Product Description

A Davis Tube is a laboratory instrument designed to separate small samples of strongly magnetic ores into strongly magnetic and weakly magnetic fractions. It has become a standard laboratory equipment used for the assessment of the separability of magnetic ores by low-intensity magnetic separators. It was developed in 1921 and  no significant changes have been made in its design since then. The separator consists of an inclined tube 25 mm in diameter, placed between pole-tips of an electromagnet. Material to lie separated is passed through the tube; the strongly magnetic fraction is held by the magnetic field while the weakly magnetic material is washed down the tube.
It was suggested that a magnetic induction of 0.1 T or greater between the magnet poles should be used. However, others claimed that the current practice was to conduct the Davis Tube tests at a magnetic induction equal to that on the surface of the drum of the magnetic separator. Since it is the magnetic force or the force index, and not the magnetic field strength, that are decisive in the operation, it is unlikely that this practice would yield correct information.
Computer modelling of the pattern of the magnetic force generated by drum magnetic separators and a Davis Tube Tester was carried out. It was found that in the case of conventional ferrite drum separators, with a standard gap of 25 mm between the drum and the tank. Davis Tube tests should be conducted at the magnetic induction of 0.1 T. On the other hand, correct assessment, of performance of a rare-earth drum can be obtained by operating a Davis Tube at about 0.3 T or higher, depending on the design of the magnetic systems of the drum.
A more powerful 4500 Gauss model is available.
The standard David Tube magnetic field can be adjusted from 0-3500 Gauss.





The Davis tube or Davis tube tester is a laboratory machine designed to separate a small sample of pulverized magnetic iron ore into magnetic and non-magnetic fractions. The Davis separation tube is positioned between poles of a powerful electromagnet at an angle of 45° (adjustable) that is agitated back and forth and rotated by a motorized system. Magnetic particles are collected inside the tube in the zone of intense magnetism and all non-magnetic minerals are washed out.
