Cement Rotary Kiln

    • Cement Rotary Kiln Laser Measuring Is More Accurate Than Latitude

      The cement rotary kiln is adapted to the need of the industry developed a new type of cement rotary kiln calcining equipment, the measurement principle of cement rotary kiln kiln method: laser measurement, laser is a good monochromaticity, concentrated energy, small beam divergence angle of light. cement rotary kiln laser technology, has been applied in the industrial sector. Use of cement rotary kiln the laser beam can be easily carried out a variety of work. Laser measurement of cement rotary kiln and the theodolite method compared with cement rotary kiln, clear and intuitive method is simple, accurate, reliable, due to the reduction of a series of measurements and conversion process, laser measurement with high accuracy and more convenient for cement rotary kiln.

      Determination method for cement rotary kiln, installation of a new cement rotary kiln and the transformation of the old cement rotary kiln cement rotary kiln, when no heat exchange device, using a cement rotary kiln inner fixing method is more convenient. Specific steps: Determination of cement rotary kiln sites located in a frame; the determination of position of the center of cement rotary kiln cement rotary kiln method; determine the baseline; find is comparing laser beam into a turning plate coordinate paper facula center circle and the origin of the relative position is known, the size of the deviation. Then by adjusting the bolt, nail wire link or adjusting the supporting wheel, when the spot with the cement rotary kiln cylinder center coincide. cement rotary kiln tracking method can ensure the straightness of cement rotary kiln, cement rotary kiln determination outside except for aligning the axes of the cement rotary kiln cylinder, also can understand idler wheel axis. Also need to measure each roller, roller diameter and the profile of roller and pad clearance, and after accounting.

       

    • Cement Rotary Kiln Temperature Control Strategy

      The current cement rotary kiln calcining is pellets sintering process is the most important stage, so the cement rotary kiln temperature control becomes the key factor. The cement rotary kiln attentive in large time delay, nonlinear, time-varying and other technological features, using the cement rotary kiln temperature adaptive fuzzy PID-Smith compound control strategy, and according to the cement rotary kiln heat balance analysis results and Smith predictor features for relay identification method, identification of different cement rotary kiln temperature temperature control model, in order to discrete way of approximating actual system model of continuous change, eventually reducing cement rotary kiln model mismatch caused by the prediction compensation error.

    • Barrel Structure of Cement Rotary Kiln

      cement rotary kiln barrel from the connection to all welding. cement rotary kiln barrel has a series of shortcomings of articulation. Title nail loose, causing the cement rotary kiln cylinder body of serious deformation, local firebrick falling accident, causing red kiln. Rolling ring of cement rotary kiln under the cylinder is made of a steel plate combination, each layer can not be very good. The cement rotary kiln cylinder body surface is not smooth, bricklaying is not convenient, cohesion structure aspect to meet with a foot plate, and with nails, will make the cement rotary kiln cylinder body weight increase of 20-25%, and the manufacturing workload. Therefore there is no longer the design and manufacture of articulation cement rotary kiln barrel.

       

    • The Cement Rotary Kiln Cylinder Body Main Calculation Purpose

      To determine the selected cement rotary kiln shell thickness is appropriate; according to the calculation results of the cement rotary kiln adjustment of span, so as to meet the reverse force principle, even if the cement rotary kiln the bearing reaction force to close, so that the cement rotary kiln supporting device design are unified; second is to satisfy the cement rotary kiln moment principle, make the cement rotary kiln each support section bending moment to close, avoid to meet individual requirements and the thickened section of cement rotary kiln barrel. When the cement rotary kiln supporting files less number of cement rotary kiln, due to structural cause, the principle is not easy to be fully realized, not importune; for cement rotary kiln supporting components and basic design load, two cement rotary kiln support cooling machine, dryer and the cement rotary kiln cylinder to cylinder support beam, internal force calculation is relatively simple. Block three above belongs to statically indeterminate beam.
