Abstract
A process for conveying solid particles of irregular geometry, preferably polygonal geometry, through a pipe system, where the solid particles are conveyed by a gas. In order to enable metering through fragments or other solid particles of irregular geometry in desired quantities without any risk of the particles becoming trapped in the pipe system and causing blockages, further solid particles of regular geometry are added to the solids particles of irregular geometry.
Claims24
A process for conveying solid particles of irregular geometry through at least one pipe or pipe system having a curve or several curves and/or a kink or several kinks, where a fluid is used for conveying the solid particles,
- wherein, for conveying the solid particles of irregular geometry as first solid particles, second solid particles of regular geometry are admixed with them and wherein the solid particles are conveyed with gas as the fluid.
Process for manufacturing solid silicon by crystallization of the silicon from a silicon melt, where crystalline silicon grown from the silicon melt present in a container is supplied appropriately to the silicon melt comprising or containing solid material,
- wherein the solid material comprises or at least contains first and second solid particles, wherein the first solid particles comprise broken silicon material and the second solid particles have a spherical or ellipsoid geometry and wherein the solid material is conveyed by a fluid.
