coal slime dryer pallet is installed at the lower end of the drum and is mainly used to bear the weight of the cylinder. However, after the coal slime dryer is used for a long time, the front and rear pallets of the coal slime dryer will have different degrees of wear. The front pallet wheel is lighter and less obvious, and the latter pallet wheel is more severely worn and often becomes saddle-shaped or step-shaped. In response to this situation, we must find out the reasons for the severe wear of the rear pallet wheel in time and take the correct method to solve it.
First, defects in the structural design of the coal slime dryer will cause severe wear of the rear bracket, because the cylinder of the coal slime dryer is placed on the bracket wheel at a certain angle. The structure and size of the front and rear large wheel belts of the cylinder are different. The width of the front and rear wheel belts is 120MM, and the width of the rear wheel belt is 105MM. The width of the front and rear wheels of the coal slime dryer is the same, both 160MM. According to the figures above, the area where the rear bracket wheel contacts the wheel belt is narrower, and the cylinder is inclined at a certain angle, which has a greater pressure on the rear bracket wheel. After working for a long time, the rear bracket wheel is easily deformed.
Second, improper operation of the staff will also cause serious wear of the rear bracket. For example, when some mining processing plants are drying materials, they do not pay attention to the up and down movement of the cylinder, or the adjustment method of the front and rear brackets, which causes huge changes in the force of the rear brackets to be affected during the entire work process, causing serious wear of the rear brackets.
3. The maintenance method of the coal slime dryer is incorrect. When the coal slime dryer is used for a long time, due to the long-term effect of high-temperature airflow, the wheel belt and pad on the cylinder will be seriously worn and deformed, and the wheel belt may become oval, so the pressure on the bracket will change, which will eventually cause the bracket to wear seriously.
Severe wear of the rear bracket of the coal slime dryer will affect the smooth progress of the drying process and greatly shorten the service cycle of the parts. Therefore, users should pay attention to the daily maintenance and maintenance of each component of the coal slime dryer to extend the service life of the equipment.
