The present invention discloses a method and corresponding apparatus for separating lightweight materials from fabric pieces. The method comprises the steps of (a) introducing fabric pieces into a tumbling means having perforations for lightweight materials in the fabric pieces to be removed therethrough and coupled to a first source of negative pressure; (b) tumbling the fabric pieces in the tumbling means and simultaneously applying negative pressure from the first source of negative pressure to the tumbling means for removing lightweight particles detached from the tumbling fabric pieces from the tumbling means; (c) transporting the fabric pieces from the tumbling means to a top of a vertical separation chamber; and (d) applying forced air to the fabric pieces as the fabric pieces drop from the top to bottom of the vertical separation chamber by gravity for separating the lightweight materials from the fabric pieces, and simultaneously applying negative pressure from a second source of negative pressure to the vertical separation chamber to remove the lightweight materials separated from the fabric pieces from the vertical separation chamber; repeating this step until the fabric pieces are substantially cleared of any lightweight materials. The apparatus comprises a tumbling means and a vertical separation chamber.

A compact dedusting apparatus for cleaning particulate materials of contaminates and has a housing defining a cleaning area in which the contaminants are removed to create cleaned particulate material with a product discharge opening through which cleaned particulate material can be discharged. The dedusting apparatus includes an infeed apparatus having a vibratory feed pan powered by a vibration generator to induce vibrations therein. The dedusting apparatus also includes a Venturi chamber to remove contaminants from the particulate material by a flow of air passing upwardly through the product discharge opening. The dedusting apparatus further includes an interchangeable carryover deflector having a chamber extension member that aligns with internal structure to control the flow of particulate material into said Venturi chamber and deflects particulate material entrained in the air flow through the Venturi chamber toward the product discharge opening. The carryover deflector incorporates an observation window to view the dedusting operation.

An air wash abrasive particle separator apparatus which separates contaminants from previously-used abrasive particles contained in a contaminated abrasive particle mixture such that the abrasive particles may be re-used multiple times, the apparatus being in combination a contaminated abrasive particle mixture delivery device, an accumulator hopper assembly, a volume sensing device, an automatic flow control valve, a separator assembly and an air transfer device.

In a casting sand reclamation system and a casting sand reclamation method, an appropriate reclamation process is performed according to the properties of casting sand to improve the reclamation accuracy and the reclamation yield. Capacitance measuring devices 70 and 71 that measure the capacitance of casting sand 1 (recovered sand 1a or reclamation sand 1b) are arranged on an upstream side and a downstream side of a batch-type polishing device 7, and feedback control is performed based on the measurement results of the capacitances by these capacitance measuring devices 70 and 71. A sorting device 10 sorts the recovered sand 1a polished by the polishing device 7 into a sand grain component (reclamation sand) and a fine grain component (containing a binder), and has a capacity N times that of the polishing device 7. A control device 80 performs feedback control based on capacitance RU of the recovered sand 1a measured for each polishing process on an upstream side of the polishing device 7, and an average value of N capacitances RD of the reclamation sand 1b measured for each polishing process on a downstream side of the sorting device 10.

A hydraulic separation system and method enables efficient recycling of log yard waste from an elevated frame. The system separates fine granules, small rocks, small bark, large bark, and large rocks with a variety of sequentially positioned, hydraulically powered separating components. The separation is mechanical and the size and weight of the individual material determines where in the system it is separated. Conveyors carry the log yard waste through the system. Shaking screens shake in a fast, up and down motion to flip and move the material through the system. Adjustable sloped plates work to accelerate and decelerate the material through the system. Dampening fingers control the disposition of elongated pieces of large bark and help to decelerate down the material. Blowers separate the bark from heavier rock and granular material. The elevated frame to enable cleaning and access to materials discharged beneath the elevated frame.

A classifying device may be used to classify a granular material flow. The classifying device may comprise a first inlet that allows a first material flow into the classifying device, a second inlet that allows a second material flow into the classifying device, a static classifier, and a dynamic classifier. The static classifier may be positioned such that the static classifier at least partially surrounds the dynamic classifier. The classifying device may comprise a distributing device that is designed in such a manner that it supplies the material flow of the first inlet to the static classifier and the material flow of the second inlet to the dynamic classifier.
