1, High efficiency and lower consumption. In the condition of the same material, power and the fineness, its capacity is increased by 40% compared to the jet mill and mixing grinder. 2, Longevity. In the condition of the same power and the fineness, the spare parts have a longer lifetime, usually more than one year, to the shaft impactor crusher and the turbine crusher. 3, Non-bearings and non-bolt in the grinding chamber. Because of this, these questions destroying the machines can never exist for bearing, sealing element or the bolts loose. 4, The fineness of final products can add up 5μm, and screening rate is 97%.
