Multi Shaft Mixers
Multi Shaft Mixer is a processing unit for the production of viscous paste and emulsions in the cosmetic, pharmaceutical, food and chemical industries. It’s especially suitable to make paint, coatings and inks.
Construction Materials
Multi-shaft mixer is generally made of mixer tank, heating and cooling system, temperature control system, electrical control panel etc. The mixing tank combines in a single vessel one low-speed anchor agitator and one or two high-speed dispersers. Normally, this agitator is top installed at the center of the vessel for slow-speed mixing and the high-speed dispersers are installed in the room between the shaft and outside wings of the anchor mixer.
Working Principles
During the mixing operation, the anchor agitator rotates clockwise slowly. With the attached Teflon blades, the materials are scraped off the vessel wall and move upwards so they won’t always stick to the wall and burn.
The disperser is driven by ABB or Siemens motor and rotates at the speed of 1400rpm producing strong high shear force. The disperser mixer is even capable of shearing rubber chips, etc rapidly to shorten the dissolving time significantly.
Disperser is also replaceable with batch homogenizer for dissolving, homogenizing, and emulsifying.
Due to the two opposite forces by anchor agitator and disperser, the paste rolls over the vessel from top to bottom and back to top repeatedly. When the paste is completely mixed, the heat from the jacket is quickly transferred to every part through the inside wall.
