Investigating mixing in a multi-dimensional rotary mixer ...

12/07/2010  One of the most common batch type rotary mixers in industrial use is double cone blender, where granular materials are caused to flow by a combination of the action of gravity and the rotating motion of the mixer. The double cone blender consists of a vertical cylindrical shell with the conical top and bottom. Despite the common usage of the double cone in batch

In most of the rotary mixers, the radial convection is faster than axial dispersion transport. This slow dispersive process hinders mixing performance in many blending, drying and coating applications. A double cone mixer is designed and fabricated which rotates around two axes, causing axial mixing competitive to its radial counterpart. Discrete Element Method (DEM)

Such a unit can also be categorized as a particle mixer [3]. In a rotary kiln, mixing is vital since it impacts the heat transfer performance from the freebody to the particle bed as well as the heat transfer in the bed itself. Knowledge of the particle dynamics and heat transfer is important to optimize the kiln operation in order to have higher process efficiency. Rotary cylinders

What is A Counter-current Rotating Pan Mixer

This flexibility allows the mixer to input mixing intensity over a wide range, hence the ability to homogenize a batch in fractions of the time required by other mixer types. A . Counter-current Rotating Pan Mixer. can be configured to input as little as 5 HP per 1000 pounds of mix at the low end, and as much as over 200 HP per 1000 pounds at the higher end depending on process

Both a rotary beater and an electric mixer are used for mixing ingredients. Although both types of mixers have 2 beaters, they work a bit differently. A rotary beater is a simple gear-driven machine that is turned with a hand crank. The hand crank spins the beaters. The speed of the beaters is determined by the speed of manual turning.

Mixing speed played only a minor role in the process, which depended chiefly on the amount of fluid added. In a second investigation, a factorial design approach was used to discriminate between alternative high-shear mixer designs and two comparable pregelatinized starches by using high mixing speeds as a process variable.
