Description

Tablet press

Technical Field

The utility model relates to the technical field of tablet presses, in particular to a tablet press.

Background

Tabletting is a dry forming process, in which the raw material powder used for forming is completely dried or has a certain humidity, and is pressed into a sheet or ring shape by a tablet press. The powder is placed in a mold during molding, and a molding agent such as graphite is usually added to facilitate demolding and adjustment of the pore structure. The method has the advantages of being capable of adjusting the pressure of the forming machine and easily preparing the catalyst with required strength. The particles are of regular shape and high strength, and are particularly advantageous for high pressure or high flow rate reactions. When tabletting, the powders are mainly combined by Van der Waals force. Capillary pressure also increases the bonding capacity in the presence of water. When the molding pressure is not too high, the pore structure and the specific surface change. When the pressure is too great, the chemical structure is often changed in addition to the physical structure change, thereby affecting the catalyst activity.

The tablet press mechanism of installation on the milling machine can carry out the preforming to the material and handle, but can't realize the rapid cooling to the sheet material, influences crushing efficiency, and then influences the crocus quality of milling machine, consequently, need improve.
