How to solve the problem of air permeability in coated Sand Technology
/in Castings, Producing grinding ball process /by Sara WuThe common defects and main causes in the process of using coated sand and the main causes of the name of the defect (1) the loose surface of the mold (core) core pressure is too high or too low; the molded exhaust is not smooth; the mold runs because of the big clearance of the […]
SAND-COATED IRON MOLD PRODUCTION LINE TECHNOLOGY
/in Producing grinding ball process /by Sara WuThroughout the production of wear-resistant ball casting from forging, sand casting, iron mold casting to the current sand-coated iron casting, each is a qualitative leap. With the development of new technology, there is still a small proportion of wear-resistant steel balls in the mining market because of their advantages in impact toughness, but the market […]
SAND-COATING PROCESS OF IRON MOULD TO GUIDE TRANSFORMATION OF GRINDING BALL PRODUCTION
/in Producing grinding ball process /by Sara WuSAND-COATING TECHNOLOGY IN IRON MOULD is a new technology for producing wear-resistant grinding balls. It has the advantages of both iron mould and sand mould. It has the characteristics of chilled iron mould, small stress and good toughness in Sand Mould Casting. This is a very big breakthrough in the production of wear-resistant grinding balls. In […]
Key points in the process of High Chromium Steel Ball Casting
/in Grinding media balls, Producing grinding ball process /by Sara WuGenerally speaking, the end customers of wear-resistant materials companies mainly include mining, cement, construction and power plants. The performance of the wear-resistant steel ball is related to the cost and benefit of the end-user enterprise. At present, with the technical improvement of wear-resistant casting companies, the replacement of low-efficiency steel balls with high-performance and high-grinding […]
The hardness of grinding media ball
/in Grinding media balls /by Sara WuKeep the hardness just right. When we choose wear-resisting grinding media ball, often be the hardness problem of the grinding media ball. About the hardness, not the bigger the better, is the appropriate hardness value. Simply put, the higher the hardness, the greater the impact reaction during the process of falling, increasing the ball loss. […]
