Ball Mills or Rod Mills in a complete range of sizes up to 10′ diameter x 20′ long, offer features of operation and convertibility to meet your exact needs. They may be used for pulverizing and either wet or dry grinding systems. Mills are available in both light-duty and heavy-duty construction to meet your specific requirements.

The mechanical fine impact mill or centrifugal mill is usually operated in the form of a pin disc mill, blast mill, wing beater mill or grooved disc mill. Many products and finenesses for a wide variety of applications are processed with the universal mill, with a wide range of rotor and stator combinations that can be easily changed.

Once the mill was lowered, a Goldhofer hydraulic platform trailer carefully drove the ball mill out of the structure. There were tight clearances on all sides. Barnhart was hired to remove and replace a 467,000-pound ball mill measuring 45' long by 14' in diameter in a cement manufacturing plant during an outage. The customer needed a

Cobalt Steel Ball End Mills with Two Milling Ends. With better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as iron, hardened steel, titanium, and tool steel. When one end wears out, turn the tool around for a sharp edge.
