Rotary kiln in the heating and cooling process, because the brick kiln and the resulting amount of expansion and contraction is not the same, when the deviation reaches a certain level, the bricks will be damaged due to the force. Overhaul overhaul into the kiln which can sometimes find some broken tiles, you can lift your hand, this is caused by heating and cooling too quickly. Therefore, heating and cooling rate must not be too fast. Each heating temperature curve must be developed, the operator must strictly follow the temperature curve warming. Every half hour to scan the next point of the actual temperature, and with the requirements of the heatingJaw Crusher curve to compare the length of heating time according to how much the decision to change the brick. In addition, a good time to stop the kiln but also control the cooling rate after high temperature fan speed and throttle opening to small to large, slowly increase. Generally can be hired from the kiln to stop the kiln to take at least 16 hours of cooling time.
