Precautions in use of rotary dryer

Rotary Dryer As a drying equipment, it is widely used in mining equipment. Direct and indirect rotary dryer heat transfer.

 Rotary Dryer

1. The installed dryer should be run in for no less than 4 hours, and any abnormal situation during the commissioning should be handled in time.

2. After the test run, tighten all the connecting bolts again and make up the lubricating oil. After the test run is normal, the load test run can be carried out.

3. Before the load test run, all auxiliary equipment shall be put into trial operation without load. After successful single unit test run, it will be transferred to joint test run.

4. Ignite the hot blast stove dryer to preheat, and turn on the dryer at the same time. Do not heat the cylinder without rotating to prevent the cylinder from bending.

5. According to the preheating condition, wet materials are gradually added into the drying cylinder, and the feeding amount is gradually increased according to the moisture content of the discharged materials. There should be a preheating process for the dryer and a preheating process for the hot blast stove to prevent sudden fire. Prevent local overheating, uneven thermal expansion and damage.

6. The fuel burning value, the heat preservation of each part, the moisture content of wet materials, and the uniformity of feed rate affect the drying products and fuel consumption. Therefore, it is an effective way to improve economic benefits to make all parts reach the state as much as possible.

7. In the working state, the supporting roller frame shall be filled with cooling water. All lubricating parts should be lubricated in time.

8. When the furnace is close to the outside temperature, it is necessary to turn the hot air cylinder to turn off when it is close to the outside temperature. It is forbidden to stop at high temperature to prevent the cylinder from bending and deformation.

9. In case of sudden power failure, the hot blast stove shall be shut down immediately, feeding shall be stopped, and the cylinder shall be rotated for half a circle every 15 times until the cylinder is cooled. Special personnel shall be responsible for this operation procedure, and violation of this procedure will cause cylinder bending. Serious bending of the cylinder will make the dryer unable to work normally.
