The danger of fumes and micro-dusts produced during metal polishing is known to both industry operators and the authorities responsible for diffuse emissions.<\/p>\n

In this article we present a very effective solution developed for an important manufacturing company that has expertly invested in the health of its employees and in the cleaning of the work area.<\/p>\n

Customer request<\/strong>
\nThe extraction of welding fumes<\/a> and grinding dust and polishing metals generated during the various metalworking activities, by suction close as possible to the source of pollution, as required by regulations for the safety of operators and the working environment.<\/p>\n

Issues<\/strong>
\nThe customer requires a dust suction system that guarantees working flexibility<\/strong> considering that the welding and grinding stations can work at 100% but in some periods even at 30% of their capacity. In operational terms it means designing a system that works with the same efficiency in a flow range from 29000 mc\/h to the desired reduction, without waste of electricity.<\/p>\n

From a technical point of view the challenge was above all linked to the correct suction of the polishing dust<\/strong> produced by fixed workstations that disperse micro-dust in a high-speed environment, difficult to capture using the classic systems such as suction arms or hoods.<\/p>\n

Solution <\/strong>
\nThe customized design and installation of a suction plant<\/a> with dust collection and fine polishing dust on each individual workstation, has been carried out through suction walls with lateral and upper containment, in order to optimize the flow.
\n\"parete
\nThis solution effectively contains airborne dust, protecting the respiratory tract of operators and machinery.<\/p>\n

The various suction stations are connected to each other by a network of galvanized pipes with circular cross-section, to a cartridge filter<\/a> with centrifugal fan with simple suction positioned outside the production room. An Industry 4.0 compliant electrical panel with inverter and pressure reading inside the ducts will regulate the actual suction capacity of the system and consequently the absorbed power of the fan, for maximum energy saving. <\/strong><\/p>\n

Design and development<\/strong>
\nAfter careful analysis<\/a> of the client\u2019s production needs, the contemporaneity of the work, and the production layout, our technical office has developed the project of the suction system articulated in the following points:<\/p>\n
