Cement calcination rotary kiln is one of key cement calcination equipment, with witch vertical kiln, wet-type rotary kiln, ordinary hollow dry-type rotary kiln, n, vertical preheater kiln, and the new dry rotary kiln that currently widely used.

Rotary kiln is a gradient of cylindrical object, and the gradient is 3 - 3.5%, with the help of the rotation of the kiln to promote stirring the material in the rotary kiln, which the materials mixed with each other and contact reaction. Coal combustion on the kiln head produces a lot of heat, and heat make the way of the flame radiation, heat convection, kiln brick (kiln skin) conduction to the material. The material depends on the slope of the kiln shell and kiln rotation in the kiln forward movement.

The rotary kiln is the most important calcining equipment in the cement industry, lime industry, metal magnesium industry and ore dressing industry. The production output of the rotary kiln to a certain extent determines the production output of the cement plant, lime plant, metal magnesium plant and beneficiation plant. Therefore, selecting excellent performance of the rotary kiln, can improve production capacity and output. Our company's production of rotary kiln with large output, good performance, reliable operation, operability and other characteristics, is a key manufacturer for large number of cement plants, lime plants, metal magnesium plants.
