The coal cakes loaded by the side-loading coal car are always tilted back and forth

:Q: In the new plant, the heavy equipment used is quite adequate for controlling the moisture content of coal (although it’s not very stable). Whenever coal cakes are prepared, one or two of them tend to tip over. There is no shaking when the coal carts transport these cakes; however, the speed is reduced when shaking occurs, but the cakes still tip over. What could be the reason for this?
Either it falls over completely or one of its corners is damaged; it always falls over by about 1 meter forward or backward
It depends on the time taken for the manipulation, the up and down movement of the hammer, whether the rear panel moves unevenly, as well as the technique used. To solve the problem, it’s necessary to identify the issues on-site, pay close attention, record the time taken and the techniques used, and look for patterns. Identify what patterns exist when the structure doesn’t collapse, and if it does collapse, analyze the reasons behind it.
The main reason lies in the operational aspects, forcing the rammer workers to gain experience through trial and error
Check the distance between the rammer and the front and rear baffles, and adjust it as necessary. Also, control the feeding amount of the feeders at the front and rear, and increase the ramming time at those positions during ramming.
If there are no major issues with ramming, I think we should consider the moisture content of the coal fed into the furnace; this problem occurs quite frequently when the moisture level is not appropriate.
Try using rubber for soft contact at the rear limit of the rear panel
