1Limestone breaking, conveying and storage. A MB56/75 model crusher (fix up in open) is used to break limestone. While the maximum incoming size of material ≤1500mm, and discharge size of granularity ≤75mm, the capacity of this crusher is 500600t/h, discharging limestone is conveyed by belt conveyor into Φ80m round limestone pre-homogenization piles(storage 34100t) to be pre-homogenized and stored. The stocker (with piling capacity of 800t/h), cantilever, schort continuous cloth, bridge type reclaimer (capacity: 500t/h), head face taking material, center discharging. After being pre-homogenized, limestone is conveyed by belt conveyor to raw material batching station.

 2Assist to raw material storage, breaking and conveying. Assistant raw material sandstone and iron ore are conveyed to plant by carrier, discharged to open stock dump and stored. Specifications of open sandstone stock dump and open iron ore stock dump are 60 m×20m with storage of 5100 t and 32 m×20m with storage of 2730 t. Model PC1609 hammer breaker is used to break sandstone and iron ore. While the maximum incoming size of material ≤600mm, and discharge size of granularity ≤25mm, the capacity of this crusher is 5070t/h. After being broken, the sandstone and iron ore are conveyed by belt conveyor to respectively batching stations of raw material batching station. Assistant raw material powder coal ash are conveyed to plant by bulk carrier, discharged by self-discharging system to coal ash batching stations of raw material batching station.

3Raw material batching station. Raw material batching station includes four batching stations for limestone, sandstone, iron ore, coal ash (specifications are all φ12 m×25m, respectively storages are 2200,1600,2200,770t). Weighing feeders are settled at the bottom of batching station, giving out states mixture ratio material. Mixed raw materials are conveyed by belt conveyor into vertical grinding system to be grand.

4Treatment of raw material grinding mill and waste gas. Model MLS3626 vertical mill (fix up open) is used as raw material grinding mill, its drying hot source comes from pre-heaters waste gas. When the size of incoming raw material 90%≤75mm, fineness of production is 80μm, square hole sieve sifts it <12%, internal raw meal contains moisture <8% and out coming raw meal moisture is <1%, the system capacity is 185t/h (after abrasion). After being separated by pulverized-powder collector, out coming raw mill is mixed with fine powder collected by humidifier and electric dust collector. Then through the chute and bucket elevator, the mixture is conveyed to raw material homogenization warehouse to be homogenized and stored. The waster gas from mill is discharged into air after being treated by electric dust collector.
