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:From the church the prince was conducted, not back to his prison in the fortress, but to a town mansion, which was assigned as his residence. His sword was restored to him. But he was still not fully liberated. Officials, appointed by his father, surrounded him, who watched and reported all his movements. The first act of the young prince, upon reaching his apartment after this partial liberation, was to write as follows to his father. We give the letter as translated by Carlyle:In the month of October, 1747, Field-marshal Keith visited his Prussian majesty at Sans Souci. In a letter to his brother he thus describes the results of his observations:
  • 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:425 In these hours of trouble the noble Wilhelmina was as true to her brother as the magnet to the pole. She was appalled by no dangers, and roused all her energies to aid that brother, struggling, with the world arrayed against him. The king appreciated his sisters love. In a poetic epistle addressed to her, composed in these hours of adversity, he wrote:He seems ever to have treated his nominal wife, Queen Elizabeth, politely. For some months after the accession he was quite prominent in his public attentions to her. But these intervals of association grew gradually more rare, until after three or four years they ceased almost entirely.
