Wet Rotary Kiln Basic Function In order to produce good cement clinker and reduce coal consumption, the wet rotary kiln should have the following basic functions: 1. Pulverized coal can be sprayed into the kiln in a dispersed form and at a certain speed, and the mixing of coal and air can be strengthened.

The cement kiln

The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter.

The rotary kiln consists of a tube made from steel plate, and lined with firebrick. The tube slopes slightly (1–4°) and slowly rotates on its axis at between 30 and 250 revolutions per hour. Rawmix is fed in at the upper end, and the rotation of the kiln causes it gradually to move downhill to the other end of the kiln. At the other end fuel, in the form of gas, oil, or pulverized solid fuel, is blown in through the "burner pipe", producing a large concentric flame in the lower part of the kiln tube. As material moves under the flame

Wet process rotary cement kilns: modeling and simulation

Mar 17, 2006 Currently the design of chain systems for wet process rotary cement kilns depends strongly on experience. Systematic theoretical and experimental investigations for the dimensioning of chain systems are not known. Based on a one-dimensional cell model, a simulation program for wet process rotary cement kilns with chain systems has been developed.

Wet Process of Cement Manufacturing Cement Wet Process

The wet process of cement manufacturing refers to grinding raw material into slurry after mixing with water and then feeding them into the wet process kiln for drying and calcination and finally forming clinker. The slurry’s water content is usually between 32%-36%.
