我公司 １００ ｋｔ／ａ过磷酸钙生产系统粉磨工段采用干法风扫磨工艺，选用Ｍ７－２９－Ｉ型１２Ｄ煤粉风机配套完成风扫风选。风扫磨的风扫能力取决于与之配套的高压鼓风机。 煤粉风机提供充足的风量，抽取热风炉内的炉气，保证磨机的风扫与烘干，经过风扫磨加工合格的磷矿粉
Our company 100 kt / a SSP production system grinding section using dry air sweeping process, the selection of M7-29-I-12D pulverized coal fan supporting the completion of the wind swept the wind election. Wind sweeping air sweeping ability depends on the accompanying high-pressure blower. Pulverized coal fan to provide adequate air volume, hot air furnace extraction furnace gas to ensure that the mill wind sweep and drying, after wind swept grinding qualified phosphate rock
