Production Introduction

Rotary kiln is a high-temperature treatment facility used to heat the material to high temperature through calcining in a continuous process. They can also be used in the front stages of metal extraction by roasting sulfide ores in various ways to prepare ores for smelting. Rotary kiln can be divided into cement rotary kiln, metallurgical rotary kiln and lime rotary kiln according to different processing materials. Cement rotary kiln is the main equipment of cement clinker dry process and wet process production line.

How does a rotary kiln work?

1. The raw material is fed into the kiln body from the high end of the feeder.

2. With the help of the slow rotation of the kiln, the raw material rolls in the circumferential direction of the kiln and moves from the high end to the low end along the axial direction.

3. The coal injection combustion at the kiln burner head generates a large amount of heat, which is transferred to the material through the radiation of the flame and the convection of the hot gas. The material is decomposed by heating and undergoes a chemical reaction, eventually changing its state.

4. The calcined material becomes the clinker. It is discharged from the lower end of the kiln barrel and enters the next stage.

Why Choose Zoomjo group rotary kilns?

Highly intelligent. The heating temperature, rotation speed, and axial movement of the cylinder are controllable.

High capacity with 180-10,000 tons per hour.

Designed for particularly demanding applications, from corrosive materials to harsh process environments. Three heating methods of calcination, sintering, and pyrolysis are adopted, with uniform heat distribution and low heat consumption.

Good wear resistance, bending strength and refractoriness, reliable operation, and longer service life. Low failure rate, easy installation, and maintenance.

Good sealing, equipped with a new type of dust collector to achieve zero pollution production.
