Mining Machinery Manufacturers in the U.S.



January 17, 2023 - Mining is a vital and growing industry. It produces approximately 3.4 tons of coal and 40,000 pounds of minerals per year. Much of that product powers American households and industries. Almost every manufactured item holds some form of US-mined mineral, from your car’s battery to the electricity you use to power your life.

Mining machinery manufacturers supply the equipment for this thriving US industry.

The latest research from MNI shows a 1.67% growth in the number of US employees in the mining machinery manufacturing industry. US mining-machinery manufacturers do not support only US mining though. The study also shows that manufacturing as a whole exports only 29% of its final product. US mining machinery manufacturers, on the other hand, support the world by exporting 53% of their equipment.

The following are the largest mining machinery manufacturers based in the US by number of employees.
