The Semi-Automatic Easy Clean Magnetic Grid Box from Greenwood Magnetics is an inline magnetic separator for use in vertical chutes for the efficient extraction of ferrous particles in powder or granular materials being processed.
We offer two types, A and B.
Type A uses a “scraper” design to remove metal particles and can be manufactured to 12000 gauss on the contact surface. This design is not suitable for sticky products such as sugar.
Type B does not have a scraper, the inner magnetic cores slide out, and can be manufactured to 10000 gauss on the contact surface. This design can be used for any product but requires more space front and back, as shown in the images below
Both designs have powerful magnetic forces and are commonly used in the food and pharmaceutical industries.
They have a double row of magnetic rods which are offset for maximum effectiveness. However, they can also be specified with a single row of magnetic rods to suit the customer’s requirements.
This process means that the drawer does not have to be completely removed from the main housing, ensuring a safer and more efficient method of cleaning. This removes the risk of accidents and reduces cleaning operative downtime.
As an option, they can also be fitted with safety switches. Inlet and outlet connections are designed to suit our client requirements meaning additional adapters are not required.
TYPE A - DETAILS
This equipment is manufactured with rare-earth magnetic material, tested and certified to 12000 gauss on the contact surface.
This Magnetic Grid Box has a semi-automatic feature which makes the cleaning process of removing ferrous contamination from the magnetic rods both faster and easier due to the “scraper plate” design technology.
Once the safety nuts or stainless star knobs have been removed and the quick release clamps opened, the encased springs will automatically push the scraper plate forward to a set distance. From that point, the drawer can be pulled to the maximum distance, without fully removing it from the main housing. As the magnetic rods slide forward, the scraper plate traps the ferrous material which automatically falls into the catch chamber below. The catch chamber which has collected the metal contamination can then be easily removed, and the metal retained for analysis.
The 3D animation below demonstrates the cleaning process.
TYPE B - DETAILS
This equipment is manufactured with rare-earth magnetic material, tested and certified to 10000 gauss on the contact surface.
This Magnetic Grid Box has a semi-automatic feature which makes the cleaning process of removing ferrous contamination from the magnetic rods both faster and easier due to the sliding inner magnetic cores supported on side arms.
Once the safety nuts or stainless star knobs have been removed and the quick release clamps opened, the encased springs will automatically push the inner cores forward to a set distance. From that point, the drawer can be pulled to the maximum distance, without fully removing it from the main housing. As the inner magnetic cores slide out of the outer tubes, the ferrous material automatically falls into the catch chamber below. The catch chamber which has collected the metal contamination can then be easily removed, and the metal retained for analysis.
