Aggregates

Capturing process particulate is of the utmost importance in mineral processing and conversion plants. Due to the inherent thin margins this industry operates in, a filter bag must perform long term with little attention. Menardi's expertise in the aggregate industry allows the user to optimize life and productivity while reducing maintenance costs.

Asphalt
Asphalt

Process material moving through the exhaust gases of an asphalt plant are very dusty. Emissions are heavily regulated by the EPA and the baghouse is the last defense an asphalt plant has to maintain minimal emission levels. Filter bags are equally important from a production aspect, as the collected material can be reintroduced into the mix as a filler. Aramid filter bags are commonly used due to effectiveness against abrasion and temperatures to 400° F (204° C).

Cement

Keeping all the processes running, producing a quality product in a timely manner, and meeting EPA emission standards is a challenge for the cement industry. Oftentimes, when things go wrong, dust collection devices are the first suspects and there are plenty of them in cement plants. Menardi has applied filtration solutions to all areas of the cement manufacturing process, including Raw Mill, Kiln, Alkali Bypass, Clinker Cooler, Coal Grinding and Finish Mill processes.

Kaolin

Many of the baghouses in Kaolin operations are process product collectors. As such, the filter bags are vital to production and quality and efficiency is critical. Menardi has worked with process engineering and production at these plants to develop and supply filter bags that are both highly efficient to minimize product loss and long lasting to reduce production costs.

Lime

As one of man's oldest and most vital chemicals, lime production and its uses have grown with the times and continue to be one of the essential building blocks of modern industry. Because today's market must meet exacting chemical and physical specifications, the demands on lime plants are very high.
