A PROCESS FOR MANUFACTURING OF BRIQUETTES FROM FERRO MANGANESE OR SILICO MANGANESE FINES

摘要

The present invention relates to a process for manufacturing of briquettes from ferro manganese and silico manganese fines of 0-10 mm preferably 0-3mm size, by using selectively resol type Phenol formaldehyde as binder for the first time for making briquettes wherein Quantity of resin and mixing sequence had been suitably formulated to have good quality briquettes. Advantageously, plastic clay is also used as an additive in the process of briquette making to impart plasticity/ workability to the mix of FeMn/SiMn fines with binder which is very much non-plastic in nature, in order to form briquettes by applying pressure in briquetting machine. The maximum strength obtained after oven drying for the briquettes made with resin binder, indicated many fold increase in strength from 49kg/cm2 for green briquette to 102kg/cm2 for oven dried briquettes with maximum retention under drop test obtained for resin-bonded briquettes making it suitable for advantageous application in iron and steel making.[IN-KOL-2012-01261A]
