Production technology: huamin mainly have three kind of production technology for forged steel balls. 1) air hammer forged steel balls 2) rolling-forged automatic production line designed by our ourselves, this production line is controlled by automatic equipment, so the hardness is high and toughness is good. 3) rotary-cut automatic production line, this production line gets five national patent. Currently, we mainly use this production line to produce forged steel balls, so the product quality is quite steady and good. 7. Inspection Huamin have a full set of inspection equipment.We can test hardness, hadness distribution, chemical composition, impact value, micro-structure, dropping test and so on. 8. Packing Huamin have two kinds of packing method: steel drums or container bags, this two kind of packing can both meet the requirement of repeated shipping and storage, customers can choose any one.

Introduction: Product description 1. Choosing the optimal grinding media - we can help you choose the correct media for your application based on ore characteristics and your mill 2. Improved production and energy efficiency - our tools allow us to identify the correct media and mill liner pairing 3. Lower total cost of ownership - the correct media choice coupled with our exact manufacturing maximizes wear life 4.Continuous improvement - our sophisticated monitoring tools coupled with wear performance simulation means we can continue helping optimize production Product name:forged grinding ball/casting steel ball/hot rolling grinding media balls for ball mills Material:b2, b3, b6, bu 45steel, high chrome, low chrome steel Surface hardness:hrc58-65 Volume hardness:hrc56-63 Impact toughness:18j/cm2 Breakage rate:less than 0.5% Annual out out:200, 000 tons Application:mines/cement plants/power stations/chemical industry, mines/cement plants/power stations/chemical industry
1 ) product feature 1 > high hardness: surface hardness: hrc57-67 hrc, volume hardness hrc56-64. 2 > high impact toughness: the impact toughness of our grinding balls is more than 12 j / cm2. 3 > low broken rate: the actual broken rate is not higher than 1%. 4 > good wear-resistant and lower wear rate.
Grinding steel ball include: forging steel grinding balls: dia 20mm --- dia 150mm; the high, medium and low Chrome alloyed casting iron balls: dia17mm --- dia 100mm. They mostly apply in various mines, cement plants, power stations, chemical industries etc. The specialties: high hardness, no breakage, good wear resistance, even wearing and also it has obtained a high reputation from customers in domestic and foreign market.
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.
