Description
Available for sale is a used ROSS Model CDA-300 Dual Shaft Vacuum Mixer, engineered for demanding mixing, dispersing, homogenizing, and vacuum processing applications. This versatile system combines a high-speed disperser with a low-speed sweep agitator, providing excellent product turnover, efficient heat transfer, and superior mixing performance across a wide range of viscosities.
The mixer is supplied with a portable 300-gallon jacketed mixing vessel rated for full vacuum operation at 300°F and equipped with a heating/cooling jacket rated for 50 PSI at 300°F. The dual-shaft design allows simultaneous macro-mixing and high-shear dispersion, making it ideal for products requiring powder incorporation, pigment dispersion, emulsification, and vacuum deaeration.
Powered by explosion-proof motors, including a 30 HP high shear disperser drive and a 20 HP sweep agitator drive, this system is suitable for hazardous and solvent-based processing environments commonly found in chemical, coatings, adhesives, cosmetic, pharmaceutical, and specialty materials manufacturing facilities.

Frequently Asked Questions

What is the capacity of the ROSS CDA-300?
The mixer is equipped with a 300-gallon jacketed mixing vessel.

What type of mixing system does this unit use?
The system utilizes a dual-shaft design consisting of a high shear disperser and a sweep agitator.

What is the advantage of a dual-shaft mixer?
Dual-shaft mixers provide simultaneous high-shear dispersion and low-speed bulk movement for faster, more uniform mixing.

Is the vessel rated for vacuum operation?
Yes, the tank is rated for full vacuum service at temperatures up to 300°F.

What is the jacket pressure rating?
The vessel jacket is rated for 50 PSI at 300°F.

What motors are installed?
The system includes a 20 HP sweep agitator motor and a 30 HP high shear disperser motor.

Are the motors explosion proof?
Yes, both motors are explosion-proof (XP) rated.

What products are commonly processed in this type of mixer?
Adhesives, coatings, sealants, cosmetics, pharmaceuticals, inks, resins, and specialty chemicals are frequently processed in dual-shaft vacuum mixers.

Why is vacuum mixing beneficial?
Vacuum processing removes entrapped air, improves product consistency, enhances dispersion, and reduces foam formation.

What industries commonly use ROSS dual-shaft mixers?
Chemical, coatings, adhesives, pharmaceutical, cosmetic, personal care, and specialty materials manufacturers commonly utilize these systems.

Can Aaron Equipment assist with shipping and logistics?
Yes, Aaron Equipment can coordinate inspections, rigging, loading, transportation, export documentation, and worldwide logistics services.

Does Aaron Equipment buy and sell used ROSS mixers and process equipment?
Yes, Aaron Equipment actively purchases and sells used mixers, dispersers, reactors, tanks, blenders, process systems, and complete manufacturing facilities worldwide.
