本文内容根据石英制粉厂生产环境,劳动情兄,厂房中粉尘颗粒数,工人体格检查及102例矽肺照片的分类等进行初步的分析。生产过程及一般情况大块石英,用铁锤人工砸碎然后过筛。铁筛用绳子悬挂梁上,筛之一端有木把,用手摇动,第一遍是粗筛,较大的颗粒搬回重新砸碎,筛下的计重论资。第二遍是细筛,将粉及颗粒分开,颗粒大小,根据生产的需要。另外还有一部小机器磨,常不开,作用不大,机器磨设在另窒,没有密闭。因此厂房各处,室内空外院落墙壁到处都是粉尘,屋顶红瓦也成白色,严重情况不须赘述。
This article based on quartz mills production environment, labor brother, the number of dust particles in the factory, the physical examination of workers and the classification of 102 cases of silicosis photographs for preliminary analysis. The production process and the general situation of large quartz, artificially smashed with a hammer and then sieved. Iron screen with a rope hanging beams, one end of the sieve with a wooden handle, hand shaking, the first pass is coarse sieve, the larger particles to re-smash, sieve under the weight of capital. The second time is fine sieve, the powder and particles separated, particle size, according to production needs. There is also a small machine mill, often not open, little effect, the machine mill in another stifled, not closed. Therefore, throughout the plant, the indoor and outdoor courtyard walls are littered with dust, red roof tiles into white, serious cases do not need to go into details.
