vertical shaft kiln - ME Mining Machinery

The multi-fuel-fired normal shaft kiln (NSK) is one of the oldest types of lime shaft kiln. This kiln type is used in the lime industry in order to manufacture so-called medium to hard-burnt lime.

From the two tables it can be seen that blast furnaces are the biggest one in size and max. outflow. However, the outflow in relation to cross section is only a little bit larger than that of normal shaft kilns.

Shaft kiln. In a shaft kiln, raw material moves counter flow to hot gas in the shaft. This gives shaft kilns the lowest fuel consumption of any type of kiln. The shaft refers to a vertical vessel where the firing 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 raw ...

This article presents a mathematical process model to simulate the limestone calcination in a normal shaft kiln. The process model comprises a set of ordinary differential equations derived from the principle of mass and energy balance, coupled with

Analysis of calcination parameters and the temperature ...

As shown in Figure 1, a vertical shaft kiln is a refractory-lined tower fitted with peripheral fuel burners and air inlets in the lower section, and gas exhaust ports in the upper.Material to be processed is introduced at the top and discharged through the base so that gases and solids are in countercurrent flow and some preheating occurs at the top section.

The principle of the PFR kiln, i.e., the calcination of lime in one shaft and the preheating of the stone with the hot kiln gas in the other shaft, is also used in the Finelime ® kiln. Thus its heat consumption is significantly lower compared to rotary kilns. Since 1989, when it was first introduced onto the market,
