1. An integrated device for preparing magnesium hydride powder, characterized in that the device comprises:
a heating chamber used for heating a magnesium-based metal material to produce metal droplets;
a powder-making chamber comprising an atomizer used for atomizing the metal droplets which are then cooled to form a metal powder; and
a reaction chamber used for performing a hydrogenation reaction on the metal powder to form the magnesium hydride powder;
wherein the device further comprises a collection chamber between the powder-making chamber and the reaction chamber, and the collection chamber is used for collecting and screening the metal powder; a vibratile sieve is provided inside the collection chamber, wherein the sieve has a mesh aperture of 100-1000 mesh and vibrates for speeding up the screening of the metal powder by vibration of the sieve.
