Briquetting machine is a mechanical equipment that compresses biomass raw material into stick fuel. It is an important part of charcoal making machine. The structure of sawdust briquetting machine is complex and delicate. Each part plays a vital role. So, what parts are the sawdust briquetting machine composed of?
Screw feeder: through motor-driven screw blades, the biomass raw material is evenly fed to the moulding chamber. The feeding speed is usually 500kg/h-2000kg/h.
Feeding hopper: the capacity is about 300L-500L. It is also equipped with anti-clogging design. This ensures a continuous and even supply of raw materials.
Electric heating device is used to preheat the mould, which greatly reduces the preheating time. The latest technology adopts PID temperature control technology.
Roller and mould: the hardness of the roller needs to reach HRC55-60. the hole diameter of the mould is often 30-50mm. the density of the finished product is 1.1-1.4g/cm³.
Forming cavity: The raw material is compressed and moulded under high temperature and pressure. The working temperature of moulding is 180-300℃.
Motor and reducer: the motor power is usually 11kw-22kw. Reduce the rotational speed and increase the torque through the gear box. Ensure the stable operation of the pressure roller.
Bearing and coupling: High temperature resistant and high load bearing is used. For example, spherical roller bearings. The service life can reach more than 5000 hours.
Intelligent control: can be equipped with PLC automation module to achieve parameter adjustment (pressure, temperature) and safeguard warning.
Protection devices: including overload protection, emergency stop button, etc.
The centralised lubrication pump injects oil into the bearings and gears at regular intervals of about 8 hours.
The cooling device adopts air-cooled or water-cooled device. Prevent the equipment from overheating and ensure the continuous salary for 8-10 hours without performance degradation.
The key parts of the whole machine (moulds, pressure rollers) are made of alloy steel or tungsten carbide spraying layer, which improves the abrasion resistance by 30-50%.
The machine frame is welded with Q235B industrial steel plate with thickness about 12mm. The thickness is about 12mm to ensure the stability of the whole machine.
Clean the raw materials in the hopper and pusher of the equipment daily. Prevent the mould from clogging.
Add lubricant every 500 hours. Check the tightness of the drive belt.
In conclusion, the performance of the briquetting machine depends on the fit of each part and the choice of material. Users can match the corresponding configuration according to the specific production requirements. At the same time pay attention to regular maintenance and prolong the life of the equipment.
Sawdust briquette machine is a kind of screw extrusion type press. Also known as: biomass ball making machine and charcoal machine. It is used to make biomass raw material into fuel-type balls. Sawdust briquette machine can take waste agricultural materi
Charcoal briquette extruder machine is also called coal stick extruder. Adopting the principle of spiral extrusion. It is a coal bar forming equipment that compresses the modulated coal powder into a prefabricated shape with a certain strength.
Bamboo charcoal has high utilisation value. In daily life, bamboo charcoal is mainly used to eliminate and adsorb odours. For example, it can be used to eliminate the odour of a new car or to eliminate the odour of a new house after renovation.
Continuous carbonization furnace can directly carbonise: sawdust, coconut shell, rice husk, bamboo shavings, straw, nut shell, coffee shell, palm shell, peanut shell, and other biomass raw materials. It is a new type of carbonization equipment.
