Anchor bolts prevent excessive movement and wear on moving parts such as the bearings, rotors, mechanical seals, couplings and crankshafts. We design replacement bolts that allow for stretch within the bolt's elastic limit, that are suitably resilient to dynamic loads and that accommodate the appropriate creep of the foundations with respect to bolt stretch.

PARAMETER OPTIMIZATION OF LARGE SAG MILL LINER BASED …

Due to its strong lifting capacity and excellent grinding performance, the trapezoidal liner is widely used in the SAG mill.
