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 500∼600t/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 50∼70t/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.
