: >Anti-shock wave doors< <>The road to research and development of anti-shock wave doors is full of thorns, growing little by little and perfecting little by little. Now the anti-shock wave doors independently developed and produced by Shengmei Mining Machinery fully comply with national standards. The inspection reports, qualification certificates and certificates are all complete, making it convenient for you to deliver to the mine.

When used, the number of ventilation valve groups can be determined according to the air volume required by the underground blasting material library and the total return air duct negative pressure value, and each group can be adjusted. The opening angle of the group valve hanging plate is fine-tuned to meet the optimal ventilation volume. Once an explosion
