Is there a risk of dust from small fish food pellet making machines?

The dust hazards from floating fish feed extruder machines manifest primarily in two dimensions: health risks and safety hazards. Regarding health, feed ingredient dust (such as cornmeal, soybean meal, and fishmeal) contains a large number of fine particles. Long-term inhalation by operators can lead to dust accumulation in the lungs, causing pneumoconiosis. High-protein dusts like fishmeal can also trigger allergic reactions, leading to symptoms such as itchy skin and asthma. Some dust may also contain mycotoxins, further exacerbating health risks. In terms of safety, when the dust concentration in the air reaches a certain range (the explosion limit for feed dust is 40-500 g/m³), it can explode upon contact with an open flame or static sparks generated by equipment operation, causing serious injuries and equipment damage. Furthermore, dust accumulation on moving parts of the equipment can affect heat dissipation and operational accuracy, accelerating equipment wear and creating a vicious cycle of "dust pollution - equipment damage - escalating risks."

Dust control requires a triple defense line: source control, process collection, and individual protective equipment. For source control, a small floating fish feed machine with a built-in dustproof design is selected, and sealing devices are installed at the inlet and outlet to reduce dust spillage. A closed-loop circulation system is used in the raw material crushing process to prevent dust diffusion. For process collection, a centralized dust collection system is installed in the pellet mill production area. Dust generated at the inlet and outlet is collected by a dust collector using a pulse bag filter, achieving a dust removal efficiency of over 99%. Dust around the equipment and on the ground is cleaned regularly to prevent accumulation. For personal protective equipment, operators are required to wear dust masks (KN95 or higher recommended), and the mask filter is changed every 2 hours. Clothes are washed and showered promptly after work to avoid dust residue. In addition, regular health checks are conducted for operators, with an annual occupational health examination, and health records are established. Dust concentration detectors and explosion-proof lights and switches are installed in areas with high dust concentrations to prevent dust explosions caused by static sparks, ensuring that the dust concentration in the production environment is controlled below 10mg/m³, meeting national occupational health standards.
