Fused Mineral Production Process
High-quality products start and end with a meticulous manufacturing process.
Raw Material Selection
Washington Mills carefully selects the finest raw materials, sourced from around the world
The materials are shipped directly to our fusion plants, where they are stored before processing.
Control from Start to Finish
Owning our own fusion plants has its advantages.
Owning our fusion plants gives us total process control from start to finish and ensures strict quality control over our crude production.
Electric Arc Fusion Expertise
Our state-of-the-art fusion plants are equipped with the latest furnacing technology and operated by our highly skilled furnace team.
Numerous computer-controlled furnaces ensure reserve capacity, allowing us to respond to the diverse material demands of our customers. Our furnacing process is operated under carefully controlled conditions to ensure high levels of purity in the quality of our finished products.
Crushing & Grading
We've been perfecting our abrasive grain and powder processing techniques for more than 150 years.
Through our continual innovation, we've developed some of the finest crushing and grading systems in the business.
After fusion, the solidified ingot undergoes various size reduction processes. Our high-capacity crushing and grading plants are equipped with advanced grain processing machinery, designed to shape and size the grain to your exact specifications.
The final materials are meticulously inspected to meet ANSI (North America), FEPA (Europe), JIS (Japan), or custom sizing standards and specifications.
