Anchor Agitated Reactors

Anchor Agitated Reactors from Roben Manufacturing deliver superior mixing performance for high-viscosity materials requiring thorough agitation. These specialized reactors feature anchor-style impellers designed to scrape vessel walls and ensure complete material turnover in demanding mixing applications.

What Are Anchor Agitated Reactors?

Anchor Agitated Reactors are mixing vessels equipped with anchor-shaped impellers that rotate close to the vessel wall, providing effective agitation for viscous fluids that would otherwise create stagnant zones. The anchor design scrapes material from vessel surfaces while promoting bulk flow patterns essential for uniform mixing and heat transfer.

Why Choose Roben Anchor Agitated Reactors?

• Excellent wall-scraping action prevents material buildup and hot spots
• Effective mixing of high-viscosity fluids up to 100,000 cP and beyond
• Uniform heat transfer through continuous surface renewal
• Reduced processing times compared to conventional agitators
• Prevents product degradation from localized overheating

Key Features and Capabilities

• Close-clearance anchor design with adjustable wall gaps
• Heavy-duty drive systems for high-torque applications
• Optional heating/cooling jackets for temperature control
• Multiple anchor configurations including double and helical designs
• Sanitary and industrial finish options available

Applications

• Polymer melt processing and compounding
• Adhesive and sealant manufacturing
• Food processing with viscous ingredients
• Pharmaceutical cream and ointment production

Compliance and Certifications

Our Anchor Agitated Reactors meet rigorous industry standards including ASME Section VIII Division 1 for pressure vessel construction, ISO 9001:2015 quality management certification, and API standards for petroleum industry applications. Each reactor receives U-stamp certification with National Board registration and complete documentation supporting regulatory approval and customer specifications.

Quality Assurance

Every packed agitated reactor undergoes comprehensive quality verification: radiographic or ultrasonic examination of pressure welds as required, positive material identification (PMI) of critical components, hydrostatic testing per ASME requirements, agitator mechanical testing, and complete documentation with full material traceability. Our quality program ensures consistent excellence in every reactor we deliver.

Frequently Asked Questions

Q: What viscosity range is suitable for anchor agitated reactors?

A: Anchor agitators excel with viscosities from 5,000 cP to over 100,000 cP. For lower viscosities, turbine agitators may be more efficient. We help select the optimal agitator style based on your specific material properties and process requirements.

Q: How close should the anchor be to the vessel wall?

A: Typical clearances range from 1/8″ to 1/2″ depending on viscosity and application. Closer clearances improve scraping action but require tighter manufacturing tolerances and more precise installation. We optimize clearance for your specific process.

Q: Can anchor agitators handle materials that change viscosity during processing?

A: Yes, anchor agitators are ideal for processes where viscosity increases significantly, such as polymerization reactions. The high-torque drives accommodate viscosity changes, and the scraping action maintains heat transfer as materials thicken.
