A measuring unit 13 is provided inside a rotary drum 11. The measuring unit 13 is provided with a light transmitting member 13 a and an optical sensor 13 b that are provided at the central region on the inner wall of the other end portion 11 b. When particles are subjected to a coating treatment, information as to the properties (such as the coating thickness, the moisture, the coating performance, and the impurity) of the particles of a particle layer A being brought into contact with the surface of the light transmitting member 13 a is measured on a real-time basis by the NIR sensor 13 b via the light transmitting member 13 a. The data is processed by the processing unit of the NRI spectroscopic analyzer to thereby perform monitoring. By appropriately adjusting the coating operation conditions (such as the supplied air volume, the supplied air temperature, the spraying condition, and the rotation speed of the rotary drum 1 ) by feedback control or a manual operation according to the result, it becomes possible to perform the coating treatment of high quality.

A spherical tungsten carbide powder is characterized by that the material has a microhardness higher than 3600 kgf/mm 2 , and that the powder has an apparent density from 9.80 to 11.56 g/cm 3 . A method for the manufacture of a powder comprises the steps: a) providing a chamber comprising a rotatable crucible, b) adding material into said rotatable crucible, c) melting the material using a plasma arc discharge, d) rotating the crucible to atomize the molten material to form liquid droplets, with subsequent cooling of the droplets to obtain a powder, wherein the material added into said rotatable crucible is heated to a temperature above 40% of the melting temperature of the material before it enters the crucible. It is possible to reduce the current required for melting the stock. Heat losses are decreased, and the spherical powder obtained during atomization becomes more homogeneous in its composition and structure. The cost is reduced.

A method for atomizing a liquid (L) in a spraying nozzle (), wherein a gaseous phase (G) and a liquid (L) are fed to a mixing chamber () inside a nozzle (), obtaining an emulsion of the gas in the liquid, the emulsion being under pressure inside the chamber and formed by gas bubbles enveloped by the liquid in a film state. The speed of the gaseous phase at the inlet of the mixing chamber is around the speed of sound or greater. The atomized liquid is obtained by an expansion of the emulsion at the outlet of the chamber. A suitable nozzle () is also disclosed, comprising a mixing chamber () and a distribution device (D) adapted to provide appropriate gas and liquid feed to form an emulsion. 1. A spraying nozzle for atomizing a liquid , the nozzle comprising:a gas inlet passage;a liquid feeding passage; anda mixing chamber in fluid communication with said gas passage and liquid passage, by means of a gas and liquid distribution device arranged to provide a high-speed gas inlet in an inlet zone of said chamber, and a slower liquid inlet at the same inlet zone of the chamber, to form an emulsion of the gas in the liquid in said mixing chamber.2. The nozzle according to claim 1 , wherein said gas and liquid distribution device is arranged to provide that the liquid inlet is distributed in a symmetrical way around said gas inlet in the inlet zone of the chamber.3. The nozzle according to claim 2 , wherein said gas and liquid distribution device is arranged to provide a plurality of gas jets surrounded by a liquid flow distributed over a circumference claim 2 , at said inlet zone of the mixing chamber.4. The nozzle according to claim 1 , wherein said gas and liquid distribution device comprises a sleeve and a pin claim 1 , the pin being coaxially inserted into said sleeve claim 1 , and wherein:the sleeve has an axial gas passage with a rear opening in communication with the gas inlet, and a front opening with an internal rounded edge and in communication with the mixing ...
