A pellet press (granulator) is the main device in a production line. It is responsible for the proper compaction of the previously prepared raw material and giving it the proper form (pellets). If you are considering purchasing a pellet press, read this post.
Granulator with a moving die or moving rollers?
The first step in choosing the right pellet press should be a decision regarding what types of raw materials are to be processed in it. Some machines are designed for soft raw materials such as straw or hay. Others work better for processing harder materials, for example, sawdust from coniferous and deciduous trees, fertilizers, and mineral raw materials. Improperly matching the device to the material being processed can cause faster wear of the dies and rollers, and even lead to a serious breakdown of the granulator. Selecting the right press also has a huge impact on the quality and physicochemical properties of the final product.
In some granulator models, the main shaft drives the die, while in others, it drives the rollers. Granulators with a moving die are characterized by higher efficiency; however, they may cause problems when processing hard raw materials in continuous mode, causing the material to hang up. Therefore, granulators with moving rollers are better suited for sawdust and other hard materials.
How to choose the granulator efficiency?
An important feature of a granulating press is its efficiency. For large, professional enterprises whose main branch of economic activity is pellet production, pellet mills with an efficiency of 650 kg/h and above are recommended. The parameters of the granulator should be matched to the parameters of other machines and equipment included in the technological line for pellet production. Otherwise, some of them may hinder the work of others, causing disturbances in their operation and production downtime. Before a planned investment, it is always worth carefully familiarizing yourself with the options available on the market. We also recommend using offers from professional manufacturers and distributors for such large investments.
