Cement & lime industry

FANS:
- Raw mill fans, kiln primary air fans, kiln exhausters, filter exhausters, final exhausters, grate cooler fans, clinker grate exhausters, cement mill fans, coal mill fans, separator fans.

POLLUTION CONTROL:
The production of cement requires large air volumes that become polluted during the calcining and grinding of raw materials as well as the cooling and grinding of clinker. In the control of particulate emissions from these processes, fabric filters continue to gain popularity over electrostatic precipitators due to their ability to control particulate in a more consistent fashion.
Recently, it has become popular to incorporate all of the various emissions points into one single particulate collection system, complemented by an evaporative gas conditioning tower for temperature reduction and a powerful induced draft fan. Boldrocchi Ecologia is capable of supplying and installing particulate control systems, assembled from components entirely designed and engineered according to our own technology, respected for its efficiency, reliability and value.

Boldrocchi Ecologia applies newly designed bag filters and electrostatic precipitators for purifying process smoke from cement end lime kilns. Many slakes, clinker coolers, screening systems, product ensilage and loading systems have also been equipped with high-performance dry filtration systems. When required due to the temperature of the smoke, forced-air tube nest exchangers or water fog evaporating towers can be supplied.

Operating for many years under the oscillating gas temperature conditions characteristic of vertical shaft lime kilns, Boldrocchi Ecologia fabric filters have proven themselves capable of providing high particulate control efficiency at low pressure drops. In addition to process equipment, fugitive dust from stationary sources emitted by the various materials transport systems employed in the production of Lime, are controlled by Boldrocchi Ecologia filters, whose technology has been applied successfully to difficult gases, including those with high humidity content, such as lime hydrator exhausts.
