Vertical Ring Die Pellet Mill: Die stationary, pressure rollers rotating; vertical feeding, more direct and smooth.
Old Flat Die Pellet Mill: Die rotating, pressure rollers stationary; vertical feeding (direct), but rotating die causes secondary beating of pellets, impairing formation.
New Flat Die Wood Pellet Mill: Die stationary, pressure rollers rotating; vertical feeding (equally direct/smooth), suitable for soft fluffy biomass. However, flat die structure limits diameter, so only small models for small clients.
Vertical Ring Die Pellet Mill: Vertical structure with ring die, better heat dissipation.
Flat Die Pellet Mill: Enclosed pressing chamber (material above, hot finished pellets below); poor heat dissipation, shortening bearing life and wear parts' lifespan.
Vertical Ring Die Pellet Mill: Double-layer die design (multi-use or dual-use), cutting costs and boosting efficiency.
Flat Die Pellet Mill: Only single-plate design.
Vertical Ring Die Pellet Mill: Independent discharge system, no impact on pellet production.
Flat Die Pellet Mill: Relies on main power for discharge; high rotation speed damages hot pellets.
