4. Group History
• 1968
– Started in a workshop of 20 sq. meter with 6 people
manufacturing punches & dies
• 1987
– Introduced Adept Tablet Press
5. Current Scenario
• Annual capacity of 30 tablet presses & 12000
tooling sets
• Export to over 35 countries
• More than 50% production exported
• Over 300 Adept Tablet Press in production at
present
6. Achievements
• Our major Innovations
– Higher Station Turrets
– R&D Turrets
– ‘A’ Tooling 59 station press
• Only Indian Tool Mfr. to be mentioned in TSM [4th
Edition] as ‘Reviewer & Contributor’
• Approved global tooling vendor for SanofiAventis
• Leading tooling exporter
11. Center Drive
• Eliminates the Worm &
Gear Ring mechanism
thereby reducing the
number of moving parts
• Gear box is directly
coupled to the center
shaft
• Keyless Power Lock
eliminates any back lash
12. Direct Pressure Design
• Pressure is applied
directly to the
compression axis
– Eliminates Cantilever
mechanism
– Also ensures uniform
pressure
13. No Chains & Sprockets
• All external control mechanism connected using
universal joints
14. Rollers Fitted with Bearing
• Does not require continuous oiling
– Eliminate possibility of roller jamming
• Special cylindrical roller bearing with High Load
capacity ensures long life
15. More Pressure
• Pre-Compression Force of 10 tons
– Useful for bigger tablets & low compressibility
product
• Rollers of double thickness
• All 8 Pre & Main Compression
Rollers are Identical
19. Hydraulic Pressure System
• Force is applied using Hydraulic Pressure
– Compression Spring is replaced by Hydraulic Power
Pack
– Doubles up as overload release
– Can be used to measure applied load in Tons
20. Quick Setup Rotary Feeder
• Rotary Feeder is fitted with overflow indicator
– Helps set Rotary Feeder Speed and prevent jamming
21. Spring Plugs for Lower Punch
• One time setting required
– No need to remove / adjust while installing lower
punches
• Reduces changeover time
22. PLC Control
• Controls

27. GMP Compliant
• Contact parts of S.S. 316
• All non-contact parts in compression zone are
Electroless Nickel Plated / Hard Chrome Plated
• S.S. fabrication done using Laser Cutting & CNC
Bending
• Lesser parts in
compression
zone
– Upper Roller
– Rotary Feeder

Editor's Notes
Hello Friends,
Today I am here to talk about the Rotary Tablet Press.
But before I begin, I must admit to you that I am not a good speaker. Hence I would prefer it to be an interactive session rather than a speech.
So at any point if you have any clarifications, questions or observations please do not hesitate to ask me right then.
What I will cover in today’s presentation are the important machine parts and what role each of them plays.
However, for the benefit of my young friends, who were not around at that time, I would like to quickly take you through the evolution of the tablet press.
In the early days, the single stroke press was manually operated and the output was about 150 tablets per hour.
Later it was motorized and the output increased to 900 tablets per hour.
And the latest in Rotary Tablet Press are electronically instrumented presses which can run at 60-90 RPM and give an output of 500,000 tablets per hour.
In fact the Korsch XL-800, 95 station press can give an output of 1,000,000 tablets per hour.
Now we will get to the main section of the presentation.
What I will do is to take you through the important parts of the Press and for every part I will try and explain its:
Function
Importance
Benefits
Setting
Inspection & Maintenance
Common problems
Recent developments
Conventional machines can be changed to higher stations to get more production. For example a 16 stations D tooling turret can be changed to a 32 station BB tooling turret. This will give double production on the same machine.
Similarly 27 station B tooling turret can be changed to 45 station BB tooling, which will give 65% more production
In the same sequence 27 station B tooling turret is changed to 59 station A tooling, which gives 120% more output.
Till date we have successfully upgraded over 200 turrets
