Dust collection systems for cement and lime
Kleema designs, manufactures and supplies bag filters, centrifugal fans and dust capture systems for cement and lime processes. Supply can cover individual equipment, integration into an existing system or plant modernization.

Dust capture throughout the process
Crushing, grinding, screening, conveying, transfer points, silos and bagging have different dust emission sources. Capture points are defined considering the operation, openings, handled material and plant constraints.
Gas filtration for kilns and coolers
For thermal processes, filter selection considers actual gas flow, normal and peak temperatures, gas composition and moisture, dust loading, and startup and shutdown conditions. Where required, temperature control must be integrated into the design to respect the filter medium limits and assess condensation risks.
Filter, ducts, fan and discharge as one system
Filter area, gas distribution, cleaning system and dust discharge are defined for the application. Ductwork and the fan must meet the flow and pressure drop requirements of the complete system, including operating conditions and maintenance access.
Replacement, expansion and retrofit
Assessment of an existing installation considers equipment condition, operating data, available space and interfaces. Component reuse depends on technical feasibility; conversion of an electrostatic precipitator into a bag filter also requires checking structural strength and the new pressure drop.
Real application: Cimento Nassau — Itautinga
The conversion of the Itautinga clinker kiln precipitator reused the casing and hoppers, with structural adaptations, filter elements, a new cleaning plenum and a new fan. This case illustrates a retrofit scope, rather than a configuration that can be automatically applied to every plant.
Information for an engineering assessment
Send a description of the process and emission points, flow with reference conditions, normal and maximum temperatures, dust and gas characteristics, operating schedule and emission requirements. For modernization, include drawings, photos, existing filter and fan data, available space and the planned shutdown window.
