The gypsum vertical mill is mainly composed of feeding device, grinding disc, grinding roller, classifier, transmission device and other parts. Its working principle is as follows:
Feeding: Gypsum raw materials are evenly fed into the center of the grinding disc inside the mill through the feeding device.
Grinding: The grinding disc rotates under the drive of the transmission device, and the gypsum raw material on the grinding disc moves towards the edge of the grinding disc under the action of centrifugal force. During the movement, the raw materials are subjected to the rolling and grinding action of the grinding roller. The grinding roller is pressed onto the grinding disc through a hydraulic system or spring device, applying pressure to the raw materials, causing the gypsum raw materials to be crushed and ground into fine powder.
Grading: The finely ground gypsum powder rises with the airflow and enters the classifier. The classifier uses a rotating impeller or other grading device to grade gypsum powder in the airflow. The coarse gypsum powder is separated by the classifier and returned to the grinding disc for further grinding, while the fine gypsum powder that meets the requirements is discharged from the mill with the airflow and enters the subsequent dust collection device for collection.
Airflow circulation: There is a set of airflow circulation system inside the mill. External air enters the mill through the air inlet, comes into contact with the raw materials on the grinding disc, and carries the ground gypsum powder up. After passing through the classifier at the top of the mill, a portion of the airflow containing fine powder enters the dust collection device, while another portion of the airflow returns to the bottom of the mill through the circulation pipeline and participates in the grinding process again, forming a circulation of airflow.
This working principle makes the gypsum vertical mill highly efficient, energy-saving, environmentally friendly, and capable of continuous grinding and grading of gypsum raw materials, producing gypsum powder products that meet different needs.
Application Showcase
* Architectural gypsum powder: α/β gypsum powder production line
* Desulfurized gypsum: resource utilization of by-products in power plants
* Phosphogypsum treatment: solid waste reduction in the fertilizer industry
* Overseas EPC projects: providing turnkey services from design to installation
Problem Solution Format for Customer Pain Points
* Traditional ball mills have high energy consumption → The power consumption of the vertical mill system is only 22-24kWh/t
* Moisture containing gypsum blocking equipment → patented air sweeping structure anti sticking wall design
* Instability in fineness control → Real time adjustment of roller pressure by hydraulic pressure system
