The JKR two-stage vacuum brick making machine is suitable for producing various material brick such as gangue, shale, pulverized coal ash as well as clay. This machine twists the dragon to use the wear-resisting metal powder froth spray coating technology; The higher authority stirs the axis, to twist on the dragon macro-axis as well as the fuselage the lower part of the body and so on, passes through the effectiveness, the quenching and tempering, quenching processing; The speed reducer gear is the hard tooth face; The coupling uses the spiral to press the type patented technology and so on, enhanced the useful life of equipment large scale. At the same time, this machine rational design, the structure are compact, cannot install the foot bolt then smooth operation, can reduce the equipment generating process large scale because of the vibration consumption power.
