Step-by-Step Guide to Operating a Small Wood Briquette Press Machine
Product Description
Raw Material Pretreatment: Laying a Solid Foundation for Molding
While pretreatment is not part of the small wood waste briquette machine's main operation, it is a prerequisite for ensuring the machine's normal functioning. The raw material needs to be crushed to a particle size of 2-8mm, removing impurities such as stones and metal. Simultaneously, the moisture content needs to be controlled to 8%-15%-too high a moisture content can lead to briquetting cracking and die blockage, while too low a moisture content results in insufficient lignin softening. Moisture content needs to be adjusted through sun-drying or using a dryer to ensure the raw material meets the briquetting machine's processing standards.
Uniform Feeding: Balancing Capacity and Stabilizing Pretreated Raw Materials
The pretreated raw materials are fed into the hopper automatically or manually. An agitator within the hopper prevents material accumulation and bridging, ensuring uniform feeding. The feeding speed must be precisely matched to the sawdust log press machine's capacity. For small models, the feeding speed is controlled at 50-100 kg/h, and for large models, it is controlled at 200-500 kg/h. Feeding too quickly can cause equipment overload and shutdown, while feeding too slowly reduces capacity and wastes energy.
Extrusion Molding: Core Operational Step
After the raw material enters the molding cavity, the small wood dust briquetting machine applies high pressure and high temperature through corresponding mechanisms to achieve densification and bonding. Screw-type extrusion relies on frictional heat generation and spiral extrusion; hydraulic extrusion uses a pressure head for pressurization and constant temperature heating; and flat extrusion uses pressure rollers and die orifices for pressing, ultimately forming the raw material into a columnar shape. Pressure and temperature must be monitored in real time during the process to ensure parameters are within the appropriate range and to avoid substandard finished products.
Cutting and Cooling: Ensuring Finished Product Quality
After the columnar material is extruded from the molding orifice, it is cut into 5-20cm blocks of fuel by a preset cutter. The cutter speed can be adjusted as needed to ensure uniform length. The temperature of the freshly formed finished product exceeds 100℃ and must be cooled to room temperature by a cooling device or naturally to prevent high-temperature moisture absorption and deterioration. After cooling, the finished product has the required density and stable strength and can be directly stored or further processed.
