3T/H Capacity Carbon Steel Double Roller Granulator for Dry Granulation Compound Fertilizer Production

The compound fertilizer granulator 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 machine is continuous extruding granulation of positive-displacement.

• The compound fertilizer granulator belongs to dry granulation. It is not necessary to adjust the dryness and humidity of the material during the granulation process, and there is no need to increase the drying equipment.
• Compound fertilizer granulators can be used to process granules containing heat-sensitive materials.
• Because it is dry granulation, no waste water or waste gas will be emitted during the production process.
• The compound fertilizer granulator has simple process, easy automatic control, and high production efficiency.
• The flexibility of the roller extrusion compound fertilizer granulator is good, and the fertilizer production plan can be unaffected at any time.
• The uniformity of the particle size of the roller extrusion granulation is a significant advantage, because the ball socket size of the roller is the same.

The compound fertilizer granulator has wide adaptability of raw materials including DAP, SSP, GYPSUM, SHEEP MANURE, COW MANURE, chicken manure, pig manure, bentonite and other animal poultry manure waste. The roller press granulator production rate is high.

It can produce all kinds of high concentration with various fertilizers including organic fertilizer, inorganic fertilizer, compound fertilizer, etc. especially rare earth fertilizer, potash fertilizer, ammonium bicarbonate series for this fertilizer double roller 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.
