Overview

The document details the specifications, features, and operational procedures of the GMⅡ-t Series Gran Mixer machines, designed for mixing virgin pellets and granulated recycled materials efficiently. These machines integrate measuring, mixing, and granulating functions with advanced control systems including touch panels and buzzer alerts.

1. Measurement and Control Procedures

• Virgin pellets (V) and granulated materials (R) are measured multiple times using a measuring cup to establish reference values.
• The system automatically calculates and stores the average measurement, which is then transferred for processing.
• Molding conditions are input to automatically set the screw rotation speed.
• The machine compensates for differences between actual measurements and provisional calculations to ensure accurate mixing ratios.

2. Key Features and Benefits

• Instant mixing of virgin and granulated materials with a stylish design.
• Touch panel and buzzer alerts notify operators of granulator stoppages or full bins.
• Easy material replacement and tool-free disassembly for cleaning.
• Mixture tanks store pre-mixed virgin and recycled materials without agitator blades, simplifying maintenance.
• Improved mixing screw design and automated screw stop during measurement enhance ease of use.
• Motor mounted on frame to simplify cleaning procedures.
