600t/d rotary kiln clinker cement production line By limestone mining, the limestone is conveyed by the car into the 18 × 20m stack shelf for driedcrushed and then conveyed by belt conveyerS-type unloading car into 20×25×15m pre-homogenization reactor shelf.And limestone is set as a "T" on both sides of the corridor fabrics, forms a "people" shaped reactor materials. Simple pre-homogenization operation used by loaders head face taking material ,the homogenization coefficient could reach 3-6.Loader takes materials and sends them to the belt conveyer, these are conveyed by hoist into φ6×14m round limestone to be stored. Raw materials are made of four parts :limestonesandstoneclay and iron dust.And they are sent to the Φ2.6 m × 10m ring-grinding mill system to be ground after proportioning at the bottom of batching station.To achieve the purpose that controlling the raw rate , we use computer batching system to regulate the proportion of raw material.After chosing by the powder concentrator,the eligible raw materials are conveyed into the 4-φ8×18m batch raw meal homogenizing silo to be d and stored, by chain conveyor and hoist. And the coarse powders are returned to the wheelhead to be ground again by the chian conveyor. The waste gas of cement grinding system goes into cyclone separator and electric dust collector to be treated then discharged into air.The collecting fine powders go into the fine chain conveyor, and then conveyed into the raw meal homogenizing silo.
