Dust Control System Setup Workflow

Steps

1. 1

   Equipment Selection

   Match dust collector CFM rating to grinder size. Rule: collector CFM should be 1.5-2x the grinders dust port CFM requirement.

   Typical requirements:\n- Small grinder (single head): 200-300 CFM\n- Medium (3-head): 400-600 CFM\n- Large (4-head planetary): 600-1000 CFM\n- Remote/ride-on: 1000+ CFM

2. 2

   Hose Connection

   Connect hose to grinder shroud. Ensure tight seal — any air leak reduces suction dramatically. Use hose clamps, not tape.

   Pro tip: A 1-inch gap in the hose connection can reduce effective suction by 50%. Seal everything.

3. 3

   Pre-Filter Check

   Inspect HEPA filter condition before starting. Check for tears, excessive dust loading, or moisture damage. Replace if airflow is noticeably reduced.

4. 4

   Shroud Adjustment

   Adjust grinder shroud height so it barely clears the floor (1-2mm gap). Too high = dust escapes. Too low = drags and reduces grinding efficiency.

5. 5

   Test Run

   Run grinder for 30 seconds and check for visible dust escape. If dust is visible, check: shroud seal, hose connections, filter condition, and CFM adequacy.

6. 6

   OSHA Compliance Check

   Verify system meets OSHA Table 1 requirements for silica dust exposure. Document: equipment used, filter type (HEPA), and maintenance schedule.

   OSHA Table 1 requirements for floor grinders:\n- Vacuum with HEPA filter\n- Shroud around grinding head\n- Operator must not see visible dust\n- Filter cleaned per manufacturer schedule
