GZPK720 Double sided automatic tablet compression machine with pre pressure up to 100KN for Pharmaceuticals

This is a type of fully automatic and smart rotary tablet press with high speed. the GZPK720 is the ideal solution for the production of high unit quantities of mono-layer and bi-layer tablets. It is with two compression force stations for best performance.  The machine has the servo motors for the adjustment of the pressure rollers and three optional functions: ejection force display, measuring force display and upper punches running resistance display.

● Pressure is measured directly by force transducer.

● Main pressure roller and Pre-pressure roller are same dimension that can be used interchangeably.

● Both main pressure wheel and Pre-pressure wheel are adjusted by synchronous motors for a fast adjustment high precision.

● Force feeder consists of three paddle double-layer impellers with central feeding.

● All filling rails curves adopt cosine curves, and lubricating points are added to ensure the service life of guide rails. It also reduces the wear of punches and noise.

● All cams and guide rails are processed by CNC Center which guarantee high precision.

● Filling rail adopt the function of number setting. If the guide rail is not installed correctly, the equipment has an alarm function; different tracks have different position protection.

● Frequently disassembled parts around the platform and feeder are all hand-tightened and without tools. This is easy to disassemble, easy to clean and maintain.

● The measuring mechanism uses servo motor to drive the worm gear pair for move up and down by fast speed and high precision.

● The dust collection mechanism is designed with a five-layer building block structure to ensure the dust suction mechanism can be cleaned thoroughly and that the product has no risk of contamination.

● Fully automatic and no hand-wheels control, the main machine is separated from the electric control system, which guarantee machine for a life time working.

● Lower punch damping adopts permanent magnetic damping, the lower punch and the damping pin are not in contact, prolonging the service life of the l punch, and ensuring the consistency of the lower punch damping, avoiding the jump and freedom of the lower punch under high-speed operation The drop punch reduces the noise during operation.

● The middle turret material is 2Cr13, the surface hardness can reach above HRC55. It has good hardness, wear resistance and corrosion resistance.

● The upper and lower turret material is QT600, and the surface is coated with Ni phosphorus to prevent rust; it has good wear resistance and lubricity.

● Corrosion-resistant treatment for material contact parts.
