As the insulating layer is laid between the cement grinding lining plate and the inner surface of the tube according to the design requirements, if there is no requirement, the cement mortar with the compressive strength grade of 42.5MPa can be filled as much as possible. The excess part is extruded by the bolt of the solid liner plate. After the cement mortar solidifies, the lining bolts can be tightened again.
The cement grinding lining board needs to carefully check the geometric shape of its lining board bolt hole and lining board bolt, and carefully clean the flying edge, burr and protuberance on the lining board bolt hole and lining board bolt, so that the bolt can freely enter the required position.The complete set of lining bolts shall be composed of blinding bolts, dustproof washers, flat washers, spring washers and nuts to prevent leakage of dust. The dustproof MATS shall not be forgotten during use.
The cementitious lining bolts need torque wrench to be used in the process of fastening. The lining bolts of different specifications should be tightened according to corresponding tightening torque requirements.After the advanced two-medium quenching process, it has the characteristics of high quenching hardness and high toughness value, which makes the lining plate have good wear resistance performance. Compared with the high-manganese steel lining plate, the alloy steel ball mill lining plate in the medium alloy two-medium quenching shows excellent cost performance.
