Figura 3: Centrifuga Knelson Figura 4: Separación en la centrifuga Falcon. 3. Centrífugas de lecho fluidizado pulsante (Jig Kelsey, concentrador MGS) Los equipos de este grupo, además de utilizar el movimiento de rotación y agua de fluidización, utilizan un movimiento de pulsación similar al que se observan en los jigs y mesas vibradoras convencionales.

The Kelsey Jig was going after particles around 10 microns. Some of the jigs operate at 100 times gravity. "We were pulsing at 2000 times per minute," Kelsey said. "A normal gravity jig operates at about 200 to 250 pulses per minute and may get up to 450.". While the concept of the Kelsey Jig had been formed to deal with a problem at ...

The elementary jig (Fig. 13.29) is an open tank filled with water. A thick bed of coarse heavy particles (ragging) is placed on a perforated horizontal jig screen. The feed material is poured from the top. Water is pulsated up and down (the jigging action) by pneumatic or mechanical plunger. The feed moves across the jig bed.

The Kelsey jig is offered in two models: the J1300 and J1800, the latter having greater capacity. Operating variables include: Hutch water flow Spin rate Pulsation frequency Pulsation stroke length Ragging SG, size and shape Bed depth Concentrate orifice diameter Internal screen aperture size Feed rate and density ( typically 20 to 25 tph at 40 ...
