Title:
A magnetism selecting method and magnetism sorting equipment
Document Type and Number:
Japanese Patent JP6015335
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a magnetic separation method that can separate ferromagnetic particles with high concentration, even if using a dry type magnetic separator, when magnetically separating the ferromagnetic particles from powder and granular materials that contain the ferromagnetic particles.SOLUTION: A magnetic separation method is characterized by sieving powder and granular materials (a) to a sieve 3 having a mesh size of at least the target maximum grain size of powder and granular materials (a) and less than two times of the target maximum grain size, directly receiving the powder and granular materials (a) under the sieve by the transport surface of a feeding device 1, and transporting and supplying this materials to a magnetic separator 2. The powder and granular materials (a) are sieved to the sieve to physically remove the aggregation, and the powder and granular materials (a) under the sieve are directly received by the feeding device 1 and supplied to the magnetic separator 2 as it is. Accordingly, even in the case of the powder and granular materials (a) with small particle sizes, the ferromagnetic particles can be separated with high concentration.
