The gravitational force acts in the first crushing assembly 3, and the non-magnetic member C is sent to the third magnetic separation assembly 7, so that the first magnetic separation assembly 2 and the first crushing assembly 3 can be placed side by side to reduce the overall height to achieve Space saving effect.

The magnetic member B in the first crushing assembly 3 that enters the uppermost part will fall onto the first projecting part 33, and the first projecting part 33 will rotate through the power given by the first power element 32, whereby the first projecting part 33 The pushing effect ejects the magnetic member B out of the first projecting part 33, and strikes the first outer casing 31 to achieve the crushing effect by means of collision (bead hit). The crushed magnetic member B will fall further to another The first crushing assembly 3a crushes again, and the magnetic member B crushed by each first crushing assembly 3 is transported by the second lifting member 82 to the second crushing assembly 4 and passes through the second ejection section 43 , The cooperation of the second power element 42 and the second outer casing 41 again crushes the magnetic member B.

The method is the same as the first magnetic separation assembly 2, so it will not be described in detail. Since the crushed magnetic part B can become finer particles, it can completely separate the magnetic part B and the non-magnetic part C magnetically and prevent In the first magnetic screening, the screening is not complete enough to mix the non-magnetic piece C into the magnetic piece B, and then the magnetic piece B after screening will be sent to the particle size screening element 6, and the non-magnetic piece C after screening Sent into the third magnetic separation assembly 7.

The magnetic pieces B entering the particle size screening element 6 will be screened and classified according to the particle size of each magnetic piece B, to be screened into magnetic pieces B of various sizes according to the user's needs.

The magnetic screening method is the same as that of the first magnetic separation component 2. Therefore, it will not be described in detail to prevent the mixing of the metal with magnetism into the non-magnetic component C. The magnetic component B screened by the third magnetic separation component 7 will It is sent into the first lifting member 81, so that the above steps are performed again, and the non-magnetic member C after screening will be stored in a storage container, so that the objects to be sorted can be completely completed through the above steps A (slag) is classified into a magnetic member B (iron-containing substance) with magnetism and the remaining non-magnetic member C.
