What is required when a sawdust briquette machine working?
In the whole charcoal production line, a sawdust briquettes extruder machine is an important machine for charcoal molding. Therefore, it is necessary to know how to make better use of the sawdust briquettes machine. To use the sawdust briquette machine must understand the requirements of the sawdust briquette machine, so as to ensure the production of high-quality machine-made charcoal.
Requirements for raw materials
The quality of the rod is not only determined by the equipment itself and the production process, but also by the moisture content in the raw material. The moisture content of raw materials is generally required to be less than 10%.
Therefore, our initial work is to dry raw materials. Before drying, the raw material can be dried in the open air for 1-2 days, so that the moisture on the surface of the raw material evaporates, reducing the drying time and fuel consumption of the dryer.
Then we will put granularity qualified raw materials into the airflow dryer machine or rotary dryer machine for drying, the moisture content of materials will be reduced to below 10% when drying, the average temperature is about 60-70 ℃. After drying, the raw material can be entered into the sawdust briquette machine to press the rod.
Requirements for temperature
The production of the rod is completed on the biomass briquette machine. There is the heating ring outside forming the sleeve of the sawdust briquettes making machine equipment, which forms the temperature of the sleeve can be increased to around 350 ℃.
The temperature of the sleeve can be adjusted. When the temperature of the sleeve is higher, the surface color of the shaped rod is darker. On the contrary, when the sleeve temperature is low, the color of the rod is lighter.

In order to ensure a smooth surface, high density, and no crack, the suitable forming temperature can be selected according to the type of raw material and moisture content. The temperature of the sleeve can be determined by field test.
Requirements for accessories
The screw propeller is an important part of the sawdust briquette machine. The size of standard steel 45 affects the forming speed and operating stability of the rod.
Therefore, when the propeller wears, to timely repair or replace the new propeller, so as not to affect the normal production. The wear-resistant electrodes must be used for maintenance. According to the helix angle layer of the propeller, welding slag must be removed before rewelding.
