The ring die pellet mill produces pellet feed with high hardness, smooth surface, and tight internal structure through powerful extrusion. Its core components, the ring die and rollers, are made of special wear-resistant materials for long service life. The equipment integrates a steam conditioning system that cooks the powder before pelleting, improving starch gelatinization and feed digestibility. It offers advantages such as large output, high pellet formation rate, and low powdering rate. Modern models often use frequency conversion technology to enable stepless adjustment of ring die speed, adapting to different formulations and capacity needs.

Specifications are usually indicated by the inner diameter of the ring die, such as Model 420, 508, etc. The power range is wide, from 30kW to over 250kW. Capacity varies by model and formula, ranging from 1 to 15 tons per hour. The ring die aperture range is wide, customizable from 1.5mm (for aquatic feed) to 8mm (for ruminant feed). The number of rollers is typically 2 or 3. The equipment is usually equipped with safety pins or torque overload protection devices to protect core components under abnormal conditions.

Mainly used to produce complete pellets for poultry, pigs, cattle, and sheep. By changing ring dies with different apertures and compression ratios, it can produce pellets that meet the needs of different animal growth stages. It is also widely used in the production of aquatic feed (sinking and floating), pet food, and feed for economic animals. It is a iconic piece of equipment in modern, large-scale feed processing plants.
