Specifications

High-tech coal natural gas based energy saving mini kiln

Introduction

1. Rotary kiln have the highest quality, with the widest range of stone feed size. 

2. Rotary kiln can use gas, oil or coal for firing. We designs for single line plants up to 1,800 tpd.

Application 

Rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. Materials produced using rotary kilns include:

*Cement, *Lime, *Refractories, *Metakaolin, *Titanium dioxide, *Alumina, *Vermiculite, *Iron ore pellets, *Zinc ore pellets.

Workingb Principle 

Modern plants are composed of 3 key components to acheive high effiency: Cooler, Kiln, and Preheater.

The basic components of a calcination rotary kiln are the shell, the refractory lining, support tyres and rollers, drive gear and internal heat exchangers.

The calcination rotary kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down towards the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or "firing pipe") which acts like a large bunsen burner. The fuel for this may be gas, oil or pulverized coal.

Features and Advantages 

1. High capacity:150-1000t/d

2. Low heat consumption 20%

3. Excellent clinker quality and stable operation

4. Lower SOx and NOx emissions.

5. Operates on a variety of fuels.

6. Control system for entire facility

7. Wide range of stone feed sizes.
