What makes a mixer high shear?
A high-shear mixer uses a rotating impeller or high-speed rotor, or a series of such impellers or inline rotors, usually powered by an electric motor, to “work” the fluid, creating flow and shear.
Which mixture is a first high shear powder mixer?
Option (b) is correct. Littleford lodige mixer is also known as a granulator.
What is pharmaceutical shear?
Sufficient shear is required to mill and de-lump materials, achieve sufficient flow, and homogenize cohesive ingredients. Shear mixing plays a critical role in the blending of dry powders, particularly for those that contain a minor cohesive component such as a solid lubricant or a drug.
What is high shear granulation?
High shear granulation is a shaping process for granulation that has been enhanced for application in the pharmaceutical industry. A binder liquid is fed to the powder particles in a closed container with blending tools and a chopper. Dense granules are formed through the liquid and solid bridges that result.
What is Silverson mixer homogenizer?
Silverson Mixer Homogenizers are fast and efficient and are capable of producing a fine droplet or particle size, typically in the range of 2 – 5 microns. This degree of homogenization is suitable for the vast majority of products, such as creams and ointments, lotions, sauces and flavor emulsions.
What is the working principle of Silverson mixer?
The high-speed rotation of the rotor blades within the precision machined mixing workhead exerts a powerful suction, drawing liquid and solid materials upwards from the bottom of the vessel and into the center of the workhead.
What is a high speed mixer?
High speed mixer (also called agitator or disperser) is an equipment for mixing liquid and solids to dissolve, disperse and homogenize . With high speed, the media is stirred, dissolved and distributed evenly. The hydraulic pump drives the hydraulic cylinder ascend and descend, which drives the whole transmission and working set up and down.
What is industrial mixer?
Industrial Mixers. Industrial mixers are used for mixing large quantities of material, or materials with higher viscosities and torque requirements. With the right mixer and propeller, industrial mixers can mix up to 1500 gallons (5700 liters) of material with a viscosity of 1000 cps.
What is shear mixing?
Shear mixing is caused by a velocity gradient within the material. Because powder flows are poorly understood at the present time, the effect of variables such as blender size, fill level, or speed of rotation of the blender have on shear rate can be established only qualitatively at best.
What is inline mixer?
What is “In Line Mixer”? An audio mixer configured to be able to monitor multitrack tape returns through the same channels that are used for inputs from microphones, line input sources, etc (see WFTD In Line Monitoring ). This is in contrast to a configuration known as a split mixer, which has separate inputs dedicated to tape sends and returns.
