Rotary kiln is used for calcining material‚ which belongs to building material equipment class. Rotary kiln according to different processing materials can be divided into cement kiln‚ metallurgy chemical kiln and lime kiln. The rotary kiln produced by Henan Zhengzhou mining machinery Co.‚ Ltd. is with strong structure‚ stable running‚ high quality products from the kiln‚ and we can provide users with advanced‚ efficient vertical tube of preheater‚ and five cyclones preheater.

Therefore‚ the spherical bush burning of the main bearing directly affects the normal operation of the device‚ thereby affects the processing operation of the entire production line. The spherical bush of the sliding bearings in the actual production often burns watts‚ causing great loss. (1)The main failure mode of the rotary bearing is the roll surface wear

factory. This limestone rotary kiln can produce lime with advantages of strong ability to react chemically‚ low volume density and large specific surface. At present‚ it has been one of the most preferred auxiliary equipment for steel-making‚ coking and calcium carbide industries. Moreover‚ it is also the best kiln type in limestone industries for its strong adaptability to raw and fuel materials‚ convenient maintenance and low consumption benefits. As the lime rotary kiln adopts new modern technology

Lime preheater A lime preheater is a piece of equipment used in conjunction with a limestone rotary kiln that allows the length of the kiln to be reduced while increasing the fuel efficiency of the system. The connection of the preheater to the kiln is accomplished with a transfer chute‚ which is both a duct to convey hot gasses from the kiln to the preheater and a chute to convey stone from the preheater to the kiln feed end. Metso preheaters are available in rectangular or polygon designs‚

Rotary kiln is composed of main drive system and auxiliary drive system‚ and kiln and cooler transmission system are relatively simple. Rotary kiln has two drive systems and their roles are: The main drive system are composed of main motor‚ reducer‚ gear‚ ring gear‚ and cylinder. When sufficient speed ratio and capacity of the reducer are deficient‚ you can add a semi-open gear drive between the reducer and gear ring gear‚ and a small number of kilns can be added a belt drive between the motor and

Cement rotary kiln maintenance mainly includes kiln cylinder hitting‚ split brick‚ clean up and masonry. In order to shorten the time of stoping rotary kiln‚it is commonly that kiln cylinder hitting and split brick usually is conducted after 10 or 12 hours rotary kiln cooling. The temperature inside of rotary kiln remains above 900 degree centigrade‚therefore kiln cylinder hitting and split brick is working in the condition of high temperature and high dust. As is well known‚ diesel engine driven
