Air filtration for industrial minerals treatment
Industrial minerals are present everywhere. They are essential for many manufacturing processes, but highly pollutant at the same time and very harsh on the environment. Air filtration solutions are a key part of its treatment process to control emissions and ensure an optimum operational performance.
Reducing the impact on the environment while improving operational performance
Cement, coal, arid, clays, and other minerals need to be treated to produce the raw material that will be used in many secondary industrial processes. Sometimes these processes’ demand an extremely specific micron rating and therefore the milling and screening processes these minerals must go through usually generates a very high dust concentration.
Not only milling, but every operation carried out since the reception of the material at the facility until its final transformation and packing create higher volumes of dust emissions than any other industry. Environmental impact must be controlled, but also product recovery can prevent additional costs through lost product.
Air filtration becomes strategic due to the presence of many collection points, but also to ensure satisfactory production performance, especially in those operations where unplanned stops can result in significant economic losses.

Dust collection with high focus on safety
Certain industrial minerals such as coke can be highly explosive, therefore the safety regulations are one of the most demanding of all industries, not only in terms of the emissions, but also to what’s relative to the ATEX guidelines. Explosive gases may be present as well creating an explosive atmosphere inside and outside the dust collector ATEX compliance for explosive gas and dust is a necessity. ATEX zone 01/21 and ATEX zone 02/22 classifications are common in such an industry.
Filtration media in this industry also plays a key role when acting as process filters with special requirements so that they meet the extreme conditions in temperatures (between 100º and 200ºC). Thermal insulation in specific applications to ensure filtration media quality, avoiding hydrolysis problems and increasing the safety for the process and operator.

Air filtration for high dust concentrations
The entire industrial minerals treatment process comprises several operations with high environmental impact. Arid materials are unloaded into eco-hoppers, silos, or any other reception point to be moved to conveyors for transportation to the mills that will alter the size of the product for final processing. Tons of dust with a small particle size are emitted and its collection becomes essential both for preserving the environment and workers health.
