Ring die pellet machine Introduction
A ring die pellet machine is a professional feed and biomass processing machine primarily used to process powdered or granular raw materials into uniform, dense pellets. Its core structure consists of a ring die, a pressure roller, a transmission system, and a motor. The rotation of the ring die drives the pressure roller to squeeze the raw materials into pellets. Ring die pellet machines are widely used in livestock and poultry feed processing, forage pellets, wood chip pellets, and biomass fuel, and are an indispensable core equipment in modern pellet production line.

Operating Principle of a Ring Die Pellet Machine
The working principle of the Ring die pellet machine is mainly “extrusion molding”. After the powdered raw materials are mixed evenly, they are fed into the ring mold through the feeding system. Under the action of the ring die at high speed, the pressing roller applies pressure to the raw material, extruded through the ring die hole, and compacted under high temperature and high pressure to form particles with smooth surface and uniform density. During this process, the close coordination between the ring mold and the press roller and the control of the moisture content and formula ratio of the raw materials are the key factors that determine the quality of the particles.
