A mill load is defined as the instantaneous total charge of a ball mill and is composed of a new feed ore, slurry, water, and steel balls inside the mill (Tang et al., 2015a). Overloading causes "mill spitting ore," coarsening on the particle size of mill outlet, "mill blockage," "belly be filled full," and production process break ...

Chipload is simply defined as the thickness of a chip which is formed during the machining of a material. Chipload is critical because if the chip is the proper size, the chip will carry away the heat promoting long tool life. If the chip is too small, the heat is transferred to the cutting tool causing prematurely dulling.
