Inside the Machine — Core Components

Eight engineered subsystems that make this machine production-grade. Each component is sourced, built, and tested for industrial duty cycles.

1. Virgin Material Inlet (Side Flange + Anti-Bridge Cone)

Function

Feeds new virgin EPS beads into the mixing chamber from the upstream pre-expander or material silo. Anti-bridge cone design prevents bead bridging that would interrupt the recycled-to-virgin ratio.

Engineering Details

DN150 mm welded steel side flange with bolt-pattern compatible with pneumatic conveying duct OR auger discharge. Anti-static powder coating prevents bead clumping in dry climates. Optional load cell on inlet conveyor for gravimetric ratio control (premium accuracy plus or minus 1 percent).

2. Recycled Material Inlet (Mirror-Side Flange)

Function

Feeds the regrind beads from the upstream De-duster (Stage 2) into the chamber on the opposite side from virgin material. Symmetric inlet placement ensures balanced flow into the agitator center.

Engineering Details

Mirror-image DN150 mm steel flange on the opposite chamber side. Inlet position 90 degrees offset from virgin inlet ensures two material streams meet at the agitator vortex for fast homogenization. Compatible with -2 to -5 kPa pneumatic conveying from upstream De-duster.

3. Mixing Chamber + Multi-Blade Agitator

Function

High-aspect-ratio vertical chamber (5.5 m tall) houses a multi-blade agitator that creates a vortex flow ensuring uniform mixing of virgin and recycled beads — homogeneous output prevents density variation in downstream molded products.

Engineering Details

Welded carbon steel chamber, anti-corrosion epoxy lining. Central agitator shaft rotates 4-8 angled paddle blades at 60-100 rpm (slow speed prevents bead breakage). Achieves homogeneous mix in 3-5 minutes per batch. Internal baffle plates eliminate dead zones. Inspection window for visual mix verification.

4. Drive Shaft + Heavy-Duty Bearing System

Function

Heavy-duty drive shaft transfers torque from the top-mounted motor + reducer down to the agitator blades through a heavy-duty bearing system. Twin-bearing support ensures shaft alignment over 5+ meters of vertical span.

Engineering Details

Ø80-100 mm precision-machined alloy steel shaft (42CrMo, quenched + tempered HRC 28-32). Twin SKF or NSK spherical roller bearings (sealed for life, grease-lubricated) absorb radial + thrust loads. Mechanical seal at top prevents bead leakage. Bearing housing cast steel with replaceable wear sleeves.

5. Drive Motor + Ratio Control System (4.35 kW VFD + PLC)

Function

High-efficiency motor + variable-frequency drive enable programmable mix ratio (0-100 percent virgin to recycled blend) — operator sets the recipe via HMI and the PLC controls inlet feeders accordingly for the entire production run.

Engineering Details

YE3 IE3 motor 4.35 kW (5.8 HP), 380V / 50Hz / IP55, F-class insulation. ABB or Schneider VFD with sensorless vector control adjusts agitator speed 30-120 rpm. Siemens S7-1200 PLC + 7-inch Weintek HMI for ratio recipes. Ethernet/IP integration with upstream De-duster and downstream molding line. Energy-efficient operation (lowest kW per ton processed in the recycle line).

6. Discharge Outlet (Bottom DN150 + Rotary Valve Compatible)

Function

Bottom discharge outlet releases the homogeneously mixed virgin+recycled bead stream to the downstream molding line (block molding or shape molding). Sealed flange design maintains the mix integrity all the way to the molding silo.

Engineering Details

Cast steel DN150 mm (200 mm OD) flange with M10 grade 8.8 bolts and EPDM gasket airtight seal. Direct-mount to rotary airlock valve (sold separately) for pneumatic conveyor connection to downstream silo. Output throughput 30-50 m3/hour (highest in the SPH recycle line — pure mixing duty). Discharge sensor triggers low-level alarm to prevent dry-run.

What This Machine Solves

Three production problems eliminated by this machine — with engineered, measurable solutions.

The Problem 1

Recycled EPS scrap mixed with virgin beads at wrong ratio causes density variance + production rejects

How This Machine Solves It

RE900 proportional mixer auto-blends virgin + regrind beads at PLC-controlled ratio (5-30% regrind), holding final density variance under ±0.5 kg/m³.

The Problem 2

Manual scoop-mixing of beads is labor-intensive + inconsistent — small factory operators spend 1-2 hours/shift on this

How This Machine Solves It

Automated proportional mixer runs continuously without operator attention — frees up 1-2 labor hours per shift for higher-value tasks.

Working Principle

RE900 receives virgin and regrind beads in separate hoppers, proportionally blends per PLC-controlled ratio, discharges blended material to PE pre-expander.

Step 1

1. Hopper Loading

Virgin and regrind beads loaded into separate hoppers.

Step 2

2. Ratio Setting

Operator sets blend ratio on HMI (5-30% regrind typical).

Step 3

3. Proportional Discharge

Two rotary valves discharge beads at PLC-controlled ratio.

Step 4

4. Continuous Mixing

Blended beads flow to PE pre-expander hopper for downstream expansion.

Engineered Performance Advantages

Every advantage backed by measurable specs — no marketing claims without data.

Product FAQ

The questions buyers ask most often before placing an order.

What's the max regrind ratio without affecting product quality?

30% regrind for construction insulation; 20% for premium packaging; 10% for QC-critical FR-grade. Higher than 30% regrind shows visible quality degradation.

Compatible with all EPS grades?

Standard EPS, fast-cycling, graphite all work. FR-grade regrind blending requires additional ATEX-rated handling — quote separately.

Ships to 220V/60Hz?

Yes — 2-week lead time adjustment.
