Product details
Aluminum Sulfate Production Process Equipment refers to a complete set of integrated machinery used to manufacture aluminum sulfate through controlled chemical reactions, concentration, crystallization, and finishing processes. This system is designed for continuous or batch production, ensuring high efficiency, stable product quality, and environmental compliance.
The equipment is widely applied in industries such as water treatment chemicals, paper manufacturing, and textile processing, where consistent aluminum sulfate quality is critical.
1. Raw Material Pretreatment & Dosing System
Automatic weighing and feeding units
Raw material storage tanks (for aluminum hydroxide and sulfuric acid)
Precise dosing pumps and control valves
👉 Ensures accurate proportioning and stable feeding into the reaction stage.
2. Acidolysis Reaction System (Core Equipment)
Closed reaction kettle (acid-resistant lined or FRP)
Agitation system (high-efficiency mixer)
Heating system (steam or thermal oil)
Temperature & pressure control instruments
👉 Enables precise control of reaction conditions (80–150°C), ensuring complete conversion and high reaction efficiency.
Working Principle
The equipment operates based on a controlled neutralization reaction between aluminum hydroxide and sulfuric acid. The process includes:
Precise dosing of raw materials
Closed acidolysis reaction under controlled temperature and pressure
Impurity removal through filtration
Solution concentration via evaporation
Cooling crystallization into solid form
Crushing, drying, and packaging of final products
This integrated system ensures a continuous, stable, and efficient production flow.
FAQ：
1. What equipment is included in an aluminum sulfate production process system?
A complete system typically includes raw material dosing units, reaction kettles, filtration systems, evaporators, crystallizers, drying equipment, and automatic packaging lines, as well as a PLC/DCS control system for automation.
2. What materials are used to manufacture the equipment?
Due to the corrosive nature of sulfuric acid, key equipment is usually made from FRP (Fiberglass Reinforced Plastic), stainless steel, or rubber-lined carbon steel, ensuring long-term durability and resistance to chemical corrosion.
3. Can the equipment handle different raw materials?
Yes. The system can be designed to process various aluminum sources such as aluminum hydroxide, bauxite, or aluminum scrap. The configuration may vary depending on the raw material characteristics and purity requirements.
4. What is the typical service life of the equipment?
With proper maintenance and high-quality materials, the equipment can typically operate for 10–15 years or longer. Components exposed to high corrosion may require periodic inspection and replacement.
