Single-disc shot blasting machine YG series

2-wheelgroundfor metal

Overview
This floor shot blasting machine is designed for industrial surface preparation of concrete and steel prior to coating or overlay. It produces consistent CSP 3–5 profiles and integrates shot recycling and dust collection to limit media loss and airborne contamination.

Key operational notes & tips

• Blasting efficiency and pattern depend on correct control cage angle: small misalignments shift the pattern center and reduce impact energy across the working width.
• For asphalt or sticky elastomeric residues, increase travel speed to minimise shot blinding on separators and reduce media coating.
• Inspect blade wear daily and replace the full matched blade set when thickness reaches ~2/3 of original to avoid bearing unbalance.
• In high-humidity sites purge the dust collector hopper each shift to prevent moist dust crusting and premature filter failure.

Blast wheel, blades & abrasive recycling
Manufacturer-fitted high-chromium cast blades (Cr12MoV) are specified for high RPM operation (~2800 RPM) with expected blade-set life of approximately 150–180 hours under continuous use. The rebound chamber uses Mn12 manganese steel liners and a labyrinth seal geometry to direct ricocheting media into a cyclone separator, achieving ~99.5% air-wash separation efficiency and reducing media top-up frequency.

Maintenance & best practices

• Keep media clean: remove contaminated shot containing slag, stone or debris to prevent accelerated wear of blades and liners.
• Monitor dust collector airflow (CFM): reduced flow allows dust accumulation in the rebound chamber, degrading shot trajectory and productivity.
• Replace blade sets in matched groups and verify dynamic balance to protect bearings and spindles.

FAQ (selected)

• Uneven blast depth on one side — check perimeter rubber seals for wear or tears and re-align the control cage scale plate.
• Maximising liner and blade life — use clean, appropriate-size media; contaminated or stony media drastically increases wear.
• Can it remove >5 mm thick mortar? — Shot blasting is effective for laitance and thin coatings (CSP 3–5). For >5 mm bulk material, remove with a scarifier first and finish with the shot blaster.
