Point inspection is one of the patrol supplementary means, is a necessary meansto consist rotary kiln running state facts detection system. The point inspection is aimed at detect and troubleshooting for the rotary kiln's key parts, node caused failure under the rotary kiln normal state or down state, to improve the reliability of the rotary kiln.
Unloading the clinker in the cement rotary kiln contains a certain amount FaCaO, during storage, can absorb moisture from the air, part dispel as calcium hydroxide, generated expansion stress in the clinker internal, thereby enhancing the grindability of the clinker, improved water stability. So improve cement quality, improve grindability.Ensure the production of rotary kiln and mill production balancing, help to control the quality of the cement. Unloaded rotary kiln clinker according to the good or bad quality, sub-heap storage for use, and maintain the stability of the cement quality. Clinker storage period require 5 to 7 days.
Large gradient indicates that the material in the movement of the rotary cylinder faster, less drying time, inclination small, the material in the cylinder body still longer, the rotary kiln inclination for the different nature of the materials is different. Then how much gradient to select is the most appropriate size of the rotary kiln slope, From the point of view of experience, the current rotary kiln the optimum range of the inclination angle of the cylinder is between 3% -4%.
In order to implement better maintenance, repair and maintenance of rotary kiln equipment, must implement effective and reliable operation inspection system. The preparation equipment inspection, point inspection program, its purpose is aimed at getting better and better maintenance, thus reducing the failure rate of the device, and to extend the life of the equipment. For this type of large-scale mechanical equipment,like rotary kiln, their patrol, point inspection and maintenance should be continuous, uninterrupted, comprehensive, Inspection and point inspection should be applied to the rotary kiln various aspects in running state and downtime state.
