Charcoal briquette machine, also called charcoal machine, its can be divided into sawdust briquetting machine, rice husk briquette machine, sawdust briquette machine, the device is the main mechanism of charcoal production molding equipment. It will make moisture 12% of bamboo, wood, shell, straw (except rice straw, wheat straw) and other granular (length ≤ 5mm, diameter ≤ 3mm) waste, without any binder, after high-temperature, high-pressure process, squeezed into the center hole with a solid salary stick.
The mechanical strength of coal briquette refers to the strength of the formation of globular products for powder materials suppressed bycoal briquette press machine and other equipment, general in the production process can add a certain amount of water and binder to ensure coal strength achieves the function of not easy to broken and for the long-distance transportation. If using biomass as the binder for coal briquette production, the heat treatment time, concentration of alkali liquor in the process of binder preparation, and the pressure size in the process of coal forming, will ultimately affect the mechanical strength of coal briquette. Therefore, how to balance these factors, to ensure that the mechanical strength of coal briquette keep in the best range, realizing mass with high quality production?
After long-term research and experiment, China Fote Machinery finally got the ideal result. Heat treatment time is the main factor influencing the mechanical strength of coal briquette products, followed by alkali concentration and the molding pressure. When the heat treatment time is 3 hours, the alkali liquor quality score is 4%, molding pressure for 28 MPa, the mechanical strength of coal briquette to achieve the best.The product design is reasonable, good quality, reliable, has a simple structure, convenient operation, small footprint, labor, energy saving features.
