A wood crusher is a mechanical equipment used to crush wood, branches and other wood products into small pieces or powder. The principle is to use high-speed rotating blades to break wood, and then screen the broken materials through a screen to obtain wood powder of different sizes. The wood crusher adopts a fully enclosed structure, and the dust and noise generated during the crushing process are effectively controlled, which is beneficial to energy conservation and environmental protection. Wood crushers can crush wood of various hardnesses, such as pine, fir, birch, etc. , and are widely used in construction, furniture, papermaking and other fields.
