The front weld of a liner, which runs transverse to the flow of abrasive material, is susceptible to wear, increasing the risk of the entire plate breaking off quickly. When a weld becomes cracked or worn, small particles and dirt begin to accumulate between the liner plate and the floor structure. These particles act as a strong wedge, exerting pressure that gradually separates the liner plate from the floor, causing further cracking of the weld until the plate eventually falls off. To prevent this, it is crucial to regularly inspect and maintain the welds.
