Iron ore agglomeration by extrusion

Agglomeration is widely used in ferrous and non-ferrous metallurgy to prepare small-sized ores and finely ground concentrates for smelting. One of the methods of agglomeration is briquetting, which can be done with or without binders. For briquetting with binders, roll presses are usually used. An alternative to roll presses can be extrusion presses, the main advantages of which are obtaining ...
