Process description:
Crushing process: Use crusher to get the 3-5mm coal fine powders. Commonly the combined crusher/drum crusher is the best choice, it has low noise and fly ash, which is good for operators’ health.
Drying process: Before briquetting process, the materials water content should not be high, so here we need one drying machine to reduce the water content.
Mixing process: In this process, some binders will be added to the materials according to required briquetting technology. Twin-shaft mixers are the common ones for users.
Pre-pressing process: To get the high density coal briquettes and increase the working efficiency, one pre-pressing machine has the function of pre-compaction.
Formal pressing process: It is the main process in the whole line, according to briquette shape, size and hardness datas, the suitable roller press model will be recommend by our professional engineers.
Drying briquettes process: It is to dry the finished coal briquettes into the lower level for sale directly. Chain plate dryer and mesh belt dryer can be chosen according to customers’ budget.
