A system and method are directed toward the synthesis of polymeric capsules using a phase inversion process by extrusion of polymeric droplets through a syringe-needle assembly or an iris-shutter mechanism. The polymeric solution may be prepared by dissolving PAN (polyacrylonitrile) polymer in DMF (Dimethyl Formamide) solvent at high temperature through continuous stirring. Following preparation of the capsules, further treatment was initiated using triethylamine in gelation bath to make the final product an efficient removal agent of water hardness.

A coating apparatus and method are disclosed for coating tablets with a film, in which the tables transit through a drilled first container where they are coated, then exit the first container and are removed from a rotating element provided on the periphery of a plurality of removal members that are spaced angularly apart from one another, in which each removal member removes a quantity of tablets, raises the removed tables as far as a certain height and then discharges the tablets into a chute that conveys the tablets into a second rotating drilled container, with delicate transfer of the coated tablets from one container to the next.

The present invention refers to an agglomeration drum and to a procedure for the agglomeration of mineral inside said drum for the pretreatment of minerals, both of them mainly used in hydrometallurgy. Said drum and procedure use a system and a phase of recirculation of gases as part of the invention. Additionally, in the agglomeration procedure the process of chemical reactions occurring inside the agglomeration drum is included. The agglomeration drum, agglomeration procedure and the reactive process allow to obtaining uniform, stable and poorly degradable agglomerates that have a bigger agglomerate-reagent contact surface. The agglomerates or aggregates produced in the agglomeration drum and according to the process of the invention increase the extractive yield of the later leaching process, thus reducing the creation of preferred ways for the leaching solution in the leaching piles. In addition, the drum and procedure of the invention allow preventing the release of gases to the environment, having a gas recirculation system, which by being closed keeps gases inside the agglomeration drum and process. This recirculation of gases not only allows preventing the release of said gases to the environment, but it also reduces the operating costs by using the recirculated gases as part of the agglomeration process.

Spheroidal polymer beads having a uniform size are prepared by polymerizing uniformly sized monomer droplets formed by dispersing a polymerizable monomer phase over double-walled cylindrical cross-flow membrane into an suspension phase. A shear force is provided at a point of egression of the polymerizable monomer phase into the suspension phase, the direction of shear substantially perpendicular to the direction of egression of the monomer phase. The membrane is metallic and includes a superhydrophobic coating.

A method of creating an artificial turf infill comprising providing olive pit fragments from an oil extraction process employing compressing the olives for extracting the olive oil, and tumbling the olive pit fragments to smoothen sharp edges of the olive pit fragments to produce rounded olive pit fragments.

A process for the production of elemental sulphur-urea fertilizer products is described, comprising the preparation of molten urea; preparing a suspension of micronized sulphur particles with water; mixing the molten urea with suspension of micronized sulphur particles with water wherein the micronized sulphur particles substantially remain in micronized solid state; and spraying the mixture of molten urea and suspension of micronized sulphur particles with water into a granulator, wherein the water in the mixture is flashed off, resulting in the formation of sulphur-urea granules with an even distribution of urea and micronized sulphur particles. An elemental sulphur-urea fertilizer composition obtained by the process is also described.
