Magnetic plate installation above the belt conveyor – assembling instructions
A benefit of our magnetic plates consists in an easy assembling on a place of separation. For that, four hanging meshes are used, each in one of the plate corners. Magnetic plate should be located as close as possible to the separated material, keeping the air gap needed for the metal impurities already separated. This prevents their catching and tearing off by the material transported on the belt.
To increase the separation efficiency, it is suitable to open the conveyor belt on the assembling place, to achieve a thinner separated material layer, and spread it out within the entire belt width. At the same time we recommend to install the magnetic plate between the cylindrical stools, on the place with the lowest occurrence of other steel structures or, possibly, to replace a part of the conveyor structure within the nearest separator proximity with stainless steel or other non-magnetic structural elements.
Magnetic plate above the belt conveyor – design and functioning
Magnetic plates above the belt conveyors are manufactured with the standard dimensions according to the type series of conveyor belt widths. Mostly they are equipped with ferrite magnets whereas we distinguish between the three general variants according to the thickness needed for a required separation efficiency:
- ECO – the thickness of 205 mm for a separation of large and medium size ferromagnetic impurities from easily permeable materials transported with a lower speed and in a thinner layer.
- STANDARD – the thickness of 230 mm finds its application area in most of the situations where the maximum recommended speed of the transported material is achieved.
- ES (extra strong) – the thickness of 300 mm for using in demanding conditions where there is a harder material permeability or where the material is transported in a thicker layer and, at the same time, separation of smaller metal impurities is required.
In rare situations we supply the magnetic plates equipped with neodymium (NdFeB) magnets with the thicknesses of 45 mm (STANDARD) and 60 mm (ES-extra strong). Except the low weight, their another advantage consists in an enormously strong magnetic field enabling a separation of even small and very small ferromagnetic impurities. However, this benefit (in comparison with ferrite plates) is limited by the installation condition of the maximum 100 mm distance from the conveyor belt surface.
The design of MAGSY magnetic plates is adapted to the industrial use, and a special magnetic circuit with a shadowing steel plate eliminate magnetic field radiation to its surrounding and it concentrates the radiation in a direction of the conveyor belt with a transported material.
Magnetic plate cleaning is performed manually, always during technological break, on a stopped belt conveyor. For an easier removal of smaller ferromagnetic impurities, it is possible to equip the plate with a special cleaning sheet metal with handles that will accelerate the whole cleaning process. Caught impurity quantity has an impact on further separation efficiency, so we recommend to adapt the cleaning frequency to the quantity of ferromagnetic impurities caught.
