specific Embodiment 1
[0029] Specific embodiment 1, the weight percent of each component in the vibrating material is: 94% magnesia, 5% composite binder, 0.5% coagulant, and 0.5% polycarboxylate superplasticizer.
specific Embodiment 2
[0030] Specific embodiment 2, the weight percent of each component in the vibrating material is: magnesia 96%, composite binder 3%, coagulant 0.8%, polycarboxylate superplasticizer 0.2%.
specific Embodiment 3
[0031] Specific embodiment 3, the weight percentage of each component in the vibrating material is: magnesia 95%, composite binder 4%, coagulant 0.6%, polycarboxylate superplasticizer 0.4%.
[0032] The method for preparing the above-mentioned no-bake magnesia vibrating material includes the following steps in sequence:
[0033] a) the massive magnesia is broken into large particles with a jaw crusher;
[0034] b) Use a roller crusher to crush the large particles into small particles with a particle size of 0-2mm;
[0035] c) Sieve the small particles according to different particle sizes, and the small particles with a particle size of 0-2mm are qualified raw materials;
[0036] d) Take small particles with particle diameters other than 0-2 mm to return to the cage, and use a roller crusher to crush unqualified raw materials;
[0037] e) Sieve the small particles according to different particle sizes, and the small particles with a particle size of 0-2mm are qualified raw m...
