Description: Core filter element for pulse‑jet baghouse dust collectors. Manufactured from polyester staple‑fiber via needle‑punched process and sewn into bag assemblies, used matched with filter cages. Within corn dust‑removal systems, it intercepts corn dust and husk fragments in process airflow to achieve gas‑solid separation and meet exhaust‑gas emission requirements. It is a critical consumable spare‑part for grain‑dust‑handling equipment.
Material propertiesBase medium: Polyester needle-punched felt with good air permeability and wear resistance. Continuous operating temperature ≤130℃.
Short-term peak temperature tolerance up to 150℃. Surface can be heat-set and treated with oil-repellent & water-repellent finishing.
Well-suited for humid dust-laden corn-processing operating conditions. Working principleDust-laden airflow enters the filter bag.
Dust particles are captured on the outer bag surface while cleaned air permeates through the felt media. Once dust builds up to a set level.
Pulse-jet valves inject compressed air to dislodge surface dust which falls into the dust hopper sustaining continuous filtration capacity.
Key strengths
1. High porosity, excellent air permeability, moderate system operating resistance. Wear-resistant & fold-resistant.
Withstands continuous corn-dust erosion for extended service life. Smooth surface facilitates cake release and resists fine grain-dust adhesion.
Flexible fabrication; custom dimensions available for installation across multiple pulse-jet dust-collector models.
Excellent cost-performance; the most widely-adopted filter media for grain-processing dust-removal.
Usage Precautions- reduce long-time over-temperature operation.- Strictly stop excessive water-vapor condensation which would cause filter-bag blinding/clogging.- Set appropriate pulse-jet cleaning cycle when deploying pulse-jet cleaning systems.
