High-performance micro-grinding media

A cost-effective solution
the advantages of using the highest-spec grinding media in grinding operations are well documented and well known. High density abrasives offer potential for increased production capacity, often significantly higher than the use of other traditional ceramic and glass abrasives. Improved toughness and resistance extend the life of the grinding beads and the maintenance cycle of the instrument.
is considered the best choice
stable zirconium oxide in the united States. The substance is an engineering grade ceramic with controlled zirconium oxide phase stability and extremely fine crystal size. The resulting grinding beads have better strength, fracture toughness and wear resistance.
the abrasive is more popular than other high-density abrasives because it is compatible with all equipment and wears less on the grinding part of the equipment, and, most importantly, its stable performance. This abrasive is particularly used in demanding and high-spec grinding, where accuracy, controllability and contamination are extremely important. However, it has not been widely adopted as a standard industrial product, mainly because of its high price and equally expensive grinding equipment.

in order to limit the cost of all media, people try different methods to control the level of processing. Reducing the degree of micro-powdering and sintering temperature is the main goal, but doing so often produces secondary products. One option is to replace stable ions (thorium oxide) with other oxides, such as magnesium oxide and zirconium dioxide. Some of these products have their own advantages, the resulting grinding beads have also found the right use. However, these grinding beads are definitely not comparable to high-performance, high-quality zirconium oxide stable zirconia grinding medium.
Zirmil Y
's development of a cost-effective, high-performance zirconium
oxide stable grinding bead has become a two-year focus of Saint-Gobain ZirPro
's central laboratory. Engineers at Saint-Gobansip have a good basis for this research. The company is one of the world's largest suppliers of zirconium
oxide and the founder of the introduction of ceramic micro-grinding media to the market
years ago.
the result of this program is the newly developed
- Zirmil Y
. By improving the ceramic formulation, this grinding medium retains the highest standards. This abrasive beads offer excellent density, thy size and size, as well as excellent wear resistance and service life. Figure

is the specific specification of this medium.
experiments have been carried out to ensure that the new substance achieves the desired high performance. There is a series of experiments that mainly compare the performance of the medium, known as "exaggerated wear test." A small horizontal grinder filled with standard
85
% of the grinding medium runs at high speed, plus only water. This is very demanding and accelerates media wear. Comparative data on similar-sized grinding beads are collected, and the results are listed in figure

.
from Figure

, it can be seen that
Zirmil Y
performs much better than the zirconium dioxide medium and is comparable to the known superior zirconium oxide stable zirconium oxide beads. This laboratory result has been confirmed by industrial testing and the medium provides excellent yield and grinding quality with low losses.
reduce the cost of operations
The performance of zirmil Y
has been confirmed and is satisfactory. The next important development of the new substance is the feasibility of its price, which, from a comprehensive economic point of view, will greatly enhance its performance and make wide use of the medium in most standard grinding applications. Figure

can be seen that the original use of the
Zirmil Y
much more than using traditional beads, but only slightly more expensive than beads. This is really an important change, previously, the price of zirconium oxide material has been considered to be two to three times the price of zirconium dioxide products. It is clear from the graph that, after a short period of time,
Zirmil Y
the advantages of operating costs continue to emerge. The material's excellent wear resistance reduces the need for fillers and extends the filling interval. Actual savings certainly depend on different applications and conditions, but
Zirmil Y
clearly shows its potential to significantly reduce operating costs. Importantly, the product plays an important role in reducing cost barriers and introducing this medium into large grinders.
conclusion
now, high-performance abrasives are widely used in industrial micro-grinding with real potential without the need to invest significant amounts of money in new instruments. Standard high-capacity grinders will adapt to this new medium and are likely to improve capacity and grinding quality. The price of the substance will soon meet cost-effective requirements, which will provide a long-term solution for initial fillers and efficient grinding operations.
