Grinding Media

Conventionally, grinding media was made of Cast iron, Cast steel and even through Forged process in EN specifications. However, High Chrome Grinding media has surpassed the conventionally produced grinding media in terms of performance and is now widely being used by all industries across the globe.

Ovalisation for New Balls

Definition of ovalisation ‘o’    :-     ‘o’ =    (Ø max – Ø min )      x 100

                                                               (Ø max + Ø min)/2

 

Technical Specification

The grinding media is manufactured by us in various specifications. The exact specification is suggested by us to the customer depending on various factors such as:

  • Material to be ground
  • Granulometry of the material
  • Grinding process (Wet/Dry)
  • Importance of wear mechanisms involved (abrasion, corrosion, impact).
  • Factors influencing the mill.

Mining Industries

Mining industries, because of the volume of ore to be ground, and the very large feed size, use 2 stage pulverising. In most cases, there is SAG mill, where primary grinding takes place, which used very large size grinding media, ranging from 80 mm to as high as 140 mm, and in secondary grinding, they use a ball mill, where ball sizes from 40 mm to 80 mm are used.

Such large consumption leads to a very sharp focus on consumption of grinding media. In fact in many mining companies, grinding media is the biggest consumable. Any reduction in wear rates leads to substamntial savings.

SBIPL has in the past guaranteed savings, in terms of wear rate, and achieved as much as 30 to 70% reduced consumption. SBIPL is supplying to various mining (and palletizing) companies in the country and in various places in continents of Africa, Asia, Australia, Europe and Americas.
