Making sawdust bricks is an efficient way to utilize wood waste, helping to reduce environmental pollution and providing renewable energy. Through the use of a sawdust briquette making machine, sawdust or wood chips can be pressed into strong bricks for heating and other industrial applications. Its manufacturing process is as below:

1. Preparation of raw materials

Firstly, dry sawdust or wood chips need to be prepared as raw material. These wood chips can be waste from carpentry shops or wood processing plants.

2. Crush wood waste

Put the raw wood chips into the wood pulverizer to pulverize them into fine particles for subsequent processing. The final product size should be 3-5mm.
