Grinding Media Balls, mill balls for ball mill, including casting balls and forged steel balls, tell you the difference and how to select.
On the one hand, the addition of chromium in casting grinding ball decreases the carbon content of the eutectic point and decreases the austenite area in the phase diagram. On the other hand, the type of carbide structure changes from reticulate M3C type to isolated M7C3 type, and the hardness of carbide increases, from 850 […]
The high chromium cast iron products treated in this paper are made of hot metal with a temperature of 1550 °C, which are cast into 80mm diameter high chromium cast iron grinding balls in a cold mould. The chemical composition of the material is shown in Table 1.
Abstract: Fe-2.4C-12Cr high chrome white cast iron balls with a diameter of 80mm was quenched and tempered with water and air by MQ-P-T method, analysis of mechanical properties and microstructure, weaving, alignment, comparison. The strengthening and toughening mechanism of MQ-P-T treated high chromium cast iron was investigated using micro-and microstructure characterization. The results show that […]
According to the designed composition, the molten iron is smelted by induction furnace; after slag removal, temperature adjustment, alloy addition, sampling analysis, and adjusting the composition to be qualified, the molten iron is drawn out at 1500 ~ 1550 °C and is modified by the inner-ladle method, at 1400 ~ 1450 °C, Molten iron is […]
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.
