Zhang Jingjie 1. System advantages
The ball mill grading system is applied to non-mineral, especially ultra-fine deep processing of heavy calcium, which has been widely used in foreign countries, and the introduction into China is a matter of recent years. *The typical production line was built in 2000. It was first built by Sichuan Baoxing Micro-Powder Powder Co., Ltd. to introduce the technology and equipment of German IVA Company.
The system has the advantages of stable running performance, stable product quality, controllable particle size distribution, flexible variety and scale selection, low production cost and low maintenance rate, and is especially suitable for ultra-fine processing of heavy calcium.
Compared with ring roll grinding and vertical grinding, the system produces 800 mesh finer products with lower energy consumption. Although the energy consumption is 600-800 mesh, the energy consumption is high or equivalent, but because the system is stable and reliable, there are no wearing parts. The long-term operation cost is not high, and the product quality is more stable and uniform, and the particle size distribution is more reasonable.
2. Process design points
Considering the advanced nature and economy of the system, the flexible distribution design makes the system more flexible. Including optimizing the aspect ratio of the ball mill and the particle size adjustment range of the classifier and the series-parallel combination of the system, it can produce various products with special particle size distribution including narrow particle size distribution and low oil absorption value to meet the needs of different applications and increase the added value of the product.
Quantitative control and self-discipline automatic adjustment of various process parameters in the system operation to meet the process requirements of producing different products and fully guarantee the product quality and the stability of the production process. Including quantitative feeding of ball mill and quantitative addition of grinding aid, quantitative adjustment of classifier feeding, rotation speed, gas flow, etc., including over-flow, overload and high-temperature monitoring of key equipment such as ball mill, classifier and fan to ensure the whole Continuous and safe production of the production line.
The interlocking process program control with the industrial computer as the core enables the main parameters, operation and error status to be displayed, and the automatic control of the entire production line is realized, which is clear and easy to operate.
3. Equipment selection points
Ball mill:
The design is different from the traditional cement grinding and mining and metallurgy grinding, and meets the requirements of German superfine filler grade mineral processing.
Optimize the aspect ratio to prevent over-grinding and achieve a good grinding effect
Optimize the opening ratio and opening design of the jaws, and use smaller grinding media to increase the fineness of the grinding.
The slab-type grinding tail discharges, the discharging is smooth, there is no grinding phenomenon, and the cylinder does not need to be cooled.
Optimize the shape and material of the lining and grinding media, according to German requirements, reduce the damage rate and improve the grinding efficiency
Grinding media according to product requirements, reasonable ratio, high filling rate, high efficiency
Optimize the matching of drive and grinding energy consumption, and save energy
And the classifier forms a closed system, negative pressure conveying, no dust
Grader:
High-speed turbine multi-rotor classifier is used to ensure a wider range of particle size adjustment
Designed according to German requirements, precise process control ensures excellent vertex cutting
Adjustable flushing airflow for improved classification efficiency
The material directly enters the classification area and is not classified and then mixed with coarse powder.
Optimize rotor design for low energy consumption
The particle size distribution of the product can be adjusted by different arrangements of the classifier to meet the technical requirements of different products.
Quantitative system:
The ball mill feeds a precise dosing system that stabilizes the feed even if the density of the material changes.
The high-precision metering pump sprays the grinding aid into the mill in an accurate time and quantity according to the product fineness requirements.
Airflow control valve with airflow measurement system for precise control of flow and flow rate of staged airflow
4 Conclusion
The ball mill grading system is a good choice for large-scale dry processing of ultra-fine calcium.
The flexible design of the process and the optimal selection of equipment must be selected for the product outline and market positioning.
IVA has adopted this process and equipment configuration in many domestic manufacturers and IVA and Mai Cologne in the country. It has gained rich experience and can produce various products according to international standards and special requirements of users, and has achieved very satisfactory results.
Warning:
1. In the face of diverse opinions, various process plans and performance indicators, investors can compare the current international technical solutions and indicators of international Zui.
Zui's good method is to visit several times on the heavy calcium production line. It’s more obvious than one.
2. According to the German technical standards, we can provide project design drawings and equipment ordering materials such as project plan, process flow chart, equipment layout drawing, construction condition drawing, pipeline auxiliary material table, schedule sheet, etc. according to the customer investment scale. Our formalized design makes customers feel more at ease, saves time, effort and money.
3. The grader is the key equipment in the entire production line. The cooperation between Qingdao Mai Cologne and German IVA has made the import classifier localized, providing domestic users with more affordable equipment and more convenient services, and ensuring that our production line has reached the international advanced technology level and guaranteed heavy calcium. The quality indicators of the products conform to international standards.
The Malvern N or Cilas laser particle size distribution instrument is the good judge of Zui.
4. In today's risk increase, market segmentation -
German IVA company's rich practical experience in engineering design, process know-how, equipment selection, installation and commissioning, coupled with its rigorous and conservative reputation, will ensure that the risk of investor production line construction is zero!
And in the continuous cooperation with famous powder companies at home and abroad, accumulated some performance requirements on product application, to ensure that investors' products are closer to market demand.
