Superior grinding media from Forsbacka Kulverk
Grinding Media
As a supplier of hot-rolled grinding media to a number of the world’s leading mining and recycling customers, our wear-resistant grinding balls and rods are the result of decades of experience meeting the industry’s highest demands.
Controlling the microstructure
Whether wet grinding ore for iron, copper or gold production, or dry grinding recycled glass or softer materials, even the slightest variations in steel chemistry and microstructure can have dramatic impacts on wear resistance.
Superior hardness
This is why, in addition to their superior hardness, our high-carbon grinding balls are rigorously controlled to ensure consistent rolling, tempering and quenching for optimal wear resistance in every batch. Likewise, our tailor-made rod grinders are delivered as rolled, in a wide range of dimensions, with hardness levels up to 688-739 HBW (62-65 HRC). The result is one of the market’s broadest portfolios of supremely robust grinding media, reliably processed, tailored and delivered to guarantee your long-lasting performance.
Optimized performance
Forsbacka Kulverk combines know-how in steel making and nearly 100 years of experience manufacturing of grinding media, selecting the right steel grade together with the correct processing and heat treatment parameters in order to optimize performance under different working conditions.
Wear resistance
For a given grinding ball – steel chemistry and micro structure are the dominant factors for controlling wear resistance. Increasing hardness leads to improved wear resistance.
