    摘要: A rapid reduction apparatus and method includes a reduction and classification apparatus (20) having a reducing unit (22) composed of a contraction cone (28) for receiving the material to be processed. The contraction cone (28) is connected to an expansion cone (32) through an intermediate venturi section (30). Air is drawn through the venturi section and the expansion cone (32) by a turbine (34) mounted below the expansion cone. A standing shock wave (310) is established in the expansion cone, and material loaded into the expansion cone is disintegrated and reduced as a result of attrition grinding within the shock wave and upon contact with the blades of the turbine. The reduced material is then discharged into the classifier assembly (50) where the particles and air flow undergo a series of vertical motion reversals defined by a plurality of baffles (112-128) extending alternately from the top and bottom of the classifier assembly (50). Each reverse in the air flow is accompanied with flow friction losses, thereby reducing wind velocity and applied particle pressure resulting in the discharge of particles of equivalent size and weight into corresponding hoppers (86-96) spaced along the flow path and substantially below each baffle extending from the top of the classifier assembly.

    摘要: An apparatus for separating debris from spent abrasive in an abrasive blasting apparatus in which the debris and spent abrasive are recirculated from a blast zone at high velocity along a recirculation chamber includes means for receiving debris and spent abrasive from the recirculation chamber and allowing a quantity of the debris and spent abrasive to collect thereby forming a pile having a face exposed to incoming debris and spent abrasive. The pile has an angle of repose, whereby additional incoming debris and sent abrasive fall down the face to form a substantially unobstructed, vertical, uniform curtain of falling debris and spent abrasive. Means for providing a stream of fluid through the recirculation chamber are provided. Means having first and second openings are provided for drawing off the stream of fluid, which is divided into portions, from the recirculation chamber. The falling curtain of debris and spent abrasive is washed by the stream of fluid as it passes from the recirculation chamber to the drawing means to entrain the debris from the falling curtain in the stream of fluid.

    摘要: When a thermoplastic resin pellet is transported by air current, a floss is formed in pellet in a slight amount, which is flake-like or string-like and causes various troubles in the subsequent operations.A floss separator having a small size, a light weight and a superior floss-separation efficiency is provided.This separator consists mainly of a lower cylindrical column and an upper cylindrical chamber connected thereto, and further a specific inlet for introducing a mixture of air or nitrogen gas with a floss-containing pellet into the column and for imparting to the mixture, a helical ascending gas current, and baffles fixed onto the inner wall of the column at the upper end part thereof and counter-radially protruded therefrom, and having a specified angle of attack and a specified sweptback angle to the gas current line of the gas mixture, and also having a blow-through part formed by said baffles and the upper end part of the column. Pellet falls and separates at the baffles, while floss together with the gas pass therethrough.

    摘要: A fluid, such as air or water, carrying suspended solids is directed between a pair of oppositely charged, corrugated surfaces in order to subject the flow to an undulating action that increases the frequency with which the solid particles impinge against one another, thereby increasing the rate of flocculation of the solids. In the case of airborne particles, the corrugated surfaces are arranged in an upright condition so that the flocculated particles attracted to one or the other of such surfaces gravitate therefrom into a conveying mechanism that delivers such particles to a collecting receptacle. In the case of liquid-borne particles, the flow is forced to travel upwardly against the force of gravity after passing between the surfaces, thereby encouraging the flocculated particles to settle out into a sump that is associated with the uphill flow passage. In each case, two sets of charged surfaces may be utilized, the first having at least one of its surfaces insulated from the flow for electrostatic action only, while the second has neither surfaces so insulated for electrolytic action.
