Dry Granulation Machine

Dry granulation machine adopts a granulation method which doesn’t need to add binder or water when granulating. What’s more, you don’t need to dry the finished pellets by drying machine. This method takes advantages of the crystal water of the raw materials, shaping them by strong extrusion. The dry granulation equipment integrates compressing, crushing and granulating. To some extent, this machine makes up for the deficiency of the wet granulation method in raw materials requirements and granulating process.

What is dry granulation process?

Dry granulation machine adopts the dry granulation process to make fertilizers granular. It is applicable for forming granules without liquid solutions, because the granules may be sensitive to the moisture or heat. And it shapes the granules by press the materials. You can use double roller press machine to produce fertilizers by dry granulation. The counter-rotating rollers provide strong extrusion force for pressing materials into large tablets. And the inner structure of machine will crush these tablets and make them into pellets.

Where does the dry granulation machine make up the deficiency of wet granulator?

On the raw materials requirements processing

  • You can use the raw materials which can not mix with water, or the materials which will change its particle structure when drying. These materials are not suitable for wet granulation method. However, the dry granulation facility can granulate them into pellets.

On the power consumption

  • It can save your power consumption. The double roller granulator machine employs no-drying process. You don’t need to equip with drying machine. It will save your power consumption. What’ more, it works at normal temperature, which saves the the fuels consumption. By contrast, the wet granulation granulation facility needs to dry finished pellets for dehydrating, increasing the power consumption.
  • It can save your labour consumption. The dry granulation equipment is easy to operate, and the granulating process is simple, too. You can arrange less labor to operate it than wet granulation machine.
  • It can save your binders consumption. Different materials need to add different binders, you should use many types of binders for granulating by wet granulation process. However, the dry granulation facilities utilize the crystal water of materials, shaping them by mechanical extrusion and crushing them without binders. This dry granulation method eliminate the binders consumption.

On the environment protection

  • Dry granulation process has no gas emission and waste water during the granulating. And it produces less waste water when cleaning because of its simple structure. While the wet granulation method must equip with drying machine, which consumes lots of fuels and causes pollution. Moreover, the binders may stick on the machines which may produce more waste water when cleaning.

Tongda has double roller granulator to meet your dry granulation production requirement

Roller press granulator play a key role in compound fertilizer production line and it is also a typical representative of dry granulation facilities. It is applicable for high, medium and low concentration of special compound fertilizer. Its dry granulation process can bring you high economic efficiency because of its low consumption, whether on the power or the labour force. What’s more, you can choose the shapes of the finished pellets, because there are many grooves on the roller sheets, the shapes of grooves decide the pellets shape. And Tongda fertilisers equipment manufacturing factory can customize the grooves shapes on the roller sheets, also the materials of roller sheets. For dry granulation production, the double roller fertilizer granulator will be your best choice.

What’s the dry granulation steps?

Preparation of materials

  • The raw materials for dry granulation must contain crystal water or the moisture content is about 5%. You’d better use the 80 mesh to 300 mesh materials for granulating. If it is too crude, the finished pellets may be unevenly. As for the fine powder, it is difficult to granulate. Thus, you should prepare suitable raw materials for dry granulation.

Feeding uniformly

  • When you feed materials into the dry granulation machines, keep feeding uniformly. The roller sheets are easily damaged parts. Feeding uniformly may prolong the service life of the roller sheets, and also contribute to improve the granulation rate.


  • The counter-rotating roller sheets will press the materials into large tablets with strong extrusion force.
  • Then the inner structure of machine will crush the tablets and granulate.
  • Finally, the finished pellets will get out from the outlets.

Advantages of facilitating a dry granulation machine for your industry

This dry granulation equipment has great effects on many fields, especially for pharmacy and fertilizer production.

  • It can make the raw materials into specific shapes. You can choose the grooves shapes on roller sheets to make specific pellets shapes including pillow shape,stick shape,pill shape, walnut shape, flat ball shape and square bar shape.
  • It can avoid the agglomerations in granulating because of no binders. Besides, it is applicable for making with materials which couldn’t mix with liquid solutions particularly.
  • It can decrease the drying process and cooling process. The pellets made by dry granulation equipment can be dried by air.
  • It decreases the dangerousness of toxic and corrosive materials during the processing.
  • The granules made by it are more convenient for storing and transporting. Turing powder into fertilizer granular increase the volume mass of powder materials, and make them convenient for storing and transporting.
