| PROBLEM TO BE SOLVED: To obtain a coarse aggregate and a fine aggregate free from the admixture of cement paste particles, sight in attached cement paste, simply regenerate and produce a high-quality coarse aggregate slight in attached cement paste, by grinding a concrete waste into a specific size, classifying the ground particles, recovering particles having specific particle diameters as a coarse aggregate and a fine aggregate, respectively, classifying particles having particle diameters smaller than a specific particle diameter by using a centrifugal air classifier and recovering particles having a prescribed specific gravity as the fine aggregate. SOLUTION: A concrete waste is ground into particles in the size of about 0.8-1.2 times as much as the maximum diameter of the aggregate contained in the waste by using, for example, a jaw crusher. The crushed material is classified, for example, by a vibrating screen, particles having >=5 mm particle diameter are recovered as a coarse aggregate and particles having 0.6 mm to <5 mm particle diameter as a fine aggregate. Particles having <0.6 mm are classified by using a centrifugal air classifier and particles having >=0.15 mm particle diameter are recovered as the fine aggregate. A cement paste material attached to the aggregate can be released by using the centrifugal air classifier. | ||||||

| Described is filter matting (20) for reversible-flow filter, the matting having layers with decreasing mesh size disposed on a rigid base (21). The matting layers are joined to each other and to the base preferably by means of sintered joints and hence braced with respect to each other. Particularly preferred is the use of such filter matting in the operation of a pressure filter which can be fitted with equipment for automatically removing the filter cake. Because of the rigid nature of the filter matting, a reverse flow can be established using a liquid or gaseous flushing agent to detach the filter cake rapidly and completely, without the filter matting being distorted or torn open. Any residual layer of filter cake is removed by using a swirling flow. The use of heated gaseous flushing agent enables the filter cake residues to be dried more rapidly. | ||||||

| PURPOSE: To regulate a grain sieving effect at a velocity of an ascending stream by passing the sand stream of sand mixed with dust on the horizontal or slightly inclined surface of a sieving bed for particles heavier than sand particles and using the ascending stream as a carrier stream for the dust components. CONSTITUTION: An air permeable intermediate plate or temporary bottom 16 having a transverse direction grid 17 and a longitudinal direction grid is fixed spatially from a bottom plate 12 to a housing wall body in a housing 10 and the sieving bed 18 for pellets or balls of copper or steel is placed on the intermediate plate 16. Air is introduced in an arrow X direction by an air feed conduit 40 having a throttling member 38 into the bottom space 20 of the housing and is blown through the sieving bed 18. The intermediate plate 16 is connected to a knocking mechanism. The air flows through a sand-dust bed 36 and entrains the dust toward the air groove holes 24 of a guide pipe 26. The dust is transported by the air (arrow Z) of the guide pipe 26. The mixture composed of the sand and dust introduced by a sand introducing means 30 is separated on the sieving bed 18 and the sand is discharged from a sand discharge port 34.

| PURPOSE: To make constant the amt. of production and to improve the accuracy of layer formation and treating capacity by providing a second coal discharging device just behind a bed-height detector and controlling the amt. of coal feed of a coal feeder and the amt. of coal discharge by the detected signal of the bed- height. CONSTITUTION: A float 1 is disposed in the material 28 fluidized in a coal washer. The vertical movement of the float 1 is transmitted to the bed-height detector 2 and transmitted further to a controller 9 through a signal convertor 7 and an analog memory 8. Then, a positioner 12 is operated by the control module 11 to open a slide gate 3 and move a rotary gate 4 vertically and control the discharge of coal 29. Thus, only the washed coal 27 is sent to the next tank. In this case, a second coal bed-height detector 17 and a coal discharge device 24 are provided to near a coal feeding port 30, and a motor 18 of the coal feeder 26 and a motor 25 of a coal discharge device 24 are controlled to adjust the feed amt. of the coal and the discharge amt. of the coal. Accordingly, the quantity and the quality of the coal grain on the bed after passing through the coal discharge device 24 are both held in constant range. COPYRIGHT: (C)1984,JPO&Japio | ||||||
