Hengxing explosion-proof ball mill is essential equipment flammable and explosive materials. It has a strong adaptability and productivity, a good seal to prevent dust leakage in a row work and easy to adjust the fineness , Its working principle is that the high-pressure air bring the raw material into low-speed rotating cylinder mill from the air shaft. the material can not be fineness will get back to hollow shaft for grinding again. Apply to aluminum, magnesium, sulfur, and other easy-grinding of explosive materials. To the use of sealing material, air transport and the protection of nitrogen to make it easy to effectively prevent the rare boring mills in operation in an accident.
