INFP: High-Moisture Waste

Representative Materials: Domestic waste, aged/landfill waste, etc.

Traits: High humidity, prone to clumping, "clingy," and easily causes "mesh blinding" (clogging) when agitated.

Best Soulmates: Trommel Screens (with Triangular Discs) or Flip-Flow Vibrating Screens.

Why it works: These screens act like patient "clump-breaking" experts. 

The disc plates feature a scraping motion that "counsels" the waste to separate rather than stick together. The anti-clogging design provides that "thoughtful detail," ensuring the screen holes stay clear and never give the INFP materials a chance to huddle up.

ENFP: Light-Material Waste

Representative Materials: Industrial solid waste, light components from renovation waste, etc.

Traits: Complex composition, coarse particles, and high flow volume.

Best Soulmates: Flip-Flow Screens or Triangular Disc Screens.

Why it works: These screens are experts at "taming kites." 

They provide enough vibration to shake the light materials loose while the discs ensure they don’t "fly away." When plastic bags or fabric scraps from renovation waste meet these screens, it’s like an Extrovert finding a friend who gets all their jokes—the materials are precisely sorted into the required sizes.

ISTJ: Rigid Waste

Representative Materials: Scrap tires, waste plastics, etc.

Traits: Varied shapes and sizes, "tough bones," neither sticky nor fly-away.

Best Soulmates: Triangular Disc Screens.

Why it works: The Triangular Disc Screen is a hardcore "Quality Inspector." Its dual design of rolling and vibrating forces the waste to line up and pass through the mesh orderly. It is precise, wear-resistant, low-noise, and space-saving. Whether dealing with coarse or fine materials, it achieves "precise classification" by size.
