Rotor Stators are high shear mixers that incorporate both a rotor and a stationary stator. As the rotor (or rotors) turns at high speeds within the stationary stator, it creates a vortex circulating the product through the gap between the rotor and stator, mechanically shearing the contents at high speeds and creating a very homogenous blend.
Bone Paste and Grinding Machine CM 180. Paste Grinding Machine Working Principle. Fluid or semi-fluid materials go through a high speed relative motion of a rotor and stator, so that the material can get the strong shearing force, frictional force, and the high frequency vibration, effectively being crushed, emulsified, and homogenized to get the fine …

The stator is the static part of the motor. The main function of the stator is to generate the rotating magnetic field. The stator frame, stator core and stator winding are the three parts of the stator. The stator core support and protect the three-phase winding of the stator. High-grade silicon steel stamping makes the core of the stator.
The SAG Mill is a machine added by Ender IO. It uses Micro Infinity (µI) to grind (or mill) items into their crushed variants, like Ores into Dusts. The SAG Mill has four output slots; recipes can have 1-4 different outputs, with different chances of obtaining those outputs. Uniquely, the SAG Mill can use Grinding Balls made from various materials to increase energy efficiency …

Advantages of the wound rotor/SER drive are: 1. If the SER converter drive fails, the drive can be switched to fixed speed bypass - starting the usual way with the LRS. 2. The converter only needs to be sized for 15-20% of the total motor rating with associated reduction in floor space, air-conditioning etc. The converter is only sized for the ...
