Pharmaceutical Dry Powder Granules Making Machine

1. It adopts PLC and touch screen control, frequency converter and other systems. The speed can be adjusted freely within the specified range, and the operation is convenient and stable.

Feeding Mechanism

1. The rolling mechanism consists of two mutually horizontal pressure rollers, and the lower pressure roller can move horizontally along the slider. 2. The rolling mechanism extrudes the material conveyed by the screw feeding mechanism into a sheet of a certain thickness and feeds the sheets into the secondary granulation mechanism. 3. The material feeding action between the pressure rollers is substantially affected by the surface condition of the pressure roller (the nature of different materials, the surface of the optional pressure roller has smooth, textured or straight lines). The two scrapers scrape off the hardened agglomerates on the press rolls. 4. The pressure roller is driven by the gear motor, geared, and its rotation speed can be controlled by the inverter. 5. Through the hydraulic cylinder, the hydraulic system can maintain the preset pressing pressure to ensure the continuous and consistent rolling pressure, thus maintaining the density of the material and the stability of the sheet size. 6. In order to protect the operator and the sealing process of the rolling process, a sealing protective cover is arranged outside the rolling mechanism, and a transparent plexiglass plate is arranged in front to observe the roll forming condition of the material.

The roller has a water cooling mechanism: an external cold water source or an circulating water chiller (optional) can be used to cool the roller.

1. The secondary granulation mechanism is used to form the sheet pressed by the rolling mechanism into fine particles. The first-stage granulation is subjected to coarse crushing of the pressed material pieces, and the second-stage granulation performs fine granulation on the coarse particles after the first-stage granulation. The particle size of the granules can be determined by appropriate selection of the screen. 2. The secondary granulation mechanism is located under the protective cover. After the front fixing plate is removed, the granulating knife and the sieve net can be removed for maintenance. 3. The gap between the granulating knife and the sieve net can be adjusted by the eccentric shaft. 4. Drive the granulating knife by reducer motor. The change of production capacity is achieved by the frequency converter controlling the speed of the granulating knife.

This machine is a brand new granulating equipment independently researched and developed by our company based on domestic and foreign market demand, fully absorbing foreign advanced technology and our company's existing products. The machine has the characteristics of compact structure, simple process, good air tightness, easy adjustment, easy disassembly, cleaning and maintenance, etc. It can effectively carry out dry granulation experiments and pilot tests on materials, and provide reasonable process parameters for later batch production.
