So, you must ensure that you select the right media size.

We will share some tips which can help you to select zirconium silicate beads of the right size.


5.1 Life of the Media

The media life is a critical parameter.

You must ensure that you can use the selected media size for many years without any breakage or deformation.

If you go with the smaller media, then life will be less.

The smaller media is more prone to breakage than the larger one.

So, choose wisely.


5.2 Separation of the media

You should be able to separate the media from the parts easily at the end of the process.

So, the media size must be different from the part size.

You will be using a separation method to do this job.

So, ensure that the size matches the separation method.


5.3 Size of the part

The size of the material needs to be considered first.

The media must be able to reach all the area in the part for an efficient grinding process.

If the part has holes or crevices, then ensure that the media does not get stuck in these holes.

Here, a small size media will be more useful as it can reach more surface area for grinding.

It will help to increase the grinding efficiency of the process.

If you still find it hard to select the right media size, then check with our engineers.

They will help you to select the right size based on your milling requirements.


6. What Is The Typical Lifespan Of Zirconium Silicate Media?

So, life will be more if you use it for parts that require less grinding time.


7. How To Use The Zirconium Silicate Balls In A Grinding Machine?

If you use the zirconium silicate beads in the right way inside the milling machine, then you can make the process efficient and cost-effective.

Firstly, you need to ensure that the grinding chamber is neat and clean.

The zirconium silicate beads must undergo a visual inspection before putting it into the chamber.

It is done to ensure that there are no broken media balls.

Check and ensure that there are no blocks in any of the outgoing pipes of the machine.

Use the appropriate resin and solvents to pre-grind the media in the chamber.

The pre-grinding must be done for a predefined time.

The viscosity of the slurry determines the pre-grinding time.

If the viscosity is low, then the pre-grinding time can be less.

For a more viscos slurry, higher pre-grinding time is recommended.

The next parameter to set is the rotational speed.

The rotation speed is also dependent on the slurry viscosity.

It is directly proportional to the slurry viscosity.

The rotational speed will be high for a highly viscous slurry and vice versa.

You must load the chamber with parts and media in the recommended ratio.

If it is a wet grinding process, then you can run the machine at lower speeds.

Once the processing is complete, you must separate the media from the parts.

The processing time will vary for different applications.

The media must be washed and cleaned properly before storage.

Check the media for any damages.

If any, please remove the broken parts.


8. What Are The Different Ways By Which We Can Increase The Life of Zirconium Silicate Media?

There are many factors that affect the life of the zirconium silicate beads.

The factors are listed below.


8.1 Media Stress

Stress is a great factor that affects media size.

Higher the media stress, lesser will be the media life.

So, try not to run the media for grinding continuously for a very long time.

It will put the media under more stress.


8.2 The Right Media to Part Ratio

Most customers tend to use a lower media ratio than the recommended thinking that they can process more materials.

But it will do more damage than good.

The media life will come down if you use a lower ratio than the recommended value.

So, always ensure that you maintain the right part to media ratio inside the chamber during the grinding process.

When there is fewer media in the chamber then parts will come in contact and there is a chance that the parts may get damaged during the rotation.

The finish on the parts will not be uniform.


8.3 Always Buy High-Quality Media

You may be able to get zirconium silicate beads for half the standard price.

But these media will be made from very poor quality raw materials.

So, life will be very less and the media will be prone to wear and tear.

So, you will end up buying the media again.

The quality of the finish also will not be good.

So, always invest in high-quality media.

Inovatec machinery manufactures the best quality zirconium silicate beads.


8.4 Lowering the Heat Generated

When you grind the materials with the media inside the chamber, there will be some generation of heat.

This heat will be more if it is a dry grinding process.

In such cases, try to make some set up to lower the temperature inside the chamber whenever excess heat is generated.

In the case of the wet grinding process, water or any other liquid can be used to reduce the temperature.


8.5 Storing the Media

It is best to wash and clean the media before storing it.

So, try to do it regularly after each use.


8.6 Larger Media Size

The size of the media is an important factor that affects media life.

Large size media is less prone to tear and wear when compared to small size media.

So, life will be more for the large size media.

So, if you can execute an efficient grinding/ milling/ dispersion process using a large size media, we would recommend you to go with one.

So, small size zirconium silicate beads can finish the grinding process faster than the large size ones.

So, the processing time will be less for the small size media balls.

Thus, the grinding efficiency is more.

The life of the small size media is less than the bigger ones.

So, you need to make a trade-off here.


10.2 Timely Replacement of the Media

Some of the media balls may get broken if the grinding process is run for a long time.

So, you need to do a regular inspection of the media state during the process.

If you find any deformed or broken media pieces, then you must stop the process and replace the broken ones immediately.

Broken media will impact the efficiency of the grinding process.

So, immediate action will ensure that the process efficiency is not compromised.

Your broken media removal procedure must not take too much time.


10.3 Temperature Control

The grinding of the parts with the zirconium silicate beads will result in the generation of lots of heat inside the chamber.

This can affect the efficiency of the whole process.

So, you must have proper methods to remove the heat generated during the process.

If it is a wet grinding process, then the water or the solvent can be used to remove the excess heat.

For a dry grinding process, the chamber must have some sort of temperature controller to lower the temperature.


10.4 Regular Maintenance of the Machine

There is a chance that the milling machine gets break down during operation if you don’t do the regular service and maintenance activities.

So, make sure that the maintenance activities happen regularly without fail.

If any part needs a replacement, then replace it as early as possible.


10.5 Machine Load

The load in the machine is another critical parameter that will have a direct impact in the efficiency of the whole process.

Don’t operate the machine above the recommended load.

If you overload the machine then the machine life will come down, media life will get reduced and you will not get the desired quality finish on the material.

It is also not a good habit to run the machine at low loads.

So, make sure that the load capacity is at least 60 percent.

For a highly efficient process, the load capacity must be in the range of 80 to 90 percent.

These values may change with the type of the machine.

So, check the operating manual of the machine to know the load recommendation values.


10.6 Zirconium silicate bead Quality

Bigger ones will take more time to complete the grinding process.


11.2 Rotational Speed

Speed of rotation is another factor that impacts the grinding time.

Higher speed will make the processing faster.

But you must also check the operators recommended operating conditions to ensure that you run the machine in the safe operating limits.


11.3 Slurry Viscosity

The viscosity of the slurry is also taken into account.

If the viscosity is more, then the frictional force will be more between the media and the materials.

Higher viscosity also allows you to increase the rotational speed of the chamber.

If the viscosity is low then the friction will be less and the grinding time will be more


11.4 Load capacity of the machine

The machine load capacity is another factor.

If the machine comes with a higher load capacity then you can process more parts at the same time.


11.5 Material Finish Requirement

The final finish of the material will also affect the processing time.

If the final finish of the part is glossy, then you need to run the machine for more time.

So, the processing time will be more.
