Rhong Machinery Sound-proof Central Granulators Product Description
For crushing carbon fiber plates, a standard 15kW plastic central granulator will fail rapidly unless it is specifically modified with abrasive-resistant upgrades. Carbon fiber is extremely abrasive and strong, meaning standard plastic-cutting blades will dull within hours, and standard cutting chambers will erode
To process carbon fiber plates successfully and quietly, you need a heavy-duty, soundproof central granulator configured with explicit specifications.
Common Applications:
•Thick and smaller injection-molded automotive parts
• Heavy-walled ,smaller and short extruded pipes and profiles
• Smaller extruder start-up purgings and thick plastic blocks
• Smaller electronic waste housings (PC/ABS blends)

Critical Technical Specifications
To handle carbon fiber plates safely and efficiently, your 15kW (20 HP) system must feature the following structural components:

01
To handle carbon fiber plates safely and efficiently, your 15kW (20 HP) system must feature the following structural components:
Claw blades disperse the extreme impact load of fracturing carbon fiber plates, preventing rotor jams
02
Blade Material:SKD-11 or DC53 .
Standard 6CrW2Si steel will dull immediately under the abrasive friction of carbon fiber composite dust.
Dust & Material Extraction:
Integrated vacuum blower with a cyclone collector. Carbon fiber dust is conductive and toxic to breathe. A completely sealed negative-pressure extraction system is non-negotiable to protect worker lungs and prevent electrical shorts in the factory
03
Acoustic Insulation:
Full soundproof enclosure featuring high-density acoustic absorbing and reflecting layers. This reduces the harsh, high-pitched cracking noise of carbon plates down to a safe 80–95 dB operating level
04
Enclosure & Wear Plates: Hardox (or equivalent) wear-resistant liners
welded inside the cutting chamber. The flying shards of crushed carbon fiber act like sandpaper and will wear through a standard raw steel chamber
Paddle blades type rotor
Features a progressive, inclined cutting angle that behaves like a continuous scissor cut. Unlike claw or flat blades, paddle rotors distribute the mechanical load sequentially, which drastically reduces instantaneous power spikes and structural vibration when striking thick, stubborn plastics


Staggered blades type rotor
designed with a claw-type staggered blade structure optimized specifically to disperse impact loads. Their design utilizes a fixed knife retainer system that eliminates internal blade adjustment downtime.
Not Just Traditional Cyber & Immigration Firm
There are locations in the United states of america as well as ationally. The organization was established in 2000 on the basis of a small idea conceived by its promoters that was incepted.


Sourcing & Customization Checklist
When requesting quotes from industrial suppliers on platforms like Made-in-china,google,Linkedin,Facebook,
you must specify the following to the engineer:
you must specify the following to the engineer:
1."The input material is carbon fiber composite plate, not standard plastic."
2."Upgrade the rotary and stationary blades to SKD-11 or DC53 steel."
3."Add an anti-wear treatment or Hardox liners to the interior crushing chamber."
4."Include a sealed blower evacuation system with a dust filtration bag to contain conductive carbon fibers.
Would you like assistance determining the optimal rotor speed (RPM) for your plate thickness, or do you need a recommendation for a dust-filtration system to handle the carbon fiber particles?
FAQ
Q:To help narrow down the ideal machine capacity and motor sizing for your facility, could you share a bit more detail?
A: What specific type of plastic are you crushing (e.g., Polycarbonate, Nylon/PA66, ABS, or fiber-filled resins)?
B:What is your required throughput capacity in kilograms per hour (kg/hr)?
B:What are the maximum dimensions and thickness of the largest single waste piece you intend to feed into the hopper?
