity & Consistency
Ensures even distribution of active pharmaceutical ingredients (APIs).
Reduces batch-to-batch variability, a key feature of Jianpai’s High Shear Mixer.
Enhances dosage accuracy.
Superior Particle Mechanical Properties
Produces granules with strong mechanical strength.
Improves tablet hardness and reduces friability.
Enhances dissolution profiles.
High Process Efficiency & Reproducibility
Shorter granulation cycles compared to traditional methods.
Easy to scale up from lab to production.
Consistent results reduce waste and rework.
How a High-Shear Granulator Works
A high-shear mixer granulator typically consists of a mixing bowl, an impeller, and a chopper.
Mixing: Powders are loaded into the bowl, and the impeller rapidly mixes them.
Agglomeration: A binder solution is sprayed during mixing.
Chopping: The chopper breaks up lumps to ensure uniformity.
Process parameters like impeller speed, binder amount, and mixing time are carefully controlled. Modern Pharma Mixers from manufacturers like Jianpai utilize advanced PLC systems to automate this for precision.

Comparison with Other Granulation Methods
When comparing High-Shear Granulation vs. Fluid Bed Granulation:
High-Shear (RMG): Faster processing, higher density granules, better for cohesive powders.
Fluid Bed: Better for porous granules. (Note: Jianpai also offers advanced Fluid Bed Granulators if your formulation requires drying and granulating in one step.)
While RMG equipment requires a separate drying step, its speed and densification capabilities make it the preferred choice for most tablet formulations.
While the initial investment in a high shear mixer granulator might be higher than simpler equipment, the ROI is significant:
Reduced production time and labor costs.
Lower material waste due to consistent batches.
Scalability that supports future growth.
When evaluating the high shear mixer granulator price, consider the long-term savings in efficiency. As a direct factory supplier, Jianpai offers competitive pricing for GMP-standard machines.

FAQs
Q1: What is RMG in pharma? A: RMG stands for Rapid Mixer Granulator, which is another name for a High Shear Mixer used in wet granulation.
Q2: What binders are used in high-shear granulation? A: Common binders include PVP, HPMC, and starch derivatives.
Q3: Can high-shear granulation be used for heat-sensitive drugs? A: Yes, but process parameters must be controlled. Alternatively, consider Fluid Bed Granulation for gentler processing.
Q4: How do I choose the right granulation machine? A: Consider batch size and product characteristics. Check our High Shear Mixer page for specifications.
