Why Choose RTM Machine?
-
Pioneering Technology
High-efficiency washing modules are engineered for consistent purity and process stability.
-
Energy Efficiency
Optimized flow, heating, and dewatering reduce energy and water usage across the full line.
-
Global Support
Engineering support includes commissioning guidance, process tuning, and long-term service assistance.
Our Standard Process Flow
A continuous 10-stage automated recycling workflow from raw baled bottles to premium rPET flakes.
-
01. STAGE
De-baling
Opens dense compressed bottle bales for steady, uniform material feed into the line.
-
02. STAGE
Trommel Screening
Separates loose dirt, sand, gravel, and heavy foreign debris before downstream processing.
-
03. STAGE
Label Separation
High-efficiency mechanical de-labeling strips PVC and OPP sleeve labels from intact bottles.
-
04. STAGE
Manual Sorting
Dedicated visual inspection conveyor for color sorting and non-PET bottle removal.
-
05. STAGE
Wet Grinding
Heavy-duty wet crusher reduces bottles to uniform flakes while introducing initial wash water.
-
06. STAGE
Sink/Float Tank
Density separation: PE/PP caps float to top while clean PET flakes sink to the bottom.
-
07. STAGE
Hot Washer
High-temperature alkaline hot wash dissolves glues, oily contamination, and organic residue.
-
08. STAGE
Friction Washer
High-speed centrifugal rotor vigorously scrubs flakes with fresh water to remove chemical residues.
-
09. STAGE
Drying System
Centrifugal spin dewatering combined with thermal hot-air pipeline lowers flake moisture to < 1%.
-
10. STAGE
Final Packing
Air-classification zig-zag separation extracts fine dust before clean flakes are bagged.
