The max. output refers to the quantity of pressing little tablets from ideal granular.

The max. output is designed capacity, in real production, it is related with many factors, for example, powder fluidity, characteristics, tooling, etc. Usually it will be 70% for round tablet, 50% for big tablet, which only for reference, if very strict, please make test before order.


Main Function

PLC Control, automatic tablet weight controlling system, automatic batch rejection device, auto sampling function.

Average tablet weight

Average tablet weight control

Single tablet weight tolerance





Better for round diameter ≥φ5mm

0.15g ~ 0.3g






*Tested by placebo powder

1. Color touch screen 15”, with the display of main average pressure, single punch pressure, alarm at fault, automatic stop and help menu, The on/off of tablet deduster and on/off and pulse of dust collector can be controlled by the touch screen (The tablet deduster and dust collector are optional). 

2. Six sets of servo transmission mechanism are used for adjusting main compression (tablet thickness), pre-compression and filling depth of two sides. Control system is operated through the touch screen which display the value of main compression, pre-compression, filling depth and tablet thickness.

3. Electronic record and signature in compliance with FDA21 CFR Part 11, and data management function developed by configuration software.

4. Main motor and feeder motor are adjusted with inverter, r.p.m. can be regulated continuously with upper and lower limit.

5. With function of accumulated running time, accumulated total output, accumulated qualified output and preset output. 

6. Alarm for over filling, under filling, upper and lower value of single punch pressure over limit.

7. With the function of main pressure overload protection. Auto protection facility for electric control system, main motor overload, feeder motor overload, upper and lower punches over tight, upper and lower camber installation. Emergency stop and production parameter print online.

8. Select the pull-down cam model automatically according to the tablet quality and shape, identify and alarm online (Single layer tablet).

9. Filling decrease function effected automatically via increasing tablet thickness.

10. Automatic Lubrication system. Lubrication interval can be adjusted. Under lube alarm, lubrication pressure fault alarm and auto-stop protection. Lubricating point to the upper punch body and head.


Main Structure Features

1 Four-pole supporting rigid structure, three separated compartment for compressing, adjusting and transmission, cross contamination avoided. Gas spring concealed, tempered glass windows.  Concealed pipes and lines in tablet compartment.

2 Exchangeable turret equipped with movable forklift for assembling. Upper and lower camber track assembly relatively fixed. Double lifting cam. Up track made by copper alloy, others by nonmetal material.

3 Control system and operating system are separated relatively with main body.

4 Format by main compression and pre-compression, the compression could be adjusted continuously; pressure roller with modular construction.

5 Double layer force feeder system, better for equal filling, damping rod of lower punch with the structure of ball head piston.  

6  All parts in contact with granule and tablets, such as filling system, middle turret and tablet ejection device, etc. are made of stainless steel or innocuous macromolecule material.

7 Dust collection system with big wrap angle structure, connecting diameter φ90mm.

8 Hairline surface treatment.
