Force in Blender

Dear sir,
During mixing in blender which force will work?
e.g. Mechanical force, Centrifugal force etc. Which one? @sunilrbudhkar

Blending and Mixing is the reorientation of particles relative to one another in order to achieve uniformity.

Following are the operating principles of different types of blenders,

a. Diffusion Blending (Tumble)
Particles are reoriented in relation to one another when they are placed in random motion and inter particular friction is reduced as the result of bed expansion (usually within a rotating container);
also known as tumble blending.

b. Convection Mixing
Particles are reoriented in relation to one another as a result of mechanical movement; also known as a paddle or plow mixing.

c. Pneumatic Mixing
Particles are reoriented in relation to one another as a result of the expansion of a powder bed by gas.

Examples of each type of blenders are given below,

a Diffusion Mixers (Tumble)

Diffusion mixer subclasses primarily are distinguished by the geometric shape and the positioning of the axis of rotation.

  • V-blenders
  • Double Cone Blenders
  • Slant Cone Blenders
  • Cube Blenders
  • Bin Blenders
  • Horizontal/Vertical/Drum Blenders
  • Static Continuous Blenders
  • Dynamic Continuous Blenders

b Convection Mixers

Convection blender subclasses primarily are distinguished by vessel shape and impeller geometry:

  • Ribbon Blenders
  • Orbiting Screw Blenders
  • Planetary Blenders
  • Forberg Blenders
  • Horizontal Double Arm Blenders
  • Horizontal High-Intensity Mixers
  • Vertical High-Intensity Mixers
  • Diffusion Mixers (Tumble) with Intensifier/Agitator

c Pneumatic Mixers
Although pneumatic mixers may differ from one another in the vessel geometry, air nozzle type, and air nozzle configuration, no pneumatic mixer subclasses have been identified.
