A wood grinder machine—often called a wood crusher, shredder, or hammer mill log crushing machine—transforms wood waste into usable particles by combining powerful impact and controlled screening. It processes logs, branches, slabs, and other forestry residues into both fine sawdust and coarse wood chips, making it invaluable in modern wood processing.
How the Wood Grinder Works?
Inside the grinding chamber, rotating hammers and knife discs impact incoming wood, striking it repeatedly until the material breaks into smaller pieces. As particles become small enough, they pass through the mesh screen holes at the outlet. Oversized pieces remain in the chamber and are re‑crushed again. This continuous loop ensures uniformity in the final output.
Fine Output: Sawdust Production
By using smaller‑hole screens (typically 0.3–1.2 cm), a wood grinder can produce fine sawdust ideal for pellet mills, briquette presses, and applications requiring consistent powder‑like material. Fine output also serves animal bedding and absorbent uses, enhancing material utility.
Coarse Output: Wood Chips for Industrial Use
With larger screen openings and adjusted rotor speed, the same machine yields coarse wood chips for biomass boilers, charcoal production, particleboard manufacturing, and mulching. Such versatility allows producers to meet different industry requirements with one system.
Machine Structure and Key Components
A typical wood grinder includes a sturdy frame, robust motor or diesel engine, pulley, shredding chamber, knife disc, hammers, and a screen system. These parts work in harmony to deliver stable performance and consistent particle size control. Available variations include electric models, diesel‑powered units, stationary crushers, and mobile hammer mills suited to different operational settings.
Adjustable and Powerful Performance
Shuliy’s wood crusher machines offer adjustable outlet sizes from 0.3 to 1.2 cm and processing capacities ranging from 300 to 5000 kg per hour, making them adaptable to small workshops and large industrial setups alike. Operators can easily change screen size or model type to shift between fine and coarse output.
Broad Applications
Wood chips and sawdust produced by these grinders find applications across many industries. They can be raw material for wood processing plants, charcoal factories, board manufacturing, and biomass pellet production, contributing to efficient wood recycling and resource conservation.
