Product Description

Product Details

Product Description

Half magnetic drum separator also named half magnetic roller is composed of a revolving round stainless steel cover and a shaft to generate a half disc (180 degree) stationary magnetic field . It becomes an automatic separating system when the drum is driven by a motor.

 

Application

Half magnetic drum separator is mainly used to remove or sort ferrous fines, tramp iron and other ferromagnetic impurities from bulk dry material flow such as iron ore, grain, sand, gravel, plastics, wood, waste, cullet, etc.

 

Main Features
1. Continuous self-cleaning design is suitable for automatic production line.
2. Housing material is 304 or 316L stainless steel which has good corrosion resistance performance.
3. No electric power required to generate magnetic field.
4. Magnetic strength can be chosen by customers.

Remarks:
1. The SST results differ from coating. In general, Salt Spray Test result for the magnets with barrel plating (normally for small size of magnets), is better than the ones with rack plating (normally for big size of magnets).
2. Salt Spray Test (SST) condition: 5% NaCl, 35°C, continuously spray a certain time, test whether there is corrosion on plating/coating surface.
3. Pressure Cooking Test (PCT) condition: 2 atm, 95% RH (Relative Humidity), 121°C to test the plating/coating adhesion. (Zinc, Passivated/Phosphated, and Epoxy not suitable for PCT).
4. Other test methods for plating/coating: Drop Test, Cross Cut Test, Heating and Spilling Test, Constant Temperature, Humidity Test, etc.
