Produces various round tablets and irregular tablets.
The transparent glass doors and windows allow for clear observation of the tableting process, and the side panels can be fully opened for easy cleaning and maintenance. The outer shell is fully enclosed and made of stainless steel, and the internal table is made of stainless steel to maintain surface gloss and prevent cross contamination, meeting GMP requirements.
All controls and operating elements are rationally arranged.
The frequency conversion speed regulation device is used for electrical speed regulation, which is easy to operate, rotates smoothly, safely and accurately.
The transmission system is enclosed in the oil tank below the main body of the machine. It is a completely separated independent department and will not generate oil pollution. The transmission parts are immersed in the oil pool, which is easy to dissipate heat and wear-resistant.
Equipped with a dust collector, this advanced device can automatically remove dust.
The machine's easily worn parts, such as the upper rail, feeder, hopper, drive worm, and powder meter, share a common structure with the older ZP33 model, facilitating standardization, generalization, and serialization. The punching die is compatible with the ZP17, ZP27, and ZP33D tablet presses.
