Multishaft Mixers/Dispersers

These machines will increase productivity and versatility of high viscosity batch processing. They are suitable for mixing and dispersing materials with high viscosity in excess of 100,000 cps that tend to stick to the wall of the mixing vessel. The high speed blade will disperse the materials at a tip speed of 5200 feet per minute, while the large open type impeller, rotating in the range of 300 to 1300 feet per minute, will keep the high viscous materials flowing. This system produces swift dispersions in applications from paste inks to coatings, plastisols, adhesives, caulking compounds, and specialty chemicals.

The disperser and the mixer may be running one at time or both at the same time. Typical speed ranges at the mixing shaft are 600 to 1400 rpm for the high speed disperser and 30 to 90 rpm for the low speed mixer from 1 to 5 HP laboratory/pilot line models and from 5 to 100 HP production models.

These units are offered in laboratory models and production models in tank mounted version (Series 4020) and post mounted version (Series 4022) in fixed or variable speeds, with mechanical drives or variable frequency drives. Models range from laboratory sizes to pilot line sizes to production sizes with tank capacity exceeding 3000 gallons.

These machines may also be designed with a variable speed belt/motor/drive system using very high efficiency AC motors coupled to a Variable Frequency Inverter for a soft start of the machine, for precise speed control and for significant energy saving. Tank mounted units are Model DVF from Series 4070, while the post mounted units are Models HVF form Series 4072.

The Dual Shaft Mixer/Dispersers may be supplied with several features which will add to versatility and economy. Features such as vacuum/pressure operation, choice of interchangeable mixing vessels, choice of fixed and portable vessels with heating/cooling jackets or external pipe coils for hot oil heating, choice of drives, choice of low speed anchor or helical turbines. A stator/rotor dispersing head may be added for superior high shear results. Wetted stainless parts may be polished to more than 240 grits.
