Fly ash by grinding mill grinding to achieve the required fineness of concrete, and then pulverized fly ash with gypsum (or use crushed and grinded limestone powder) and added directly by a certain ratio sent into pulper stirring. In the pulp, the timing of water is conducive to appropriate concentration initially prepare a slurry.

 

Finally, fly ash, cement, gypsum powder fed by the feeder within electronic powder measure scale, the cumulative metered by the metering scale tripper unloaded into pouring mixer. Materials and waste slurry ash slurry storage tank by the respective valve opens under the floor directly into the slurry ingredients within electronic measurement scale accumulation, when the weight of the slurry reaches the ingredients required, by the automation system tank discharge valve closed to stop the discharge. Good measure slurry poured into the mixer according to instructions.
