Does the cast ball less corrosive affect the wear rate?

1. The wear rate of grinding balls on the condition of wet grinding is more serious than dry grinding.
2. In the case of wet grinding, the steel balls are corroded when coming into contact with acidic or alkaline substances . Wear and corrosion work together, and the grinding of the materials destroy the passivation film, which accelerates the corrosion . As a result, the wear of the steel ball under wet grinding conditions is significantly higher than the superposition value of corrosion and wear alone.
3. The cast ball is less corrosion resistant than forged ball. Under the combined effect of wear and corrosion, the wear of casting ball will doubled increase. The final wear rate is the same or higher than forged ball, but the cost of cast ball is 100-300USD/ton higher than that of the forged ball
On the conditon of wet grinding, forging ball is more economical and durable .
Shandong Shengye Grinding Ball Co., Ltd is located in the beautiful city: Zhangqiu District Jinan City. In China, we are a professional factory specializing in the production of forged and hot-rolled balls and alloy steel bars for the mills, with an annual output of 100,000 tons. More than 95% of the products are exported to more than 30 countries, with customers throughout Southeast Asia, Africa and Latin America. And we have a good business cooperation with the big renowned mining companies , cement plants , thermal and chemical power plants in China and worldwide, we have received favorable comments from them.
At present, the company has 10 production lines of forged and automatic hot rolling that are world advanced level, and produce grinding balls with diameters from 15 mm to 200 mm and several steel bars resistant to wear. Given that the company uses advanced technology and automated processes, the entire round bar is uniformly heated at one time to ensure each ball produced is of high quality.
