Air classifier mill is a kind of equipment used for ultra-fine grinding and classification of materials, and it has a wide application in multiple fields, such as mining, chemical industry, building materials, etc. With the continuous improvement of modern industry’s requirements for powder fineness and purity, air classifier mill has become one of the core equipment for ultra-fine powder processing.
Qingdao Epic Powder Machinery Co., Ltd. is a professional manufacturer of powder processing equipment. Our products include powder grinding equipment, classification equipment, modification equipment and related auxiliary equipment. Air classifier mill is one of our products, which includes four types: MJW-W, MJW-L, MJW-A, and MJL-W, with reliable quality and reasonable prices, especially the MJW-W type, its performance can be comparable to the ZPS air classifier mill produced in Germany.
Features of air classifier mill from Epic Powder
◆ Stable and flexible flow field, which is suitable for the efficient grinding of medium – fineness products, and it has low energy consumption.
◆The built-in high-performance turbo air classifier ensures a narrow particle size distribution, steep cut-off efficiency, and high classification accuracy.
◆The system operates with large air volume and low grinding temperature, making it suitable for processing heat-sensitive materials.
◆ The grinding hammers and girth gear are made of ultra-hard materials, and all easily worn parts are treated with wear-resistant measures. This greatly extends the service life and significantly reduces the contamination of iron impurities.
◆ It can meet the requirements of fully ceramic clean production.
◆ It has a high degree of automation. The whole system operates under fully enclosed negative pressure, with no dust pollution, and the collection efficiency is over 99.9%.
◆ It is suitable for the grinding of flammable and explosive materials.
Safety operation guidelines
① Start and stop sequence
— Startup sequence: Follow the no-load starting principle. First, turn on the fan. After the airflow stabilizes, start the mill, and finally begin feeding the materials.
— Shutdown sequence: First, stop feeding the materials. After emptying the equipment, stop the mill. Finally, turn off the fan to prevent the remaining materials from causing blockage.
② Material control
— Control the moisture content of the materials (usually ≤ 5%). Excessively high moisture content is likely to cause adhesion or blockage.
— Avoid the entry of impurities with excessively high hardness (such as metals). Iron removal or pretreatment should be carried out in advance.
③ Maintenance and inspection
— Check whether the components such as the fan, classifying wheel and pipelines are damaged or loose, and whether their sealing performance is good to prevent powder leakage or air flow leakage.
— Regularly check whether the lubricating oil in key parts such as bearings (bearing temperature should be ≤70℃) and gears is sufficient to avoid overheating or damage caused by dry friction.
— Check whether the safety devices such as protective covers, emergency stop button, and pressure gauges are functioning properly to prevent mechanical injuries or abnormal pressure.
④ Safety protection
— Equip anti-static dust removal equipment (such as мяшковы фільтр) to ensure that the dust concentration in the working area is lower than the lower explosion limit.
— Operators are required to wear dust masks, safety goggles and earplugs to prevent inhalation of dust and noise-induced injuries.
— During operation, it is forbidden to open the maintenance door to prevent high-speed components from causing injuries.
⑤ Installation requirements
— The equipment should be installed in an area with good ventilation, and avoid environments with high temperature and high humidity.
— The base of the equipment needs to be leveled and calibrated to reduce vibration.
⑥ Emergency Management
— When shutting down the equipment for maintenance, cut off the power supply and hang a warning sign to prevent accidental startup.
— Equip with fire extinguishing equipment to deal with spontaneous combustion or other sudden fire situations.
⑦ Record and track
— Establish a maintenance file and record information such as wear and tear replacement, fault handling, etc., so as to carry out regular preventive maintenance.
Implementing the above measures regularly can significantly improve the stability and efficiency of air classifier mill, while reducing safety risks. For specific details, it is necessary to refer to the equipment manual and make adjustments according to the actual working conditions.
