We are currently procuring highly customized machinery on behalf of an advanced functional polymer composites project to set up a new pilot/laboratory compounding center. We wish to purchase a highly customized Heating & Cooling Mixer Unit (approx. 50L Hot Mixer / 100L Cold Mixer capacity).
  
  This mixer will be the primary R&D tool and must be universally capable of processing standard rigid PVC, as well as extremely heavy and abrasive proprietary formulations.
  
  1. MATERIAL CHARACTERISTICS (Critical for Machine Design):
  
  The machine must handle dynamic changes in recipes, including our heaviest "Dry-Blend" formulation:
  
  
  Base Polymer: Rigid rPVC flakes/powder (K-value 57-60).
  
  
  Metals: Recycled Aluminum flakes/powder (up to 15%).
  
  
  Fillers: Heavy mineral oxides and silicates (up to 30% / high abrasiveness).
  
  
  Liquids: Soybean oil (ESBO) and liquid plasticizers (DOTP).
  
  
  Bulk Density Note: Due to the heavy oxides and metals, our worst-case mixture has a high bulk density (approx. 1.0 - 1.2 kg/L).
  
  2. REQUIRED CUSTOMIZATIONS & UPGRADES:
  
  A standard PVC mixer will not survive these abrasive recipes. We strictly require the following upgrades:
  1
  
  
  Extreme Wear Resistance: The hot mixer blades (paddles) and the inner wall/bottom of the hot mixing pot MUST be treated with Tungsten Carbide (or an equivalent highly wear-resistant bimetallic coating).
  
  
  Upgraded Motor & Drive: The hot mixer requires an oversized, heavy-duty motor with a premium frequency inverter (ABB, Siemens, or equivalent) to provide massive starting torque for the heavy mineral mass without stalling.
  
  
  Active Degassing System: The hot mixer lid must feature an active exhaust/vacuum venting system to effectively remove moisture from recycled minerals and outgassing.
  
  
  Automated Liquid Dosing: A precision liquid injection system for ESBO/DOTP oil (injected directly into the vortex at elevated temperatures).
  
  
  Precise Temperature Control: Dual PT100 sensors and highly responsive pneumatic discharge valves to prevent shear-heat degradation of the aluminum/PVC mix.
  
  
  Dust & Explosion Safety (ATEX-ready): As we may occasionally test fine dehydrated organic powders, the mixer seals, venting, and electronics must meet basic anti-dust/explosion safety standards.
  
  3. REQUESTED INFORMATION:
  
  Please provide a comprehensive quotation including:
  
  Technical Data Sheet (TDS) and layout drawing of the proposed machine.
  
  Specific details of the anti-abrasion treatment provided for the blades/pot.
  
  Price based on FOB or DAP Koper (Slovenia).
  
  Estimated manufacturing lead time.
  
  We are looking for a reliable machinery partner capable of engineering robust solutions for long-term scaling. We look forward to your technical proposal.
