The main structure of the rotary extrusion granulator includes the main engine, feed inlet, speed control device, transmission system, and lubrication system. The host is the core part of the granulator, consisting of components such as a cylinder, screen mesh, blade, and bearings. The feeding port is located above the main engine, the speed control device is located on the side of the main engine, and the transmission system transmits power through the main shaft to drive the main engine to rotate. The lubrication system provides lubrication for the bearings.
The working principle of the rotary extrusion granulator is to cut, compress, and extrude the material in the feeding port through a high-speed rotating blade and screen, forming particles of a certain shape and size. During the granulation process, the material undergoes repeated shearing, compression, and extrusion to gradually form particles, which are then filtered through a sieve to remove oversized particles and ultimately obtain particles that meet the requirements.
The advantages of rotary extrusion granulator include simple operation, easy cleaning, and high degree of automation. Its structural characteristics include that all particle forming parts are made of stainless steel, the rotating structure adopts three sets of straight teeth rotation in the electric motor gearbox, the body part is welded with angle steel, and the gearbox is connected to the particle forming part through flanges.
In addition, the rotary extrusion granulator is suitable for industries such as pharmaceuticals, food, chemical, and light industry. It can crush wet powder into the required particles and can also be used to crush dry powder that has been pressed into blocks into particles. Compliant with GMP standards.
