Low-intensity separators are used to treat ferromagnetic materials and some highly paramagnetic minerals. Minerals with ferromagnetic properties have high susceptibility at low applied field strengths and can therefore be concentrated in low intensity (<~0.3T) magnetic separators. For low-intensity drum separators used in the iron ore industry, …

Maximum shear stress theory states that yielding will occur when a particular point undergoes a maximum shear stress that is equal to half of the uniaxial yield strength. A uniaxial ("one-axis") stress is a force acting in one direction, along its primary axis.
Longitudinal and transverse stresses have been measured in copper, iron, and mild steel, using manganin stress gauges. The results have been used to calculate shear stress from the difference between the stress components. Results indicate that copper displays an increase in shear stress with pressure, showing similar trends to …

The stresses obtained for all but the lowest magnetic inductions are controlled by the saturation of the magnetization in the contact regions of each particle. Identifying the maximum shear stress as a function of shear strain with the yield stress gives values in agreement with results reported for typical fluids.
The stress left in the material is known as residual stress. When an electrical steel sheet affected by residual stress is magnetized, the stress prevents the magnetic domains from being aligned in the direction of the external magnetic field [5]. The extent of this effect is determined by the magnitude of the residual stress [6], [7].
