Tongli Natural Gypsum Vertical Mill is an industrial equipment specially used for grinding natural gypsum. Its main purpose is to crush natural gypsum to the required fineness to meet the needs of industries such as building materials, gypsum board, agriculture and chemical industry. It is mainly composed of grinding disc, grinding roller, grading device, fan, feeding system and discharging system. The material between the grinding disc and the grinding roller is ground, and the fine powder is separated and discharged by the grading device. The material is fed into the mill through the feeding system, and the rotation of the grinding disc drives the grinding roller for grinding. The grinding roller applies pressure to crush the gypsum material, and the fan takes away the fine powder and separates the product of the required particle size through the grading device. The production capacity of natural gypsum vertical mill is usually measured in tons per hour (t/h). Common vertical mill production capacities range from 20 t/h to 200 t/h, depending on the equipment model and configuration.

Materials are uniformly fed into the center of the mill through a feeding system (such as a screw feeder or vibrating feeder). Typically, the feeding system directs the gypsum material into the center area of the grinding table. The grinding table is the main grinding component of the vertical mill, positioned horizontally and continuously rotating. The rotation of the table generates centrifugal force, distributing the material across the surface of the table. The grinding rollers are another critical component of the vertical mill, usually consisting of two or three rollers. These rollers apply pressure to the surface of the grinding table through a hydraulic system.
The rotational movement of the rollers crushes the material, which is ground between the table and the rollers. On the grinding table, the gypsum material is crushed and ground by the rollers, gradually turning into fine powder. The material moves outward on the grinding table due to centrifugal force while being crushed by the pressure of the rollers. The fan introduces air into the system, carrying away the fine powder within the mill. The airflow helps transport the fine powder from the surface of the grinding table to the classification device located above. The classification device (typically a cyclone separator or classifier) is located at the top of the mill. It separates the fine powder from the coarse particles in the airflow, with fine powder being separated and discharged by the classification device.
Coarse particles are returned to the grinding table for further grinding. The classified fine powder is conveyed to a storage silo or final product collection device through a discharge system (such as a pneumatic conveying system). This system is responsible for discharging and storing or further processing the product powder from the mill.
Increasing the pressure of the grinding rollers can enhance grinding efficiency. However, excessively high pressure may lead to equipment overload or increased wear. It is necessary to find a balance between increasing output and maintaining equipment. Adjusting the airflow of the fan can control the speed of airflow within the mill, thereby affecting material grinding and fineness. Appropriate airflow can improve the efficiency of fine powder discharge.
By adjusting the parameters of the classification device (such as rotational speed), it is possible to control the fineness and flow of the product. Optimizing the settings of the classification device helps to increase output and ensure product quality. Regular maintenance and inspection of the vertical mill are essential to ensure all components (such as grinding rollers, grinding table, classification device, etc.) are in good condition, reducing faults and downtime. Regular cleaning and inspection of the dust removal system can prevent dust accumulation and blockages. Keeping the equipment clean helps maintain stable operating conditions. High humidity materials may cause clumping issues during the grinding process.
Controlling the moisture content of the material or pre-drying it can reduce its impact on the grinding process. Using advanced monitoring systems to monitor the operating status of the equipment in real-time, including parameters such as output, energy consumption, and temperature. Through data analysis, operational parameters can be adjusted in a timely manner to enhance output.
Regularly check the wear condition of the grinding rollers and grinding table, and promptly replace severely worn components. The wear of the rollers and table can affect grinding efficiency and product quality. Regularly clean dust and impurities from the grinding rollers and table to prevent buildup that may affect the normal operation of the equipment. Inspect the wear condition of the blades and other components of the classification device to ensure it operates correctly. Regularly check the filter bags or cartridges of the dust removal system to ensure they work properly and avoid dust leakage.
Replace lubricating oil regularly as per the equipment manufacturer's recommendations to maintain good lubrication. Choosing the appropriate lubricating oil can reduce wear and improve equipment efficiency. Inspect the hydraulic system's pipes and connections to ensure there are no oil leaks. Record the operating data of the equipment and analyze performance and failure causes for preventive maintenance. Provide training for operators to ensure they master proper operating methods and maintenance skills. Establish and follow safety operating procedures to ensure safety during the equipment operation.

Insufficient roller pressure may lead to low grinding efficiency; adjust the roller pressure as needed to ensure proper grinding conditions. Insufficient or excessive airflow from the fan may affect material grinding and discharge; check and adjust the fan airflow to ensure it matches the grinding needs of the equipment. An uneven feeding system may lead to instability in the grinding process; improve the feeding system to ensure uniform feeding into the mill. Wear of the grinding rollers and grinding table can reduce grinding efficiency; regularly check the wear condition of the rollers and table, and replace them if necessary.
Failures in the lubrication system or insufficient lubricating oil may lead to overheating of the equipment. High humidity materials can easily cause blockages during the grinding process. Dust accumulation may lead to poor material flow and blockages. Uneven feeding may cause internal blockages in the equipment. Common issues with the natural gypsum vertical mill include insufficient output, unstable grinding fineness, overheating of the equipment, noise and vibration, material blockages, and excessive energy consumption.
