World’s largest circular vibratory screener

Kason introduce 7 square metre vibratory screener capable of outputs up to 150 tonnes/h

WITH a diameter of 254cm, Kason’s model K100-2(IRC)-SS is the largest circular vibratory screener in the world, according to company president Henry Alamzad. With a screening area in excess of seven square metres, it can separate oversize particles from bulk material at rates up to 150 tonnes/h.

Totally enclosed for dust-tight operation, the unit features a high-capacity Kascade internal recycle screening deck design with two screens of the same mesh operating in series, allowing large-scale throughput without sacrificing efficiency or increasing its footprint.

Positioned directly above the conventional screening deck, the Kascade deck is of slightly smaller diameter, allowing for a 360° annular gap at the screen’s periphery. As this deck is fed with material at high rates, the on-size material falls straight through the screen of the Kascade deck and is funnelled through a hole in the centre of the lower conventional screen to the machine’s discharge outlet.

The overflow material (both on-size and oversize) then cascades over the screen’s periphery and on to the conventional screen deck that scalps the balance of the material in the normal fashion.

Other features include an air-lift system that allows rapid access to the interior of the unit for inspection, cleaning or screen changes, as well as an automatic lubrication system that pressure-feeds lubricant to the gyratory motor bearings, extending bearing life by flushing out any dead spots where lubricant might pool, and allowing 6–12 months between reservoir replacements.

Offered in gravity-fed and in-line pneumatic versions for batch or continuous operation, the separator is suitable for the scalping of bulk products such as foundry or ‘frac’ sand.

Kason manufacture a broad range of circular vibratory screeners as well as centrifugal screeners and circular fluid-bed dryers, coolers and moisturizers.
