Searching for a three roll mill? Have a look here!
A three roll mill is a dispersing device used to blend, refine, disperse and make highly viscous materials uniform. It is extensively used in chemical industries to mix cosmetics, paints, printing inks, ceramics, and much more.
What is a three roll mill?
This might be a question on your mind, that why does a three roll mill use shear forces for dispersion? The answer is simple, let us understand it with the example of a traditional agitator. An agitator has a common issue of accumulation of small particles. The use of unaligned forces prevents accumulation by breaking apart even very tiny particles.
The purpose is simply as much reduction as possible. The reducing ability of a three roll mill can even be as low as 1 micron.

Why a three roll mill is better than any other kind of roller mill?
A single-roll mill has a roll and a secure bar thrusting against the roll. The material keeps passing between the two until dispersion, which usually is a very slow process.
A five-roll mill has four smaller nips and hence the particles in the input material can be larger as compared to a three roll mill but this mill is larger, much more expensive, and difficult to handle.
After taking a look at the other types of mills, it is rather obvious why people prefer a three roll mill.

How does a three roll mill work?
A three roll mill consists of three heavy wheels placed horizontally and rotating along their axis to compress different materials. One of the three rollers are run by the use of a motor, the others run due to the friction created between the gaps of the rollers, as the material is drawn towards them.

The size, shape, and form of the result largely depend on the following factors:
· The gap between each of the rollers.
· The difference in speed of both the rollers.
To be able to get the desired results, one needs to take keep these factors in mind and adjust them according to their requirements.

The right way of maintaining a roller mill
Certain things must be done to maintain the condition of a three roll mill. The following is the list of things one must not ignore after purchasing a mill:
· Regular oiling is a must. It is recommended you oil the machine at least once every month.
· The turbine box must be filled with grease regularly.
· The correct maintenance of the hydraulic tank is very important.
· The cleaning of the oil filter is very important and is needed to be done frequently, otherwise, the filter can jam and the hydraulic pressure might get decreased.

· Despite the high amount of compression work being done, the mill produces very little heat, hence keeping the temperature low.
· The rate of loss of moisture in this mill is tremendously low.
· The noises created by the machine are extremely low and so it helps in making the work environment and the environment in general, better.
· It is efficient and saves a lot of energy.
· The dust generation through the input material is also very which is the work environment is not hazardous.
