Franli three roll mill related introduction and why choose it

Three horizontal rollers have different materials of roller. The most roller is alloyed for universal chemical materials. We also offer Zirconia 95% for cosmetics, un-polluted material. While granite roller is used for a crayon. Crayon needs heating, cant be polluted. Other chemicals such as leathers, color masterbatch should be heated milling.


Hydraulic three roll mill

Hydraulic three roll mill


Three roll mill has two types, one is a hydraulic three roll mill, another one is a manual three roll mill. How to choose? which depends on your production capacity per day, and the final particle size of the material.  Manual three roll mill can reach around 5-10um, hydraulic three roll mill can reach 3um. You may already bring three roll mills but can't reach the ideal particle size. Why? different color has difference feature of raw material.  Such as material with carbon black, you may need grinding 3-4times to reach 3um. If you grinding white or yellow colors, max 2 times grinding to reach ideal size.

Three roll mill can connect with heating oil system, steam heating system. Also cooling water by Chiller. While you may have one question that your machine cant control temperature by the chiller, the roller is heated.  How to check? First, you need to check the inlet water filter of three roll mill, impurity blocked filter, colled water cant inlet into the roller of three roll mill.  Also, you may need to check chiller problems.  In our experience, you would better choose an opening type of cooling system, joint rota connection system will be damaged by shaking and not so well for cooling.

What are the Advantages of three roll mill

Some high viscosity materials or no-flowing materials need smaller particles size than the final material. Then have to choose three roll mill. Three roll mill is still a key machine in the market, which is an unreplaceable machine in process of some material. 

What is the Purpose of three roll mill

You may ask what us purpose of three roll mill, which is a very clear purpose.  We would like to produce three roll mill for your more smoothy and smaller fineness material.  Some materials are more fitness, smaller sizes. Which material will be more popular in the market. Got more valuable material.
