Pulse Pleated Long Filter Cartridge for Cement Plants Overview

Pulse pleated long filter cartridges are engineered for industrial environments with high dust concentrations, such as cement plants, power generation facilities, and mining operations. These advanced filtration components are specifically designed to retrofit bag dust collectors into high-efficiency cartridge dust collectors or to be integrated into new pulse jet dust collection systems. Their robust construction and optimized pleat geometry deliver up to 300% more filtration area compared to traditional filter bags of the same diameter, significantly improving dust removal efficiency and extending service life.

Featuring polyurethane end caps that are fully compatible with BHW imported filter cartridges, our pulse pleated cartridges offer a seamless replacement solution. Available in two primary mounting configurations — top-load and bottom-load — they accommodate a variety of dust collector designs. The connection plate options include polyurethane terminals, iron terminals, and three-lug (three-claw) connections, ensuring secure and reliable sealing under demanding operating conditions. This versatility makes them ideal for upgrading existing systems without major structural modifications.

Standard Structural Features

Our pulse pleated long filter cartridges are built with precision-engineered components to maximize performance in cement plant applications. Key structural features include:

• Filter Media Options: High-quality polyester fiber, composite fiber, polyester/glass fiber blends, or multi-layer synthetic media — selected based on dust characteristics and operating temperature.
• Shallow Pleat Design: Optimized pleat depth ensures superior pulse cleaning effectiveness, preventing dust bridging and maintaining low pressure drop over extended periods.
• Strong Filter Media with High Efficiency: Robust media construction withstands repeated backwashing while achieving ultra-low emission levels (typically below 10 mg/Nm³).
• 3x Filtration Area: Compared to equivalent diameter filter bags, the pleated design delivers triple the filtration surface area, reducing the number of cartridges required and lowering capital costs.
• Top Opening / Bottom Seal: Easy installation and removal from the clean air plenum, minimizing maintenance downtime.
• Galvanized Anti-Rust Metal Components: All metal parts are hot-dip galvanized for corrosion resistance in humid or chemically aggressive environments.
• Flange Multiple Installation Methods: Accepts various flange styles (round, square, or custom) for flexible integration with existing ductwork and housing.
• Rubber Seal (Optional): Upper end cover with upper and lower face seals ensures positive sealing and prevents dust leakage during pulse cleaning.

Filter Material Selection & Technical Options

To meet specific application requirements, our pulse pleated cartridges are available in a range of filter media treatments. Each option is engineered to optimize performance under different dust loads, temperatures, and chemical exposures:

• RH2 Standard Polyester Fiber (White or Black): Economical choice for general dust collection with good thermal stability up to 130°C (266°F). Suitable for cement, grain, and woodworking industries.
• RH2A Flame Retardant Treated Polyester Fiber: Enhanced fire resistance for applications involving combustible dusts (e.g., coal, metal powders). Meets UL 900 Class 2 standards.
• RH2B Oil and Water Resistant Treated Polyester Fiber: Hydrophobic and oleophobic finish repels moisture and oil mist, ideal for cement plants with high humidity or chemical additives.
• RH2CD Anti-Static Treated Polyester Fiber: Conductive media dissipates static charges, preventing spark generation in explosive dust environments (e.g., flour mills, pharmaceutical plants).
• RH2F Coated Polyester Fiber: PTFE or ePTFE membrane laminate provides superior surface filtration with extremely low pressure drop and excellent release of sticky dusts.

The combination of these material options with the shallow pleat design ensures that our cartridges deliver consistent performance across a wide range of industrial applications, from cement clinker cooling to fly ash collection in power plants.

Common Models, Sizes, and Customization

Our pulse pleated long filter cartridges are offered in a standard diameter range with adjustable length to fit most dust collector housings. The following are the most frequently requested sizes, each available in lengths from 600 mm to 2000 mm:

• 120 mm × [600–2000 mm] — Compact design for space-limited retrofits
• 146 mm × [600–2000 mm] — Industry-standard size for high-flow applications
• 150 mm × [600–2000 mm] — Optimized for bag-to-cartridge conversions
• 153 mm × [600–2000 mm] — Direct replacement for many European OEM systems
• 160 mm × [600–2000 mm] — Heavy-duty option for cement kiln dust
• 162 mm × [600–2000 mm] — High-efficiency alternative for fine dust
• 200 mm × [600–2000 mm] — Maximum filtration area for large-scale collectors

For custom requirements, we can produce non-standard diameters, lengths up to 2500 mm, and special end cap configurations (e.g., stainless steel, aluminum, or rubber gaskets). Please contact our engineering team to discuss your specific dust collector specifications.

Primary Application Industries

These pulse pleated long filter cartridges are engineered for high-dust-concentration environments where reliable performance and long service life are critical. Their primary applications include:

• Cement Plants: Dust collection at crushers, raw mills, kiln feed systems, clinker coolers, and cement grinding circuits.
• Top Recycling / Material Handling: Recovery of fine powders and granules in recycling facilities, including construction debris processing.
• Mixing Stations / Concrete Batch Plants: Capture of cement dust and aggregate fines from silo vents, mixers, and conveyor transfer points.
• Power Plants: Fly ash collection from coal-fired boilers, especially where pulse-jet cleaning is preferred over reverse-air systems.
• Casting & Foundry Operations: Control of silica dust, sand, and metal fumes from shakeout, sand reclamation, and grinding stations.

By upgrading to our pulse pleated long filter cartridges, industrial operations can achieve higher filtration efficiency (99.9%+ on submicron particles), lower energy consumption due to reduced pressure drop, and compliance with strict environmental emission regulations. The shallow pleat design also minimizes dust build-up and requires less frequent cleaning cycles, further reducing operational costs.
