Metal Detection and Separation Systems
Quarry and mines
Expensive crushing equipment can be damaged by tramp metal which can be anything from digger teeth to crusher or other plant parts. Traditionally magnets of varying type and strength would be installed to remove ferrous type metals.
However some types of tramp metal due to material composition or position in the material load can bypass the magnets and damage equipment.
Metal detectors detect all metals and will stop the conveying equipment to ensure proper protection of the equipment.
Metal detectors are designed to specifically meet the requirements of the particular quarry or mine application.
Most metal detectors are located under the conveyor belt and provide protection from regular sized tramp metal. However where greater sensitivity is required, the metal detector search coils can be located above and below the belt.
There are different types and configurations of metal detectors to suit all applications
Metal detectors and separators are used in the plastics industry from machinery protection to final product quality control.
Due to raw materials being a mix of virgin and regrind material metal ingress is a rising problem which can damage the product or block injection moulding gates or damage expensive granulator blades.
Eriez provide metal separators that effectively separate tramp metal from free flow plastic raw material in either gravity fed or pressure conveyors.
Food and Pharmaceuticals
Metal contamination represents one of the most common forms of foreign body contamination in food and pharmaceutical products. In order to reduce the occurrence of metal as a hazard various control measures need to be implemented including magnetic separation, metal detection and separation systems.
Magnetic Separators used in the food industry are invariably powered by permanent magnets of varying strength. The introduction of ‘Rare Earth’ Permanent Magnets, which produce twenty times the magnetic power of conventional ‘Ceramic’ magnets, have extended the use of Magnetic Separators to the removal of very small particles of iron as well as rust, scale and other fine particles.
Metal Detectors and metal separators compliment the installation of Magnetic Separators as they can detect non-ferrous metal, which magnets are unable to remove.
The purchase of a metal detection system can represent a significant capital investment for many companies, so it’s important that the equipment is reliable, of appropriate design for the intended application, and used in the most effective way. This will ensure a good return on investment through decreasing costs and maximising product safety.
We provide a comprehensive range of detectors for the industry including the leading Aperture metal detectors, Gravity metal separators and Pipeline metal separators.
