TWO:And all that I have been relating to you is due to the king alone, who not only gave the orders, but himself saw that they were faithfully obeyed. He both conceived the designs and executed them. He spared neither care, nor trouble, nor vast treasures, nor promises, nor recompenses, in order to assure the existence and the comfort of half a million of rational beings, who owe to him alone their happiness. There is something in my mind so heroic in the generous and laborious manner in which the king has devoted himself to the restoring to this deserted country its population, fertility, and happiness, that I think you will see his conduct in the same light as I do when you are made acquainted with the circumstances.

Hydrocyclone (liquid cyclone)02

A hydrocyclone (liquid cyclone) injects treatment solution into stationary equipment to perform separation, classification, and concentration, and is an innovative separator with a very simple structure and no drive unit.

Structure of a hydrocyclone (liquid cyclone)

A suspension containing fine particles of several micrometers or more is supplied to a cylindrical container circumferentially at high speed. And as a result it starts to rotate and a centrifugal force is generated. At this time a gravitational acceleration of several tens of thousands of G is generated in the circumferential direction, and thus leading to fast sedimentation and concentration of the fine particles. The separated concentration can be freely selected by changing the supply rate (supply pressure and flow rate) and the flow ratio of the outlet. Our hydrocyclone (liquid cyclone) was designed and manufactured to classify and concentrate fine particles, and so has a small element.

THREE:280 Yes, I say, the king rejoined. That is my answer, and I will never give any other.
  • Equipment costs can be reduced.
  • Operating costs can be reduced.
  • Maintenance costs can be reduced.
  • Any change in raw material and product can be easily addressed.
  • Large amounts can be treated in a small area.
  • Separation and cleaning are easy because of the simple structure.
  • Simplified control
  • This equipment can be operated in synchronization with external devices.
  • Alarm and interlock mechanism.
THREE:In a letter to his friend Lord Marischal, dated Dresden, November 23, 1758, just after the retreat of Daun into Bohemia from Saxony, Frederick writes sadly,The king and Voltaire soon became involved in a very serious quarrel. Voltaire had employed a Jew, by the name of Hirsch, to engage fraudulently in speculating in the funds. The transaction was so complicated that few of our readers would have the patience to follow an attempt at its disentanglement. Voltaire and his agent quarreled. The contention rang through all the court circles, as other conspicuous names were involved in the meshes of the intrigue. A lawsuit ensued, which created excitement almost inconceivable. The recent law reform caused the process to be pushed very rapidly to its conclusion. Voltaire emerged from the suit with his character sadly maimed. He was clearly convicted of both falsehood and forgery. The king, annoyed by the clamor, retired from Berlin to Sans Souci. Voltaire was not invited to accompany him, but was left in the Berlin palace. In a letter which Frederick wrote to DArget, dated April, 1752, he says:
  • Classification and concentration for the manufacture of inorganic powder materials
  • Classification of ceramic materials
  • Removal of fine particles, including iron powder
  • Removal of fine particles from pigments
  • Removal of fine organic particles from solvents
  • Separation of starch and yeast
  • Removal of fine particles from high-temperature strong acid solutions
  • Removal of fine particles from low-temperature solutions
