Self Cleaning Magnetic Grill

Product Description

Self cleaning Drawer Type Permanent Magnetic grill are used for the separation of iron particles from dry, granular or free-flowing products/materials. Drawer Magnetic Grills are made by using stainless steel having (Round or square or rectangular) with magnetic rods mounted on the drawer.

The Drawer Type grills are made up of magnetic elements, which are fitted in a drawer and are moved in a housing. Magnetic Elements are made up of 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.

High-Intensity Magnetic Grill having Gauss value of approximately 11,000 Gauss are employed at locations where the separation of contamination particles as small as 1 micron is required. These grills have been designed to attract super fine particles from the carrier material.

The Magnetic grill is supplied with the pneumatic cylinders, FRL Unit & Timer with Operating button for controlling the cleaning.

Cleaning Operation

• Start: After manually or electrically actuating the solenoid, the cylinders retract, pulling the magnetic tubes through the stripper assembly to deposit the collected tramp iron outside of the product flow area
• Finish: The cylinders return to the run position, pushing the magnetic tubes back into the housing (working position)
