Internal Mixer Overview
An internal mixer is essential rubber processing equipment used for mixing, plasticizing, and homogenizing rubber materials to prepare them for subsequent molding operations. This equipment ensures different rubber types and properties are combined to achieve desired physical and chemical characteristics.
Internal Mixer Structure and Operation
Key Components
Internal mixers consist of several critical components including motor, reducer, gearbox, and mixing drums. The drums serve as the primary mixing element, typically constructed from cast iron or steel and lined with protective rubber coatings.
Operating Principle
When activated, the motor transmits power through the reducer and gearbox to rotate the drums. This rotation creates a high-speed flow field inside the mixing chamber, subjecting the rubber compounds to intensive shearing and compression forces that thoroughly blend different rubber types and properties.
Production Process
Raw Material Preparation
Production begins with precise preparation of raw materials including rubber compounds, fillers, plasticizers, and vulcanizing agents. These materials are carefully weighed and pre-mixed according to specific formulation ratios to ensure consistent processing.
Mixing Procedure
Prepared raw materials are introduced into the internal mixer in predetermined ratios. Drum rotation generates high-speed internal flow fields that rapidly circulate the mixture while applying shearing and extrusion forces, creating a homogeneous rubber compound.
Temperature Control
Optimal drum temperature control around 100°C is critical for proper plasticization and homogenization of rubber materials, ensuring consistent product quality throughout the mixing process.
Vulcanization Treatment
Mixed compounds undergo vulcanization in specialized chambers where high temperature and pressure conditions promote cross-linking between rubber molecules, significantly enhancing the material's physical and chemical properties.
Final Processing
Vulcanized rubber blocks are precisely cut into specified sizes and shapes, then formed using calendering or extrusion equipment to create finished products meeting exact dimensional requirements.
Manufacturing Process Control
Mixing Ratio Determination
Precise mixing ratio determination based on product specifications represents the most critical aspect of internal mixer manufacturing, directly influencing the final product's physical and chemical characteristics.
Temperature Management
Maintaining drum temperature at approximately 100°C is essential for quality assurance. Temperature deviations above or below this optimal range can adversely affect product integrity and performance properties.
