MIV800 Vertical Shaft Impactor


With high speed rotating impellers, the MIV-800 Vertical Shaft Impactor throws material out from center to circumference,by using the material’s own centrifugal force to cause impact with the impeller shoes or the anvil faces,resulting in rock-on-rock or rock-on-iron crushing。Due to precise manufacturing and complete tests,the MIV-800 can guarantee smooth operation at high speed,long service life and superior crushing results。
With its wide operation range and first class performance,it is the most effective and reliable crusher,especially suitable for fine crushing and medium fine crushing of grinding material,fire-resistant material,cement,quartz sand,steel grit,furnace cinder,copper ore,iron ore,gold ore,river gravel,concrete aggregate,asphalt aggregate,and brittle material。This highly effective and energy saving crusher is also a superior and first rate sand production equipment and can save up to 50% of energy,compared with traditional sand making machines。
According to customer’s requirements, MIV-800 can be equipped with closed rotors or open rotors。

Features  :
- New,special and simple structure,smooth operation,low operating cost。
- Quick exchange between “rock-on-rock” and “rock-on-iron” applications,only one machine for crushing and sand production。“Rock-on-rock” technology reduces parts wear and production cost。

- Low energy consumption,high production ,high crushing ratio,energy saving。- Re-shaping function,product shows cubical form,high bulk density。
- During production,stone material forms a protective layer,which protects the machine from wear and enhances durability。
- Few abrasive parts are made of specially hard wearing resistant material,for small volume,low weight,and convenience during exchange。
- The automatic air circulation system reduces dust and powder。
- Little influence of material’s moisture content,which can reach up to 8%。
- A lubrication oil station with an oil pump for circulatory lubrication of the main shaft bearing ensures constant oil supply to the main machine,as well as automatic control and accident alert。
- The upper lid can be lifted via a hydraulic system,easy operation。
