TWO:"We did not stay long in Pekin after we got back from the Great Wall, as we had to catch the steamer at Tien-tsin. Here we are steaming down the coast, and having a jolly time. We are on the same ship that took us up from Shanghai, and so we feel almost as if we had got home again. But we are aware that home is yet a long way off, and we have many a mile between us and the friends of whom we think so often."It was certainly very odd. The doctor was so struck by something altogether wrong about the figure, something so suggestive of a pathological phenomenon, that he almost forgot his annoyance and remained watching it with an unlighted cigarette between his lips.

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:An hour of avowal could not have told me more; could not have filled me half so full of sympathy, admiration and love, as did that one slight motion. It befitted the day, a day outwardly so quiescent, yet in which so much was going on. A realization of this quiet activity kept us silent until we had come through the woods-pasture to its southern border, and so through the big white field-gate into the public road; now we turned up toward the grove-gate, and here I spoke again. "Do you still think we ought to wait here for the command?"
  • 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:The Doctor dropped his cigarette on the plate before him and grasped the edges of the table. His eyes were riveted upon that ghastly spectacle of transmutation.
