Product Overview

Core Product Competitive Advantages

1. High-Precision Hardened Gear Transmission System
   The reducer core gears are forged from premium alloy chromium steel with precision CNC grinding and heat quenching treatment, imported high-standard assembly process ensures ultra-low abrasion and stable long-term transmission efficiency. Running noise is drastically suppressed compared with ordinary gearboxes, and overall power consumption is reduced for continuous daily operation.

   2.Dual Independent Heating & Water Cooling Temperature Control

   Separate electric heating modules and full-circulation water cooling channels are embedded inside the mixing chamber and rotor bodies. PID intelligent temperature controllers support free switching between heating and cooling modes, with adjustable working temperature ranging from ambient up to 300℃. Temperature fluctuation is tightly controlled to avoid scorching of heat-sensitive elastomers and uneven plasticization of filled plastics.

   3.Wear-Resistant W-Type Cast Mixing Chamber

   Integral cast W-shaped mixing cavity with thickened wall structure greatly enhances anti-abrasion performance. All inner contact surfaces are surfacing welded and mirror hard chrome plated, extending service life 1–2 times over standard mixing tanks. The sealed cavity design prevents powder leakage of carbon black, ceramic powder and magnetic powder, lowering raw material waste and workshop pollution.

   4.Optimized Four-Wing Tangential Rotor Design

   Custom asymmetrical four-wing rotors with fixed 1:1.17 front-rear speed ratio create powerful shearing, folding and kneading force. Single mixing cycle only takes 5–7 minutes, 3x faster than conventional two-roll open mills. Rotor base material is 38CrMoALA alloy steel with integral nitriding treatment, surface hardness reaches HRC58–65 for long-term filler abrasion resistance.

   5.Dry Mechanical Shaft Seal & Easy Color Change

   Adopts dual-stage anti-leakage sealing structure with imported fiber resin sealing rings, effectively blocking fine powder overflow at rotor shaft ends. No frequent disassembly required when switching different color formulas; the tilting discharge design allows full cleaning of the mixing chamber within a short time, reducing cross-contamination risks between batches.

   6.Automated Hydraulic Pressurization & Tilting Discharge

   Vertical pneumatic hydraulic top ram applies stable constant pressure on materials during kneading to boost filler dispersion efficiency. 110°–135° motor-driven tilting unloading mechanism completely empties mixed stock without residual buildup. Operators can switch between manual, semi-auto and full-auto program modes according to production demands.

7. Integrated Low-Maintenance Frame Layout
   Whole machine heavy steel welded base with universal moving casters for flexible workshop layout adjustment. Central forced circulation lubrication system continuously supplies oil to gears and bearings during operation, eliminating daily manual oil refilling and lowering long-term maintenance labor costs.

Standard Automated Mixing Operation Workflow

1. Formula Parameter Setup
   Input target kneading temperature, total mixing duration and top ram pressurization holding time on the central control panel, save custom recipe for one-click recall in subsequent batches.
2. Raw Material Feeding
   Lift the hydraulic feeding gate, sequentially add base rubber/plastic pellets, color masterbatch, carbon black and functional fillers into the sealed mixing chamber, then lower and lock the top ram.
3. Constant Pressure Kneading CycleDual rotors start differential rotation under stable hydraulic pressure; integrated heating or water cooling runs synchronously to maintain preset material temperature for scheduled shearing and homogenization.

4.Automatic Discharge Trigger

Once the set mixing countdown finishes, the machine lifts the top ram automatically, the mixing chamber tilts to preset angle to fully unload compound stock into receiving containers.

5.Chamber Cleaning & Batch Switch

Reset the tilt cylinder back to horizontal position, wipe residual compound from rotors and cavity walls; replace sealing gaskets if switching high-pigment formulas to avoid color cross-over.

6.Shutdown Maintenance

Cool down the mixing chamber to below 60℃, cut off main power, check lubricant tank level and gearbox oil volume for the next production shift.
