The wet material made by the wet mixing granulation mechanism is manually or fed into the feeding hopper of the extruder by a feeder. The multi head spiral double rod rotates relative to each other to uniformly push the wet material from the feeding end to the radial end of the extruder in the spiral direction. When it encounters resistance at the mesh plate, the pressure inside the mesh plate increases, forming an extrusion force towards the outside of the mesh plate. The material is uniformly and tightly extruded through the small holes, forming a micro cylindrical strip. Then, the next process produces spherical pellets.

Characteristics of extruder

1. The unique dual cooling system can cool the extrusion screw and extrusion orifice plate, ensuring that the material does not produce heat and remains unchanged during the extrusion process. It is suitable for fast and efficient extrusion of heat sensitive materials.

2. Uniform extrusion, good density, and high yield of finished products.

3. Continuous operation, high production efficiency.

4. The disassembly, installation, and cleaning of the extrusion screw are extremely convenient;

5. The spherical extrusion method is a structure with uniform force distribution in the screw extrusion method, and the gap uniformity between the extrusion orifice plate and the extrusion head is designed to be 1mm equidistant.

6. Compared to other screw extrusion methods, this structure has a shorter feeding and extrusion stroke, a lower extrusion pressure on the arc-shaped extrusion head, and the smaller the orifice plate thickness, the more adjustable it can be. Therefore, the heat generation during the extrusion process is low;

7. The orifice plate is formed by a mold in one go, and the extrusion holes are precisely drilled by laser, resulting in high uniformity of the particles produced.

8. The standard configuration includes a 1.0mm orifice plate, and various specifications of spherical orifice plates (0.3mm, 0.4mm, 0.6mm, 0.8mm) are available for selection, which can be used to prepare particles of different sizes.
