Dust Extraction Unit for Battery Electrode Slitting

Product Specifications

Technical details and manufacturing context for Dust Extraction Unit

Definition

The Dust Extraction Unit is an integral part of the Battery Electrode Slitting Machine, responsible for maintaining a clean production environment by efficiently extracting fine dust and particulate matter produced when slitting battery electrode materials (such as lithium-ion battery anodes/cathodes). It prevents dust accumulation on machinery, reduces contamination risks, and ensures operator safety and product quality. The unit typically uses suction created by a fan or blower to draw dust-laden air through intake hoods positioned near the slitting blades. The air passes through filtration systems (e.g., cartridge filters, HEPA filters) that capture dust particles, while clean air is exhausted or recirculated. Collected dust may be automatically discharged into containers. Constructed with stainless steel housing and ducting, aluminum structural frames, and filter media such as polyester or PTFE, the unit is designed for durability and efficient filtration. Key parameters include an air flow rate of 500–2000 m³/h, static pressure of 1500–3000 Pa, filtration efficiency of ≥99.9% for particles ≥0.3 μm (per ISO 16890), filter area of 10–50 m², noise level ≤75 dB(A) at 1 m (per ISO 3744), operating temperature 0–50°C, power supply 380 V AC ±10% (three-phase, 50/60 Hz, per IEC 60038), power consumption 2.2–7.5 kW, ingress protection IP54–IP65 (per IEC 60529), weight 150–500 kg, and dimensions ranging from 1200×800×1500 mm to 2000×1200×2000 mm. These values are reference ranges and must be verified for the specific model and application. The unit is intended for integration into electrode slitting lines; selection should consider dust load, duct length, and required suction at collection points. Proper installation and maintenance are essential to ensure performance and safety. Always confirm model-specific specifications and compliance with relevant standards with the legal manufacturer or supplier.

Working Principle

The Dust Extraction Unit operates by creating a negative pressure differential using a fan or blower, which draws dust-laden air from the slitting area through intake hoods located near the blades. The air is then directed into a filtration system, where filter media such as cartridge or HEPA filters capture fine particles. Clean air is either exhausted outside or recirculated back into the workspace. Collected dust is automatically discharged into collection containers for disposal. The efficiency of the system depends on maintaining adequate airflow and static pressure, as well as proper filter maintenance.
