Product Specifications

Technical details and manufacturing context for Agitator System

Definition
The Agitator System is a component used in the non-metallic mineral product manufacturing industry, specifically for asphalt storage tanks. Its primary function is to continuously agitate the asphalt to prevent settling of aggregates, maintain uniform temperature distribution, and ensure consistent material properties throughout the storage period. By preventing asphalt from hardening or separating into layers, the system is essential for maintaining product quality and ensuring proper flow characteristics during discharge.

The system typically consists of motor-driven rotating shafts with mixing blades or paddles that create controlled turbulence within the tank. It may operate continuously or intermittently, depending on tank design and material requirements. Speed and torque are carefully controlled to achieve thorough mixing without damaging the asphalt structure or causing excessive heat generation.

Key parameters to consider when selecting an agitator system include rated power (5.5–22 kW), agitator speed (30–80 r/min), tank capacity (20–100 m³), impeller diameter (800–2000 mm), operating temperature (120–180 °C), operating pressure (0.1–0.3 MPa), motor protection class (IP55–IP65), shaft seal type (mechanical seal), material of wetted parts (316L), noise level (≤85 dB(A) at 1 m), and weight (800–2500 kg). These values are reference ranges and must be verified for the specific model and application.

Materials commonly used include carbon steel, stainless steel, and wear-resistant alloys. Relevant standards for verification include IEC 60034 for rated power, IEC 60529 for motor protection, API 682 for shaft seals, ASTM A240 for material, and ISO 3746 for noise level. These standards serve as procurement references; they do not imply certification or compliance of any specific product.

For proper selection, the buyer must confirm tank dimensions, asphalt viscosity, and operational requirements with the manufacturer or supplier. Maintenance signals include unusual noise, vibration, or reduced mixing efficiency. Failure boundaries include seal leakage, motor overload, or blade wear. Always verify model-specific values and standards with the legal manufacturer or supplier.
Working Principle
The agitator system uses a motor to drive a shaft with blades or paddles, creating turbulence in the asphalt. The speed and torque are controlled to achieve thorough mixing without damaging the asphalt. It can run continuously or intermittently, depending on the tank design and material needs. The system prevents settling and maintains uniform temperature, ensuring consistent viscosity.
