Including wet high intensity, induced roll, rare earth roll, rare earth drum, low intensity and medium intensity magnetic separators the Reading range has a magnetic solution to fit your particular processing requirements.

The WHIMS range includes 4, 16, 24 and 48 pole machines with either 68 or 120 millimetre separation matrix widths. WHIMS separators are suitable for applications requiring higher magnetic field gradients to remove weakly magnetic particles from non-magnetic concentrates. Nominal capacities range from 6 to 150 tonnes per hour.

Reading induced roll and semi-lift induced roll magnetic separators are available with 2 starts, single or twin-pass configurations in 133 millimetre roll diameter and 760 millimetre roll width or 160 millimetre roll diameter and 1000 millimetre roll width, and deliver nominal capacities of up to 12 tonnes per hour. Pilot roll laboratory scale separators are available in both induced roll and semi-lift induced roll configurations.. Typical applications include:

The rare earth magnetic separator range achieves the most effective dry separation of paramagnetic minerals at high throughput rates. The range includes Rare Earth Roll (RERS) and Rare Earth Drum (REDS) Separators which are available in a range of configurations and sizes from lab units to full production units.

Separation of paramagnetic minerals by using a dry high-intensity magnetic separator.Granulometry of magnetic fraction changes based on process variables of IRMS.Rotor speed and splitter position majorly influence the magnetic fraction of IRMS.Influence of interactional effects of variables of IRMS analysed statistically.

Dry high-intensity magnetic separators are one of the most common magnetic separation methods extensively used for the concentration of paramagnetic minerals based on their magnetic susceptibility, particle size, particle density, and shape. In this paper, the influence of particle size on the separation of the garnet particle in Induced Roll Magnetic Separator (IRMS) was investigated by varying the magnetic field intensity, rotor speed, feed rate, and splitter position. The influence of particle size on a magnetic fraction of Induced Roll Magnetic Separator was analysed as the D50 (m) and D80 (m) size. The results show that segregation of the coarser particle is segregated in non-magnetic fraction while finer sized particles are at the magnetic fraction. To understand further, particle size distribution is analysed by Rosin-Rammler equation and the variation of the constants are explained by statistics. Also, the influence of individual variables and their interactions on the segregation pattern is described by analysis of variance method along with response surface plots.

Separation of garnet fines was studied by using dry high intensity induced roll magnetic separator. In this study, effect of the particle size on magnetic separation in IRMS was investigated based on different operating variables. A four-level Box-Behnken design combining with a response surface methodology (RSM) and quadratic programming (QP) were employed to understand the effect of variables on the particle size separation of paramagnetic minerals.

High intensity dry magnetic separators are gaining popularity for the separation of para-magnetic minerals due to the cost economic factor. Induced roll magnetic separator is found to be an effective dry separator for the separation of fine particles. Separation efficiency of this separator depends on mineral characteristics and the design features of equipment along with the optimization of process variables. Present investigation focuses on the prediction and validation of separation performance of minerals while treating in induced roll magnetic separator. Prediction of the separation is expressed in terms of separation angle at which a particle leaves the rotor surface by using a modified particle flow model derived by Cakir. The validation of the model is carried by capturing the particle trajectory using an image analyzer. It is found that Cakirs mathematical model produces reliable results and a new model is proposed to increase the reliability of separation angle prediction by including the particle shape factor.

dry magnetic separation of iron ore of the bakchar deposit - sciencedirect

Currently, the development of iron ore of the Bakchar deposit (Tomsk region) is considered promising because of the extremely large reserves of iron ore. Ores of this deposit are related to the high-grade type and expected to have a magnetic concentration for iron extraction. The main task of magnetic separation is to increase the total iron content in concentrates to a value which allows its further metallurgical processing. Ferruginous ore particles have a rounded shape that facilitates a separation process. The paper considers the influence of technological parameters on the magnetic concentrate yield and recovery rate of iron-containing fractions.
