Notes of Rotary Kiln Installation & Operation
Well understand rotary kiln design drawing
Understand the capacity, rotating speed, no. of supports, thrust roller type, rotary kiln shell erection inclination, rotary kiln shell diameter, length, segments of kiln shell, weight of the kiln shell with max. length, installing position of kiln shell with max. segment, the weight of belt with max. dimension, the weight of the belt of last belt at kiln tail, the weight of each thrust roller group and shell connecting type, etc. via rotary kiln drawing. Understand and grasp the detailed position of each thrust roller group and support roller group and the standard of basic line drawing and the position of each belt of thrust roller in cooling status via rotary kiln process drawing. Understand and grasp the layout of various workshops, offices, water, electricity and road and stacking area of rotary kiln equipment, etc. via layout drawing so that the transportation route, assembly site and the position of site tool room and the position of site temporary power, etc. can be confirmed.
Draw up testing method via erection instruction and relevant acceptance rules, prepare testing tool and instrument
Draw up testing method and prepare testing tool and instrument via testing requirement and content of rotary kiln equipment
Draw up testing method and prepare testing tool and instrument via correct technical requirement and content of rotary kiln equipment via erection process
According to the requirement of construction period and the technical force, equipment capacity of construction enterprise, main content of rotary kiln construction solution is as follows:
Introduce the model, type, performance, maximum outline dimension, weight, installed position, position of spare part yard, relative dimension of rotary kiln foundation and related condition of construction site.
According to the content of (1), confirm and draw the program and construction method of rotary kiln installation.
Draw up the form with required tools, machines, testing instrument, fuel and material consumption.
Draw up construction schedule according to general plan of the plant.
Draw up construction organization and dynamic labor form according to the erection program, construction method and construction schedule.
According to the construction characters and construction method of rotary kiln, confirm safety measures.
According to relative acceptance rules, technical requirements of drawing and special requirement of specific section draw up quality guarantee measures of rotary kiln erection.
New type dry process cement technology of our country has passed over 20 years since importing to self-developing, we gradually summarize and innovate, and have gone out of our country. Whatever process design, assembly capability or erection capability has reached international advanced level. However concerning the management of new type dry process cement production, as the development of new type dry process cement process is too fast in domestic market, the enterprise is comparatively slow, so human resources is comparatively lack, meanwhile many enterprises don’t have enough understand of new type dry process cement production, so the manufacturing management, equipment management, quality control is not very scientific and reasonable, especially for the rotary kiln operation in central control room, there are a lot of mistaken ideas, so sometimes they can’t solve the process barrier.
Writer has been in new type dry process cement production industry for over 20 years, during the process of supplying technical services, I felt that the control and operation of new type dry process cement kiln should be researched and developed. Now this article mainly discussed the mistaken ideas of new type dry process cement kiln operation.
