During our use, we found that the continuous use of the shot blasting machine for a long time and non-intermittent use caused the steel plate to heat up. During the heating process, the steel shot was still constantly hitting the surface of the wear-resistant part, causing the surface to form a concave Point, using this way for a long time will cause the wear-resistant components of the surface of the wear-resistant parts to drop sharply, which will greatly reduce the service life of the wear-resistant parts. Therefore, during the use of the equipment, we must appropriately leave the shot blasting machine with a temperature drop. Time, so as to maintain the long-term good operation of the equipment.
