ALLJIG® - JIGGING MACHINES<br />
IN DEMAND WORLDWIDE:<br />
NEW INSTALLATIONS IN NORTHERN AND EASTERN EUROPE!<br />
Europe´s largest stainless steel plant in Tornio, Finl<strong>and</strong> – producing 1.7 million tons a year – recently opened<br />
a <strong>new</strong> slag processing plant in September 2010. The main components of this <strong>new</strong> plant are two powerful<br />
alljig®-jigging machines, ordered by TAPOJÄRVI, which runs the plant on behalf of OUTOKUMPU. The slag,<br />
a by-product of steel production, still contains 5 - 10 % metal, <strong>and</strong> the alljig®-jigging machines separate out<br />
this valuable metal <strong>for</strong> metallurgical reprocessing. The other product is metal-free slag that can be used as<br />
aggregate. As raw materials are becoming increasingly scarce, there is a growing trend toward economical<br />
processing of by-product slag from ferrochromium, ferromanganase <strong>and</strong> stainless steel production. In turn,<br />
there has been a noticeable spike in dem<strong>and</strong> <strong>for</strong> alljig®-jigging machines, particularly in Northern <strong>and</strong> Eastern<br />
Europe. Within the last five years, allmineral has increased its market share there considerably – <strong>and</strong> it looks<br />
like things will only get better.<br />
alljig®-jigging machines<br />
On September 8, 2010 the residents of the town of Tornio<br />
on the Finnish-Swedish border were treated to a special visit<br />
from Mauri Pekkarinen, the Finnish Minister of Economic<br />
Affairs, <strong>and</strong> the Senior Vice President of OUTOKUMPU.<br />
Both attended the official opening ceremony <strong>for</strong> the stateof-the-art<br />
processing plant at the largest stainless steel<br />
plant in Europe – which is also the biggest employer in the<br />
region.<br />
TAPOJÄRVI will run the <strong>new</strong> plant that makes it possible<br />
to extract the last bit of valuable metal from stainless<br />
steel slag. Air-pulsed alljig®-jigging machines are the<br />
core equipment of this process, <strong>and</strong> take advantage of<br />
gravity by using the difference in metal <strong>and</strong> slag density<br />
to efficiently separate the two. These machines from<br />
Germany are designed <strong>for</strong> capacities of 50-100 tons per<br />
hour, while efficiently sorting particles ranging in size from<br />
one millimeter to 32 millimeters.<br />
