Process
Classifying and Ball Mill Production Line working principle
Process characteristics
From Germany
The process is directly derived from the German IVA company.International standard non metallic mineral production line.
Combine with Parallel and series
The process mainly includes crushing (usually using two-stage crushing), grinding, grading, packaging, bin, conveying, lifting and so on. Ball Mill can be connected with multiple classifiers for parallel classifier, can also connected with multiple series classifier, simultaneously produce multiple sizes products. The ball mill and classifier form a closed loop system.
Tailored as minerals
The ball mill is selected according to the hardness, grindability, particle size and output of the mineral. The lining shape and ball (segment) are tailored according to years of engineering practice experience, maximize the grinding efficiency of the ball mill. Reduce product energy consumption.
Select model by fineness
The classifier can choose different models according to different fineness of the product. The FW series classifier can be adapted to the classification of D97: 3 ~ 20 micron products. The FL series classifier can be adapted to D97: 8 ~ 45 micron products. Each classifier has a wide range of product adjustment, the market adapts to a wide range.
Flexible product particle size control
When a production line produces multiple varieties at the same time, we can use multiple classifiers in series. Through the optimized combination of coarse and fine classifier, we can ensure the lowest energy consumption, the most convenient adjustment of the particle size, reducing overgrinding to the minimum.
Make program by scale
According to the scale of investment of customers, we can design different plant structures and equipment layout schemes to provide the most cost-effective configuration system. For example, the equipment layout with annual output of less than 20,000 tons is mostly arranged in a single-storey factory layout, and the conveying system adopts spiral conveying. The packaging can be manually packaged. The equipment of scale of over 20,000 tons is arranged in a three-dimensional arrangement of multi-storey buildings. The conveying system adopts pneumatic conveying, the packaging adopts automatic packaging and equipped with palletizing system.
Reduce noise and discharge
We using special design for environmental protection to minimize noise through vibration reduction and partial soft connection of the equipment. By using high quality filter materials, ensure the minimum dust emissions.
Automated control
The electronic control system uses program control to control the entire production process, from feed bin, grinding and classifying, to product packaging.
Provide value-added services
We can provide customers with additional services, such as beneficiation, coating, upgrading of old production lines etc., to ensure the maximum benefit of users by extending to both ends of the product.
