Development of recycling technology of WC Powder product for Sustainable in Industry

Abstract

This study is meant to help develops better facilities for Tungsten Carbide powder production process. The 10 kg-capacity machine used was able to produce 85 -95.49 percent purity Tungsten carbide powder. When measured, most of the particle sizes and distribution between 0.03-350.00 !lm. which are considered large sized. More than that, those tungsten carbide particles are contaminated by other kinds of metal especially Cobalt binder. We have tried to improve the Tungsten Carbide manufacturing processes by combining more steps including ball milling, drying and screening. After 24-hours ball milling process, the result showed that we were able to produce smaller Tungsten Carbide paliicles sizing from 0.025 to 30.00 ~lm. The obtained particles are also rounder and with 99.50 percent purity. They are also easier to grade. The Tungsten Carbide manufacturing technology yet needs a further development to eventually produce the desired hard material.
