No Drying Required Double Roller Extrusion Granulator Dry Granulation Machine with Adjustable Pellet Diameter 4-10mm and High Granulation Rate ≥85%

The double roller extrusion granulator adopts a no-drying granulation process, realizing normal-temperature one-time forming for dry powder materials. It does not require extra drying equipment, which greatly cuts the whole production investment and energy consumption. The finished pellets feature high granulation rate and strong compressive strength.

With compact structure and stable operation, this machine delivers fast returns and good economic benefits. It is widely used for granulation in fertilizer, feed and chemical industries. It can process dry powder materials with low moisture of 2%–5% and produce oblate pellets with adjustable diameter from 4 mm to 10 mm. It is an ideal molding device for small and medium dry powder granulation projects.

• No drying required — normal temperature granulation with one-step forming, saving drying costs
• High granulation rate ≥85%, finished pellets with high compressive strength of 6–20 N, not easy to break
• Suitable for low-moisture dry powder raw materials (only 2%–5% moisture required)
• Compact layout, low total investment, quick payback and good economic benefit
• Adjustable pellet size from 4 mm to 10 mm, oblate pellet shape
• Stable running, low failure rate, easy operation and maintenance
• Wide raw material compatibility for fertilizer, chemical and feed powder materials

This double roller extrusion granulator is widely applied in fertilizer, animal feed and chemical industries. It works for organic fertilizer, compound fertilizer, ammonium sulfate, humic acid, bentonite, graphite powder, snow melting agent, carbon additive, talcum powder, white carbon black, mineral powder, catalyst, pesticide powder and other dry powder materials. It fits small and medium production lines that need dry granulation without a drying process.

This machine works on the dry roll compaction extrusion principle. Dry powder raw materials with moisture of 2%–5% are fed evenly between a pair of synchronous rotating rollers. Under the squeezing force of the two rollers, the powder materials are compressed and extruded into oblate pellets through the mold grooves on the roller surface.
