A twin-shaft forced mixing concrete mixer is a sophisticated piece of equipment designed for high-efficiency concrete production. Its main components work in harmony to ensure precise material handling, thorough mixing, and controlled discharge. The system integrates mechanical and electrical subsystems, including feeding, mixing, water supply, discharging, lubrication, and automation controls. Each component plays a critical role in achieving consistent mix quality, operational safety, and energy efficiency. Modern designs incorporate advanced features like automatic lubrication and precision sensors to optimize performance and reduce maintenance requirements.
Key Points Explained:
-
Feeding Device
- Hoisting Mechanism: Uses a brake motor and reducer to lift materials via wire ropes, ensuring controlled vertical movement.
- Feeding Track & Hopper: Guides the hopper's movement with limit switches for accurate positioning. The hopper's automatic discharge door opens at preset heights to release materials into the mixing tank.
- Safety Features: Limit switches prevent over-travel, while brake systems ensure stability during operation.
-
Mixing Device
- Twin-Shaft Design: Two parallel shafts with blades create intense shearing and folding actions for homogeneous mixing.
- Floating Oil Seals: Installed at shaft ends to prevent leakage and contamination, critical for maintaining mix integrity.
- Reducer System: Transmits power from motors to shafts at optimized speeds for efficient energy use.
-
Water Supply System
- Precision Metering: Delivers water in exact quantities via flow meters or weigh batchers, often integrated with the control system.
- Spray Nozzles: Ensure even distribution throughout the mix, avoiding localized saturation.
-
Discharging Mechanism
- Automated Gates: Electrically or hydraulically operated doors release mixed concrete at programmed intervals.
- Discharge Chutes: Direct flow to transport equipment without segregation or spillage.
-
Lubrication System
- Electric Oil Pump: Provides continuous lubrication to bearings and gears, reducing wear.
- Centralized Distribution: Channels oil to critical points like shaft seals and reducer assemblies.
-
Electrical Control System
- Programmable Logic: Coordinates component timing (e.g., feeding cycles, mixing duration) via touchscreen interfaces.
- Sensor Integration: Monitors parameters like temperature, viscosity, and motor load for real-time adjustments.
- Safety Interlocks: Prevents operation during maintenance or when safety guards are open.
-
Structural Frame
- Heavy-duty steel construction supports dynamic loads during mixing while dampening vibrations.
- Access platforms and guardrails facilitate maintenance without compromising safety.
