Dry granulation is used in double roller granulator
The new double roller granulator produced by our company adopts dry extrusion technology. On the basis of the original single shaft to roll extrusion granulator, through continuous improvement and practice research and development, the extrusion force of this machine is far greater than that of the previous single shaft type; in particular, ammonium chloride, ammonium sulfate, snow melting agent, ammonium bicarbonate, potassium fertilizer, industrial salt series granulation rate is high More than 85%, high strength and good molding.

Equipment flow of double roller granulator fertilizer production line
Automatic batching system → fertilizer mixer machine → double roller granulator→ screening machine → packaging machine
The characteristics of the double roller granulator are as follows:
1. No drying process, normal temperature granulation, one-time molding, less investment, quick effect, and good economic benefit.
2. Small power of double roller granulator, reliable operation, no three waste discharge, stable operation, convenient maintenance, reasonable process layout, advanced technology, and low production cost.
3. The raw materials have wide applicability, and can be used for granulation of compound fertilizers, and can produce compound fertilizers of various concentrations and types (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetized fertilizer, etc.); there are also rare-earth, ammonium bicarbonate, and ammonium sulfate compound fertilizers granulation.
Instructions for double roller granulator:
1. The double roller granulator should be started without load, and it is strictly forbidden to start with material.
2. It is strictly forbidden to enter the material with dirt in order to avoid breaking the roller shaft.
3. The gear of the fertilizer granulator machine should be smeared with yellow dry oil before starting up.
4. Apply yellow oil to the chain and sprocket every 7 days.
5. The bearing pedestal shall be filled or replaced with new yellow oil every three months.
6. The gear oil can be used only after adding gear oil once before use. The gear oil should be changed every four months.
