summary:
The equipment for manufacturing pellets using an extrusion rolling machine includes an extrusion strip making machine and a centrifugal rolling machine.
1. Extruder is a device that shapes soft materials (obtained by wet mixing granulator or other process methods) into long cylindrical extrusions. Our company has developed two types of extrusion equipment: screw type front extrusion strip making machine and screw type side extrusion strip making machine. The efficiency of equipment with the same specifications for front extrusion is lower than that of side extrusion, and the material temperature rise is more severe. Front extrusion has been abandoned at present. The side extrusion efficiency is high, and the material temperature rises by about 20-25 ℃ relative to room temperature. It is particularly suitable for extruding enzyme containing products and will not cause mold death due to high temperature.
2. The diameter of the pellets is determined by the extrusion orifice plate, which is easy to control and has a wide range of granulation. The centrifugal rolling machine is a device that evenly cuts the extruded round material into cylindrical small particles with the same diameter and rolls them into pellets. The extruded circular strip is cut into a length approximately equal to the diameter of the cylinder on a rolling disc, and then rolled into spherical pellets by a high-speed rotating rolling disc. The unique toothed disc has the function of polishing the ball balls at its edges. The rolling disc is composed of many special broken teeth, which are densely distributed in dots. These broken teeth are usually 1-2mm high and spaced 2-4mm apart.

Principle and Characteristics:
Among various pill making methods, the extrusion spheroidization method has become one of the current pill making methods. It has the following characteristics: (1) high production capacity and low equipment costs;
(2) It can produce spherical particles of 0.5-3mm in size, with similar diameters and small dispersion bands;
(3) After granulation, the content inside the spherical particles is uniform;
(4) The particle shape can be spherical, cylindrical, or amorphous; Easy to coat in spherical shape.
