Grinding balls for steel grinding machines (hereinafter referred to as grinding steel balls) are a kind of medium used in the ball grinding mill to grind the materials therein. With an annual capacity of 500,000 tons, the grinding steel ball is mainly used in mines, with products exported to Southeast Asia, Australia, Africa, North America, Central and South America and other countries and regions. It has become one of the largest production bases in the world, with exported products reaching 95%. Longteng grinding steel balls occupy most of the global high-end application markets.
- High precision control of product quality
- Base metal production lines of the wear-resisting material adopt a full set of short-stress rolling mill produced by Danieli Group, Italy. The base metal is made through continual rolling to realize high precision control of product quality.
- Hot rolled steel balls are made from round steel produced by steel mills through hot rolling and with whole process automation control. The ball is uniform in hardness, with the heart having high hardness, being low in broken rate, and high in impact value.

Product Feature
1)High quality
High quality comes from every working procedure for the control . Grinding ball have no great
differences in appearance, but in the actual effect of grinding efficiency is different, this is because
the raw material, heat treatment process, equipment automation level and other factors can lead to
the steel ball steel ball lapping efficiency differences, and ultimately affect the user cost of grinding .
Every working procedure we always follow the details of the accused, by providing more wear-
resisting of grinding ball to help customers to reduce the cost of grinding.
Product Specification / Models
1 > Raw material contrast
Ordinary company : directly using the scrap or various steel grades production, traditional little
involvement in the high rate of grinding materials research and development.
houde : have a deep cooperation with The Chinese academy of sciences and steel plant , according
to different industry standard have in-depth research and development, developed raw material
with higher grinding performance.
Application
2 > Heat treatment of contrast
Ordinary company : Usually use pure water cooling quenching with insulation barrels of tempering ,
the heat treatment method is easy to cause uneven hardness, the lack of resilience, steel ball high
broken rate in practical use.
houde : Closed cooling tower for effective control of quenching temperature within the scope of the
standard, the composite heat treatment technology can improve the internal organization of steel ball,
the ball while guarantee the hardness have sufficient toughness are less likely to break.
Other Information
3 > Production craft contrast
Ordinary company : degree of automation is less than manual intervention, there is no guarantee
that the stability of each batch steel ball.
houde : Fully automated production lines, greatly reduced the manual intervention, to ensure the
stability of different batch grinding steel ball quality.
