Production Process of Aluminum Sulfate Plant
A typical complete manufacturing line includes the following main sections:
1. Raw Material Feeding & Dosing System
High-precision weighing and feeding system for:
Aluminum hydroxide (Al(OH)₃)
Industrial sulfuric acid (H₂SO₄)
Ensures accurate ratio control and stable reaction performance.
2. Acidolysis Reaction System (Core Process)
Aluminum hydroxide reacts with sulfuric acid in a sealed reactor under controlled conditions:
Temperature: 80–150°C
Closed reaction system
Automated temperature and pressure control
This stage produces high-purity aluminum sulfate solution.
3. Crystallization System
The concentrated solution is transferred to a steel belt or cooling crystallization unit to form solid aluminum sulfate crystals.
Key advantages:
Uniform crystal formation
Continuous production
Stable particle quality
4. Crushing & Drying System
Crystals are processed into different product forms:
Flakes
Granules
Powder
This allows flexible production based on market demand.
5. Automatic Packaging System
Final products are packed using an automatic weighing and sealing system to ensure:
Dust-free packaging
Accurate weight control
Moisture protection

FAQ
1. What is a complete aluminum sulfate manufacturing line?
A complete aluminum sulfate manufacturing line is an integrated chemical production system used to produce aluminum sulfate from raw materials such as aluminum hydroxide and sulfuric acid. It includes raw material dosing, acid reaction, crystallization, crushing, and automatic packaging. The system is designed for continuous production with stable quality and high efficiency.
2. What raw materials are used in aluminum sulfate production?
The main raw materials include:
Aluminum hydroxide (Al(OH)₃)
Industrial sulfuric acid (H₂SO₄)
These materials undergo an acidolysis reaction to form aluminum sulfate solution, which is then processed into solid products such as flakes, powder, or granules.
3. What are the main types of aluminum sulfate produced by the plant?
A complete production line can manufacture different grades of aluminum sulfate, including:
Industrial grade aluminum sulfate
Low iron aluminum sulfate
Iron-free aluminum sulfate
Drinking water treatment grade aluminum sulfate
Different grades are used for different industries such as water treatment, papermaking, and chemical processing.
4. What industries use aluminum sulfate?
Aluminum sulfate is widely used in:
Water treatment (drinking water and wastewater treatment)
Paper manufacturing (sizing and filler retention)
Textile dyeing (mordant and fixing agent)
Leather tanning (improving flexibility and durability)
Chemical production (raw material for other aluminum salts)
It is a key industrial chemical with stable global demand.
