乡镇瓦厂粉尘危害严重 ,而大多缺乏必要的通风防尘措施 ,或因设计不合理而起不到应有的作用。通过测定 ,原料粉碎、筛分工序粉尘浓度高达 16 76 5ｍｇ/ｍ3。我们选择生产工艺在国内普遍性的某乡镇瓦厂 ,优化设计通风防尘措施 ,实施后效果非常明显 ,工人作业现场的粉尘浓度降到 Township tile factory dust damage, and most of the lack of necessary ventilation and dust control measures, or due to unreasonable design and can not play its due role. Through the determination of raw materials, crushing, screening process dust concentration up to 16 76 5mg / m3. We choose the production process in the country’s general one of the township tile factory, optimize the design of ventilation and dust control measures, the effect is very obvious after the implementation of the worker’s job site dust concentration dropped to
