TWO:"You know very well where your brother is," Leona replied. "He is dead. He died in a house that is very close to here."In speaking of the mechanical knowledge to be gained, and of the privileges afforded for learners in engineering-works in a general way, it must, of course, be assumed that such works afford full facilities for learning some branch of work by the best practice and in the most thorough manner. Such establishments are, however, graded from the highest class, on the best branches of work, where a premium would be equitable, down [23] to the lowest class, performing only inferior branches of work, where there can be little if any advantage gained by serving an apprenticeship.

Hydrocyclone (liquid cyclone)01

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:The next morning I got up early, having been unable to sleep. I realised already that my task was difficult, dangerous, and full of responsibility, for I had to find out and communicate to the public the truth about events, which would be related as beautiful or horrid, according to the interests of my informants. It was dangerous, because I might meet with the same fate that seemed to have been inflicted on so many civilians already.
  • 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:
  • 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
