DG series Powder Double Roller Granulator

Dg series double roller granulaor adopts no-drying process granulating at normal temperature and once forming.

 DH series dry roll press granulator adopts dry rolling technology to compress the powdery materials with moisture content ≤ 5% into pieces or tablets, then going through the processes of breaking into pellets and screening to make the lump materials into pellet materials that meet the requirements of application. Dry roll press granulator mainly depends on the manner of external pressure to force the material going through the clearance between the two relatively turning rolls to compress into laminar particles. During course of roller pressing, the real density of the materials can increase 1.5-3 times thus reaching certain demands to pellet strength.

Product—Screen-Undersize-Fresh Feed-Roller press- Overflow---Crusher

Solids in the gap between two counter-rotating smooth or profiled rollers.

The produced material ribbon, called sheet, is an inter mediate product from which the final granular product is produced by crushing and screening processes.

This process is used for reducing dust emissions, improving the metering characteristics of components, and avoiding segregation problems.

Compaction is nearly always carried out without using binding agents.

The compaction process is traditionally used for the production of fertilizers in the form of single-component fertilizers(e.g.KCL) or mixed (NPK) fertilizers.

The technology also covers many applications in the chemical industy.

The granulate production capacity depends on product grain size and the machine types selected foe subsequent crushing and screening. For the most common applications the product yield is between 25 and 50%.
