using a magnetic drum understand this knowledge before

Magnetic filter roller (magnetic roller) mainly used to remove powder, flake and granular material in the ferromagnetic impurities  widely used in ceramics, electricity, mining, plastics, chemical

Workers, rubber, pharmaceutical, food, environmental protection, pigments, dyes, electronics, metallurgy and other industries.
Magnetic drum including oil cooling motor, gear box, electric drum shell and shaft, oil-cooled electric motor mounted on the shaft, the shaft ends with electric roll through the end cap

Cylindrical shell is magnetic name tags connected at both ends, oil cooler motor output shaft via a reduction mechanism with fixed electric drum shell wall flange ring gear meshing, the electric drum shell

Is fixedly connected with the outer wall of the magnet installation even polygonal tube, the mounting tube outer sides of the polygon of even non-magnetic screws are connected by a permanent magnetic strip, and each of the permanent magnetic strip

Multiple magnetic polarity direction stacking block close abutment, each of the two adjacent magnetic polarity opposite to the magnet even polygonal periphery of the mounting cylinder and has non-magnetic

Magnetic stainless steel Drawer Magnet cylinder, the cylinder ends through non-magnetic stainless steel cover and electric drum is connected to both ends of the outer wall of the housing. Alternatively, you can directly to the electric drum shell

Even polygonal outer wall to the other structure unchanged.
