70mm Forged Steel Grinding Balls in a Sudan Gold Mine

Project Overview

A leading gold mining company in Sudan aims to optimize the efficiency of its grinding circuit. The customer's existing cast balls are experiencing excessive damage (a loss of 3 - 5% per month). Each batch of processed ore requires a high consumption of 108 kilograms. Therefore, the customer's requirement is for 70mm forged steel balls for the coarse crushing of gold-bearing quartz ore.

SMAT Solution: High-quality Forged Grinding Balls

We supply 70mm high-carbon forged steel balls, featuring the following characteristics:
Outstanding material properties:
Composition: 60MnCr1 (Hardness 58 - 62 Brinell hardness)
Impact toughness: ≥ 12 joules per square centimeter

Precision Manufacturing:

Molded from steel billets through hot forging (without casting defects)
100% hardness testing and computer sorting are adopted

Customer Feedback
"The consistency of the forged steel balls eliminated the vibration problem in our mill. Just for the cost of the medium alone, we saved over 280,000 US dollars annually." - Dr. Abubakar, Chief Metallurgist
