A method is for recycling a roll of artificial turf. The method includes the steps of processing the roll of artificial turf to yield a mixture of a quantity of infill and a quantity of synthetic fibers, the quantity of infill having rubber, sand, and debris, passing the mixture through one or more screens to extract a percentage of the quantity of synthetic fibers from the mixture and yield a first remaining mixture, and substantially separating the first remaining mixture into pieces of rubber of a first volume, pieces of rubber of a second volume greater than the first volume, sand, debris, and the remaining percentage of the quantity of synthetic fibers.

A device and a method for the separation of elongated parts (long parts) from bulk materials. The device comprises a conveying device (1), a deflecting device (2) and a rake with webs (4) being oriented longitudinally to the conveying direction. According to the method, the bulk material is transported on the conveying device (1), and then long parts (10) are oriented by means of a deflecting device (2) transversely to the conveying direction. After passing through the deflecting device (2), the transversely oriented long parts are transferred to the rake (4) and discharged as coarse materials (7). Compact parts (11) fall through this rake and thus end up in the fine material (6).

Provided is a suction and separation composite tube, and a suction cleaning machine and a harvesting machine using the same, which are highly cost effective and are capable of, with a relatively simple structure to keep the manufacturing costs low, separating items of relatively small specific gravity from items of relatively large specific gravity even if the output of a motor is set high, and thus reducing the likelihood of clogging or the like of sucked objects and effectively preventing damage to or breakage of a fan and a fan casing. The suction and separation composite tube includes a connecting tube portion, a suction tube portion, and a separation tube portion. The suction tube portion or the separation tube portion is integrally continuous with the connecting tube portion at a distal end thereof. The suction tube portion and the separation tube portion are combined together at an intermediate portion or proximal end portion thereof. Using the fact that the flow velocity of airflow involving sucked objects that have been sucked from a suction port decreases at a combining portion, the sucked objects are separated into items of relatively small specific gravity and items of relatively large specific gravity.

A method for separating a particulate stream of an evaporite mineral feedstock, the method comprising passing the stream to an air classifier configured to separate the particulate stream into a fine component and a coarse component.

An apparatus includes a sampling probe having a first portion and a second portion. The first portion is configured to penetrate inside a wall of a duct having an inner chamber that is configured to carry a gas stream containing particulate matter therethrough. The first portion is further configured to divert a sample of the gas stream from the inner chamber of the duet to the second portion that extends from the wall of the duct opposite the inner chamber. The second portion of the sampling probe is configured to direct the sample of the gas stream in a first direction with a second direction corresponding to a direction of the gravitational force of the earth. A first ray corresponding to the first direction forms an angle with a second ray corresponding to the second direction. The angle is less than 90 degrees.
