7. How To Select The Right Zirconia Bead Size?

The right size of zirconia media will help to make your process more efficient and cost effective.

Large size media will have more life than small size one. But that does not mean that you need to choose the largest possible size.

The size must be selected in such a way that it matches with the size of the parts or elements under processing.

If the particle size is large, then go for a large media size. It will help to break up the particles effectively.

Most of the conventional mills make use of large size medias.

Attritors commonly use small size zirconia beads.

Media size of 5mm is mostly used in many of the attrition mill applications.

15mm zirconia balls are used in lab mall mills.

You need to also consider the gap between the mill walls and stirring arms while selecting the zirconia bead size.

The size of this gap must be larger than the bead size to prevent any sort of jamming.


8. How To Use The Zirconia Beads Inside The Mill Chamber?

First, you need to ensure that you are using the zirconia beads of the right size.

The mill must be properly cleaned before loading the beads into it.

Ensure that the outlet of the machine does not have any kind of blocks.

The speed of rotation must be set to an appropriate value.

Pre-grinding is recommended before starting the actual process.

You can run it along with the resin and solvent mix for around 30 minutes.

The viscosity of the slurry is an important factor in deciding the rotational speed of operation.

If the viscosity is low then you need to run the pre-grinding process only for half the time.

The speed of rotation also must be kept low for a low viscous slurry.

If it is solid content, then you don’t have to run it at very high speeds.

The beads will have sufficient kinetic energy to do the grinding process efficiently.

You must use resin for cleaning the beads if you are looking to grind paint.

Sometimes solvent needs to be added for cleaning purpose.

In such situations, you need to run the process at lower speeds and the beads must be cleaned immediately after the process.

If you are using small beads for a prolonged process, then there is a chance that some of the beads may get broken during the process.

In such cases, you need to remove the broken ones and replace it with zirconia beads of the same size and weight.

The processing time will vary for different parts.

It is because the finish requirement will be different for various materials and applications.

11. What Are The Different Ways To Increase The Efficiency Of Milling/Grinding Process Using Zirconia Beads?


You must always ensure that the grinding process is run in an efficient manner.

It will ensure that you can reap more profits from your business.


11.1 Cooling system

The grinding process with zirconia beads will result in the production of heat inside the chamber due to high dense media.

This high heat will impact the efficiency of the process.

It can even damage the materials.

So, it is recommended to use a proper cooling system for the chamber to ensure that heat generated gets nullified.


11.2 Size Factor

Bead size is another important factor that affects the efficiency of the process.

Smaller bead size will get in contact with more area, as a result, the overall grinding time will get reduced.

So, the efficiency will be more.

But, the life of the smaller bead will be less when compared to the bigger one.

So, a trade-off should be done.


11.3 Chamber Capacity Vs Load

The capacity of the chamber is another factor.

You must not load the chamber more than 85 percents of the rated load capacity.

For maximum efficiency, ensure that the load is not less than 60 percents.


11.4 Avoid Bead Deformation/Breakage

The gap between the agitator arm of the mill and the walls and bottom of the chamber must be at least 3 times larger than the bead size.

It will ensure that the zirconia ball will not get broken or deformed during the grinding process.


11.5 Strainer Aperture Size

The zirconia beads in the mixture must not pass through the strainer.

In order to ensure a smooth and efficient process, the zirconia bead size must be at least two times larger than the aperture size of the strainer.

So, make use of these tips to increase the efficiency of your milling process with zirconia beads.


11.6 Bead Quality Check

It is a good practice to check the quality of the zirconia media before lading into the milling machine.

You can inspect and ensure that the beads are not broken or in a deformed state.

Visual inspection would be sufficient to do this check.

If you find such beads, then remove them and load the chamber only with beads in the right shape and size.

The same check can be applied for the beads after the process, before storing them.


11.7 Follow the Milling Machine Manual

We recommend following the operating instructions provided in the respective milling machine manual.

It will ensure a smooth and efficient process.

Also, do the necessary maintenance works without fail at regular intervals for the machine.
