In an embodiment, the system includes a sortation station, a screening apparatus, an air classifier, and a crushing apparatus to provide as output substantially pure cullet having at least two colors.

The invention relates to a method for separating black and white tungsten bulk flotation rough concentrates. The method is characterized in that a black tungsten rough concentrate and a white tungsten rough concentrate are obtained by virtue of high-gradient magnetic separation, roughing or roughing and scavenging; black tungsten concentrates and black tungsten cleaner tailings are obtained via carrying out once roughing, three-time scavenging and four-time concentrating on the black tungsten rough concentrate by utilizing sodium fluosilicate, sodium silicate, aluminum sulfate, lead nitrate, benzohydroxamic acid and sulfated nascent soap; white tungsten concentrates and white tungsten cleaner tailings are obtained via carrying out once roughing, three-time scavenging and three-time concentrating on the white tungsten rough concentrate after the white tungsten rough concentrate is heated up and stirred by utilizing sulfated fatty acid soap, sodium silicate, caustic soda and sodium sulfide; cassiterites in the white tungsten cleaner tailings are recovered by a table concentrator. The method related by the invention has the advantages of small mutual interference of black tungsten ore and white tungsten ore in the black and white tungsten bulk flotation rough concentrates, high recovery ratio of black tungsten ore and high and stable quality of the black tungsten ore; and the method is suitable for the black and white tungsten bulk flotation rough concentrates containing 5-40% of WO3.

The invention is an apparatus having first and second legs pivotable with respect one another about a pivot axis. The first and second legs pivot between a first position and a second position. In the first position, the first and second legs are substantially aligned with respect to one another and can be stored. In the second position, the first and second legs are transverse with respect to one another and can receive a bag. The apparatus also includes first and second incurvate portions defined by each of the first and second legs. The first and second incurvate portions are spaced from the pivot axis and from each other. The apparatus also includes first and second excurvate portions defined by each of the first and second legs. The first and second excurvate portions are substantially coplanar with the first and second incurvate portions of the respective leg and are spaced from said pivot axis and from each other. An opening of a bag can be received at the first and second excurvate portions and supported during filling.

The present invention provides methods and apparatus for removing oil and oil containment for oil spills using crushed glass.

Clean glass particles are produced from post-consumer mixed glass and like waste streams by a series of pulverizing, size- and material-based separation, ozonation, drying, sizing, and paper fluff removal steps.

Systems and methods for sorting a plurality of recyclable items in a single-stream materials recovery facility (SSMRF) are provided. In some embodiments, a system includes an infeed conveying system, a fiber transfer conveyor, a container transfer conveyor, and a glass sorting and conveying system. The system further includes a controller configured to obtain total weight and volume of recyclable items at the infeed conveying system. The controller estimates a percent weight of fiber items and a percent weight of non-fiber items relative to the total weight. Based on the estimates, the controller controls speed of at least one of the infeed conveying system, the fiber transfer conveyor, the container transfer conveyor, and the glass sorting and conveying system.

Clean glass particles are produced from post-consumer mixed glass and like waste streams by a series of pulverizing, size- and material-based separation, ozonation, drying, sizing, and paper fluff removal steps.

An ultra-strong tear resistant, cut resistant, puncture resistant bag having a high shear strength or modulus is provided by weaving ribbons of flat polypropylene sheet into a bag. The bag is formed by weaving a cylindrically shaped object, cutting the object transversely and sealing up one end to form the bag. The physical properties of the ribbon-woven bag easily accommodate holding refuse including bricks, wood with nails, glass and other refuse in a lightweight disposable bag. In an alternative embodiment, the ribbon-woven bag is overlain with sheets laminated to the exterior of the bag to provide a fluid-tight container.

The invention discloses an intelligent bottle classified recycling machine. The intelligent bottle classified recycling machine comprises a first movable baffle, a second movable baffle, a metal sensor, a metal bottle collecting cavity, a magnetic sensor, a non-metal bottle collecting cavity, a photoelectric sensor, bottle storage containers and a guiding conveying module, wherein the second movable baffle and the first movable baffle form a metal detecting cavity with the upper portion wide and the lower portion narrow so that bottles entering the metal detecting cavity can be concentrated at the bottom; the metal sensor is installed at the bottom of the metal detecting cavity; the metal bottle collecting cavity is located below the first movable baffle; the magnetic sensor is installed at the bottom of the metal bottle collecting cavity; the non-metal bottle collecting cavity is located below the second movable baffle; the photoelectric sensor is installed at the bottom of the metal bottle collecting cavity and used for detecting whether the bottles are made of a glass material or not; and the four bottle storage containers are located below the non-metal bottle collecting cavity and the metal bottle collecting cavity, and bottle inlets are formed in the tops of the bottle storage containers. According to the recycling machine, four kinds of bottles can be distinguished through two-stage detection and can be stored in a classified manner, a reasonable structural layout is combined with a sensor technology, material distinguishing is efficient and accurate, the overall structure is compact, and the occupied space is small.

The invention provides systems and methods for obtaining recycled mixed cullet at a beneficiator. The recycled mixed cullet can be used by glass plants to make new glass articles, such as beverage bottles.

To reuse glass used in a flat panel display, processing suitable for global environment such as processing of separating a lead component must be realized. A disassembly processing method for a flat panel display having a structure in which a face plate and rear plate mainly containing glass are airtightly joined via a frame with frit glass is characterized by including the step of separating the face plate and rear plate joined with the frit glass. The separation step is characterized by separating the face plate and rear plate by cutting, dissolution, or melting.

A crushing machine for comminuting laminated glass, particularly windshields for cars, consists of a chamber with cylindric wall (24) in which is suspended a rotor (28) with pivotably beaters (50). Plural layers of laminated glass are fed through a feeding opening (20) through rubber rollers (22) which form an almost airtight lock into the crushing chamber. At the inner side of its wall (24), the chamber is provided with a number of evenly distributed ribs (54) to be impacted by laminated glass pieces, which are subsequently further comminuted by the beaters (50). The crushing chamber is provided with a slot-formed discharge opening (34) which may be varied in width. Outside the discharge opening (34), there is mounted a collecting containing (36) provided with subpressure. Due to naturally occurring leaks in the wall (24) of the crushing chamber, including the feeding opening (22), there will be a continuous flow of air out through the opening (34), why the material will eventually be conducted therethrough and collected in a container (36). From here, the material may leave the container (36) through an aperture closed by a flap (38). With the crushing machine according to the invention, there may be achieved a complete comminution of laminated glass material and separation of glass from the plastic film in one step and so that the finest glass particles have a size in the order of 0-3 millimeters.
