NOTICE TO USER

Thank you for purchasing a CG/AT-CG electromagnetic separator.

This unit generate a high magnetic flux density and is free from magnetics leakage. In addition this unit is

capable of efficiently removing iron powder from materials by passing through a magnetized screen while

dispersing fine powder with poor fluidity by arranging a multi-layered screen with its tip at an acute angle into

a cylindrical interior and giving them fine vibrations.

AT-CG type is equipped with an iron powder auto-discharge device. By setting the timer, the automatic iron

powder discharge device is activated, and the removed iron powder can be periodically discharged outside the

device without stopping the Unit.

INSTRUCTION MANUAL (1)
