原料车间新工艺介绍

A Pyrlte Crushing Process

介绍了180kt/a硫铁矿制酸厂原料车间的新工艺。矿石通过电振给料机均匀地送入自磨机,粉碎至≤3.5mm。粉碎后的矿石以热风为载体抽出,经沉降箱、旋风分离器和静电除尘器收集,供焙烧使用。该工艺改善了原料车间的操作环境,总收尘率达99.92％,岗位环境粉尘含量<2mg/m^3。

A new pyrite crushing process for a 180 kt/a HzSC4 plant is described. Pyrite was fed smoothly into a self-mill by a electric vibrating feeder and reduced to ≤ 3. 5mm. The kibbled pyrite was transferred with hot air as carrier and collected by passing through a settler, cyclone and electrostatic precipitators for roasting. The process improved operation environment with a total dust collection of 99. 92% and a dust content in air of <2mg/m3.
