摘要： A process for pelletizing sorptive mineral "fines" which includes adding sufficient moisture to the particles of sorptive material to occupy the pore space therein, compactly forming the moistened mineral in a pelletizing machine, then removing the pore moisture in a suitable dryer or kiln so that final pellets retain relatively the same absorbent capacity and bulk density as the original material.

摘要： Synthetic absorbent granules of calcium sulfate dihydrate are manufactured by a process which utilizes a commercial type of dry powdered gypsum plaster or calcium sulfate hemihydrate, mixes the plaster with water in an inclined rotating disc machine to cause hydration to occur, and wherein the plaster is formed and grown into balls or granules of a generally predetermined size and discharged from the disc when reaching such size. The ball forming operation is started in the disc with seed material in the form of balls of a size corresponding generally to the balls to be manufactured by the process. Water spray is applied to the seed material in the rotating disc and a uniform pattern of movement of such material with a well defined eye is developed. When this occurs, generally the water is turned off. Dry powdered gypsum plaster is fed to the rotating disc from a position adjacent the base of the eye and then water spray is fed to the disc through a nozzle located so that the water will not strike the eye formation of the moving material. With the plaster being fed to the disc the seed material balls grow to a size where they are discharged from the inclined rotating disc at a lower portion thereof, and meanwhile the dry powdered plaster coming in contact with the water spray forms into new tiny balls, and these grow as the mix moves in the inclined rotating disc until they reach a size at which they are discharged. During this operation, while the balls grow in size and the plaster is hydrating, the material in the disc is visually observed, and if the balls or granules are too dry that they are not growing, or if they are too wet that they stick together, of if the eye configuration in the moving material is not proper, adjustments are made in one or more of the processing conditions including the position or amount of the water spray, the position or amount of the plaster feed, the speed of rotation of the disc, or the inclination thereof. When the desired eye configuration is restored from needed adjustments, the balls or granules grow, they are discharged, and they are dried and then screened to the desired size, with large balls or granules crushed and again screened to the desired size. The screened synthetic balls or granules are ready for marketing and use as absorbents for various purposes including the absorbing of undesirable oil, grease and other liquid accumulation on floors, of animal toilet refuse as in cat boxes, and the serving as carriers for agricultural chemicals to be distributed in such granular form.

摘要： An apparatus suitable for making a granular absorbent from cellulosic fibrous material includes a housing which defines an elongated internal cavity, and an inlet and an outlet communicating with the internal cavity. A rotatably driven shaft extends within the cavity of the housing, with the apparatus including an impeller arrangement mounted on the shaft for rotation therewith. The impeller arrangement includes resiliently flexible bristles which cooperate with the interior surface of the internal cavity for effecting agitation, blending, and agglomeration of the cellulosic fibrous feed stock. A pellet-like granular absorbent is produced.

摘要： An absorbent article suitable for absorption of aqueous as well as oleaginous liquids such as metal cutting fluids, hydraulic fluids, oils and the like is disclosed. The absorbent article is a spunlaced material sleeve closed at both ends and filled with an inherently flameproof particulate material, such as particulate clay material, having a certain particle size range. The spunlaced material is liquid permeable, oleophilic, and hydrophilic. The spunlaced material also has a liquid wicking rate that is at least equal to that of the particulate clay material contained within the sleeve. Preferred spunlaced materials are woodpulp/polyester spunlaced materials having a woodpulp-rich face and a polyester-rich face. The polyester-rich face is situated contiguous to the particulate absorbent material.

摘要： The present invention is directed to substantially dust-free granules. The granules are constituted by a normally dusty inorganic solid material and a water-dispersible nonionic vinyl polymer distributed thereon. The vinyl polymer promotes retention of dust size particles to the granules of the inorganic solid material.
