The design of the Silverson Batch mixer not only substantially reduces mixing times, but also allows the machine the ability to operate far beyond the capabilities of a conventional agitator. Here’s how it works: The high-speed rotation of the rotor exerts a powerful suction, drawing liquid and solid materials upwards into the workhead. Centrifugal force then drives the materials towards the periphery of the workhead where they are rapidly milled between the rotor blades and the stator. This is followed by intense hydraulic shear as the materials are forced out through the perforations and back into the mix. Fresh material is continually drawn into the workhead, resulting in a circulatory pattern of mixing all below the surface. As a result, there is little or no turbulence above the surface and aeration is reduced to a minimum.
