摘要:
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.
摘要:
In a coated particle, a surface of a base material particle is coated with a carbon particle. The carbon particle is produced by disposing an explosive substance with a detonation velocity of 6,300 m/sec or higher in a periphery of a raw material substance containing an aromatic compound having two or less nitro groups, and detonating the explosive substance.
摘要:
A particle with an environmentally friendly resin coating having very low levels of leachable compounds is disclosed. The water leachable phenolic content of the coated particle is low enough to eliminate problems with leaching of phenol or its derivatives into an aquifer during downhole applications. Processes for fully and partially coating the particle with the resin coating are also disclosed.

摘要:
Methods and system for increasing the water solubility and availability of zinc in granular fertilizers using acid treatments. The treatment of granular fertilizers with an acidic solution increases an amount of water-soluble zinc, which in turn, increases the efficiency of zinc uptake and reduces the costs and equipment otherwise needed to mitigate zinc deficiencies.
摘要:
A scalable method for the manufacture of narrow, bright, monodisperse, photo-luminescent quantum dots prepared in the presence of a Group II-VI molecular seeding cluster fabricated in situ from a zinc salt and a thiol or selenol compound. Exemplary quantum dots have a core containing indium, phosphorus, zinc and either sulfur or selenium.

摘要:
In a production process of granules containing a biologically active substance, variation in the elution profile of the biologically active substance is reduced by heating the temperature of granules to about 50° C. or higher and maintaining the temperature for about 1 minute or longer. By setting the spray speed to about 90 mg/min or more per 1 g of cores when a spray agent for a primary agent containing the biologically active substance is sprayed while spraying a binding liquid to the cores and setting the total feeding weight per unit area for a centrifugal fluidized bed coating granulation machine to about 1.5 g/cm2 or more, the variation in the elution profile of the biologically active substance from the granules is reduced.
