Product overview
Using a new granulation process, the precursor powder is made into granular products with high density, easy flow and less dust by physical processes such as tablet pressing, crushing and screening before calcination.
Applicable materials
Lithium iron phosphate (solid phase method, liquid phase method, iron red process, etc.)
Ternary materials
Lithium carbonate
Comparison of the influence of materials not rolled and rolled
Serial Number | Comparison project | Unrolled material | Material after rolling | Notes |
1 | Dust | Large amount of calcination dust | Low dust in the calcination section | |
2 | Bulk specific gravity | 0.4-0.6T/m3 | 0.75-0.85T/m3 | Reduce volume by more than 25% |
3 | Combustion energy consumption | High energy consumption | Low energy consumption | Save over 30% energy consumption per ton |
4 | Heating uniformity | Uneven, requires longer time | More gaps between particles for more uniform heating | Indirect reduction of energy consumption |
5 | Liquidity | Poor liquidity and easy to stick into blocks | Good liquidity with few sticky blocks | |
6 | Summary | After granulation, the energy consumption is lower and it has more advantages in the low-cost era. | ||
Characteristics of roller pelletizer
It can make the whole process automation and save labor
One time granulation can meet the needs of high density
The dust removal system makes the dust less
Fully closed operation of counter roller, safer
Special counter roll manufacturing process, more wear-resistant, safer for materials
Frequency conversion control, more power saving, more uniform density
Heavy duty gear box is produced by ourselves, which is more durable and load-resistant
The main machine can be adjusted automatically with high stability and is not easy to jam. It has obvious advantages in the same industry.
Process of roller pelletizer
The mixed precursor powder is evenly sent to the pre degassing silo through the frequency conversion fan of the buyer. The degassing silo presses the material into the forced feeder after pre degassing. The forced feeder forces the pressure roller to feed the material. After the pressure roller extrudes the material, the material is made into flakes. Then the flake material is initially crushed through the crushing system to form a mixture of particles and powder. Finally, the finished particles are screened out by the screening machine, The particles and fine powder that are less than the requirements of finished products return to the system for granulation.
