Product Description
Ammonium sulfate 2-6mm granules twin rollers pellet mill
JIANGSU FUYI MACHINERY TECHNOLOGY CO., LTD. is specialized in manufacturing dry roller compaction for briquetting & granulating powdered material with machanical pressure. As evident in our development history we are in the unique position to have a full mastery of compacting:
Working principle
1. We use mixer mix the raw material.---Mixer
2. We use bucket elevator lift the material up to the silo.----Bucket elevator and Silo
3. The DH650 granulator compress the raw material by double rollers, it mainly depending on the mechanical pressure to compress the dry powder, so the hardness of granular is very high.---------DH650 granulator (including three parts: dosage screw feeder, forced feeder and flaking machine.)
4. Then we get the bar shape products, just as following:
So we need a crusher to crush the bar shape products into 2-4mm irregular granules.
----Crusher (you can decide the size of granules, we will design the size of crusher mesh.)
5. Finally, we will use rotary screen to sieve the final products, the unqualified products, such as dust, big granular and very small granular will be recycled for the next time granulation process. You will get the qualified 2-4mm irregular shape granules successfully.--------Rotary Screen
6. Next we use the second time rotary screen, the purpose is we want to get better result of irregular shape granules after second time screening, the appearance of irregular shape granular will looks more beautiful. -------Second Time Rotary Screen (if you don't need this, you can delete this process.)
7. The last step is automatic packaging machine. This machine will help you pack the final granular into bags. ----Automatic Packaging Machine
