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 […]

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.

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%.

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 […]

The angle sensor is added to the equipment (pouring system on the balls production line), and the internal program is modified. First, the simulated pouring experiment with tap water is carried out, and then the trial production of hot metal is carried out. According to the observation on the spot and the data’s comparison, the […]
