MAGNETIC AND NON-FERROUS SEPARATOR FOR MINERALS AND LITHIUM BATTERY POWDER

The rotating magnetic separator is intended for the metal-free processing of lithium-ion powder for batteries. The automatic cleaning rotating magnetic separator filters metal particles as small as 30 µm from the poorly flowing lithium powder. The quality of cathode powders such as nickel, cadmium and lithium must be optimal to guarantee the operation of a battery. Any metal contamination present in the powder reduces the quality of the material mix and leads to a battery’s short life. Lithium is extracted from salt lakes such as the Salar de Atacama in Chile, where there are huge reserves of brine containing lithium. Some large producers process this lithium into a powder that serves as a raw material for batteries used in electric cars, laptops and mobile phones, among other things.

Operation
The magnetic separator contains nine strong, rotating magnetic bars that prevent the fine lithium or other powder from sticking to the bars like a bridge and which enables a good deferrization.  The contact with the magnetic bars is optimal. With a flux density of 12,000 gauss on the bars, the magnet can capture paramagnetic particles such as iron oxide and stainless steel in addition to iron particles. The magnetic separator is dust-proof and can be cleaned automatically. The valve box in the system removes the captured metal particles on site, as you can see in this video.

SMART NON-FERROUS SEPARATOR FOR COARSE MATERIALS LIKE ORE

The Eddy Current Non-Ferrous Separator removes non-ferrous metal particles, such as copper and aluminium from ore, for example. They are designed for the recovery, recycling or removal of metals in a continuous process. A new development is the IOT -Internet of Things– module; this makes the machine suitable for almost any product flow and requirement. The module sends all important data to a dashboard through the internet. This allows operators to see what the performance of a machine is at a glance. How fast is the rotor turning? How many vibrations are there at the moment? What is the belt speed? All these questions are displayed graphically and in real time. The internet connection also offers the option of remote assistance. The Goudsmit service team is available online to monitor, resolve any malfunctions, and carry out software updates. This saves a lot of time and therefore increases the up time of the Eddy Current Separator. The connection with Profinet also makes it possible to integrate a non-ferrous separator in a machine line. In this way, everything works together and the line can be controlled centrally.

Process
The increasing demand for batteries for laptops, telephones and electric cars, for example, is driving up the price of raw materials extractable from mines. This applies to substances such as nickel, cadmium and lithium – the cathode powders – as well as to anode powders such as graphite, carbon black or silica. Magnets play an important role in the final development of lithium batteries, both in the extraction and production phases. The quality of a lithium ion battery depends on the purity of the raw material. Magnets  and non-ferrous separators are also necessary for the recycling of such batteries.
