In industrial and agricultural settings, productive dust is generated as fine solid particles that can remain suspended in the air for extended periods. During the production and handling of cement, workers are frequently exposed to large amounts of cement dust. Without proper protective measures, this exposure can pose serious health risks. Therefore, continuously improving working conditions, ensuring employee safety and health, and promoting safe and civilized production are essential steps in achieving production goals and reflecting the quality of corporate management.
First, dust can be categorized into different types. Inorganic dust includes metal dust (such as aluminum, iron, tin, lead, and manganese), non-metallic mineral dust (like quartz, asbestos, talc, and coal), and artificial inorganic dust (such as cement and glass fiber). Organic dust comes from plant or animal sources, while synthetic material dust is commonly found in plastic manufacturing, which contains various additives like fillers, plasticizers, and stabilizers.
Second, exposure to dust occurs in various work environments. In construction and industrial sites, workers often come into contact with substances such as free silica, quartz, limestone, clay, volcanic ash, shale, iron powder, coal, slag, gypsum, sand, and diatomite.
Third, the health hazards of dust vary depending on its properties. Soluble toxic dust can enter the respiratory system and be absorbed into the bloodstream, causing poisoning. Radioactive dust may cause radiation damage, while hard particles can irritate the eyes, leading to corneal opacity or conjunctivitis. Dust can also block sebaceous glands, causing skin issues like acne or dermatitis. Additionally, dust entering the ear canal can mix with earwax, forming cerumen.
The most severe health effect of dust is on the respiratory system, leading to conditions such as upper respiratory inflammation, pneumonia, lung granuloma, lung cancer, and pneumoconiosis. Pneumoconiosis, caused by long-term inhalation of dust, is a widespread and dangerous occupational disease characterized by fibrosis in the lungs.
To prevent these dangers, several strategies should be implemented: process improvement and technological innovation to reduce dust generation; wet operations to suppress dust and lower airborne concentrations; enhanced ventilation systems to remove contaminated air and supply fresh air; sealing dust sources to minimize dispersion; personal protective equipment such as masks and goggles; regular monitoring of dust levels and health check-ups for workers; and education on safety practices, including hygiene and awareness of potential risks.
By adopting these measures, companies can create safer working environments and protect their employees' well-being effectively.

The liquid inlet/outlet adopts a ceramic hard seal structure, the liquid is in contact with the ceramic throughout the entire process, and does not touch the stainless steel jacket. The ceramic parts of the liquid inlet/outlet can be disassembled for cleaning and disinfection like the ceramic plunger rod and the ceramic reversing rod, which completely solves the problem of cleaning the dead angle between the steel jacket and the ceramic.
