Dry Drum Magnetic separator is one of the most widely used and versatile machines in mineral processing. Mineral technologies electrostatic separators suitable for manganese ore, magnetite, pyrrhotite, roasting ore, ilmenite, hematite, and other materials below 50mm granularity, dry magnetic separator, and wet drum magnetic separator. Application.
A magnet can exert a force on another magnet even from a distance without touching the other magnet, so the magnetic force exerted by one magnet on the other magnet is an example of non contact force. (1) Many toys work due to the magnetic force exerted by magnets fixed inside them. (2) The magnetic strips held to keep the …
IVAN ALEXIS HUAMAN SEGURA. Knowledge of magnetic and electrostatic forces dates back at least to the Greek philosopher Thales of Miletus, who lived about 600 B.C. Thales knew some of the magnetic properties of the mineral lodestone, and he was also aware that when amber was rubbed with animal fur, the electrostatic charge produced on the …
Electrostatic headphones and speakers operate on a completely different and more advanced principle than conventional "dynamic" or "moving coil" headphones and speakers. Conventional speakers and headphones stick a coil of wire inside a magnet, and glue this coil to a stiff cone or dome that's held in place with a springy suspension.

High Intensity Magnetic Separators are designed for either wet or dry applications. Dry separators typically consist of a magnetized rotor in which the magnetic force is opposed by centrifugal and …
Magnetic minerals were picked up and transported by the revolving disc and deposited as a magnetic fraction, whereas non magnetic materials followed the path of the feed and were discharged by gravitational force. 2.3. Electrostatic separation Electrostatic separation was carried out utilising a high-tension roll separator (Kelly and Spottiswood,
Magnetic force is an attraction, or repulsion that arises between opposite magnetic poles. The motion of charges causes magnetic force, which is a result of electromagnetic force. A charged body exerts electrostatic force, while a magnet exerts magnetic force. Magnetic forces do not cause this phenomenon as there is no magnetic effect observed.
Magnetic soft materials incorporate different kinds of magnetic fillers with soft material matrices to form functional composites.
