A review on the advanced design techniques and methods of vibrating
Flip-flow vibrating screens (FFVSs) are the critical screening equipment for classifying and dewatering wet materials in mining processing industry. During the screening process, the FFVSs can be regarded as a complex rigid-flexible coupled multi-body system where the screening operation and the dynamics of two screen frames interact.

Wet Magnetic Drum Separator
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, the …

Why do we tap on cardboard to see magnetic field lines?
$begingroup$ @CarlWitthoft not a great analogy, because nodes on a vibrating plate are present only while the plate is actually vibrating, while e.g. a magnet exerts force on tiny pieces of metal continuously. Why is then additional vibration needed for the pieces to move and align along the field lines? This is answered by Ben51. …
Electromagnetic Waves ( Read ) | Physics | CK-12 Foundation
The electric and magnetic fields of an electromagnetic wave are areas of electric or magnetic force. The fields can exert force over objects at a distance. An electromagnetic wave begins when an electrically charged particle vibrates. This causes a vibrating electric field, which in turn creates a vibrating magnetic field. The two …
Magnetic Separators & Metal Detection for Aggregate Conveyors …
Metal detectors are capable of detecting all sources of tramp metal contamination. Meanwhile, magnetic separators are designed to attract and remove exclusively ferrous tramp metal. This is not a weakness, but a unique strength. Magnetic separators and metal detectors are frequently used together to achieve optimum removal of tramp metal.
Detecting and Removing Tramp Metal from Conveyors | Agg-Net
In a quarry or mine, metal detectors are commonly located underneath or around a conveyor belt. When tramp metal enters the magnetic field of the detector, the control panel either stops the conveyor or can divert the contaminated product flow. Master Magnets manufacture three designs of metal detector for the quarrying and mining industry.

Physical Property Measurement System
The torque magnetometer measures a sample's magnetic moment through the application of a static magnetic field to generate a torque on a small cantilever. The torsion is measured using piezoresistive elements to study the moment as a function of magnetic field strength, temperature, or angular orientation with respect to the field.
