Abstract
Abstract Separator for aggregate which is suitable to separate heavy aggregate, even in the form of dust, from organic material, compost or other like wastes and comprises: - a separation vessel (32) with water, - an immersion device (13), - a first weir (15) cooperating with a rotary drum (16), and - withdrawal means (25) cooperating with the bottom of the separation vessel (32). System to separate aggregate from the organic fraction capable of being composted and obtained by treating solid urban wastes, or like wastes, passed through a trituration process and a riddle, in which system a separator (10) for aggregate is employed to separate the various parts and uses water and compressed air for the separation.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
81 words
1 - Separator (10) for aggregate which is suitable to separate heavy aggregate, even in the form of dust, arriving from a trituration or riddling process, from organic material, compost or other like wastes,the separator being characterized in that it comprises in reciprocal cooperation: - a separation vessel (32) with water, - an immersion device (13), - a first weir (15) cooperating with a rotary drum (16), and - withdrawal means (25) cooperating with the bottom of the separation vessel (32).
Claim 2
Dependent Claim

1 - Separator (10) for aggregate which is suitable to separate heavy aggregate, even in the form of dust, arriving from a trituration or riddling process, from organic material, compost or other like wastes,the separator being characterized in that it comprises in reciprocal cooperation: - a separation vessel (32) with water, - an immersion device (13), - a first weir (15) cooperating with a rotary drum (16), and - withdrawal means (25) cooperating with the bottom of the separation vessel (32).
Claim 3
Dependent Claim
34 words
2 - Separator (10) for aggregate as claimed in Claim 1, in which a dropping zone (12) for aggregate is comprised between a zone (22-24) for immission of water and the immersion device (13).
Claim 4
Dependent Claim
30 words
3 - Separator (10) for aggregate as claimed in Claim 1 or 2, in which the rotary drum (16) cooperates with a doctor knife (17) and a precipitation vessel (20).

4 - Separator (10) for aggregate as claimed in any claim hereinbefore, in which the precipitation vessel (20) comprises a second weir (19) and is connected to a collection vessel (29).
Claim 6
Dependent Claim
32 words
5 - Separator (10) for aggregate as claimed in any claim hereinbefore, in which a means (18) to extract heavy fines which cannot be composted is included in the precipitation vessel (20).
Claim 7
Dependent Claim
25 words
6 - Separator (10) for aggregate as claimed in any claim hereinbefore, in which the collection vessel (29) contains a means (30) to extract sludges.
Claim 8
Dependent Claim

Claim 10
Dependent Claim
51 words
9 - Separator (10) for aggregate as claimed in any claim hereinbefore, in which a pre-wash (22) is provided, downstream of the dropping zone of the material to be treated (12), in cooperation with the neighbourhood of the outlet from the water of the material engaged by the withdrawal means (25).
Claim 11
Dependent Claim

12 - Separator (10) for aggregate as claimed in any claim hereinbefore, in which at least the surface flow of the water in the separation vessel (32) is a one-way flow towards the immersion device (13) and thereafter towards a first weir (15).
Claim 14
Dependent Claim
114 words
13 - System to separate aggregate from the organic fraction capable of being composted and obtained by treating solid urban wastes, or like wastes, passed through a trituration process and a riddle with a separation of the various parts, and by sending thereafter the fraction which can be composted to a maturing process after passing through a process of mixing with organic material of a greater piece size, and/or with biological sludges, and/or with material to initiate fermentation, and/or with an addition of water to adjust humidity, the system being characterized in that a separator (10) for aggregate which employs water and compressed air for the separation is used to separate the various parts.
