There are many types and varieties of ceramic grinding media products, both within the Keramos product portfolio, and from differing manufacturers and suppliers. Differing media types have differing physical properties as well as performance properties, the effect of media type selection on comminution process performance can be extremely significant. Affecting; Media performance, consumption / grinding efficiency, and Mill / Process performance; mill power draw / process capacity / mill wear.

The UFG Metallurgical Laboratory Keramos provides detailed studies investigating the optimisation of ceramic grinding media product selection relevant to customers specific milling technologies / duties and ore types. Comparative studies can produce data to assess the performance of differing ceramic grinding media products according to the following factors:

• ECONOMIC EVAUATION OF MEDIA CONSUMPTION
– Test outputs = energy specific wear rates (g/kWhr)
– Scalable to Industry
– Controlled and accurate comparisons

• OPTIMISING APPLICATION SPECIFIC MILL OPERATING PARAMETERS
– Mill power draw with respect to customers process constraints
– Minimising machine wear

• OPTIMISING APPLICATION SPECIFIC COMMINUTION PROCESS PARAMETERS
– Aligning media selection with process capacity demands
– Grinding efficiency

Keramos can provide these services in the following approved laboratory and pilot technologies:
OUTOTEC HIGMILL – GLENCORE XSTRATA ISAMILL – STIRRED MEDIA DETRITOR (SMD)

“Keramos has saved us around AUD$2 million per year directly on media costs. The other savings are mill linings, agitator arms, maintenance costs, downtime, freight and storage. Consequently, we’ve awarded Keramos a long-term contract for the supply of their ceramic grinding media.” –
