Description

[0003] The raw materials of energy-saving insulation bricks are various, but the common insulation bricks usually use gravel as aggregate. The mined stone is crushed by a stone crusher to produce gravel with a particle size meeting the requirements, which is transported to the insulation brick production line.

[0004] The impact crusher is the most commonly used stone crusher. When working, the rotor rotates at high speed under the drive of the motor. The stone material enters the hammer action area and is broken by the plate hammer on the rotor.
