Classifying and Ball Mill Production Line
Applicable Materials:
Calcium carbonate (calcite, marble, lime stone, chalk), quartz, zircon, paillite, barite, kaoline, dolomite, magnesite, alumina, super fine cement, slag, steel slag.
Source of Technology
Germany technology, international standard non-metallic minerals production line.
Technical Process
The process mainly includes(two-stage crushing), size classification and reduction, package, magnetic separation, transportation, lifting etc. In conjunction with several classifiers in parallel or series, several different products can be obtained at the same time.
Ball Mill
Special design to ball mill which will be selected on the basis of hardness, grindability index of material to be ground, feed size, particle size and hourly capacity, customized to the liner. Selection of grinding ball and rod can improve grinding efficiency farthest and reduce the energy consumption.
Classifier
Different models of Classifier could be selected depending on different fineness of products. FW series Classifier are suitable for classifying of D97：3～20μm products, FL series for classifying of D97: 8～45μm products. Wide range of adjustment is available with each Classifier and the application is extensive in market.
Flexible control of product particle size
The production line are designed and optimized to match with several classifier in series, the particle size can be controlled, and several products can be obtained at once, low energy consumption, free from over-crushing.
Low noise and emission
Environment protection design to the vibration damper, component soft connection and filter bag result in lowering noise and dust.
Automatic Control
The electric control system employs programmed control for the entire process from feeding, classifying and grinding to packing.
Provide value added service
Add-on services to customer such as mineral processing, modification, granulation and equipment upgrading
Capacity matching
ALPA’s ball mill classifying production line, ball mill and classifier work well together, can complement each other, high efficiency, large output, stable operation and stable product quality.
Influencing factors of Ball mill output
Feeding particle size and distribution;
Scientific calculation of the length to diameter ratio of the mill;
Speed of the ball mill and motor power of the mill motor;
Shape and material of ball mill medium;
Loading quantity of the mill medium.
Influencing factors of Classifier output
Powder concentration;
Turbine classifier rotate speed;
Air volume and Air pressure;
Classifying efficiency;
Particle size distribution;
Product fineness.
The relationship between Ball Mill and Classifier
Ball Mill Output = raw material feed amount + coarse material return after classifying
Classifier Output = classifier throughput – classified coarse material
Classifier throughput = Ball Mill output
