Sustaining Growth: Bag Filters for Kenya’s Cement and Construction Boom from ClipOn

Africa’s fastest-growing infrastructure is in Kenya, where the construction projects for Lamu Port, Special Economic Zones, and a large number of housing units are shaping the boom. The construction industry is thus highly dependent on the domestic cement industry, the major production bases of which are located in Nairobi, Mombasa, and Athi River. Cement manufacturing is the biggest contributor to dust problems due to high dust emissions from operations such as quarrying, grinding, and kiln exhaust.

ClipOn is the supplier of solid, high-efficiency filtration solutions engineered specifically for Africa’s harsh industrial environments. We are well aware that cement producers in Kenya are obliged to meet the ambient air quality standards set by the National Environmental Management Authority (NEMA) locally, and they must maximize operational efficiency given the highly competitive market. Our target is to provide the cement manufacturers with the most efficient, reliable Bag Filters and dust collectors designed for the very specific high-temperature and unique dust chemistry encountered in the process.

The Challenge: High Efficiency in a High-Volume Industry

The cement manufacturing process is characterized by continuous operation and/or large volumes of dust at multiple points; therefore, filtration systems must be not only effective but also resilient.

1. Kiln and Clinker Cooler Dust Control

The highest temperature and most important filtration point is the cement kiln particle emissions and the clinker cooler system. The flue gases contain fine cement kiln dust (CKD) that needs to be filtered at high temperatures.

ClipOn Solution: We supply special high-temperature filter materials, including Aramid (Nomex®) or Fiberglass, with protective PTFE finishes. These constructions are critical for overcoming the thermal peak and chemical attack from SO_x, thereby enabling the Bag Filters to remain structurally sound and effective during 24/7 kiln operation.

2. Complying with NEMA Emission Standards

Due to the stricter emission limits that Kenya has imposed on air pollution in industrial zones, the cement plants have no choice but to adopt more modern pollution control methods rather than the old, unreliable ones they had. The switch to new Bag Filters is necessary to achieve emissions considerably lower than the limit set by the authorities.

The ClipOn Benefit: Our Pulse-Jet Bag Filters deliver high-efficiency operation, which is essential for continuous filtering, so they actively capture particulate matter (PM_{10} and PM_{2.5}), and our customers achieve long-term environmental compliance.

3. Material Loss and Efficiency

In cement production, dust is a vital input. The non-performing filtration system is the reason for the loss of CKD, the product that represents the company’s economic benefit.

ClipOn Solution: The high-efficiency Bag Filters both clean the air and recover large quantities of CKD for reuse. The recovered material can be safely reintroduced into the process stream, thus converting the compliance cost into a material recovery benefit.

ClipOn’s Targeted Bag Filter Solutions for Kenyan Cement Plants

We address the primary dust-generating points in the cement manufacturing process with custom, robust components.

1. Raw Grinding and Material Handling

Application: Dust filtration from crushers, raw grinding mills, and transfer points with heavy dust and lower temperatures.

Filter Choice: Polyester needlefelt bag filters of medium type are usually used in large Pulse Jet Baghouses where low-temperature, high-volume dust loading is handled efficiently and continuously.

2. Silo and Bin Vent Filters

Application: The focus is on venting small, high-concentration dust plumes during the pneumatic filling of cement silos and storage bins.

Filter Choice: Silo Bin Vent Filters are the tiny, Integrated ones that handle the air exiting the silo when it is being filled with cement. This type of treatment requires the highest efficiency in media use and safe removal of pressure buildup, which can damage the silo and lead to fugitive emissions.

3. Customization for the African Climate

The humid, variable seasonal weather in Kenya causes fines like CKD to cake on or “blind” standard filter media. ClipOn offers special finishes, such as PTFE membrane laminates, that create a slick surface, allowing the dust cake to release cleanly and quickly during the cleaning pulse. This prevents high differential pressure and maintains airflow stability, which is essential for uninterrupted production.
