XK-550 Type Rubber Mixing Mill With 100kg Per Batch Capacity
This industrial rubber mixing system combines a 110L Kneader with an XK-550 Open Mixing Mill for efficient two-stage processing, delivering superior mixing quality and production capacity of 100kg per batch.
Two-Stage Mixing Process Overview
This modern setup replaces labor-intensive single-stage mixing with an optimized two-phase approach:
- Stage 1: 110L Kneader (Intermixer) for intensive mixing, blending, and plastication
- Stage 2: XK-550 Open Mixing Mill for final mixing, homogenization, and sheet production
110L Rubber Kneader Specifications
This batch-type internal mixer serves as the primary workhorse for initial compound preparation:
- Function: High-intensity mixing of polymers, fillers, oils, and chemicals
- Capacity: 110L chamber (65-80kg actual batch weight)
- Advantages: Faster mixing, superior dispersion, enclosed design reduces dust/fumes
- Operation: Uses counter-rotating, intermeshing rotors in sealed chamber
XK-550 Open Mixing Mill Features
The finishing unit completes the mixing process and prepares material for downstream processing:
- Function: Final mixing, homogenization, cooling, and sheeting
- Capacity: 100kg per batch (550mm roll diameter × 1500mm length)
- Key Processes: Dumping, blending, sheeting, and cooling
- Operation: Uses counter-rotating rolls with differential speeds/temperatures
Standard Rubber Mixing Workflow
- Precise weighing of all raw materials
- Rubber loading and mastication in kneader
- Intensive mixing with additives in kneader
- Masterbatch transfer to XK-550 mill
- Final mixing and curative addition on mill
- Sheeting and cooling process
- Storage or feeding to downstream processes
System Advantages
- High productivity with optimized labor requirements
- Superior compound quality and consistency
- Precise control over mixing parameters
- Reduced manual labor compared to open mill-only systems
