double roller granulator is multifunctional fertilizer press machine, this fertilizer roller press granulator can make compound fertilizer but also can make organic fertilizer granules.it is multifunctional,but the finished granules are oval shapes. you can use a ball shaping machine to make it into round granules, Which is developed by our own company. Production process only needs room temperature without drying machine, which can save a lot of energy and cost, the double roller press granulator production yield is 0.5-1t / h,1-1.5t / h,and 1.5-2t/h. if you want to use disc granulator,that is also best machine for organic fertilizers.
Advantages of roller press granulator
1.the roller press granulator has less investment, good economic returns.
2.complete set of fertilizer extrusion granulator is compact, scientific, reasonable and advanced technologies.
3.No waste discharge,stable,and easy operation and maintenance.
4.this roller extrusion granulator can directly squeeze dry powder materials into granules,which belongs to dry method granulation
Application of double roller granulator
The roller extrusion granulator has wide adaptability of raw materials is DAP,SSP,GYPSUM,SHEEP MANURE, COW MANURE , chicken manure, pig manure,bentonite and other animal poultry manure waste and so on.the roller press granulator production rate is high.
It can produce all kinds of high concentration with a various fertilizers including organic fertilizer, Inorganic fertilizer,compound fertilizer,etc.especially rare earth fertilizer,potash fertilizer,ammonium bicarbonate series for this fertilizer double roller compation granulator.the fertilizer press machine makes up the gap leading the position in domestic.when using this granulator as a whole fertilizer production line,it does not need a rotary dryer.
The double roller compaction granulation machine is the representative of extrusion granulator. Dry materials are compressed into hard & dense blocks at a pressure, which is the Extruding Process. Block materials are crushed, screened and granulated later, which is the Granulating Process. The functions of extrusion are to squeeze the air between particles out, and to make the distance between particles near enough to give rise to interaction forces. The particle hardness of roller compaction granulation granules is formed mainly due to attraction between the molecules.
Our double roller press granulator machine is continuous extruding granulation of positive-displacement.this double roller press granulator has two main working parts:1.squeezing and pressing part: materials are pressed into big high density and hard cake,under the squeezing pressure.2.granulating part:the press cake is crushed and screened into small granules.

Remark:finished granules by this double roller compaction granulation machine is oval shape, if you want round ball shape granules,a ball shaping machine can help, ball shaping machine is used to make cylindrical and oval shape granules (pellets) into round ball shape granules.it adopts high speed rotation working principle to make round ball pellets.
