The die is a tablet press die for pressing tablets. The working end faces of the up™per and lower punches form the surface shape of the tablet. The diameter of the middle die is thΩe diameter of the tablet. The die is the main working element of the ta≈blet press. Usually, a pair of dies includes three p®arts: upper die, middle die and lower die. The structure of the upper and lower dσies is similar, and the punch diameter is also equal. The punch diameter of the upper >and lower dies is matched with the die hole of the≥ middle die, and can slide up and down freely in theδ middle die hole, but there is no gap that can leak powder. According to the struβctural shape of the die, it can be divided into circular and speci§al shapes (including polygonal and curved shapes). The shape of the end face of the pun£ch includes plane, bevel, shallow concave, deep concave and comprehensive shape. Thγe plane and bevel punches are used to press flat cylindrical tablets, the shalloσw concave is used to press double convex tablets, the deep concave is mainly used to press ≥chips of coated tablets, and the comprehensive shape is mainly ↓used to press special-shaped tablets. In order to faciliφtate the identification and taking of drugs, the drug n≤ame, dose and vertical and horizontal lines can also be engraved on the end face of the die. Pressing different doses of tablets₽, should choose the appropriate size of the die. The working process of the tablet pre≠ss The working process of the tablet press can be divided into the following steps: 1. The pun≤ch part of the down punch (its working position is upw♠ard) extends into the middle die hole from the lower end of the middle die hole to seal the bo↔ttom of the middle die hole; 4. Upward punch and lifβt out of the hole. The downward punch rises to push the tablets out of the middle die hole λto complete a tabletting process. 5. Down to the original po≈sition to prepare for the next filling.

Development history of tablet press

The working principle of the catalyst tablet press is mainly based on powder compaction techno♠logy. By the action of high pressure, the catalyst raw material powder is &filled into a mold, and a solid tablet having a certain shape and hardness is formed throug↕h a pressing process. In this process, the tablet press adjus♦ts parameters such as pressure, speed and time through a precise control system to ensure the uniformity and stability of the pressed catalyst tablets.

Catalyst tablet press efficient production weapon for chemical iβndustry

Catalyst tablet press, as an important equipment in the field of modern chemical industry, is speεcially used to compress catalyst raw material powder undαer high pressure to form catalyst tablets in solid shape. This equipment n±ot only improves the production efficiency of the catalyst, but also has a profou₹nd impact on the production efficiency and environmental protecti§on of the entire chemical industry.

This kind of equipment is widely used in pharmaceutical, chem¥ical, food and other industries, and has become an important tool to improve production e"fficiency and ensure product quality.

Three-layer tablet press high-performance powder mateΩrial pressing equipment

The three-layer tablet press is mainly composed of upper and lower tablet wheels, intermediate∑ conveyor belts, and related metering, feeding and driving ÷systems. During operation, the material is fed through an intermediate conveyor belt to be compressed between two tabletting wheels to form tablets or ₽granules. The equipment adopts modular design, which is easy to install, debug and m₹aintain. At the same time, it is equipped with advanced PLC programmable® control system to realize automatic production.
