What are forged steel balls?

Forged Steel Ball is a grinding media with superior surface quality, hardness, and impact resistance.

How are Steel Grinding Balls Manufactured?

Steel Grinding Balls are manufactured through the rigorous process of hot-rolling, forging, and stamping. The metal is heated up to 1050° C with super wear resistance material and then shaped into perfect spheres with heavy pressure machinery.

How to Choose Grinding Steel Balls?

The selection of grinding steel balls depends on the hardness and coarse particle size of the ore material. Harder material requires a steel ball of larger diameter for greater impact force.

How to Measure the Performance of Grinding Steel Balls?

The effectiveness of steel balls is determined by calculating the efficiency of the ball mill which considers multiple factors. The power per tonne of the ball mill is determined by the ball mill fill rate. Good Steel balls will have:

  • Greater hardness
  • Greater endurance and wear resistance
  • Smooth surface
  • The low circle loss rate
  • And low splintering rate.

 

The Grinding steel balls supplied by Camasteel go through full-scale industrial tests that ensure abrasion resistance and robustness of the media.

What is the Price of Grinding Steel Balls?

The price of steel balls for grinding depends on the diameter. On average,  8mm stainless steel balls cost around $6 per Kg, and 20mm steel balls cost around $1000 per tonne. For heavier media, companies usually only entertain bulk orders.

What are the Advantages of Using Grinding Steel Balls?

Grinding steel balls deal with materials too hard for cast iron balls. They are most robust, have better surface quality, and have higher abrasion resistance.

Steel balls are a recommended choice for heavy-duty and long-term work.

How Big are the Balls in a Ball Mill?

Ball mill performance is critically dependent on the ball size. Larger balls are effective for large-sized and hard particles while smaller balls are effective for the breakage of lighter and fine particles.

How to Calculate Grinding Media in Ball Mill?

Generally, steel balls must not fill more than 35% of the ball mill. The size selection of grinding balls can be calculated using the following formula:

Dm <= 6 (log dk) * d^0.5

Here, Dm = the diameter in mm of a single ball.

d = the diameter in mm of the biggest ore piece ore in the mill.
