The preparation method of the polishing grinding block is introduced, the performance experiment is represented and the factors to influence the polishing effect are analyzed.

In grinding blocks library, batch grinding block of ball mill was developed, on the base of which, batch grinding block of rod mill and autogenous mill can be set up continuously.

Block, backplane: high-quality oak molding by the mold pressing, grinding process by profiling, do the multi-layer paint finishes.
