Process for the continuous preparation of filler-containing rubber powders, wherein a filler suspension and rubber latex are mixed 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 point of variable throttle cross-section provided in the tube. The throttle cross-section is adjusted with the proviso that the drop in pressure in the liquid mixture achieved with the throttle point is greater than 0.5 bar.
