Abstract
A continuous electrical discharge arc column is moved bodily through a closed arcuate path. Particulate material is fed into the moving column at an angle such that the particles of the material travel through the column in substantially spiral paths. After emerging from the column, the arc treated particles are collected at a point of deposit spaced vertically below the column. During its movement, which is at a controlled rate, the arc column is expanded.
