A process for separating synthetic turf product comprising includes the consecutive steps of: (a) downsizing the synthetic turf product into a downsized turf material; (b) separating the downsized turf material by sieving into at least a first fraction substantially comprising a mixture of backing material and additional components and a second fraction substantially comprising grass fiber components; (c) separating the first fraction by specific gravity to provide a low density fraction and a high density fraction; (d) separating the second fraction by specific gravity and size by providing an airflow directed upwards in a separator configured to cause a swirling motion whereby a lighter fraction is entrained upwards in the air flow and a heavy fraction is allowed to fall downwards; and (e) collecting the low density fraction and the light fraction.

A multi-deck screening assembly includes a plurality of vertically-stacked downwardly-sloping screen decks, each with grading apertures through which under-sized material may pass, while over-sized material passes over a lower discharge end of each screen deck. The screen decks are mounted on a common frame, which is mounted on a chassis and provided with vibration device. The screen decks include an upper deck, an intermediate deck below for receiving under-sized material from the upper deck, and a lower deck below the intermediate deck for receiving under-sized material from the intermediate screen deck. A first chassis-mounted stockpile conveyor receives over-sized material from the lower deck, a second chassis-mounted stockpile conveyor receives over-sized material from the intermediate deck, and a third stockpile conveyor receives over-sized material from the upper deck. A transfer conveyor is operable to deliver over-sized material from the discharge end of the upper deck onto the third stockpile conveyor.

A sheet manufacturing apparatus includes a classifier unit configured to classify by air flow an introduced material that has been introduced, a screening unit configured to allow a classified material, which comprises fibers, that has been classified by the classifier unit to pass through a plurality of openings to screen the classified material, and a forming unit configured to use a passed material that has passed through the openings to form a sheet. The classified material is supplied to the screening unit by the air flow.

The invention relates to a system for the gravimetric sorting of a mixture of substances during the processing and/or the recycling of residual building materials and/or demolition materials, comprising a fractioning unit (2) adapted to divide the mixture of substances into at least m fractions (A, B, C); at least n.Math.m gravimetric densimetric tables (A.1, A.2.2, A.3.2), arranged in m cascades each with at least n densimetric tables distributed to n stages, wherein the fractioning unit is coupled to them densimetric tables (A.1) of the first stage such that a different one of the at least m fractions can be supplied to each of the densimetric tables of the first stage; wherein, within each cascade, each densimetric table of a considered stage (A.2.2, A.3.2) is coupled to a densimetric table (A.1, A.2.2) of the preceding stage such that either the first partial fraction or the second partial fraction (12, 22) of the densimetric table (A.1, A.2.2) of the preceding stage can be supplied to the densimetric table (A.2.2, A.3.2) of the considered stage. An appropriate method is also part of the invention.

A device for classifying a material mixture of multiple materials has a first transport unit into which the material mixture to be classified is deposited by a supply device. A second transport unit is arranged downstream. A first chute is provided between the first and second transport, via which a first material with a first fluid resistance can be separated from the material mixture. At least one third transport unit is arranged downstream of the second transport unit, such that a transit route for the materials is formed between the second and third transport units. A second chute is provided between the second and third transport units, via which at least the second material with a second fluid resistance can be separated from the material mixture. The third transport unit is designed so that material can pass through and/or a fluid flow can pass through.

The invention relates to a device and a method for separating and/or recovering silicate particles from plant material. This device and the method are characterized by an air classifier (3, 14), which has at least one material inlet (4), an air inlet (6), arranged under the material inlet (4), an air outlet (7) and at least one particle receptacle (8), arranged under the air outlet, wherein the plant particles recovered from plant material by crushing can be subjected to an air stream in the air classifier (3, 14) in such a way that silicate particles contained in the plant material are removed by the air stream via the air outlet (7) and, as a result of gravitational force, the plant particles are received by the particle receptacle (8) arranged under the air outlet (7) and taken away.

A separator attachment for use with a vibratory apparatus, the attachment including a housing mountable to a vibratory apparatus below a material-conveying surface of the vibratory apparatus, the housing defining a pressure chamber with an inlet and an outlet. The housing has at least one wall with a wall surface having a first end disposed proximate to the outlet of the pressure chamber and a second end. The attachment also includes a deflector plate with a deflector plate surface having a first end disposed proximate to the outlet of the pressure chamber and a second end, the deflector plate surface facing the wall surface. The deflector plate is translatable relative to the at least one wall to vary the spacing between the deflector plate surface and the wall surface. A system including a vibratory apparatus and the attachment may also be defined.
