The advantage of the three roll mill instead of ball mill
Are you still using the ball mill process? It’s time to try out the three-roll mill.
It has been proved that in some applications, a Three Roll Mill can effectively replace the traditional ball milling process. Besides, it can also offer a great level of improvement in the overall throughput rate. What’s more? You will witness less amount of energy consumption and better production yield.
The three roll mill has emerged as an effective grinding as well as dispersing equipment to process high viscosity materials. As a result, the machine is widely used for grinding different types of liquid paste and paint materials, for example, plastics, pigments, inks, paints, rubber, ceramics, cosmetics, and more.
Some common issues that you can face while using the ball milling process
Well, there is no doubt that ball milling machines are quite easy to operate, and they are very versatile. In fact, some designs can be used for wet and dry feeds. However, the machines come with multiple drawbacks. For example, it performs a little slower than other milling machines. As a result, the throughput will be a little low. Besides, you may also deal with issues like clogging, higher energy consumption levels, and more. Furthermore, the machines are not easy to clean.
So, do you want to optimize the material milling process? Well, you can always go for a Three Roll Mill. Even though not all the applications that you can perform using a ball mill can be carried out by the three-roll milling, but this is perfect for slurries or pastes having moderate viscosity.
Understanding the theory of operation
Thanks to the adhesion. As the rollers move in a different direction, they create a perfect grinding action. In this machine, the rotational speed will gradually increase sequentially from one roller to another. The shear forces will develop dispersion. You can reduce the distance between the rollers to witness a huge shear, but it can lower the throughput. Once the material is ground or milled, it is scraped from the apron roller using a take-off knife.
In general, most of the roller material of the three roll mill is carefully cast from alloy cast iron. On the other hand, the surface harness will be around HS70 degrees. The roller’s diameter is very precise as well as delicate. As per the experts, using a good quality machine, you can attain a grinding fineness of 15μm.
Is the product you are using three-roller mill material?
· You should always remember that the materials you want to use in the machine must have the right element of stickiness to them. As a result, the material will adhere to the roller surface perfectly and will transfer smoothly between the rollers. Before using the material, it is advisable to test it using a machine.
· Another thing you should remember is that a three-roll mill can’t handle powder or any solid material. It has been seen that some manufacturers add solvent to create a good level of wetness and make the material suitable for the machine.
Understanding a sample application
The advanced three roll mill comes with a hydraulic system that can control different parts, such as a pressure roller, discharging blade, two sides holders, and more. As a result, the system can boost up the production capacity compared to other milling processes. There is no need to go through any complex setup process, and you can enjoy higher production.

The ointment mills are largely used by the pharmaceutical industry, where color changes and smaller batches are needed. The mills use a strong shear force for dispersing active ingredients, and the ointment mill is popular due to its perfect cooling surface and temperature control.
The kneader for the dispersion process is supplied by the manufacturers offered uniformity in the compound that is being dispersed along with the fast washing of the product for the adjustment of color.
Sand mill is a kind of high-efficiency grinding equipment, which is mainly used for grinding materials, and the particle size of the final grinding can reach the nanometer level.
Horizontal sand mill is suitable for grinding and creating medium-viscosity liquid materials such as paints, inks, pigments and dyes, medicines, cosmetics, food, papermaking, electronic materials, etc. Horizontal sand mills are suitable for high viscosity, small fineness, volatile materials, and closed grinding.
Sand mill is an indispensable piece of equipment in the coating industry and chemical industries. It can not only be used to grind products with large particles, but also very fine products, which can reach the nanometer level at least.
Nano sand mill is a new type of grinding equipment, mainly used in carbon nanotubes, nanomaterial pigments, nanocoatings, inks, inkjet inks, cosmetics, food, proteins, lithium batteries, functional ceramics, photovoltaic materials, and other fields.
