Abstract

Embodiments herein relate to a particle separator 110 for use in a calcination system 100. The calcination system 100 comprises an electrically heated calcination reactor 108 configured to convert input material into calcination process products. The particle separator 110 comprises a chamber 401 configured to hold a fluid bed 402 of particles mixed with gas, into which fluid bed 402 gas is fluing from underneath 403, thereby separating smaller particles from larger particles by lifting said smaller particles upwards in the flow of gas. The fluid bed 402 is coupled to a transfer channel 404 arranged to provide the flow of the separated smaller particles mixed with gas to an injection arrangement 106 injecting the provided input material into said electrically heated calcination reactor 108.
