Product Description
what is grinding ball?
Grinding balls are the media for grinding materials in ball mill equipment. The collision and friction between the steel balls of ball mills and materials produce grinding and peeling effects. Important basic components, especially precision industrial steel balls, play a huge role in the development of the national economy. effect. Widely used in cement plants, power plants, etc. High and low chromium multi-element alloy steel balls, high and low chromium multi-element alloy casting and forging.
1.Cast grinding ballCasting is a process in which smelted metal liquid is poured into a mold and cooled and solidified to obtain parts with the required shape and properties.According to the different chromium content, cast grinding balls can be divided into high chromium grinding balls, medium chromium grinding balls and low chromium grinding balls. High chromium grinding balls
High-chromium steel balls are typically defined by chromium content of 10% or higher. Our products boast a remarkable chromium content of up to 30%, endowing them with exceptional hardness and wear resistance. They excel in withstanding high-intensity grinding and crushing operations, demonstrating remarkable toughness to endure even the most powerful impact loads. Furthermore, they offer an extended lifespan and superior cost-effectiveness. With these qualities, our high-chromium steel balls prove to be the ideal choice for enduring performance and exceptional value in various applications.
Medium chromium grinding ballsMedium-chrome steel balls typically refer to steel balls containing chromium in the range of 3% to 10%. According to national standards, medium-chrome balls are required to have a hardness greater than or equal to 47 HRC (Rockwell hardness). To ensure quality, medium-chrome balls undergo high-temperature tempering treatment to eliminate casting stress.This tempering process is crucial for enhancing the performance and reliability of medium-chrome steel balls. By subjecting them to controlled heating and cooling cycles, we eliminate internal stresses, improve hardness, and enhance overall durability. As a result, our medium-chrome steel balls meet or exceed industry standards, making them a dependable choice for a wide range of applications where hardness, quality, and resilience are essential. Low chromium grinding balls
Low-chrome steel balls are defined as steel balls containing chromium levels of 3.0% or less, with carbon content ranging between 1.80% and 3.30%. These low-chrome steel balls serve as the vital grinding media in ball mills and find extensive applications in industries such as metallurgy, mining, cement, power generation, flue gas desulfurization, autoclaved aerated concrete production, magnetic materials, chemicals, coal-water slurry, pelletizing, slag, ultrafine powder production, fly ash, calcium carbonate, quartz sand, and more.Forged grinding ballForging is a metalworking process that utilizes forging machinery to apply pressure to metal billets, causing them to undergo plastic deformation and yield forged components with specific mechanical properties, shapes, and dimensions. Forged steel balls are distinguished by their low breakage rate, high impact toughness, overall hardness, resistance to deformation and out-of-roundness, as well as a dense microstructure. These attributes make forged steel balls a cost-effective choice, delivering significant cost savings. Their exceptional qualities ensure reliable performance, making them a preferred option across various applications in industries where durability and precision matterDetailed Photos
