Twin Dome Granulator 60
The TDG-60 (Twin Dome Granulator) produces granules from 0.3 mm to 2.0 mm diameter with reduced die breakage risk, consistent internal fill, and a dome die matched directly to the lab-scale MG-55 for predictable scale-up.
Why TDG-60
Three design decisions that separate the TDG-60 from conventional extrusion granulators when small granule size and consistent quality matter.
Compared to the conventional TDG-80 and TDG-110, the TDG-60A uses a smaller die diameter with increased structural strength. This directly reduces the risk of die breakage when producing small-diameter granules — a common failure point in standard-size machines.
Even during small-quantity production runs, the TDG-60A maintains sufficient internal fill volume to preserve granule physical properties. Output quality does not degrade when batch sizes are reduced.
The TDG-60A uses a dome die identical in size to the lab-scale MG-55. Process parameters developed at laboratory scale transfer directly to production, reducing the scale-up risk that often delays commercialization.
Compared to conventional TDG-80, TDG-110, the die diameter is smaller and the strength is increased
Even when producing small amounts, it can maintain the internal filling amount and maintain the physical properties of granules
Reduced scale-up risk by using a dome die that is the same size as a lab scale machine (model MG-55)
Output Quality
The TDG-60 supports a broad granule diameter range. Below are representative outputs at three key sizes within the 0.3–2.0 mm operating range.

Frequently Asked Questions
Common questions from engineers and process designers evaluating the TDG-60A for small-scale granulation applications.
The TDG-60A dome die supports diameters from 0.3 mm to 2.0 mm. This extends below the 0.5 mm minimum available on the TDG-80A and TDG-110PA, making it the appropriate choice for fine granule applications where conventional machines carry elevated die breakage risk.
The TDG-60A uses a smaller dome die diameter with increased structural strength — specifically to reduce die breakage risk at small granule sizes. The TDG-80A and TDG-110PA are higher-throughput machines (100-150 kg/h and 200-300 kg/h respectively) with touch panel operation, but their conventional die design makes small-diameter production riskier.
Yes. The TDG-60A uses a dome die that is the same size as the lab-scale MG-55. Process parameters, formulations, and operating conditions developed during R&D on the MG-55 transfer directly to the TDG-60A, reducing scale-up risk and development time.
The TDG-60A dome die is available in SUS304 and SUS316 stainless steel. SUS316 offers enhanced corrosion resistance and is commonly specified for pharmaceutical, food, or chemically aggressive applications.
The TDG-60A operates on AC200V / AC400V / AC460V class, Three Phase, 50Hz/60Hz power supply. The motor rated at 1.5 kW makes it the lowest-power model in the Twin Dome Granulator range.
Yes. The TDG-60A is specifically designed to maintain internal fill volume even during small-quantity production, preserving granule physical properties. This is a known challenge with larger-format machines running at reduced capacity.
