The so-called safe operation of the cycle is the rotary kiln in operation does not occur in the following circumstances as safe operation, the number of days of its

operation is the safe operation of the kiln cycle, otherwise the safe operation period shall be interrupted. 1, due to red kiln stop check; 2, due to the kiln for brick and

stop the kiln; 3, due to major equipment accidents kiln system, stop the kiln over 4h. After each interrupt, calculate the safe operation cycle begins again. The

following occurs stop the kiln, safe operation cycle is not interrupted: 1, as planned repair or defect is discovered prior plan to stop the kiln process; 2, due to power

outages, broken material, broken coal caused to stop the kiln. In calculating the safe operation of the cycle, you must temporarily stop the kiln deducting all the time.

Wet process kilns operating cycle safety than required to achieve 100d, 70d dry kiln reaches over and semi-dry kiln with preheater reach more than 50d. The so-

called life cycle refers to the lining: rotary kiln with firebricks use of time, non-lining causes time to stop the kiln linings shall not affect the continuity of the life cycle.

Generally longer than the life cycle of the kiln lining safe operation cycle. Lining life cycle calculation method is: open the kiln firing to stop the kiln linings overhaul

when lining minus the number of days in operation of parking time, is lining life cycle. Please indicate Henan YuFeng Heavy Machinery
