Rotary Kiln for Cement Production Plant

Introduction

Cement Kiln is mainly used for calcinating clinker and it has dry type and wet type. Metullurgical and chemical kiln is mainly used for poor iron ore magnetization calcination, the oxidizing calcination of chromium ore, ferronickel ore; the calcination of high aluminum bauxite ore in the refractory material factory and aluminum hydroxide, the clinker, aluminum hydroxide calcination in the aluminum plant; the calcination of chrome ore and chrome powder in the chemical plant, etc. Active-lime kiln is used for the calcination of active-lime and dolomite in the steel making factory and iron alloy factory.

Working Principle

Material is fed into kiln though end of kiln (higher side of cylinder). Because cylinder is inclined and it rotates slowly, material moves along with circle as well as axial direction (from higher side to lower side). After going through physical and chemical change, material gets into cooling machine through head cover of kiln after the finishing calcination. Fuel is fed into the kiln head through the kiln head, and exhaust gas will discharge at the end of kiln after exchanging heat with material.
