Indirect heat transfer dryer common faults and repairs

Possible failure of indirect dryer

Approach

Exhausted material contains too much water

At this point, you should increase the amount of fuel used or reduce the amount of feed. This operation should be gradually adjusted to the appropriate state. A large adjustment will cause the water content of the discharge to be high or low, failing to meet the product quality requirements.

The two retaining wheels are repeatedly subjected to repeated forces

This phenomenon should check the contact between the roller and the support wheel. If the same set of supporting rollers are not parallel or the connecting lines of the two supporting rollers are not perpendicular to the axis of the cylinder, the force of the retaining wheel will be too large, and the supporting wheel will also be abnormally worn. This phenomenon is often caused by low installation accuracy or loose bolts, which are caused by the deviation of the roller from the correct position during operation. This phenomenon disappears as soon as the tray is restored to the correct position.

The large and small gears in the operation are not sounding normally.

In this case, check the meshing clearance of the large and small gears. The adjustment will return to normal. If the pinion is worn out seriously, it should be replaced in time. The gear cover is well sealed to prevent dust from entering. The sufficient lubrication and reliable lubrication are the key to improving the service life of the gear. Thick gear oil or black oil should be added to the large gear cover
