Summary
The GF series dry roller pressing system adopts international advanced granulation technology, which produces high density, easy flow, and low dust granular products from precursor powder through physical processes such as pressing, crushing, and screening before false firing. The loading capacity is increased by 30-40%. Our company can customize complete sets of processes or single machine accessories for users, assist in installation and debugging, welcome customers to come and experiment with materials, and can also handle material processing on behalf of users.
Roller pressing granulator process
The mixed precursor powder is transported into the large material bin, and then uniformly fed into the pre degassed material bin through a quantitative screw. The degassing screw presses the material into the forced feeder, which forces the feeding roller to feed it. After the material is compressed by the pressure roller, it becomes flakes. The flake material is preliminarily crushed by the crushing system, forming a mixture of particles and powder. Finally, the screening machine screens out the finished particles, The particles and fine powder that are smaller than the requirements of the finished product are returned to the system for recycling granulation.
Comparison of the effects of materials without rolling and materials after rolling
Number | Comparison project | Unrolled material | Material after rolling | Notes |
1 | Using labor (person/day) | 1 | 1-2 | Visual automation level |
2 | Dust | Excessive dust in the calcination section | Low dust in the calcination section | |
3 | Bulk specific gravity | 0.4-0.5T/m³ | 0.75-0.85T/m³ | Reduce volume by more than 35% |
4 | Energy consumption before calcination | Only conveying energy consumption | Granulation energy consumption of 20 yuan/T | |
5 | Calcination energy consumption | High energy consumption | Low energy consumption | Save over 1000 yuan per ton |
6 | Heating uniformity | Uneven, requires longer time | More gaps between particles for more uniform heating | Indirect reduction of energy consumption |
7 | Mobility | Poor liquidity and easy to stick into blocks | Good liquidity with few sticky blocks | |
8 | Summarize | After granulation, the energy consumption is lower and it has more advantages in the low-cost era | ||
Characteristics of roller press granulator
◆ It can be fully automated, saving labor.
◆ A single granulation process can meet the required high density.
◆ The dust removal system reduces dust.
◆ Fully enclosed operation for silver, safer.
◆ The rollers are sprayed with high-strength stainless steel, which is more wear-resistant and durableLow switching frequency.
◆ Variable frequency control, more energy-efficient, and more uniform density.
◆ The heavy-duty gearbox is self-produced for greater durability and load resistance.
◆ The host is automatically adjustable, with high stability and is not easy to get stuck. It has obvious advantages in the same industry.
◆ Materials with high air content in the fine powder of raw materials can also be equipped with our company's patented three-level pre degassing, which has higher production capacity and more stable equipment.
