Jun 01, 2017· For the trial, a wetprocess clinker rotary kiln was modified to process on dry basis the low grade kaolinitic clay used as raw material. The kaolinitic clay deposit was chosen through a screening based on geologic, chemical and mineralogical criteria, and a confirmation of reactivity with an experimental protocol at lab scale.
Rotary kilns for the cement industry (limestone), silica (clay), and minor amounts of other materials heated to a temperature of 1,450 °C, at which point calcination occurs forming the "clinker" that will be milled to a fine powder with other additions to the final cement product The cement kiln is the "heart" of the cement process lying midstream between the raw material preparation ...
Working temperature:400~1400°C. Silicon carbide based nonmetallic heating element. Keeps a clean environment inside the kiln. Simple to use and easy to maintain.
A typical process of manufacture consists of three stages: grinding a mixture of limestone and clay or shale to make a fine "rawmix" (see Rawmill);; heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln;; grinding the resulting clinker to make cement (see Cement mill).; In the second stage, the rawmix is fed into the kiln and gradually heated by contact with the hot ...

Rotary kilns are widely used throughout many industries to carry out various chemical reactions and physical changes in bulk solids. As all materials respond differently, rotary kilns must be designed around the exact project specifications and material characteristics at hand in order to reach an optimal processing solution.
approximately cylindrical flame. Heat transfer from this flame and the hot combustion gases that flow up the kiln dries, heats, and calcines the counterflowing lime solids. Rotary lime kilns in the pulp and paper industry range in size from 7 ft ( m) in diameter by 175 ft (53 m) long to ft (4 m) in diameter by 400 ft (122 m) long.
The rotary cement kiln belongs to building equipment such as chemical rotary kiln and active lime rotary kiln. ... hood. The fuel gets into the kiln through the head of the kiln. The waste gas will be discharged from the end of the kiln after exchanging heat with the materials. ... the clay rotary kiln now also has wide application range in the ...
