BJ Magnets’ Single or Double Housed Grid Magnets are a type of magnetic separator designed to capture and remove ferrous metal contaminants from dry or liquid materials. They can be placed directly in the product stream allowing free flowing products to come in direct contact with the grid. These Grid Magnets are typically constructed with 25 mm diameter magnetic rods or tubes mounted on 50 mm in a frame relatively and evenly from the centre to the edge. The length and width can be fabricated to any dimension, usually as per the client’s requirement.
BJ Magnets’ Grid Magnets offer excellent protection from metal contamination. As product flows over the magnetic tubes, captured metal contaminants are pushed to the underside of the tube where they are now out of contact with the product flow preventing wash off back into the clean material. Hence, cleaning is achieved by removing the Grid Magnet and wiping the magnetic tubes clean. It is important to keep in mind that by placing a Grid Magnet in the product flow, you will be reducing fifty percent of your flow through area. Therefore, Grid Magnets should be sized such that they do not impede the flow of product in any way.
Well-engineered, BJ Magnets’ Grid magnets provide a full range of ferrous metal separation from free-flowing products with gravity fall processing applications – Which are designed to offer maximum capture, control and protection of equipment while improving product purity. For maximum protection, they are located in critical areas where capture of ferrous related debris is not only possible, but most needed; and where removal of metals fragments for cleaning is feasible. Our Grid Magnets are most effective when the product is dry, free flowing and does not bridge between the magnetic rods or tubes. We select a Magnetic Grid at least twice the cross-sectional area of the incoming flow opening and discharge for better optimization.
PRODUCTS
BJ Magnets’ Grid magnets come in a series of magnetic rods or tubes arranged in a grid pattern with frames to sustain the housing that contains the magnetic grid. The flanges help to connect the housing to the existing inlet or/and outlet for easy installation in pipelines, chutes, or other equipment.
With key Features such as high-intensity magnetic field of up to 14,000 Gauss; the effective in capturing small metal particles down to 0.1 mm is guaranteed – which is suitable for use in various materials like powders, granules, liquids, etc. Our grid magnets come in either manual or Easy cleaning type, as well as in self-cleaning. They can also be customized in terms of size and magnetic strength to best suit your desired need.
BJ Magnets’ Grid magnets are an effective solution for ensuring product quality, in terms of reducing contamination risks, and protecting equipment from metal damage. Not only they are efficient in metal separation, they also reduced risk of equipment damage and improve product purity in enhancing food safety. They are easy to install and minimize downtime.
BJ Magnets’ Grid magnets are 316 stainless Steel produced in permanent Magnetic Grids with either manual or easy-cleaning; and in Electro-Magnetic Grids. These are also applicable for sanitary Grids in food and pharmaceutical industries. We make sure Magnetic field strength compile with the grid size and rods spacing. Suitable temperature range can be designed, to suit any pressure rating and flow rate capacity.
APPLICABLE REQUIREMENTS
BJ Magnets’ Grid Magnets are constructed with strong neodymium magnetic rods and can filter small ferrous contaminants from powders and granulates in free-fall and low-pressure transport pipes. The material of the shelf and the rods are in food grade stainless steel, which is pollution-free as well as corrosion-resistant. The surface is also mirror polished to meet the requirements of food or drug grade.
BJ Magnets’ Grid Magnets are useful in separation of ferrous contaminated material from raw materials. Typically used in Food, Pharmaceutical or Plastics industries. Sizes and configurations can be custom built to best suit individual requirements.
BJ Magnets’ Grid Magnets have standard working temperature of ≤80 ℃, but under special requirements, the maximum working temperature can reach 350 ℃.
Various designs are available in terms of magnetic field strength which can range from 5,000 to 14,000 Gauss; to guarantee a separation efficiency of 95% to 99.9% ferrous related metal removal.
Manufactured to fit various pipelines ranging from 50mm – 350mm diameter, our Housed Grid magnets come with flanges to suit square and round pipelines, for installation. The spaces between Magnetic Rods are determined based on your product specification; and the flow rate.
Applications are not limited only to: Flour, Spices, Grains, Maize, Salt, Animal feeds, Pellets (Feed or plastic), Sugar or Coffee. We provide high intensity Rare Earth magnets, which comes in nickel coated. Also available in ceramic either, if necessary, nevertheless.
- Ideal for free-flowing powders and granules. Very useful for food ingredients and plastics industries.
- Manufactured to food industry required grade standard, which is 316 stainless steel; with high effectiveness and consistent performance.
- Bespoke manufactured to your specific dimensions, hence in correspondence to your expected solution needs.
- The Magnet strength comes in high intensity Rare Earth magnets which can range from 7,000 to 14,000 gauss.
BJ Magnets’ housed Grid Magnets provide a full range of ferrous metal separation from free-flowing products with gravity fall processing applications. They are designed to offer maximum capture, control and protection of equipment while improving product purity.
Located at critical areas where ferrous particles capture is possible for maximum protection of food and equipment; removal of most cleaned debris is feasible. Cleaning is achieved by removing the Grid Magnet and wiping the magnetic tubes clean. It is important to keep in mind that by placing a Housed Grid Magnet in the product flow, you will be reducing fifty percent of your flow through area. BJ Magnets’ Housed Grid Magnets are sized such that they do not impede the flow of product stream.
BJ Magnets’ Housed Grids are mostly effective when the product is dry, free flowing and does not bridge between the magnetic tubes. Hence, it is crucial to select the Magnetic Grid at least twice the cross-sectional area of the incoming flow opening and discharge.
BJ Magnets’ Housed Grid Magnets Grid Magnets can be designed, manufactured and supplied on various optional types: Ordinary type which comes in manual cleaning, Easy-clean Type or Self-cleaning – taking into consideration shapes and sizes like: Rectangular Grid, Square Grid, Circular Grids, Centre-support style Grids (square/circular). etc…
BJ Magnets is ISO 9001:2015 certified company by SABS for Quality Management System. All our Magnetic Separator Equipment are designed, manufactured and supplied under observation of the principles of the HACCP International Food Safety Standard 0909MAGSEP 1-2010. Moreso, to the bargain of their effectiveness, the internal and external aspect of the magnetic equipment is produced according to the food health and safety standard in terms of the building materials; which is austenitic stainless steel of grade 304 or 316. Thereof upon completion, a certificate of Factory Acceptance Test (FAT) which is valid for 12 months is issued; in which case the equipment shall not be subjected to the anual validation.
