Hi souliyas, Just last week I completed a similar task successfully, so I can get started on this without any ramp-up time. Which feedstock specifics (species range, max dia/shape, moisture) and chip spec (target length class/fines) should we design to? Any constraints on drum envelope/speed and available diesel/electric ratings, and preferred No‑Stress control (hydraulic-only vs PLC/VFD)? 1) Use a modular drum with laser‑cut knife cassettes, dowel datums, and AR400 liners to speed assembly, localize wear, and scale from 30→40 TPH. 2) Standardize a baseframe with cartridge-mounted spherical roller bearings, split housings, and ISO 21940 G2.5 balance; pair VFD (electric) and pump flow control + relief (diesel) for robust No‑Stress. Action Plan: Phase 1—Requirements & sizing (SEC, torque/power, drum dia/width, knife count, tip speed). Phase 2—Concepts for diesel/electric/solar‑assist, shaft/coupling, infeed. Phase 3—Detailed CAD for tab‑and‑slot; GD&T, weld sequence, access and liners. Phase 4—FEA (drum/shaft/frame), critical speed and balance check. Phase 5—Hydraulics/controls schematics; final 3D, 2D + DXF nests, BOM; review/iterate. Best Regards, Sid
