The equipment is mainly used for the industrial production of passivated magnesium powder for hot-metal desulfurization.
The Passivated Magnesium Powder Production Machine is primarily used for:
Production of passivated magnesium powder
Production of magnesium-based desulfurizing agents
Passivation treatment of magnesium powder for iron and steel metallurgy
Mixing of magnesium powder with solid and liquid additives
Controlled heating and drying of passivated magnesium powder
Preparation of magnesium-based materials for hot-metal desulfurization
Passivation treatment is used to modify the surface characteristics of magnesium particles, helping to control their reactivity and improve their stability during storage, handling and subsequent application.
According to the specified production formulation, the feeding system and liquid injection system respectively deliver the required solid and liquid raw materials into the mixing and drying machine.
The materials are rapidly and uniformly mixed inside the machine. During the mixing process, the heating and temperature-control system heats the material according to the specified process requirements.
Under controlled mixing and heating conditions, the passivation treatment takes place. After the required reaction and treatment period, the material undergoes controlled drying and cooling.
Depending on the final product requirements, the cooled material can subsequently be screened or classified to obtain the required particle-size distribution.

The complete passivation machine mainly consists of the following systems:
The main processing unit for intensive mixing, controlled heating, passivation treatment and drying of magnesium powder and other process materials.
Used to introduce liquid additives or passivating agents into the mixing chamber according to the specified formulation.
Used to feed solid raw materials into the main mixing and drying machine.
The feeding system can be supplied according to the customer's process requirements and contract configuration.
Provides a safe and convenient operating and maintenance platform for the main equipment and auxiliary systems.
Used for centralized electrical control and monitoring of the main drive, heating system, temperature-control system and other auxiliary equipment.
Provides controlled heating and temperature regulation according to the requirements of the passivation and drying process.
Used for controlled cooling of the processed material after the passivation and drying stages.
The equipment integrates mixing, heating, passivation treatment, drying and cooling functions into one processing system.
The mixing system is designed to provide effective contact between magnesium powder and the required solid and liquid additives, helping to achieve a uniform treatment effect.
The heating and temperature-control system provides controlled heating according to the specified process parameters.
