Characteristics：
Model ZPW 20 Rotary Covered Tablet Press adopts a full enclosed structure. With the operation compartment isolated from the outside. The compressing compartment is wholly made of stainless steel, which is in compliance with the GMP requirement on the production of pharmaceuticals.
The machine adopts the adjustment of speed by means of frequency inversion, which is easy in operation and wide in the scope of adjustment of speed. Disinteg - rated structure is adopted for the turned, with the top of the table directly in contact with the pharmaceutical materials made of stainless steel and hardened by special technological process, resulting in the remarkable improvement in fatness and resistance to wearing.

The lubrication system of this machine can ensure the oil supply to every lubricating point, reducing the wearing of the worm - gear box and the tracks, and extending the working life of the machine.
The electrical part adopts programmable control, with multi automatic control functions such as stopping of the machine on overload, insufficiency in the core material hopper, etc. It has a double detection mechanism by phoot-eletric switch and pressrue sensor, to ensure the automatic.
Rejecting of any table without a core. This machine can be used as a normal tablet press or for the production of double layer tablets after a slight alteration. When used to produce the covered tablets, attention should be drawn to the control of the hardness and the precision of the dimension of the core tablet.

Model ZPW 20 Rotary Covered Tablet Press is also applicable in other industries such as foodstuff and chemical, in additon to the pharmaceutical Industry the need for the compression of two type of granular materials the are not to be mixed or for the protection from oxidation, control of light avoidance or delay of release of medicine.
