Abstract
The invention relates to a device for continuously sorting a particulate stream, comprising: a) a conveyor (1) for conveying the particulate stream to a separation device, b) a sieve (7) for separating the particulate stream according to size, characterized in that it further comprises c) a per-sieve (3) comprising elongated sieve openings located between the convey or outlet and the sieve d) and a mechanical impact device for providing mechanical impacts to the pre-sieve (3). The pre-sieve allows to separate elongated objects like threads or wires form the particulate stream which would otherwise clog or block subsequent separation devices including the sieve.
Claims17
Device for continuously sorting a particulate stream, comprising:
- a) a conveyor (1) for conveying the particulate stream to a separation device,
- b) a sieve (7) for separating the particulate stream according to size,
- characterized in that it further comprises
- c) a pre-sieve (3) comprising elongated sieve openings, formed by fingers extending towards an end portion of the pre-sieve with the tips of the fingers not being connected in that end portion, located between the conveyor outlet and the sieve, and
- d) a mechanical impact device for providing mechanical impacts to the pre-sieve (3).
The method of 15, characterized in that the separation includes a step of using a magnetic separator (12) comprising a field strength of 2,000 Gauss or more, preferably 4,500 Gauss or more.
