Pin Mills, type PST are used for fine to finest grinding of dry, brittle, or hard to grind materials to a fineness of d50=5 micron. Material is fed centrically by a dosing mechanism and magnetic separator. Grinding is done by impact and whirling between the concentrically mounted pin rows of the rotating and the stationary discs.

The wet milling machine benefits make them attractive investments. IKA wet milling machines are based on the rotor-stator principle. Exhibiting a high level of shearing energy input, milling machines can achieve particle sizes of 10 µm and below. IKA wet mill machines are capable of processing products with a broad spectrum of viscosity.

The rotor then is forced to rotate 60 degrees to line up with the stator poles as shown. At time 3, B-1 and A-2 are N. At time 4, A-2 and C-1 are N. As each change is made, the opposite poles on the stator attract the poles of the rotor. Thus, as the magnetic field of the stator rotates, the rotor is …

The friction and shear that result is commonly referred to as wet milling. The rotor and stator are cone shaped, and have three stages of increasingly fine serrations, or grooves. The stator can be infinitely adjusted to obtain the desired gap setting between the rotor and stator. The grooves change directions in each stage for increased ...

Specially designed rotor/stator mixers achieve ultra-high shear conditions which often result in extremely fine dispersions of pigments and other raw materials. More than just an ordinary 'pre-mixer', an ultra-high shear rotor/stator device can produce results comparable to one or two passes through a media mill.

The ShearPro™ rotor stator is a high intensity in-line mixer that can be used for blending, producing extremely stable emulsions, ultra-fine dispersions, accelerated reactions, and can eliminate fish-eyes and hydrate polymers and gums for thickening products. The ShearPro™ unit can be used in either once-through, or recirculating mixing processes.

It is installed to give a dis- tance of 6-8 mm between rotor and stator thereby forming a narrow annular grinding gap in the radial direction. To reduce contamination from wear, the rotor and the stator are coated with polyurethane. The material worn from the lining is, during sintering, burned out of the pow- Fig. 2.

The stator can be infinitely adjusted to obtain the desired gap setting between the rotor and stator. The grooves change directions in each stage for increased turbulence.

rotor/stator generator correlates with complete tank turnovers – and a homogeneous end product. The rotor/stator generator of the batch High Shear Mixer is generally positioned 2-3 head diameters from the bottom of the vessel, and slightly off-center. To ensure adequate suspension of heavier solids, the rotor/stator generator may be located in

Rotor and Beater Mills are ideal for pre-crushing and fine comminution of soft to medium-hard, brittle, fibrous and temperature-sensitive materials in analytic laboratories or industry. The sample is comminuted at high speed by impact and shearing forces.

A cone shaped rotor andstator has three stages with increasing teeth fineness for pre-milling, milling and fine milling. The gap between the rotor and stator is adjustable for adjusting the amount of milling required. MKO – Cone Mill A cone shaped rotor and stator has anabrasive coating that acts like a stone mill for ultra fine milling. The ...

This mill is supremely versatile, satisfying the most demanding quality requirements efficiently and cost­effectively. The product is fed to the milling chamber by an external variable­flow pump. The milling action is created in the gap between the conical working vessel – the stator – and a conical rotor. The gap is in the range 6.5 to

With the rotor and the stator there is a thin uniform film of material between them and it is subjected to the maximum amount of shear. Rough surfaced mill add intense eddy current, turbulence and the impaction of the particles to the shearing action. Principle of Colloidal Mill Colloidal mill works on the principle of rotor-stator.

Rotor/Stator Mixers are generally applied on products that are up to approx. 10,000 cps. The four-blade rotor of the standard design turns within a close tolerance stator at roughly 4,000 fpm. The higher energy units can rotate at speeds over 16,000 fpm and offer end results that are sometimes equal to or better than a conventional homogenizer.

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, down to less than ...

By installing a second drive on the door of the housing of the impact mill, the stator disc of the single-disc pin mill also becomes a rotor disc. Due to the counter rotation of these two pin discs the relative peripheral speed is increased up to 250 m s-1. This machine type can be used for similar applications as the conventional single pin ...
