Advantages of Flat Die Pellet Mills:

Generally, there are two main merits of flat die pellet mill. Firstly, compact structure. As we all know, flat die pelleting machines always refer to small pellet mills which means they are small in size and have the character of light, convenient to be moved and easy to be cleaned as well. The other advantage is its visibility. Many flat die pellet mills today are possible to view into the chamber when pelletizing, so you can solve and correct any problem quickly by easily viewing what has happened inside the chamber, that is also to say the flat die design has much more wider material choice. 
As to the disadvantage, the greatest one is the wear and tear during the pelletizing process. Rollers’ inner and outer edges covers different distances when rollers rotating across the surface of die. However, pellet mill manufacturers have improved rollers to reduce the wear.
