v118n1a10 Manufacturing and testing of briquettes from

Although binderless briquetting is the most economical form of briquetting, use of a binder becomes necessary when briquetting inertinite-rich, low-grade coals (England, 2000; Mangena, 2001; Woods et al., 1963). A binder functions as a coherent or adhesive medium between the fine coal particles, Get price
