Product Description
Type 90 Pin-type Rubber Extruder
Cold feeding, low energy consumption extruder with comprehensive after-sales service support.
Product Overview
The core of this cold-feed extruder lies in the direct plasticization of rubber compounds at room temperature. The axial thrust generated by the rotating screw, combined with the shearing action of the pins, transforms the rubber compound from solid to molten state within the barrel.
Three-Dimensional Composite Motion Plasticization
The rubber compound, under the action of the pins in the screw thread grooves, generates a three-dimensional composite motion encompassing transverse, longitudinal, and rotational movements. This effectively disrupts laminar flow and agglomeration, enhancing the kneading effect.
Pin Shearing Design
- Radial pins: Helically arranged along the barrel length, with ends close to the screw root diameter surface, disrupting the laminar flow structure
- Tangential pins: Distributed in pairs on both sides of the barrel, some employing hollow structure with built-in cooling channels for secondary vortex mixing and temperature control
Key Component Configuration
- Screw and barrel: 38CrMoAlA alloy steel with bimetallic nitriding treatment, aspect ratio 12:1 to 22:1
- Temperature Control System: Intelligent segmented temperature control with heating/cooling channels for die head, screw, and barrel, maintaining rubber temperature below 120℃
- Feeding Device: Feeding roller at rear rotates synchronously with main shaft via linkage gear for uniform rubber strip feeding
Advantages Over Hot-Feed Extruders
Simplified Process and Reduced Costs
- Elimination of Hot Refining Steps: No need for two-roll mill hot refining, simplifying production process and saving manpower and equipment investment
- Labor Reduction: Labor costs reduced by over 50%
- Smaller Footprint: More compact production line layout with less environmental pollution
Production Efficiency and Energy Consumption
- Increased Capacity: 50% higher production capacity than hot-feed extruders with larger extrusion volume
- Low Overall Energy Consumption: Despite higher single unit power consumption (2-4 times comparable hot-feed), elimination of hot refining reduces overall energy consumption by over 35%
Superior Product Quality
- High Density: Die head pressure 2-4 times higher than hot feed extrusion, resulting in stronger pressure stability and more uniform, dense extrudate
- Dimensional Stability: Improved product quality, enhanced surface finish, and consistent dimensional specifications
- Less Prone to Scorching: Short rubber compound thermal history and low discharge temperature reduce premature vulcanization likelihood
