Double Roller Extrusion Granulator for High Forming Rate Dry Granulation Process with One-Step Forming

The double roller extrusion granulator adopts a dry granulation process. It can complete normal-temperature granulation of dry powder materials and form pellets in one pass. It features high balling rate and strong pellet hardness.

With low investment and quick return, this machine is widely used for granulation in fertilizer, feed and chemical industries.

• Dry granulation at room temperature, no drying procedure required, save energy cost
• One-step forming, pelletizing rate ≥85%, finished pellets with good compressive strength
• Wide material adaptability, suitable for various dry powder raw materials
• Equipped with heavy-duty hard-tooth surface reducer for stable transmission
• Compact structure, small footprint, easy operation and maintenance
• Factory direct supply, on-site raw material test available, customized technical solution

Dry powder raw materials with proper moisture (2%-5%) are fed into the machine from the feeding inlet. Two counter-rotating rollers squeeze the powder under pressure, compressing powder into oblate pellets. Finished pellets are discharged from the outlet directly. No heating or drying needed during the whole production.

• Feeding Inlet: Feed dry powder raw materials evenly into the extrusion chamber
• Discharge Outlet: Discharge finished oblate pellets smoothly
• Hard-tooth Surface Reducer: Heavy load, stable running, long service life
• Extrusion Rollers: Wear-resistant roller mould, adjustable pellet size from 4-10mm
• Whole Machine Frame: Welded solid frame, low vibration during operation

• Organic & compound fertilizer production plant
• Chemical powder granulation workshop
• Feed processing factory
• Snow melting agent and mineral powder production line

Ammonium sulfate, graphite powder, bentonite, livestock manure, humic acid, silica powder, carbon raiser, snow melting agent, white carbon black, detergent, catalyst, talcum powder, monoammonium phosphate, diammonium phosphate, pesticide and other dry powder materials.
