Method for conveying silicon granules in an encapsulated conveying channel

A method for conveying granulated silicon by means of horizontal and/or vertical movement of a conveying device having a conveying channel for silicon granules, wherein the conveying device is completely encapsulated with respect to the outside, comprising providing an encapsulated conveying device having a conveying channel, introducing solar grade and/or hyperpure elemental silicon granules into the conveying channel, exciting at least one permanent magnet fitted to the conveying device by means of an alternating electromagnetic field, the electromagnetic field being applied to the encapsulated device externally, the alternating electromagenetic field, swaying the conveying channel, imparting a forward movement of silicon granules and thereby conveying the silicon granules through the conveying device by means of said swaying movement into or out of a fluidized bed reactor.
