Salt mining , transfer and stockyard system equipment of a salt plant of TECHNO group in the Middle East

We got an inquiry from a salt plant of TECHNO group of Jodan. The company is located at 63 King Faysal Bin Abdul Azeez St.Amman - Jordan. They request us to make a plan for their salt plant from salt mining to storage. Our plan was as follow, by using an bucket wheel excavator to mine the salt, and transfer them to stockyard by conveyor belt and stacker. At the begining we are in good relationship, once they got our plan drawing and commercial offer, they disappeared and no longer to reply our email or answer any question, we have no idea what is they real purpose. Hope all our friends pay attention to this.
