The wet granulator uses the crystallization water in the material to directly form the powder into a new device for granules. It is widely used in granulation in the pharmaceutical, food, chemical and other industries, especially for granulation of materials that cannot be solved by wet methods. And the accuracy of the temperature control instrument is required to cooperate with the system. The wet granulator makes the fluctuation stability of the whole host temperature control system reach the extrusion temperature requirements of various plastics.
Many wet granulator power systems use V-belt and pulley drive (low cost), resulting in insufficient agitation power during long-term production, and easy to slip. The use of timing belt and timing belt drive ensures long-term manufacturing. Powerful, more able to ensure production requirements. Our company's equipment uses foreign imported or domestic high-quality synchronous belt synchronous wheel (models such as parts list) transmission, can provide full power, design parameters for 8 years without replacement. In the process of granulation, the rotation speed requirements of the mixing blades are different in different time periods. Only the two-speed motor can not meet the production requirements. The wet granulator adopts the inverter control to meet the production process and can achieve good results. Granulation effect. Our company's mixing paddles are controlled by French Schneider's frequency converter, which can guarantee the production of different kinds of Chinese medicine and western medicine.
During the working process of the wet granulator , its temperature must be controlled. Once the temperature changes, the finished product will also change. The main temperature control of the mainframe is the insulation of the wire and cable and the plastic extrusion of the sheath is based on the thermoplastic. The deformation characteristics are made in a viscous flow state. In addition to the external heating of the screw and barrel, the wet granulator is passed to the plastic to melt and extrude. The plastic granulator is also required to heat the plastic when it is extruded from the screw. Therefore, the temperature of the plastic granulator main unit should be from the whole. To consider, it is necessary to consider the heating and heating of the heater, and also consider the factors of the extrusion heat of the screw to cool, and have effective cooling facilities. The wet granulator requires correct and reasonable determination of the position and installation method of the thermocouple of the plastic granulator, and can accurately reflect the actual temperature of each section of the main unit from the temperature meter reading.
