Rotary kiln belongs to building material equipment, and it can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials.. structural featuers of rotary kiln. 1. supporting device apply rolling bearing ( few with sliding bearing) to simple the bearing structure to slow down the kiln power consumption and it also improve the maintenance and inspection.
Rotary kiln is rotary forging kiln for short, which is one of building material equipment. it is divided into cement kiln, metallurgy and chemical kiln and lime kiln as per the different material treatment. cement kiln is applied to carline cement clinker, which has two types, dry-type cement production kiln and wet-type cement production.
Some types of rotary kiln. rotary kiln for active lime rotary kiln are reliable combined scale sealing. the air leakage coefficient is less than 10% using composite refractory material, to reduce radiation loss. cement rotary kiln is composed of cylinder, gears, support device, kiln liner and kiln tail sealing equipment, green cement rotary.
The cement industry has been able to achieve this by installing multistage preheater with precalciner upstream of the cement rotary kiln, which has led to transferring the preheating and calcining reaction from the kiln to the preheater and.
The feed then moves into the rotary kiln where it is superheated to approximately 1400 c to form clinker components through a process called sintering. the heat is produced from the burning of fuel in the main burner rotary kiln and in the combustion chamber with the help of preheater exhaust fans or kiln id fans. coal, natural gas, fuel oil.
The goal of this work is the study of mechanical behavior and ferrule deformability under the heat effect, for a cement plant’s rotary kiln. this study is within the scope of preventive maintenance for these kilns more specification precisely. it’s about the finite element model validation, which simulates the kiln’s elastoplastic.
