The shaft refers to a vertical vessel where the calcining takes place. Because of the weight of the bed of material in the shaft, there are limits on the size and strength of the type of limestone that can be calcined. Vertical kilns work on a batch-type system rather than continuous feed, and the upper kiln area is used for preheating.

Ore carried by a belt conveyor is deposited into a charging hopper 1 at the top of the shaft kiln from which the ore is permitted to fall into an upper external portion of a shaft 3 via a charging mechanism 2. The material thus loaded into the shaft is preheated while descending through a preheating zone 11 by ascending hot gas.

The behaviour of feed during preheating in separate shaft kiln is still poorly known in smelting. This research is aimed at understanding optimal operating conditions/steps that could be suitable for using preheating technology when lump ore is used in the feed mix. This is also one of the goals of the EU- funded PreMa project.
sintering fine ore mixed with coke breeze, a fuel which generates combustion heat. Three systems are used for indurating pellets, i.e., a shaft furnace system, a straight grate system and a grate-kiln-cooler system. Shaft furnaces are the most traditional facilities; however, few plants use this
