Grizzly and Debris Scalper
Purpose
Remove rocks, roots, branches, trash, and gross oversize before fine classification or metering.
Operating concept
Fixed or vibrating bars create a first-pass opening; accepted material falls to the process path while rejects move to a visible, separately contained chute.
Key assemblies
replaceable bar deck; vibration drive if used; reject chute; accepted- material chute; spray/dust control; access guards; inspection camera; cleanout tool points
Operating sequence
feed documented material → spread across deck → pass acceptable fraction → divert oversize → record reject rate → isolate before clearing → dispose or retain rejects
Instrumentation
oversize/reject indication; sample point; conditioned-output rate
Safeguards
contain dust and splash; isolate stored energy; retain representative material sample
Failure modes and mitigations
pinch/crush points; flying debris; deck blinding; hand clearing; incorrect opening size
Variants
fixed grizzly; vibrating bar deck; finger screen; wet scalper; folding mobile deck
Validation gates
particle-distribution check; foreign-object challenge; dust/splash review; cleanout verification
Claim boundary
CLAIM BOUNDARY: No certified design, validated recipe, performance guarantee, regulatory approval, or authorization for uncontrolled-fire use is represented.
Unverified concept for qualified research. Not certified equipment, not a validated formula, not fabrication instructions, and not authorization for active-fire use. Individual conventional components are not claimed as separately invented.
