Working principle of pelletizer

The working principle of the granulator is mainly to make powder or granular raw materials into particles of a specified shape and size through the action of mechanical force and pressure.

Granulation machines are an important industrial equipment and are widely used in pharmaceutical, food, chemical, pesticide and other industries. Its working principle is mainly to make powder or granular raw materials into particles of a specified shape and size through the action of mechanical force and pressure. The granulator mainly includes two parts, namely the hopper and the extruder. The hopper is the first part of the granulator, and its function is to put raw materials into the machine for processing. The size and shape of the hopper are determined according to the properties of the raw materials and the processing amount. The extruder is the second part of the granulator, and its function is to extrude the raw materials so that they can form particles through the mold. The extruder is usually composed of a screw, a barrel, a hopper, a head and a mold. During the extrusion process, the raw materials are subject to high temperature and high pressure, causing physical or chemical changes to form particles with a certain density and strength
