First of all it is essential to clarify what is the tablet press machine ,which is expounded as below:
A tablet press is a mechanical device that compresses powder into tablets of uniform size and weight. A press can be used to manufacture tablets of a wide variety of materials, including pharmaceuticals,illicit drugs such as MDMA, cleaning products, and cosmetics. To form a tablet, the granulated material must be metered into a cavity formed by two punches and a die,and then the punches must be pressed together with great force to fuse the material together.
A tablet is formed by the combined pressing action of two punches and a die. In the first step of a typical operation, the bottom punch is lowered in the die creating a cavity into which the granulated feedstock is fed. The exact depth of the lower punch can be precisely controlled to meter the amount of powder that fills the cavity.
The excess is scraped from the top of the die, and the lower punch is drawn down and temporarily covered to prevent spillage.
Then, the upper punch is brought down into contact with the powder as the cover is removed.
The force of compression is delivered by high pressure compression rolls which fuse the granulated material together into a hard tablet. After compression, the lower punch is raised to eject the tablet.
An old rotary tablet press
There are 2 types of tablet presses: single-punch and rotary tablet presses. Most high speed tablet presses take the form of a rotating turret that holds any number of punches.
As they rotate around the turret, the punches come into contact with cams which control the punch's vertical position. Punches and dies are usually custom made for each application,and can be made in a wide variety of sizes, shapes, and can be customized with manufacturer codes and scoring lines to make tablets easier to break.
Depending on tablet size, shape, material, and press configuration, a typical modern press can produce from 250,000 to over 1,000,000 tablets an hour.
The tablet machine rotary tablet press machinery from GPseries is a compact type of the automatic rotation and continuous tablet press, mainly used in the technical research in pharmaceutical, chemical, food, electronic and other industries, and it is important equipment for determining whether the grain materials can be pressed into tablets.
It is applicable to pressing of grain materials available to be made into tablets (within the range of pressure of the machine) with the powder content (above 100 meshes) not more than 10%.
It is applicable to pressing of regular/irregular shape and scoring tablets.
It is not applicable to semisolid, wet grain, materials of low melting point and easily absorbs dampness and powder without stickiness.

Working Principle and Main Structures
1) Turret structure: The turret is the main operation component of the machine, consisting of the lower/upper bearing assemblies, shaft, turret, etc. XXX pairs of press dies are uniformly distributed on the circumference of the turret. The moment is transmitted through the flat pin between the turret and the shaft. The shaft is supported on the bearing, driven by the worm pair, connected with spline to drive the shaft and rotate the turret for operation.
2) Track mechanism: There are the cylindrical cam and the plane cam consisting of the upper track and the lower track, which are the path for the movement of the upper and the lower press lever.
The upper track is composed of the upper press upward track, upper press downward track, upper press upper parallel track, upper press lower parallel track, pressing down track, etc., all securely fixed on the track disc. The lower track is composed of the lower press upward track, lower press downward track and the feeding track, installed on the lower track seat.
3) Feeding adjustment device: It is located inside the machine to adjust the tablet weight. The moon-shaped feeding track which can be seen on the machine plane adjusts the feeding amount with its rise or fall at the action of the screw.
The amount decreases when turning the round disc in clockwise direction and increases in counterclockwise direction.
4) Tablet thickness (pressure) adjustment device: The tablet thickness (pressure) is adjusted by means of adjusting the lower pressing wheel upward/downward. The lower pressing wheel is installed inside the machine, buckled on the eccentric shaft and its outside end connected on the hand wheel. When the outside hand wheel is adjusted, the eccentric shaft drives the pressing wheel to rise or fall, and adjust the tablet thickness (pressure) and further control the tablet thickness and hardness.
The upper pressing wheel upward/downward adjustment can also be used as adjustment device, but generally not used.
5) Feeding device: It is composed of the feeding bucket, adjustment bolt, the feeder, etc.
The feeder is a moon-shaped grille feeder, installed on the turret. The space between the feeder and the turret operating surface and the height of the bucket shall be adjusted based on the grain flow rate.
6) Transmission device: It is composed of the motor, synchronous belt and worm reducer, commissioning handwheel, etc.
The motor is installed on the motor seat of the base plate. When it is started, the power is transmitted via a pair of belts to the reducer worm pair, and the motor rotation speed is adjusted through the AC frequency conversion stepless speed adjustment. When opening the two sides or the back door, these components can be directly observed and contacted.
7) Shell: The machine shell is a full-closed type, and conforms to GMP standard.
The upper part is enclosed with 4 glass windows, to facilitate cleaning and maintenance.
