The tablet press offers quick, easy format changes and fast cleaning. It is equipped with a vacuum deduster that removes dust from the upper and lower punching rods. It also comes with an interlock system for the side guards. It is designed to operate a minimum hours without significant maintenance.

Rotary Table Press History

Several companies have produced tablet presses throughout the years. Some of them have been automated, while others have been hand-driven. With the demand for these machines growing, the manufacturers have increased their productivity.

There are many types of rotary tablet pressing machines available. They come in basic and upgrade models. The difference between the two is the automation level and the pressing speed.

A rotary tablet press compresses powder granules into tablets. This equipment can be used to produce millions of tablets per hour. It reduces the waste of formulation and can control the hardness and weight. The machine's capacity can be increased by adding a deduster or a vacuum powder loader.

A rotary tablet compression machine must be able to provide optimal flow angles to ensure that the raw material stays flowing at the right rate. It also needs to have a vacuum driven suction unit and good ventilation. It should have a power supply that is three-phase five-wire. It can have a depth fill, which is necessary for a machine of this type.

A rotary tablet compression machine can be purchased with a touchscreen HMI system for operator control. The touchscreen allows the user to monitor the entire process from start to finish. It is possible to attach a tablet scraper to the machine.

Rotary Tablet Press Working Principle

Various rotary tablet presses are available. The models vary in pressing speed, automation level, and capacity. They are designed to reduce formulation wastage, reduce production cost, and produce high quality tablets.

These presses use a two step action to compress powder granules into tablets. In the first step, granular material is mixed and shaped into a homogeneous blend. Then, the mix is delivered to a hopper, where it is confined. Once the material is ready, it is loaded into the feeding system.

The powder then falls into the die. The upper punch moves in the die cavity to compress the material. The lower punch rises to eject the excess powder. The height of the lower punch dictates how much material is packed in the die. The height of the top and bottom punches is controlled by a metering cam.

After the fill stage, the lower punch track is adjusted to ensure proper density and volume of the granules. The feeder is then fitted with a take-off blade. The blade is able to deflect the tablet down the discharge chute.

The feeding system of the machine should be made of 316L stainless steel. This prevents the powder from sticking. The feeder also provides a constant flow of powder.

The turret is a crucial part of the tablet press. It holds several punches and helps align them. Its design determines the number of stations. A larger turret provides a faster pressing capacity. Its diameter also influences the number of punches.
