Rotor-stator homogenizers (also called colloid mills or Willems homogenizers) generally outperform cutting blade-type blenders and are well suited for plant and animal tissue. Combined with glass beads, the rotor-stator homogenizer has been successfully used to disrupt microorganisms.

1. Introduction. The term rotor impact mills refers to crushing machines, in which the crushing is carried out by impact stresses, and the kinetic energy (impact energy) required to produce the impact stress is applied by the rotary movement of rotors.. Rotor impact mills cover a wide fineness range, which extends from a final particle size in the area of a few millimetres, …

The rotor windings in the squirrel-cage rotor are short-circuited at both ends by means of the end-rings. In the slip-ring rotor the three-phase rotor windings are not short-circuited, but accessible through the slip-rings. External resistors can be connected to the rotor circuit, which improves the self-starting

3.2 Shaft speed. The 2nd key design and operational aspect for a hammer mill is the rotation speed. As the milling principle is based on the energy of the impact, the higher the speed, the finer the product can be expected as the particles will hit the hammer at high speed, but also be sent against each other or against the screen at high speed.

The Rotor design is the key to the operation of the open-ended spinners. Each type of fibre may require a different rotor design for optimum product quality and processing speed. The first open-end machines in the United Kingdom were placed, under great secrecy, by courtaulds into maple mill, Oldham in 1967.
