The liners are installed then the bolts are tightened to the required load using the correct techniques, the mill is then put back in operation. A first re-tightening (re-torque) of the liner bolts is usually done within 24 hours of production at full load.Hexagonal boron nitride (h-BN) was ball-milled at various rotation speeds (150–600 rpm) using a planetary ball-mill. Ball-milling disrupted the layered structure of the h-BN, resulting in significant increases of surface area. Ball-milling at 400 rpm gave the .
