DH Series

"DH" Series Double -Layer Rotary TabletMachines, can be proven to be reliable for :

• Bi-layer design for up to 58,000 tpm
• Single layer capable to 200,000 tpm
• Compression force to 10 tons
• For medium to large batch production;
• Allow for single layer tabletting purpose with double-sided output;
• Accurate tabletting;
• Tabletting compartment separated from drive mechanism;
• Mechanical compression system;
• Easy maintenance & cleaning ;
• Meets GMP;

Machine drive is completely separatd from the press space

Direct rotation of the turret by the main shaft reduces the noise level. The gearbox, with a casehardened nickel steel ground worm and bronze wormwheel, it provides maximum protection to the gears and the drive system.

Mechanical compression system

The design of machanical compression system can be ensured for longer production runs. Pressure rollers are made of special tool steel that ensures uniform pressure application, the double bearings are fitted,which minimize wearing of the rollers.

Cam design & lubrication

A central lubrication system supplies oil continuously to lower punches, while grease applied manually lubricates upper punches. The ejection cam is manufactured from apecial tool steel for extended life, while a double sided lifting cam is provided.

Cleaning and tool changeover

The detachable panels can be removed easily, which reveal the entire lower punch cams. This allows easy removal of the lower punches.

Upper & Lower punch seals

The scrapers seals for the upper punches protect tablets from oil drip, while the dust seals on the lowers prevent the punches from binding and reduce wear on the cam.

This combined with an efficient dust extraction system allows prolonged run with little downtime for cleaning.

Multi-Layar Tabletting Purpose

The machine is designed for double-layer tabletting purpose with single-sided output, it can also be easily converted for single layer tablet production, but with double-sided output. Both layers can be easily weight controlled respectively.

Difficult products

Although not equipped with pre-compression as standard, the "DH" series machine can be provided with special parts to allow one side of the press to be used as a pre-compression featuhes.
