Introduction

A rotary kiln refers to a rotating calcining kiln (commonly known as a rotary kiln), which belongs to the category of building materials equipment. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to the different materials they process. Cement kilns are mainly used to calcine cement clinker, and are divided into two categories: dry-process cement kilns and wet-process cement kilns. Metallurgical chemical kilns are mainly used in the metallurgical industry for magnetization roasting of lean iron ore in steel plants; oxidation roasting of chromium and nickel iron ores; roasting of high-alumina vanadium ore in refractory plants and roasting of clinker and aluminum hydroxide in aluminum plants; and roasting of chromium ore sand and chromium ore powder and other minerals in chemical plants. Lime kilns (i.e., active lime kilns) are used to roast active lime and light-burned dolomite for use in steel plants and ferroalloy plants.

Why choose our rotary kiln?

1. High Temperature / Cleanness: Our special kiln core drum restrains oxidation and abrasion under high temperature conditions.This maintains a clean atmosphere and prevents product contamination.

2. Special atmosphere gases: Original sealing system keeps kiln airtight, allowing for heating by special atmosphere gases possible.

3. High temperature control accuracy: Original temperature measuring system makes measuring actual temperatures of materials possible, resulting in highly accurate temperature control.

Product features

It can efficiently remove moisture from materials and improve the drying efficiency of materials. It speeds up the production process.

Working principle

The material is fed into the kiln through the kiln tail (high end) chute. Due to the inclination and slow rotation of the cylinder, the material rolls along the circumference while moving axially from the kiln tail (high end) to the kiln head (low end). The material keeps rolling and moving forward in the rotary kiln. The heat source heats the rotary kiln, and the material heats up and reacts in the rotary kiln. The reacted material is discharged from the kiln head and enters the next process.
