A.1  Under the following normal operating conditions, the ball broken rate and wear rate of the ball mill running for 2000h and 3000h are shown in Table A. 1.

Forno de têmpera

Continuous tempering furnace is to heat treating the ferrous metal product, so as the casting grinding media balls. Casting grinding media balls are now widely used in cement, mines, thermal power station, and construction works. But the qualified grinding balls, especially for high chrome grinding balls, need to do the not only the quenching but […]

Processo de fabricação de meios de moagem

A mídia de moagem é amplamente usada em minas metalúrgicas, materiais de construção de cimento, geração de energia térmica, dessulfurização de gases de combustão e outras indústrias de moinho de bolas. Mas qual é o processo de fabricação da mídia de moagem? Explicaremos aqui claramente. (Aqui falamos principalmente sobre a mídia de moagem de fundição.)

Linha de moldagem de meios de moagem

Automatic grinding media molding line is widely used to produce alloyed grinding media balls for different types and sizes. It adopts metal iron  mold which can realize the chilling process to make the balls’ grains refining.
