Screw extrusion dry granulation machineIt is a common powder processing equipment widely used in industries such as chemical, pharmaceutical, pesticide, and food. It is based on a special working principle, which converts powdered materials into shaped particles through pressure and extrusion. The granulator is mainly composed of a feeding system, an extrusion system, a cutting system, a discharge system, and a control system. It adopts a special extrusion screw structure to extrude powdered materials into particles of specified shape and size by adjusting the parameters of the barrel and mold. The working principle of the granulator is divided into the following steps:

　　

1. Feeding system: Pre treated and screened powdered materials are fed into the material drum through the feeding system, and the feeding speed and quantity of the materials are controlled by the feeder.

　　

2. Extrusion system: After feeding, the powdered material will be sent to the extrusion area between the screw and the mold. The screw pushes the material from the barrel to the extrusion area while rotating at high speed, and gradually forms particles of a certain shape and size through the compression and extrusion of the screw.

　　

3. Cutting system: During the extrusion process, the particles formed will be cut into the required length of particles through the holes of the mold. Usually, the cutting system can be adjusted as needed to obtain particles of different sizes.

　　

4. Discharge system: The cut particles will be discharged through the discharge system, and the discharge speed and quantity can be adjusted by the control system.

　　

The screw extrusion dry granulation machine has the following advantages:

　　

1. Simple process: Compared to wet granulation, the granulator does not require the addition of liquids or adhesives, making the process simpler and the operation more convenient.

　　

2. Cost savings: By using an extrusion dry granulation machine, waste or by-products can be reused, reducing production costs.

　　

3. High product uniformity: During the extrusion process, the material is subjected to uniform extrusion pressure, and the particle size and shape are uniform and consistent.

　　

4. High production efficiency: Due to the high-speed rotation of the screw, the extrusion dry granulation machine has a higher production capacity.

　　

The screw extrusion dry granulation machine is widely used in industries such as chemical, pharmaceutical, pesticide, and food. It is often used in the manufacture of particles, particle fillers, and particle controlled release products. At the same time, by adjusting the extrusion parameters, molds, and cutting systems, particles of different sizes and shapes can be obtained to meet the needs of different customers.
