Vertical shaft kilns have among others the advantage of low investment profile and hence very suitable for small and medium scale processing of various solid minerals such as limestone and refractory. The low investment profile therefore makes it attractive in developing countries where sources of investment capital are lean. Vertical kilns however are plagued with a number of operational problems such as channeling, stratification, hanging accident, poor heat distribution among others. This work investigated the effects of burner types, firing rate and degree of draft on the vertical kiln temperature profile and hence the efficiency of the kiln. Numerous fuels such as coke, coal, gas, oil, as well as other alternative fuels are combusted using different types of burner or charging systems. Our Production capacities for Vertical Shaft Kiln vary from 70 to 500 TPD are achieved.

Working principle

Material traveling slowly in the kiln. All the material get fused here. After passing through the burning zoon the material start cooling slowly. The clinkerisation start and clinker finally comes out of the kiln.
