Foundry is one of the most harmful and dangerous operations in the industry. Research shows that the quality of abrasive materials directly impacts occupational safety. Peeling, metal stripping, grinding, sharpening, lapping, and surface treatment generate abrasive industrial dust. This dust consists of particles of various sizes that float in the work area air and settle slowly. Constant inhalation of industrial dust can lead to occupational diseases such as silicosis, pneumoconiosis, and even cancer.
Laboratory tests have shown that fine-grained abrasive grinding wheels remove the same amount of metal at a pressure force of 6 kg as other wheels with a pressure force of 10 kg. In addition, these wheels remove 40% more metal than any of the others with the same pressure force. The dust formed during metal processing with various abrasive materials differs in size due to the ceramic aluminium oxide content (Al2O3).
We can draw the following conclusions from the conducted study:
- The quality of the abrasive material has a direct impact on occupational safety.
- The use of modern materials in grinding makes it possible to increase the speed of surface treatment by several times (2–3 times), improving labour productivity and reducing the duration of the negative impact of industrial dust on the operator when performing the same amount of work.
- Modern abrasive materials can lower the concentration of dust in the workplace, make the dust fraction less harmful, reduce the duration of dust exposure to the worker, and increase the worker’s productivity.
Controlling industrial dust is an urgent occupational health issue, as many workers can be affected by it. Reducing dust levels in the air of the work area can improve working conditions and mitigate the risk of occupational diseases among employees. It can also lead to economic benefits for the company by reducing the cost of medical treatment and workers’ compensation.
The proposed solution helps to decrease dust concentration in the workplace, makes its fraction safer, reduces the employees’ time of exposure to dust, and increases labour productivity.
