1. Coal ore fan buffer is usually installed under a buffer or a fan -shaped steel bracket. The impact absorption board is a prefabricated enhancement plate, which can balance multiple buffer materials under the board. The number of shock absorber is determined by the air flow of the fan, but reached more than four. The type selection of the impact absorber is determined by dynamic calculation.

2. The types, specifications, and quantities of buffer materials should not be changed during construction. The ore fan buffer is configured with a shock absorber under the buffer board. The center force of the preparation hole is not offset. The surface of the buffer should be smooth, or the surface of the buffer should be flat based on this, so the power of the buffer must be uniform. The spring buffer has a low frequency of a larger reservoir. It has a good impact on eliminating external strikes and vibrations.
