Product Application

Pharmaceutical Industry: Manufacturing tablets such as painkillers, vitamins, or dietary supplements.

Chemical Industry: Producing tablets or discs for industrial applications, such as chemical agents and detergents.

Food Industry: Tablet pressing for nutritional tablets, powdered supplements, or specialized food additives.

Product Feature

1

The outer casing is a closed form of all stainless steel, and the internal table surface is made of stainless steel, which can maintain the surface gloss and prevent cross-contamination, and meet the requirements of GMP.
2

It is equipped with plexiglass see-through window, which can visualize the pressing state, and the side panels can be fully opened, which is easy for internal cleaning and maintenance.
3

All controllers and operating parts are reasonably arranged.
4

The frequency conversion speed control device is used for electrical speed control, which is convenient to operate, stable in rotation, safe and accurate.
5

Equipped with overload protection device, when the pressure is overloaded, it can automatically stop.
6

Implement electromechanical integration, using touch keys and screen display.
7

Take the lead in trying the semi-automatic lubrication device and the plexiglass dust-proof device on the top of the turntable.
8

The transmission system is sealed in the oil tank under the main engine. It is a safe and separated independent part without mutual contamination. It also makes the transmission part immersed in the oil pool, which is easy to dissipate heat and wear.
9

Equipped with a powder suction device, which can suck the dust in the pressing room.
10

The wearing parts such as the upper rail, feeder, hopper, transmission worm, powder meter, etc. have a common structure with ZP33 products, which is conducive to standardization, generalization and serialization. Select forced feeding device according to poor liquidity of raw material.

Discharge Port

The discharge port is located on the machine's side and is designed to efficiently release completed tablets from the mold into a collection container. Its smooth and precise design ensures the tablets exit without breakage or blockages during high-speed operation. Easy to clean and maintain, the discharge port adheres to GMP standards, promoting hygiene and minimizing contamination risks in production.

Punch Dies

The machine is equipped with multiple punch dies, consisting of upper, middle, and lower punches that are evenly arranged around the rotating turret. These dies play a critical role in tablet formation by facilitating filling, compression, and ejection. The high-quality material of the punch dies ensures durability, precision, and consistent tablet quality. Proper inspection and maintenance of the dies are essential to ensure optimal performance and prevent production downtime.

More Details

Tablet Pressing Station

The tablet pressing station refers to the points where the punch dies undergo their key operations: filling, compression, and tablet ejection. Each station operates in sequence as the turret rotates, allowing for simultaneous and continuous tablet production. The multi-station design significantly enhances productivity while maintaining uniform tablet quality.

Pressure Adjustment

The machine offers adjustable compression pressure, with a maximum capacity of 60 kN (kilonewtons). Proper pressure settings are essential to ensure tablets achieve the desired density, hardness, and uniformity. Overly high pressure can cause tablet breakage, while insufficient pressure may lead to loose or incomplete tablets. Operators can adjust the pressure based on material characteristics and tablet requirements, ensuring consistent quality across batches.

More Details

Rotary Tablet Compression

The machine employs a rotary mechanism with multiple punches mounted on a rotating turret. As the turret rotates, the punches move along a guided cam track to perform sequential operations—filling, compressing, and ejecting tablets. This rotary system enables continuous, high-efficiency production, making it ideal for large-scale manufacturing. The rotary tablet compression process ensures low vibration, reduced noise, and stable performance while maintaining consistent tablet size and quality. Regular monitoring and maintenance of the turret system are essential to ensure long-term smooth operation.
