The Most Widely Used Grinding Medium

——Steel Ball

  • Steel ball, as the indispensable consumable to ball mill, is a kind of wear-resistant material that made of carbon, chromium, manganese, and molybdenum, etc. as the main added metal elements, and can be produced through forging, spinning, rolling, grinding and casting.

Xinhai High Quality Steel Ball to Improve Your Grinding Efficiency and Reduce Grinding Cost

Grinding Cost Analysis

  • Based on a relevant data analysis, steel ball has great influence on cost and performance of grinding, and takes 8 % on the mill plant overall operating costs, and 30% on the whole grinding cost, thus steel ball affects a lot to the total grinding operation, efficiency and operating cost. Choosing the proper steel ball to reduce the loss is an important way to improve the efficiency of mill plant.

  • Energy Consumption
  • Grinding Medium
  • Personnel and Others

Dangers to Use Inferior Steel Ball

  • Inferior steel ball can easily crack and spalling, which can shorten the service life of the slurry pump, hydrocyclone, and the cycle load line.
  • Steel Ball Scraps distribute to increase the ball mill load and the energy consumption.
