don't old copier machines work off a similar principle?

this could go on and on, internet is full of this stuff.

Electro static filter to seperate plastic particles from metal particles.

Jim

where can I get this machine. you can talk a little more about this machine and its functions

Well, it has 2 rotating drums of non conductive material and two corona discharge electrodes. There is one drum above the other and the material feed down onto the first drum the static charge causes the plastics to stick to it, the metals are attacted but as soon as the touch they become like charged and are repelled off. there is 3 zones, metals, mixed (particles with metal and plastic) then plastic, the top drum is high voltage 20kv + this works better for larger particles

the bottome drumis fed from the middlings on the top drum and operates at a lower voltage 10-15kv to better seperate the smaller particles into the 3 zones stated above.


I do not know were to get this machine, that is why I want to build one.

I am setting up to start an electronics recycling business (part time) sometime this spring.

This is supposed to be able to concentrate metals from ground up pcb boards to metal by 90 percent.

this and a induction furnace are the last two pieces of equipment I am in need off.

Jim

the truth is very interesting to build this machine. I will seek more information for the construction.

I am buying at a low price all kinds of cards. and my idea is to make all processes and then sell the metal.

but in my country is very expensive light. you think that this machine is profitable in my country

thank you very much

I have the fellows in the residential HVAC department looking for a old hydrostatic filter, I think I could use the parts from it.

The first two boards are controllers from a UPS (Uninterruptable Power Supply, i.e. battery back-up system). I know this for a fact because I scrap lots of UPS'. The first is definitely from a small APC unit (400VA or smaller). The best part on them are the relays, which will have silver contact buttons. Small, but gather up enough of them and you got yourself a small pile of refinable silver. The rest is just base metal fodder: coils, transformers, aluminum heatsinks, etc.
