Charcoal Briquette Machine Introduction
Charcoal briquettes are made of all kinds of agro-wastes and forest residues. If there are abundant biomass resource available, you can consider starting a charcoal briquette plant. Charcoal briquettes have wide application both in industrial and home use featured with high density, small volume & good combustibility. Our professional salesman can give you suggestions to choose the most suitable type.
Raw Materials & Charcoal Briquettes
The most common materials are coconut shell, sawdust, woodchips, bamboo shavings, tree bark, chestnut shell, cotton stalk, sesame stalk, corn stalk, sunflower stalk, soybean stalk, rice husk, sugarcane bagasse, corncob, etc. The material diameter must be less than 6mm and moisture is about 10%. The raw material piled density is 60-350 kg/m³, while the briquettes piled density is 1100-1400kg/m³. We can easily draw a conclusion that the briquettes density has greatly improved, so the combustion value also improves 30%-40%. After carbonization, the charcoal briquettes calorific value is 7000-8500 kilocalories. The burning time is 200 min/kg and carbon content is 75%-85%.
How to Make Charcoal Briquettes
1. Crushing the raw materials into size less than 5mm.
2. Dry the crushed materials to 8% -12%.
3. Pressing to raw material into briquette.
Charcoal Briquetting Working principle
Briquetting is a process that biomass is compressed under high pressure and high temperature. The self bonding of biomass to form a briquette involves the thermo plastic flow of the biomass. The lignin content that occurs naturally in biomass is liberated under high pressure and temperature. Lignin serves as the glue in the briquetting process, thus binding, compressing the biomass to form into high density briquettes.
