ZPW21 Rotary Tablet Press

This machine is designed for pressing tablets from various kinds of granular materials. As its feature, the machine can press not only round tablets but also different geometrical shape tablets, double-layer and annular tablets. The tablets may have the impressed letters on both sides. The turret carries 21 sets of movable-punches and dies. So 21 tablets will be pressed for each revolution of the turret.During operation, the depth of the filling material and the thickness of the tablets can be adjusted. The pressure for tablet pressing is set by the hydraulic drive system and a pressure gauge is attached to the system to show the pressure value. A overload protection unit is included in the system to avoid the damage of the punches and apparatus when overload occurs. The machine stops automatically.New type ZPW21A and ZPW21B is designed to meet the GMP standard. ZPW21B is an improved version of ZPW21A. Its pressing area is sealed with four polymethylmethacrylate doors to be isolated with outside environment. The parts contact the material are made of stainless steel and their surface is specially antisepticized to avoid pollution.Technique parameter: Dies (sets): 21 Max. pressure (kn): 80 Max. dia. of table (mm): 20 Max. depth of fill (mm): 18 Max. thickness of table (mm): 9 Turret speed (r/min): 12 - 36 Production capacity (pcs/h): 15,000 - 45,000 Motor (kW): 3 Overall dimensions (mm): 900 x 800 x 1,640 Net weight (kg): 1,200
