1)The speed is controlled by frequency converting motor. The synchronous belt wheel drives worm and turbine and last turntable. The turntable will then drive 35 punching dies to rotate clockwise. Every die feed and fill materials, press and discharge tablets through the upper and lower tracks, pressing wheels and other structures.
2)Pressure, filling, tablet thickness and rotating speed are all adjustable. All adjusting handwheels are installed on the façade of the machine and instructions can be shown on the operation panel. Operation is simple and maintenance is convenient.
3)The driving structure is absolutely separated from tablet pressing chamber for tablets’ meeting requirements of GMP. The tablet pressing chamber is separated with other parts with non-toxic and anti-corrosive stainless steel board. It is also sealed to avoid cross contamination.
4)The upper pressing wheel is equipped with unloading device for pressure adjustment. When operation pressure of the punching rod is larger than the set pressure, the rod can unload through spring compression and a buzzer will give out audio-visual signal. The machine will also stop immediately to protect parts.
5)The driving system applies worm and turbine which are separated and immerse in lubricating oil so that their service life is extended.
6)Upper track, driving worm, material hopper, material feeder and filling track are all interchangeable with those of ZP33. The punching dies of this machine conform to standard of JB20022-2004 and are interchangeable with those of ZP33/19.
7)The two side boards and rear boards are opened with special keys for convenient machine maintenance.

Principle of tablet press
1)Dosage control
For different tablets, dosage is different. Dosage is adjusted through punchers of variable diameter. After punching die size is selected, slight dosage adjustment can be done. The lower puncher can stretch into the central die hole so that the actual length of central die hole can be changed, as well as volume of medicine in the hole. Therefore, a structure to adjust the original position of lower puncher in die hole should be equipped for dosage adjustment.
2)Tablet thickness and hardness control
Medicine dosage is prescribed by prescription and pharmacopeia. To meet requirements on transport, storage and disintegration time, pressure for tablet press is demanded. The pressure will affect actual tablet thickness and appearance, so pressure control is essential. The pressure can be controlled through downward stretch of the upper puncher in die hole. For some tablet press, not only an upper puncher can stretch downwards, but also a lower puncher stretch upwards. Both of the punchers move relatively to finish tablet pressing. However, pressure is generally controlled through downward stretch of upper puncher.
