An angle grinder, like any other power tool, consists of an electric motor, a gearbox and other working elements and assemblies. In the electric motor there is a non-ferrous metal – copper, which, in the event of a breakdown of an angle grinder, can be quickly removed with one’s own hands and returned to a scrap collection point. However, even in this simple case, there are certain nuances that you should be aware of when extracting non-ferrous metal (copper) from a crusher.
Materials and tools needed
Most often, during various works with the help of a grinder, the so-called anchor fails. It should be noted that this element of the electric motor somewhere in 20-25% consists of non-ferrous metals, namely copper. Thus, in the event of the anchor breaking, it can be dismantled (copper plating removed), then returned to the metal collection point.
This will require the following tools, which are likely to be in each person’s garage or home:
- A hammer.
- Ordinary chisel (instead of a chisel, you can use a chisel).
- Simple side cutters for the house.
It should be noted that the copper wiring contained in the anchor is often filled with a special varnish by the manufacturer. It is for this reason that it can be extremely difficult and difficult to disassemble it directly from the core. However, if this is not done, then at the scrap collection point all delivered copper will be accepted with a discount on the so-called blockage. Therefore, it is recommended that before sending to the ferrous and non-ferrous metal collection point, dismantle the anchor and remove the clean copper wire.
How to disassemble the anchor crusher for copper mining
To remove the copper wire from the anchor, you must first remove the applied varnish layer. To do this, you need to place the defective, disassembled anchor from the angle grinder in a fire or place it on hot coals. Then, after 15 minutes, it should be removed and placed in a container with clean water.
After performing this procedure, the copper wire will acquire a reddish tint, and the core will have a slight play on the axis (it will begin to hang down a little and will not be fixed as rigidly as before). If the plan is to simply put the non-ferrous metal back into pieces at a metal receiving point, the wire can simply be cut from the core side using wire cutters and then dismantled using pliers . However, if you need to get a whole piece of copper wire, it must be carefully unwound.
After that, the anchor must be properly clamped in a vice. Then you need to take a hammer and chisel (instead of a chisel, you can use a sharp chisel) and knock out all non-ferrous metal contacts from the anchor. As a rule, this procedure does not take much time, and 1-2 strong blows with a hammer are enough to dismantle a contact.
It should be noted that during the course of this procedure for the dismantling of non-ferrous metals, it is recommended to take care of personal protective equipment (wear gloves and glasses). Thanks to this method of dismantling copper from the anchor, you can get clean scrap, in which there are no various blockages that reduce its cost on acceptance.
