Classification Of Ball Mill Media Balls

Ball Mill Media Balls is an important basic component of ball mill and an indispensable accessory of ball mill. Under some special conditions, steel balls of special materials are often required to complete the functions required in different environments. Steel balls on the market are generally divided into two types: casting and forging, but their wear resistance is different.

Casting steel balls are used by steel ball manufacturers to heat up scrap steel, scrap iron and other waste charge in an intermediate frequency electric furnace to fully melt the charge. During the melting process of the charge, an appropriate amount of precious metal alloy is added to the furnace for chemical composition quenching and tempering. Wait for the molten iron After the temperature reaches above 1550℃ and the requirements of the process regulations are met, the qualified molten iron is poured into the steel ball mold or the steel ball production line mold. That is, the steel balls produced by casting and smelting are called cast steel balls.

Forged steel balls are steel balls manufactured by steel ball manufacturers through direct high-temperature heating and then forging. The chromium content of the forged steel ball is between 0.1% and 0.5%, and the carbon content is below 1.0%. If the permeability is poor, the hardness of the core is generally only more than 30 degrees. Under normal circumstances, water quenching is often used for forging steel balls.
