Labor protection and health care in small cement plants

With the continuous improvement of the labor protection and health care of small cement plants, the vast number of new houses have been built in cities and rural areas, and cement is the main building material. The demand is increasing. In order to adapt to this situation, the majority of townships and towns have established cement plants and become the main township enterprises. These small-scale cement plants produced large cement, which met the needs of the majority of rural housing construction and eased the contradiction between supply and demand of cement. Township small cement plant equipment, production: poor environment and working conditions, there are many health problems, it is worth serious labor protection and health care to protect the health of employees and the smooth development of production.
There are two main problems in the small cement plant: First, the workers are harmed by mixed dust, causing cement pneumoconiosis; second, heat stroke is prone to heat stroke. Therefore, cement plants should focus on solving these two problems. Prevention of cement pneumoconiosis: Cement pneumoconiosis is an occupational disease caused by long-term inhalation of cement dust by cement workers in the production process. Cement is a synthetic amorphous silicate that produces a lot of dust during the production of cement. The raw materials for the production of cement vary according to the type of cement; there are limestone, clay, shale, iron powder, slag, coal ash, and gypsum. Its production process is mainly divided into two parts: raw material and clinker. Raw meal production includes the crushing and drying of various raw materials.
This process produces more dust and is the most dangerous. This is because the dust produced during the production of raw meal contains more free silica. The size of the dust hazard is mainly determined by the amount of free silica in the dust. Clinker production includes calcining and cement packaging, transportation, etc. Although a large amount of dust is also produced, it is less harmful because it contains less free silica. Workers in other processes are mainly exposed to mixed dust and cement powder, which is also quite harmful. Cement pneumoconiosis generally has a long onset time, slow progress, and insignificant clinical symptoms. It is mainly due to changes in x-ray chest radiographs. This is one of the important basis for the diagnosis of cement pneumoconiosis. In addition, long-term exposure to cement dust can also have a stimulatory effect on the human body, mainly irritating the respiratory tract and skin, often appear chronic bronchitis, bronchial asthma or allergic dermatitis, sometimes eye conjunctivitis, corneal opacity, nasal mucosal ulcers and other diseases.
