Working principle of vertical shaft impactor VSI sand maker
VSI sand making machine is mainly used for sand making in construction, it is the advanced equipment for producing artificial sand, which is specially designed to provide high quality sand and aggregate for the construction of highway, high-speed railroad, high-rise building, municipal, hydropower dam and concrete mixing plant, and it is also the shaping equipment in the field of artificial sand making and aggregate plant.
Usually it is worked with vibrating feeder, stone crusher, vibrating screen, sand washer, crusher, etc. to form a more economically and efficiently sand making line.
VSI sand making machine investment is 35% to 50% lower than the same scale of traditional process equipment, but output efficiency is 35% to 50% higher than the same scale of traditional process equipment.
For example, limestone with a finished product size ≤ 5mm accounted for more than 90%, river pebbles a finished product size ≤5mm accounted for more than 80%.
Long-term operation and maintenance cost is 35% to 50% lower than the same scale of traditional process equipment, it is widely used in the mechanism of sand and stone materials, cement, resistant materials, metallurgy and other industries.
