We manufacture separate covered magnetic grates primarily to order, according to the dimensions specified by the customer.
By installing a covered magnetic grid, you can prevent damage to downstream technological units, as the covered magnetic grid captures magnetic metal impurities that could damage these technologies. For example, cooling channels in cooled tools are damaged if metal impurities enter these channels. Sometimes the metal contaminants are so fine that they gradually settle in the channel until it is completely clogged. Screens and filter fabrics may be ineffective in some cases because the metal contaminants are in the micron range, which the separator reliably captures, but they pass through the screens and filter fabrics.
The presence of metal impurities in cooling emulsions can lead to a deterioration in machining quality (scratches, scrapes). The installation of covered grates leads to a very significant improvement in machining quality, and the surface quality of the resulting machined product improves greatly in a short period of time.
In other manufacturing industries, such as the ceramics industry, the quality of the final product can be impaired by the presence of black dots, which are sometimes so fine that they cannot be captured by filter fabrics and only become apparent on magnetic separators. The main advantage of this type of covered magnetic grate is that it can be placed in various inlet and outlet troughs thanks to its high resistance to moisture.
In addition to the quality of the final product, the installation of a covered grate also results in significant operating cost savings in relation to the grinding of cutting tools. After operational tests carried out at large multinational companies, where high financial sums are spent on grinding every month, the savings were demonstrably calculated at tens of percent.
The magnetic tubes of the covered grate are usually designed for a "grate" assembly and are made of 1.4301 / AISI 304 stainless steel as standard. If it is necessary to install covered magnetic grates in aggressive materials, we can supply a variant made of 1.4404 / AISI 316L material.
Thanks to the very thin wall of the cover tube, which is machined to a thickness of 0.6 mm, we achieve a very high magnetic force on its surface. The standard diameter of the cover tubes is up to 31.0 mm. The supporting elements of the magnetic tubes are normally made of flat materials with a thickness of 4 mm. Cover extensions are normally available in thicknesses from 2 to 3 mm.
Today, we exclusively use very strong permanent neodymium (NdFeB) magnets, which, thanks to their unique and currently strongest force among permanent magnets, guarantee reliable capture and, above all, subsequent retention (fixation) of metal impurities on the cover tube. Ferrite magnets, which were used in the past, are now rarely used for this type of separation.
These permanent neodymium magnets are inserted into a stainless steel cover tube. We currently offer 6 levels of magnetic induction, or magnetic force, which vary depending on the type of environment where the covered grate is located. Some levels have greater holding force, while others have a higher magnetic field value.
All materials are certified in accordance with EU standards.
All engineering work is performed on machines at our own production base using our own MAGSY CZ engineering technology.
Performed in accordance with the requirements of applicable technological standards for welding stainless steel materials. High output quality is guaranteed by rigorous output inspection of welds.
Magnetic cores are permanently secured and protected against moisture, even when cleaning these covered magnetic grates.
Custom manufacturing is our priority.
