are used in a very broad range of wear resisting surfaces and for the repair of wear resisting surfaces of coal mills. Indeed, these alumina liners do provide the best solution for giving the desired performance.
A study was conducted for erosion pattern of coal mill internals due to coal flow in vertical spindle pulverizers in PC Boilers. The coal and air mixture makes a number of turns before it reaches the Multiple Port Outlet. The changes in direction of flow cause the majority of coal particles to accumulate in the "Red marked" portion of the pulverizer.
