The crushing strength was affected by the mineral phases generated during oxidative baking and the subsequentlyformed pellet microstructures owing to CaO addition. The reduction and smelting properties of HCVTMP with different CaO additives were measured and characterized with different softeningmeltingdripping indices.

decrease was observed upto 30% and a rapid decrease was observed in between 30% 50% followed by a steady decrease upto 80% and later a slow decrease was observed. Similarly the same trend took place in case of maximum dry density values. At high percentages of crusher dust, the slow decrease in OMC and MDD was due to

Crushing is typically a dry operation that is performed in two or threestages (, primary, secondary, tertiary crushing). Lumps of runofmine ore as large as m across are reduced in the primary crushing stage to 10–20 cm in heavyduty machines. In most operations, the primary crushing schedule is the same as the mining schedule

Cone crushers are commonly used for secondary crushing (although impact crushers are sometimes used), which typically reduces material to about to 10 centimeters (1 to 4 inches). The material (throughs) from the second level of the screen bypasses the secondary crusher because it is sufficiently small for the last crushing step.
