Grinding Media Balls, mill balls for ball mill, including casting balls and forged steel balls, tell you the difference and how to select.
According to the requirements of mechanical properties, after repeated tests, the following chemical composition and scope have been designed: Carbon is the basic element that affects its structure and properties and the important factor that affects the properties of alloy grinding balls. With the increase of carbon content, the EUTECTIC carbides increased and distributed in […]
Chen Mulin. Development & Application of As-cast Low Cr Alloy Ball. Development and application of as-cast low chrome alloy balls have been introduced. Proper chemical compositions and cast technology parameters have been via experiments determined to produce cast balls without heat treatment capable of being put into application in large and medium industrial ball crushers. With […]
In order to make use of the MQ-3 ball tester for the impact fatigue test, we produce an 80mmm size ball. 2.1 Smelting and casting The melting equipment is a medium frequency coreless induction furnace with a nominal capacity of 850kg, and the pouring equipment is a 1-ton tilting type crane ladle.
In recent years, high chromium metal mold casting grinding ball has been widely used. In cement, electric power and mining industry and in the water, mud production, replaced, the pebble ball has achieved significant social benefits, market demand, and increasing. How to ensure the quality and meet users’ needs, production process control has become a […]
There are many kinds of grinding media used in various ball mills at present. Among them is Martensite Ductile Iron Grinding Ball, high carbon low chromium table gold casting ball, P-Cu-ti multi-element, alloy casting ball, cr-v-ti casting ball, Cr-Mo-Cu self-cast iron grinding ball, multi-element table, gold cast steel meal ball, high chromium grinding ball, high […]
According to the actual situation of grinding ball production, the cause and effect analysis chart (see Fig. 5) is used to analyze and study the factors which may lead to slag inclusion and fly edge defects from five aspects: man, machine, material, method, and ring.
Jinduicheng Molybdenum Industry Group Co. , Ltd. Mechanical and Electrical Repair Factory (Shanxi Hua County, 714102) He Guoqiang, Wang Wei) Abstract: The main reasons which affect the surface quality of the casting grinding balls are analyzed and the corresponding countermeasures are made. The quality of the casting grinding ball, which is the most easily worn […]
The as-cast and austenitic matrix structure can be obtained through the reasonable design of the chemical composition, strict control of each element’s content, and rapid cooling process. The volume content of AUSTENITE is 55% ~ 70%, the amount of carbide is 20% ~ 26%.
Zhang Bao-jie , QIAO Xiao2ai , Liu Wen-hui ( Shanxi Linfen Mechanical Casting Factory , Linfen 041000 , China) Abstract :This article mainly introduces production and applction of the high chrome cast iron austenitic grinding ball. For obtaining austenite in casting state , the balls have stronger impact toughness. In addition, martensite transformation happens under impact wear […]
Since April 1, 2001, when the cement mill gave up the use of low-chromium alloy cast ball to replace the use of high-chromium Alloy cast ball, two months after the cement’s normal operation mill under suitable technological conditions. On June 1, 2001, the test was carried out by Fengjiang Cement Research Center. The test results […]
