Common granulators include double roller granulator, npk granulator, disc granulator machine, tooth stirring granulator, rotary drum granulator, etc. How much do you know about roller granulator, it is suitable for What raw materials are used, what are the advantages, and what should be paid attention to when using them?
The granulation raw materials of the double roller granulator can be used for the granulation of organic fertilizers such as livestock manure, kitchen waste, industrial waste, straw leaves, trough residues, oil cakes, etc, compound fertilizer granulation such as npk manufacturing process, chemical industry , granulation of feed, etc.
Advantages of double roller granulator：
1. Low energy consumption and energy saving road roller extrusion granulation is a kind of material granulation at room temperature. Compared with other methods, no drying measures such as fuel and gas are required.
2. Steam granulation is a commonly used production method of binder-free compound fertilizer in my country. Dry granulation does not require another additive, and only needs to use the intermolecular force of the material itself, simplifying the process and reducing energy consumption.
3. The low investment is due to the saving of the drying process, the low rate of return (about 15% of the total feed of the extruder), the simple process flow and the low investment.
4. The consumption capacity of extrusion granulation is electricity, and the environmental protection has no three wastes discharge, which is in line with the national basic environmental protection policy and the environmental protection development strategy of Taiwan enterprises.
Precautions for operation of double roller granulator：
1. Before starting the roller granulator, please check whether there is any debris in the machine.
2. Check whether the machine on the roller granulator is normal.
3. It is strictly forbidden to start the roller granulator under load.
4. After the drum granulator is started, check whether the rotation direction is correct. If it is reverse rotation, please stop adjusting immediately to ensure stable rotation and no noise. Then start production.
