How HGM micro powder grinding mill process 400-600 Mesh Calcium Hydroxide

To process calcium hydroxide into 400-600 mesh using the HGM micro powder grinding mill, you would typically follow these steps:

  • Preparation of Calcium Hydroxide: Ensure that the calcium hydroxide (Ca(OH)₂) material is properly prepared and dried to reduce moisture content. This step is essential for efficient grinding and achieving the desired fineness.
  • Feeding: Load the prepared calcium hydroxide material into the grinding chamber of the HGM micro powder grinding mill. The material can be fed manually or through a feeding system, depending on the specific setup of the grinding mill.
  • Grinding: Start the grinding mill and adjust the operating parameters, such as grinding pressure, rotation speed, and airflow, to optimize the grinding process for calcium hydroxide. The material will undergo repeated grinding and impact within the grinding chamber, resulting in the reduction of particle size.
  • Classification: As the ground material exits the grinding chamber, it passes through a classifier, which separates the finer particles from the coarser ones. The classifier helps to control the particle size distribution and ensures that the final product meets the desired specifications.
  • Collection: The finely ground calcium hydroxide powder, now in the 400-600 mesh range, is collected in a cyclone separator or a bag filter system. This ensures that the product is properly separated from the airflow and can be safely collected for further processing or packaging.
  • Quality Control: Periodically monitor the particle size distribution and fineness of the ground calcium hydroxide using particle size analysis techniques or sieve analysis. Adjust the grinding parameters as needed to maintain the desired product quality and consistency.
  • Packaging or Further Processing: Once the desired particle size is achieved, the ground calcium hydroxide powder can be packaged for sale or further processed into various forms, such as granules or slurries, depending on the intended application.

By following these steps and optimizing the operation of the HGM micro powder grinding mill, you can efficiently process calcium hydroxide into the desired 400-600 mesh range with high precision and consistency.

HGM micro powder grinding mill structures and working principle

The HGM micro powder grinding mill consists of several key components, each playing a crucial role in the grinding process. Here’s an overview of its main structures and working principle:


  • Grinding Mill Body: The main body of the HGM micro powder grinding mill houses the grinding chamber, where the grinding process takes place. It is typically made of sturdy materials to withstand the high-pressure grinding environment.
  • Grinding Rollers and Rings: Inside the grinding chamber, there are several sets of grinding rollers and rings. These components rotate at different speeds to grind the material between them. The rollers and rings are often made of high-quality alloy steel for durability and wear resistance.
  • Classifier System: The classifier is located at the top of the grinding chamber and is responsible for separating the fine particles from the coarse ones. It ensures that only the desired particle size range exits the grinding mill.
  • Air Blower and Airflow System: An air blower generates the airflow that carries the ground material out of the grinding chamber and into the classifier. The airflow system helps to control the particle size distribution and transport the finished product to the collection system.
  • Electrical Control System: The HGM micro powder grinding mill is equipped with an electrical control system that regulates the operation of various components, including the motor, air blower, and classifier. This system allows for precise control over the grinding process parameters.
  • Collection System: The finely ground powder is collected in a cyclone separator or a bag filter system. This system separates the powder from the airflow and ensures that it can be safely collected for further processing or packaging.

Working Principle:

  • Material Feeding: The raw material, such as calcium hydroxide, is fed into the grinding chamber through a feeding device or conveyor belt.
  • Grinding Process: The material is ground between the rotating grinding rollers and rings due to the centrifugal force and pressure generated by the grinding mechanism. As the material is continuously fed into the grinding chamber, it undergoes repeated grinding and impact until it reaches the desired fineness.
  • Classification: The ground material is carried by the airflow into the classifier, where it is separated into fine particles and coarse particles. The fine particles, within the specified size range, are collected as the final product, while the coarse particles are returned to the grinding chamber for further grinding.
  • Collection and Discharge: The finely ground powder is collected in the collection system, while the excess airflow is discharged through the exhaust system. The collected powder can then be packaged or further processed according to the desired application.
