The process explanation of Raymond mill processing fly ash.

Raymond mill processing fly ash process, fly ash should be superfine Raymond mill, Raymond mill for fine grinding, to improve its reaction speed. It is difficult to guarantee the strength of the cement content with less fly ash in this process. Otherwise, only 2% ~ 3% of cement is added. The grinding ratio is about 20% of the total amount of fly ash. Fly ash should use first grade or second grade ash, tertiary ash can not be used without treatment. In addition, the best use of dry ash, do not use wet ash.

Ordinary Portland cement should be used for cement, and low alkaline sulphoaluminate cement, fly ash cement and composite cement should not be used to guarantee its excitation effect. If the density of ceramsite is reduced, a certain amount of lightweight materials can be added such as perlite, waste polyphenyl powder or granules, wood powder, sepiolite, pumice and expanded vermiculite. When the core is not covered, the lightweight materials should be ground into powder, with a fineness of 100 ~ 150 eyes. When the core is packed, these lightweight materials can be used as core materials with a grain size of 3 ~ 5mm. It is better to use magnetized water for granulation water. Using magnetized water can increase the strength by about 10% ~ 15%. When the temperature is low, for the sake of coagulant, can use 50 ~ 60 ℃ hot water. When natural curing, there should be insulation and moisturizing measures. Heat preservation can cover grass cover, acrylic cotton, mineral quilt, etc., wet can cover plastic cloth. When the steam curing is adopted, when the tunnel kiln or the energy saving maintenance kiln is not enough, the ordinary house can be converted into a curing kiln.
