Testing the sorting ability of an electromagnetic dry powder magnetic 
separator is a key step in ensuring its normal operation and meeting production 
requirements. The following are commonly used methods for testing sorting 
ability:
1、 Sample preparation
Firstly, prepare the material samples to be processed. The sample should 
represent the materials processed in actual production, and it is necessary to 
understand the physical properties of the materials (such as particle size, 
magnetism, humidity, etc.), which helps to ensure the accuracy of the test 
results.
2、 Determine test parameters
According to the model and design requirements of the electromagnetic dry 
powder magnetic separator, set appropriate working parameters such as 
electromagnetic field strength, vibration frequency, material passing speed, 
etc. These parameters will directly affect the sorting effect, so they should be 
set according to the equipment manual or actual requirements before testing.
3、 Perform preliminary sorting
Start the equipment and perform preliminary material handling. Evenly feed 
the material into the feed inlet of the magnetic separator to ensure stable 
material flow and prevent blockage or overload. Record various operational data 
during the sorting process, such as feed quantity, processing speed, etc.
4、 Collect sorting results
During the sorting process, the magnetic and non-magnetic materials from the 
magnetic separator are separated and discharged, and their quality and quantity 
are compared and analyzed. These data can be used to calculate recovery rate, 
sorting accuracy, and other sorting performance indicators.
5、 Analyze the sorting effect
Evaluate the sorting effect of the magnetic separator by analyzing the 
sorting results. The main evaluation indicators include:
-Recovery rate: refers to the ratio of effectively recovered magnetic 
materials to the total magnetic materials.
-Removal rate: refers to the proportion of magnetic impurities separated from 
non-magnetic materials.
-Sorting accuracy: Evaluate the discrimination between magnetic and 
non-magnetic materials during the sorting process to determine if there has been 
a misclassification.
6、 Experimental adjustment
According to the preliminary test results, the working parameters of the 
electromagnetic dry powder magnetic separator can be adjusted, such as changing 
the current intensity, magnetic field gradient, etc., to further optimize the 
sorting effect. Through multiple experimental adjustments, the optimal operating 
conditions were found to ensure the best performance of the equipment in actual 
production.
7、 Data recording and reporting
After completing the test, detailed test data should be recorded and a report 
should be generated. The report should include the working parameters of the 
equipment, test results, sorting capability analysis, and possible optimization 
suggestions. Based on these data, decide whether adjustments or maintenance are 
needed for the equipment.
Through the above testing steps, the sorting ability of the electromagnetic 
dry powder magnetic separator can be effectively evaluated, ensuring that it 
achieves the expected results in actual production and providing a basis for 
further equipment optimization and improvement.
