Description

AN AGGREGATE SEPARATION APPARATUS
The present invention relates to an aggregate separation apparatus; in particular an improved aggregate separation apparatus for separating light fraction aggregate from that of the aggregate bulk.
Aggregate separation apparatus such as eddy current separators are used for sorting and separating metallic articles from a bulk of aggregate. By using devices such as eddy current separators, it is possible to recover metals, for example aluminium from domestic, commercial and industrial waste. Eddy current separators conventionally comprise a conveyor for transport of the bulk aggregate to a rotating drum containing magnets. The rotating drum rotates such that eddy currents are created. Eddy currents interact with different types of metallic aggregate. If the metallic aggregate is light and conductive the metallic aggregate will rise and is ejected from the normal flow of bulk aggregate into an associated collection chamber/container. The ejected metallic aggregate can be separated from that of the non-metallic aggregate which will be transported along the conveyor and then fall off the drum into an associated non-metallic aggregate collection chamber/container.
However, all non-metallic aggregate including light fraction aggregate will fall off the drum and into the non-metallic aggregate collection chamber/container. It will be appreciated that light fraction aggregate includes dirt, sand, paper and films etc. The non-metallic aggregate will then require re-separation to separate the light fraction aggregate from that of the rest. These conventional methods can be cumbersome and time-consuming tasks and can also be labour intensive; ultimately increasing costs.
It is an object of the present invention to provide an improved aggregate separation apparatus and to provide an aggregate separation apparatus that enables a more efficient separation of aggregates from the aggregate bulk.
Accordingly, the present invention provides an aggregate separation apparatus comprising: an aggregate guide means and an aggregate separating means; the aggregate guide means guiding the aggregate to the aggregate separating means, wherein the separating means comprises a magnetic separating means and an air separating means located proximal to each other.

The receiving portion (10) of the aggregate guide component (2) is located at an opposing end of the aggregate guide component (2) from that of the aggregate separating arrangement (3). The air separating mechanism (5) is located vertically directly above the magnetic separating mechanism (4).
The air separating mechanism (5) and the magnetic separating mechanism (4) are in operational engagement with one another. The location of the air separating mechanism (5) proximal to the magnetic separating mechanism (4) results in that light fraction aggregates (not shown) are removed just before magnetic separation. Therefore, the waste (not shown) is cleaned to avoid any potential decontamination of the separated material (not shown).
The magnetic separating mechanism (4) has a rotatable outer drum (not shown). The rotatable outer drum (not shown) is in operational engagement with the aggregate guide component (2).
