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?
