Document Type and Number:
Japanese Patent JP3842658
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To sieve the copper slag having an effective grain size of approximately 1500-3500 μm in a case of using the copper slag as a sand blasting material.
SOLUTION: This classifying method of the copper slag uses a jumping screen or a special sieving device applying the principle same as the jumping screen to classify the water-containing copper slag.
