MR-160 (6-Inch) Laboratory Intelligent Safety Two-Roll Open Mixing Mill
Product Details
MILL MR-160 (6-Inch) Laboratory Intelligent Safety Two-Roll Open Mixing Mill is a premium, compact mixing system engineered for the highly precise blending, plasticizing, and dispersing of rubber, plastics, color masterbatches, and advanced polymer composites. Driven by advanced German engineering philosophies, it is uniquely optimized for research institutes, universities, and corporate R&D centers to analyze material property variations and evaluate batch dispersion quality with clinical precision.
1. Product Overview
The MILL MR-160 open mixing mill integrates industrial-grade durability into a laboratory-scale footprint. This system is heavily utilized for advanced formula screening and compounding analysis, delivering remarkable precision and operational excellence while strictly adhering to international health and safety protocols.
2. Engineering Highlights & Advanced Technology
Ultimate Operator Safety: Equipped with a humanized multi-directional braking system, including an ergonomic knee-touch emergency switch that triggers a full stop within 0.5 seconds. Features an aerodynamic curved safety hood and 360° dead-zone free emergency pull-rods to ensure absolute operator protection.
Precision Temperature Control: Utilizes an Electric Heating System with high-efficiency internal cartridge heaters combined with variable-density internal heating elements to effectively compensate for roller-edge heat dissipation, achieving perfect temperature uniformity across the working surface (static thermal accuracy up to ±2°C). Supports rapid, high-conduction water cooling.
Universal Joint Drive: Driven by high-torque universal joint shaft couplings instead of traditional ratio gearboxes. This sophisticated transmission delivers smooth, high-load power delivery, dramatically lowers operating noise (<62dB no-load), and completely eliminates the oil leakage and weeping issues common in older mills.
Siemens PLC Smart Control: Features a vibrant color touch-screen Human-Machine Interface (HMI) that records and graphs real-time dynamic processing data (time, temperature, current, and torque). Supports seamless data export to Excel via USB and comprehensive recipe management.
Digital Gap Adjustment: Equipped with an effortless manual roller-gap adjustment mechanism integrated with a high-precision electronic digital display accurate to 0.1mm, ensuring maximum formula reproducibility.

5. Site & Infrastructure Requirements
To ensure a seamless installation and commissioning phase, overseas clients are kindly requested to verify and prepare the following facility utilities prior to the equipment's arrival:
Power Supply: 380V, 50Hz/60Hz, 3-Phase 5-Wire system (Three live lines, one neutral line, and one ground line). Voltage stability must be maintained within ±10%. *Custom voltage configurations (e.g., 220V/415V/440V 3-Phase) are fully available upon request to match country-specific grids.
Water Supply: Main inlet water pressure should ideally range between 0.2 and 0.4 MPa. Industrial softened water or closed-loop chiller water is highly recommended to prevent internal limescale scaling over time, although standard clean tap or cooling tower water can be successfully utilized.
Unloading Equipment: Given that this is a rigid, heavy-duty industrial assembly weighing approximately 950 kg, a standard forklift (rated ≥ 1.5 Tons) or a workshop overhead crane must be arranged by the buyer at the discharging dock.
