How to Solve the Blocking Problem of Rotary Kilns

As the blocking problem is the most common trouble in the working process of the rotary kiln, users probably want to learn more about the useful measures to prevent the rotary kiln from blocking during the operation.

According to our technicians, there are about three main steps for us to take when using the rotary kiln:

First, we need complete inspection before starting up the rotary kiln:

1. We should check the pre-heating system to guarantee its normal performance. It’s necessary for users to do complete inspection of the whole system and to clean the pipelines.

2. Before opening the rotary kiln, we should also check the ash valves to make sure they can work flexibly without blocking and breakdown.

3. If the adjustment is needed, we can rearrange the machine to avoid the overweight and underweight problems which will cause the equipment to run abnormally.

Then, before we open the rotary kiln, we should make sure that all doors, flanges, sampling ports and ash valves are sealed tightly without air leaking. When we are handling the blocking problem, we must not forget to check on the door security. Usually we will use the fire proofing bricks to close off the doors set on the rotary kiln.

Finally, when the temperature of the rotary kiln rises, we should arrange the ash valves frequently during the process of adding materials into the equipment. In the actual operation, every customer should follow the description and rule made by the machine manufacturers to keep proper temperature within the kiln. To operate slowly and correctly will play a key role in the real production line.
