Vertical Ring Die Sawdust Pellet Mill - Overview

The Vertical Ring Die Sawdust Pellet Mill is a high - efficiency, energy - saving biomass pelletizing device optimized for processing sawdust and various woody biomass materials. It is featuring a vertical feeding and pressing structure, which is ideal for industrial - scale production of wood pellets for fuel, animal bedding, and other applications.

Core Definition & Application

It is a specialized machine that compresses sawdust, wood shavings, wood chips, and other woody residues (with moisture content 12% - 15% and particle size ≤8mm) into dense cylindrical pellets (6-10mm in diameter, 1-3cm in length) through high - pressure extrusion. The lignin in the wood acts as a natural binder during the process, eliminating the need for additional additives.

Its main applications include:

Biomass fuel: Used in power plants, boilers, and household heating.

Animal husbandry: Serving as high - density feed pellets or bedding materials.

Industrial processing: Recycling wood waste in wood factories and furniture workshops.

Working Principle

Feeding: Raw materials enter the pressing chamber vertically from the top by gravity, avoiding material arching and ensuring even feeding.

Pressing: The fixed vertical ring die cooperates with 2-3 rotating rollers. The rollers apply strong centrifugal and extrusion pressure to force the material through the die holes for forming.

Cutting: An adjustable frequency - conversion cutting device trims the pellets to the required length, with a high pelletizing rate.

Discharging: Pellets are discharged from the bottom, and the vertical structure facilitates heat dissipation and dust collection.

Main Data

Structural Highlights

Vertical Ring Die Design: The fixed die and rotating rollers ensure uniform material stress and high pellet density.

Automatic Lubrication: The hydraulic lubrication system automatically injects and filters oil, guaranteeing long - term stable operation.

Frequency - Conversion Cutting: It can adjust the pellet length flexibly to meet diverse customer needs.

Safety Protection: Equipped with overload protection and emergency stop functions to prevent equipment damage.

Why It Stands Out

Compared with traditional pellet mills, it has better material flow, lower failure rates, and easier maintenance. It is especially suitable for processing low - adhesion materials such as sawdust and rice husks, making it a cost - effective choice for medium - large pellet production lines.
