The granite crusher is a crushing device that uses impact energy to break up materials. When the material enters the action area of the hammer, the high-speed impact of the hammer causes the pulverized material to be continuously thrown onto the counter-attack device installed above the rotor, and then the counter-attack lining rebounds back to the action area of the hammer and is counter-attacked. Repeat the crushing into the small disaster chamber. Until the material is broken to the desired particle size, it is discharged from the lower part of the machine. It is characterized by uniform fracture of multiple cavities and is suitable for breaking hard rock. Low feed opening for easy line layout and increased feed size. Fully hydraulic opening for easy maintenance and replacement of consumables. The new wear-resistant material gives the hammer, counter-liner and liner a longer life.
