A process for continuous preparation of filler-containing rubber powders including mixing a filler suspension and rubber latex in the liquid phase. The liquid mixture is passed through a tube, at least a coagulant is added to the tube and filler-containing rubber particles are precipitated. The liquid mixture is passed through at least one throttle position of variable throttle cross-section provided in the tube. The throttle cross-section is adjusted so that the drop in pressure in the liquid mixture achieved across the throttle position is greater than 0.5 bar.
