'''Mixers ''' are used to mix or blend a wide range of materials used in different industries including the food, chemical, pharmaceutical, plastic and mineral industries. They are mainly used to mix different materials using different types of blades to make a good quality homogeneous mixture. Included are dry blending devices, paste mixing designs for high viscosity products and high shear models for emulsification, particle size reduction and homogenization.  Mixers range from laboratory to production line scale, including [[Ribbon Blenders]], [[V Blenders]], [[Cone Screw Blenders]], [[Screw blenders]], [[Double Cone Blenders]], Double Planetary [[High Viscosity Mixers]], Counter-rotating, Double & Triple Shaft, [[Vacuum Mixers]], [[Planetary Dispersers]], High Shear Rotor Stator and [[Dispersion Mixers]], [[Paddle Mixers]], [[Jet Mixers]], [[Mobile Mixers]] and [[Drum Blenders]]. The [[Banbury mixers]] are effective at mixing or kneading viscous materials.  They can operate at different temperatures and pressures for mixing different solutions and can also have internal or external heating systems added to them.

Systems can come equipped with hydraulic or electronic soft start mechanisms so that they start and stop smoothly.

== Basic Nomenclature == 
For liquid mixing, the nomenclature is rather standardized: 
* Impeller Diameter, "D" is measured for industrial mixers as the maximum diameter swept around the axis of rotation.
* Rotational Speed, "N" is usually measured in revolutions per minute(RPM) or revolutions per second(RPS).  This variable refers to the rotational speed of the impeller as this number can differ along several points of the drive train.
* Tank Diameter, "T" The inside diameter of a cylindrical vessel.  Most mixing vessels receiving industrial mixers will be cylindrical.
* Power, "P" Is the energy input into a system usually by an electric motor or a pneumatic motor
* Impeller Pumping Capacity, "Q"  The resulting fluid motion from impeller rotation. 


 
==Options==  
==Mixing Calculations==  
* Spray nozzles
The level of mixing is determined by the pumping effect or dynamic response that the mixer imparts into the fluid.  When a mixing impeller rotates in the fluid, it generates a combination of flow and shear.  The impeller generated flow can be calculated by using the following equation: 
* CIP
:''Flow (GPM) = (Flow_Number * RPM * Impeller_Diameter^3) / 231'' 
* PLC
To calculate power draw, use the following equation: 
* Pneumatic or electric systems
:''Power (HP) = (Power_Number * RPM^3 * Impeller_Diameter^5 * Fluid_Specific_Gravity) / (1.525 * 10^13)''
* Hydraulic or electronic soft start mechanisms so that they start and stop smoothly

Mixers are used to mix or blend a wide range of materials used in different industries including the food, chemical, pharmaceutical, plastic and mineral industries. They are mainly used to mix different materials using different types of blades to make a good quality homogeneous mixture. Included are dry blending devices, paste mixing designs for high viscosity products and high shear models for emulsification, particle size reduction and homogenization.

Mixers range from laboratory to production line scale, including:


Options

  • Spray nozzles
