granite impact crusher / used mobile impact  
  Impact Crusher Introduction: 

Regarding the working principles of the various crushers, according to the user specific service condition information feedback, and combining its features, Shanghais Minggong designed this new generation of the high-efficient fine crusher. It is specially used in the area of artificial sand making, and it is the substitutes of the rod mill, and the vertical shaft impact crusher. It is widely used in the areas of chemical ,building material, metallurgy, mining, coal, sand crushing and refractory material, especially for high-efficiently crushing the materials of the moderately hardness, such as limestone, cement clinker, iron ore, shale, dolomite, granite, gypsum, mix material 
 

During operation, fine impact crusher is driven by the motor which makes the rotor revolving in high speed. When the materials are sent into the first cavity, it will be impacted by the hammer; and then be smashed into the second fine cavity for crushing, finally it is discharged out.

1. Hammer is made of high chrome; liner board is made of wearable materials;
2. More suitable for crushing hard rock, high efficiency, low consumption;
3. Final products is cubic, discharge opening is adjustable;
4. Make the crushing flow chart simple.
