Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for directly producing a low dust silane-modified oxidic or siliceous filler, which can be used in a rubber mixture, from a low dust microbeads-like or microgranular oxidic or siliceous filler. SOLUTION: The silane-modified oxidic or siliceous filler, which has a less than 75 μm beads fraction of under 15 mass% and a median value of particle size distribution of 150-500 μm, is obtained by reacting at least one of microbeads-like or microgranular oxidic or siliceous filler with at least one of silanes in a compressed gas.
