With the development of wet ball mill, advantage of forged steel ball is more and more obvious. Compared with casting ball, forging steel ball has all the advantages of steel. After heat treatment, it becomes ball milling of high quality. Steel ball of  Fareast Steel Balls Trading Ltd.has automatic production line, which reduce the production cost and improves the production efficiency. The company set up a academician workstation. Guided by University of Science and Technology Beijing doctoral tutor and academician of Chinese Academy of science academician Hu Zhenghuan, it takes in-depth development of ball milling. The team independently research and develop high wear-resistant alloy steel material series high-performance ball milling, which greatly reduce the production cost and is widely praised by domestic and foreign customers.



The ball mill can be divided into dry ball mill and wet ball mill according to the material’ wet and dry.



Dry ball mill has been widely used in cement, silicate products, new building materials, refractory materials, chemical fertilizer, black and non-ferrous metal processing and the glass ceramic production industry. In 1950s, about 70% are dry ball mill in foreign countries. With the progress of technology, as well as to the energy saving and environmental protection have become increasingly demanding, wet ball mill is developing rapidly, which now accounts for more than 75% of the total of ball mill.



 Hot rolled steel is a kind of wear resistant steel ball, which is originated from the former Soviet Union. In 1956, Handan Iron and steel introduced the production line.Steel Ball Mill Zhangqiu Dicheng Machinery Co., Ltd and academician of the Chinese Academy of Sciences, Professor Hu Zhenghuan of University of Science and Technology Beijing joint R & D together research the production line, which is of high production efficiency, high yield, production mechanization and high automation.



Hot rolled the ball forging (rolling) metallurgical industry standard steel ball black (YB/T 091-2005) specializing in the production of various specifications of hot-rolled steel ball milling. The ball diameter range of Φ 20- Φ 70mm. Blank rolling ball milling is used in hot rolling round steel of various chemical ingredients. Hot rolled steel production process is as follows:



1.After testing, round steel bar is sheared into steel ball billet according to the specified length.



2.Before rolling, steel ball billet is in continuous heating furnace to be heated to a suitable temperature.



3.After fed into the ball mill, red hot billet rotate and move between the 2 special spiral groove roller, and is continuously rolled into a ball.Milling and grinding media  Each ball mill per minute can roll 60-360 balls.



4.The rolling red hot ball immediate access to online heat treatment equipment, which is special design of the factory to under quenching and tempering heat treatment, so that the ball was very high and even hardness.



5.Qualified products are sent to the finished goods warehouse and packed to the customer.
