Article 14: Corresponding effective protective measures must be taken in workplaces where there are dangers such as high temperature, low temperature, humidity, lightning, static electricity, etc. Chapter 5. Quality Management of Raw Materials and Fuels Article 15. Reserves of raw materials and fuels should be stored separately according to different varieties and qualities, and used in proportion according to production technology requirements. Raw materials should be stacked and weathered for more than four months. Article 16. The quality of raw materials and fuel (plasticity index, density, moisture content, calorific value, etc.) meets the production technical requirements and is blended and used according to laboratory testing proportions. Article 17: Coal gangue and shale should be aged after being crushed, pulverized, and stirred. The aging time is determined by factors such as the nature of the raw materials, production varieties, and output. Article 18: Conduct chemical analysis of raw materials before putting them into production. During normal production, it should be inspected once a year. When the ratio and source of raw materials change, it should be inspected in time. Article 19: Coal gangue and shale should reach a certain fineness after processing. Coal gangue﹤2.0mm, among which:﹥2.0mm but﹤3.0mm should be 5;﹤0.5mm should be above 60. Shale﹤2.5mm, among which:﹥2.5mm should be﹤5,﹤0.5mm should reach more than 60. During normal production, the particles and proportions of raw materials should be inspected every six months. When the proportions and raw materials change, they should be inspected in time. Article 20. The plasticity index, drying sensitivity coefficient, natural moisture content, shrinkage rate, calorific value and other quality indicators of raw materials and fuels should be analyzed through chemical testing. Inspections should be carried out according to different varieties, dosages and lengths of time. When the source of raw materials changes, they should be inspected in time.
