AGGLOMERATION AND PREREDUCTION OF ORES

Agglomeration is a process of size ,enlargement; btiquetteing,, sintering and pelletising being the three common processes used in the metallurgical industries The requirement of particle size for sintering is much coarser (generally upto 10 mm) against that of pelletising which is generally below 01 mm The briquetting process can accommodate the size range of both sintering and pelletising1/1/2012· Pelletizing differs from other agglomeration techniques in that the powdered ore is first formed into a “green” pellet or ball, which is then dried and hardened in a separate step, usually by heating Green pellets are made by combining moist ore with a binder and rolling it into balls using either a pelletizing disk or a pelletizing drum The green pellets are then dried, preheated, andPelletization an overview | ScienceDirect Topics
