Problem with My new Tefal food chopper due prolonged use

Note dated 2014-10-17: Since 2014-09-19 , I have stopped using this Tefal food chopper and on 2014-10-17, I decided to stop using it forever. 

On 2014-09-19 at about 5.00 pm, part of the Tefal food chopper melt and dropped out while I ground my brown probably due to hear as the "tip" was very hot and due to the fact I ground the rice continuously for too long because the rice could not turn finer as I wanted.

I threw away the brown rice ground invade some "dropped paint" fell into the rice.
