As a leading manufacturer from Anping County, Hebei, China, Anping County Boli Hardware Wiremesh Products Factory has been dedicated to producing high-quality filtration solutions since 1998. Our triangular filter bag made of needle felt is specifically engineered for cement plant dust collection systems, offering a robust and reliable solution for capturing fine particulates. With a fabric weight of 500 g/m² and precise dimensions of 1.5 m length × 0.8 m width, this filter bag combines excellent dust holding capacity with efficient airflow, ensuring long service life and reduced maintenance costs for your cement production line.
The triangular shape is designed to fit most pulse-jet or reverse-air dust collectors commonly used in cement plants, maximizing the filtration area within limited space. The needle felt construction provides high mechanical strength, resistance to abrasion, and stable dimensional stability even under harsh operating conditions. Whether you are handling clinker cooler dust, raw mill exhaust, or kiln baghouse applications, our filter bag delivers consistent performance.
Key Features & Technical Specifications
- High filtration efficiency – Needle felt structure captures fine particles down to sub-micron levels, meeting stringent emission standards.
- Thermal resistance – Depending on fiber selection (polyester, aramid, Nomex, etc.), the bag can withstand continuous operating temperatures from 150°C to 260°C (customizable).
- Chemical resistance – Suitable for acidic, alkaline, and organic dust environments common in cement production.
- Low pressure drop – Optimized fiber density and surface treatment minimize energy consumption.
- Easy installation & sealing – Triangular shape with reinforced top and bottom cuffs ensures airtight fit.
- Customizable options – Available in various colors, surface finishes (singed, calendered, PTFE-coated, etc.), and with different cage materials.
