Shandong Huamin Steel Ball Joint-stock Co., Ltd. is the largest manufacturer and exporter of grinding balls and grinding rods, it was established in 1986, and it already have 36 years grinding media experience. Our annual production capacity is 200,000tons, and products are mainly exported to America, Canada, Chile, South Africa, Australia, Guinea, Mali, Mongolia and so on.
We hold the only automatic roll forging machine for grinding steel ball in China which developed by ourselves. The raw materials that we use are high quality alloy steel. The hardness of grinding steel ball is high and steady; the toughness is good controlled by equipment. The quality of our products can meet different requirements of clients in different countries and regions.
1. Forged grinding steel balls
Want higher grinding efficiency? For gold mining or cement industry? Then you can choose forged grinding steel balls, which are available in all stages of milling.
Huamin forged steel ball can be divided into low carbon, medium carbon, high carbon steel ball based on the carbon percentage.
The carbon content is below 1.2%. The chromium content is 0.1%-1.3%.
2. Cast grinding steel balls
As another type of grinding media, cast grinding steel balls can provide Cr (1%-28%), hardness (HRC40-66), and Diameter (10mm-150mm) alloy cast steel balls.
They can be divided into low chromium, medium chromium, high chromium, super high chromium grinding ball (CR20%-28%).
The forged steel grinding ball is excellent in surface quality, toughness, and resistance to impact and abrasion. It won't crack and lose circularity easily.
1) In general, forged grinding steel ball has high hardness: Surface hardness to 55-67 HRC, volume hardness of 56-64 HRC
2) impact toughness high: Impact toughness more than 12 J / cm2.
3) broken rate is low: Peel fragmentation resistance property of over 20000 times. The actual breakage rate not greater than 1% and close to 0.
