High-Abrasion Dust Collection System for Casting Shot Blast & Grinding Rooms - LEFILTER Solution

Product Introduction:

LEFILTER's system for foundry cleaning operations is built to endure extreme abrasion. For shot blasting rooms, we supply heavy-duty cyclones paired with final-stage cartridge or bag filters. The cyclone is engineered with thick, wear-resistant liners (ceramic or AR steel) to handle the violent stream of metallic abrasive and sand. The final filter utilizes anti-static, abrasion-resistant filter media with a robust pleat construction. For centralized grinding stations, we provide high-static pressure fans and ductwork designed for heavy particulate, ensuring dust is effectively transported from multiple workstations to a central, high-capacity collector.

Application Area:

This system serves the post-casting cleaning departments in foundries, including shot blasting cabinets/rooms for descaling and surface preparation, and grinding stations for removing gates, risers, and finishing castings. The dust generated is a highly abrasive mixture of metallic fines (iron, aluminum), spent silica sand, and binder residues. This dust rapidly wears out standard equipment, clogs ducts, and creates a hazardous respiratory environment (risk of silicosis). Effective dust control is essential for equipment longevity, worker safety, and maintaining a clean, productive workspace.

Our Solution:

LEFILTER’s design philosophy for foundry cleaning focuses on durability and source capture. For blast rooms, our multi-stage system ensures >99% of the abrasive is recovered by the cyclone for reuse, dramatically reducing media consumption, while the final filter polishes the exhaust air. Ductwork features long-radius elbows and abrasion-resistant boots at impact points. For grinding areas, we design capture hoods integrated into workbenches or flexible extraction arms placed close to the grinding wheel. The centralized collector features heavy-duty, continuous-duty fans and automatic cleaning systems. This integrated approach significantly extends the life of your equipment, creates a safer and more visible working environment, reduces abrasive and product loss, and ensures reliable compliance with occupational exposure limits.
