The Drawer Type grills are made up of magnetic elements, which are fitted in a drawer and is moving in a housing. Magnetic Elements are made up of hard ferrite ceramic magnets or high intensity rare earth magnets ( Ndfeb ). All the components are made up of Stainless Steel 304/316 material. The overall construction of the magnetic grills can also be made as per the customer specification and sizes
The grills are efficiently utilized if contamination is within 1% to 1.5% by weight. For higher levels of contamination Drawer Grills or Multi Drawer Grills should be used.
Low Intensity Magnetic Grill having Gauss value of approximately 2,500 Gauss are ideal for trapping contamination such as Nuts, Bolts, Screws, broken washers etc. these grills are designed to attract larger iron pieces from relatively larger distance.
Medium Intensity Magnetic Grill having Gauss value of approximately 5,500 Gauss are used where the contamination is in particle form, however there may or may not be continuous flow of material to be separated. The contamination size may be as low as 150 microns but not lower than that. The material should be free flowing and non sticky.
High Intensity Magnetic Grill having Gauss value of approximately 10,000 Gauss are employed at locations where separation of contamination particles as small as 1 microns is required. These grills have been designed to attract super fine particles from the carrier material.
In all the three classes of grill, it is a necessity to clean the grills at regular intervals. It is recommended to clean the grill thoroughly before every pass (or as scheduled as per users requirement and experience). More accumulation of Iron particles for long time will reduce the effectiveness of the grill. For highest attraction, the grill needs to be fully clean.
