Fabrication of a Ball Mill

At Imperial Steel we fabricate tanks, reactors, pressure vessels and other equipment for industry leading manufacturers around the country. The stainless steel vessel shown here is a ball mill, which is used to grind raw materials into a fine powder. This powder is then used in a variety of applications such as mineral dressing processes, coatings and selective laser sintering. With in-house engineering capabilities, we are able to design and fabricate complex steel equipment for a variety of applications.

The body of the mill is constructed of 0.5" thick 304 stainless steel plate. Pieces were cut, bent, and rolled in-house before the mill assembly was welded. An insulation skin was applied to the mill for functionality. The finished mill has an outside diameter of 35", an inside diameter of 32" and a length of 51.75". Tolerances were held to ±0.125" in critical locations and verified by dimensional inspection.

We specialize in providing high quality custom fabrications that equal or exceed customer expectations. Our comprehensive fabrication capabilities allow us to customize all parts rather than limiting ourselves to off the shelf components. For additional details about this custom stainless steel fabrication project, see the table below, or contact us directly.
