VSI Series Vertical Shaft Impact Crusher

Operation principle :

Generally speaking, the operation principle of vertical shaft impact crusher is "stone strikes stone", that is, materials enter the impeller cavity, which is turning at high speed, at the top. With centrifugal force, the materials will impact other materials that fall around the impeller. Then, after interact striking, materials will impact on material layer between the impeller and scale board for many times and will be rubbed and crushed. Then they will be discharged at the bottom.

Features:

1.Low wearing parts consumption—Perfect impact angle design of the crushing cavity, less friction against the wearing parts. The operation cost reduces 40%.
2.Perfect product shape — Cubic products, suitable proportion and adjustable fineness modulus. It fits especially man-made sand and stone reshaping. The effect of making and reshaping sand has been increased 30% compared with the traditional equipment.
3.Hydraulic devices are maintained easily—Hydraulic door-opened device make the repair in the crushing cavity easily .Shorten downtime and save effort.
4.Automatic test, safe and reliable—Vibration display and warning device are set. The machine will be warned to stop working when abnormal phenomenon appears.
5.Thinning oil lubricant and automatic maintenance—The original German thinning oil lubricant station, double-pump injection system guarantees the oil supply. The machine will stop automatically when there is no oil and pressure. Water cools the oil and electric motor is heated in winter.
