Abstract
A method and apparatus conveys solid particles from a supply device to a charging device for charging free-flowing cutting jets. Positive charging of the cutting jets even when located at a greater or remote distance from the supply device is ensured. To that end, the solid particles are transported in a closed circuit between the supply device and a charging or intermediate storage device and the momentarily required partial quantity of solid particles needed for charging the cutting jet is removed from the closed circuit.
