Magnetic grate are widely used in food processing industries such as dairy products, fruit juices, sauces, and syrups.They form a magnetic field by installing high-strength magnetic rods inside the fluid pipeline, which can effectively adsorb metal contaminants such as iron filings and iron powder, achieving the effect of removing ferromagnetic impurities in liquid or paste foods. They can prevent metal impurities from entering the final product, prevent equipment wear, and ensure the purity of the product and food safety.

FAQ
Q1: What is the difference between single-layer and multi-layer magnetic grate?
Single layer: Suitable for low iron impurity content, simple working condition, low budget.
Double / triple staggered layers: Material passes through multiple magnetic fields, higher iron removal efficiency, recommended for high-purity production requirements.
Q2: Can you customize non-standard size magnetic grate?
All width, length, magnetic bar quantity, layers and magnet strength can be customized.
Q3: What housing material should I choose, SS304 or SS316L?
SS304: Cost-effective for ordinary mineral, plastic raw materials. SS316L: Anti-corrosion, suitable for food, pharmaceutical, slightly corrosive powder environment.
