Provided is a coated granular fertilizer, which includes a granular fertilizer and a resin coat that coats the granular fertilizer, in which the resin coat contains a urethane resin that is a polyaddition product between a polyisocyanate component and a polyol component, the polyisocyanate component includes an aromatic polyisocyanate, and the polyol component includes a castor oil-modified diol, an alkylene diol having 2 to 8 carbon atoms, and a compound having three or more hydroxyl groups.

A method and a device for producing granulates (1) which are obtained by the method steps: intensively mixing raw materials (2) and optionally additives (6) by adding water (3) to form a mixture (4); introducing the mixture (4) and optional additives (6) into a granulator (11); granulating the mixture (4) by adding water (3) to form raw granulates (12); introducing the raw granulates (12), water (3) and optional additives (6) into a rolling drum (17) and rolling the raw granulates (12) to form the granulates (1).

A manufacturing method includes a granulation step. The granulation step is a step of forming a plurality of granules by performing extrusion granulation on a granulation material using a granulation machine. The granulation machine includes a die and a cutter. A through hole that allows the granulation material to pass therethrough is formed in the die. The cutter cuts the granulation material that has been extruded from the through hole while rotating along the back side of the die. In the granulation step, short-distance cutting in which the granulation material is cut while the cutter rotates within a first plane, and long-distance cutting in which the granulation material is cut while the cutter rotates within a second plane that is located farther away from the die than the first plane are executed.

The cutter cuts the granulation material that has been extruded from the through hole while rotating along the back side of the die. In the granulation step, low-speed cutting in which the granulation material is cut while the cutter rotates at a first speed, and high-speed cutting in which the granulation material is cut while the cutter rotates at a second speed that is higher than the first speed are executed.

Methods for forming multiphasic microparticles by using wettability engendered template self-assembly (WETS) techniques are provided. A template is used that defines wettable regions to polar and non-polar liquids and non-wettable regions to polar and non-polar liquids. A first liquid is applied to the template and forms a solid or semi-solid release layer. A second liquid is applied over the release layer to form a solid or semi-solid first layer and a third liquid is applied over the first layer to form a solid or semi-solid second layer. The first layer and the second layer can be released from the template by removing the release layer from the template with a treatment agent to form multiphasic microparticles. Methods for making the templates and multiphasic micro particles are also provided.

Provided is a device for granulating, agglomerating, pelletising, drying and/or coating, the device including a swirl chamber, a distribution chamber, wherein the swirl chamber is separated from the distribution chamber by a base and wherein a powder to be granulated or a powder mixture to be granulated is presented in the swirl chamber, the device further including at least one agitator for thoroughly mixing the powder to be granulated or the powder mixture to be granulated and at least one addition device for a liquid, wherein the base is designed in several parts and at least one base part is horizontally and/or vertically displaceable, with the result that that the base becomes a distributor plate. Also provided is a method for granulating, agglomerating, pelletising, drying and/or coating using such a device and a base suitable for use as a distributor plate in a convective drying apparatus.

A method of fabricating an electrically conductive loaded powder of thermoplastic polymers. The method comprises the steps of making an original powder containing cores made of thermoplastic polymers and of making the loaded powder by using electrically conductive submicrometer filaments and wax, forming a plurality of particulate compounds each comprising one of the cores together with at least one of the filaments and a protective membrane of the wax.

Disclosed is a particulate, urea-containing composition, to a method and apparatus for producing it, to the use thereof as fertilizer, as technical urea or as feed additive, and to the use of an additive for producing a particulate, urea-containing composition.

A method of forming a coating layer, including preparing hollow inorganic particles, each hollow inorganic particle including a shell surrounding a hollow core; preparing inorganic coating particles of a solid structure; forming a mixture of the hollow inorganic particles and the inorganic coating particles; and spraying the mixture on a surface of a base by a plasma spray coating process.
