Abstract

The invention relates to a corrosion-resistant filler production process. The production process comprises the steps of proportioning; pulverizing; mixing and performing ball milling; adding water; refining mud; forming; drying at low temperature; putting into a kiln; firing; and the like. Since the step of pulverizing is performed before the step of mixing and performing ball milling in the filler processing course, the pulverizing efficiency is improved, so that raw materials can quickly reach the required particle size; and since the surface of the filler is coated with an antifriction metal coating, the corrosion resistance and strength of the filler are further enhanced.
