1) automatic dry magnetic separator mainly aims at the positive and negative powder materials research and development of new iron machine, its magnetic characteristics for large Angle, many poles, the machine is the average of absolute value of the magnetic flux density of, play its role, magnetic system according to the ore properties of different design field;
2) electromagnetic powder machine in the process of choose don't need to overcome the resistance of the material and the gravity effect, when non-magnetic minerals from magnetic field, under the action of gravity, for good and magnetic mineral separation;
3) increased the mechanical vibration device, electromagnetic powder machine can not only improve the effect of iron removal, and easy to realize abandon iron;
4) high magnetic field intensity.
5) cavity structure is reasonable, the iron thoroughly clean.

Sludge by wet sludge silo, falling into a double-axis screw conveyor, through mixer and molding machine cut sludge into strips, relying on gravity to slow walking network of low-temperature sludge driers, hot dry winds from the bottom of the net belt to rise at a faster pace, contact with the sludge in the process of sludge drying, drying sludge adopts full closed after shaftless screw conveyor conveyor drying system, by car, transportation, for subsequent use.
