TWO:Entering by one of the fourteen gates in the ramparts of stone blocks scarcely hewn into shape, the city of palaces and mosques is found in ruins, matching the fortifications, without any decoration,[Pg 225] and all of the same cold grey hue, like a city of prisons.Then starting to his feet, and stretching out his arm to point at me, he poured forth invective in sharp, rapid speech. The words flowed without pause:

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:A vision of Europe. Cottages surrounded by lawns under the shade of tall trees, and against the green the scarlet coats of English soldiers walking about. And close about the houses, as if dropped there by chance, tombs covered with flagstones and enclosed by railings, and on all the same date, June or July, 1857. Further away, under the trees, are heaps of stones and bricks, the ruins of mosques and forts, hardly visible now amid the roots and briars that look like the flowery thickets of a park, varied by knolls to break the monotony of the level sward. In the native town that has grown up on the site of the palace of Nana Sahib, built indeed of the[Pg 186] ruins of its departed splendour, dwell a swarm of pariahs, who dry their rags and hang out clothes and reed screens over every opening, living there without either doors or windows, in utter indifference to the passer-by.
  • 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:Wide strands of golden sand; here and there among the rice-fields the palms and bamboos are less crowded. In the moist air, that grows hotter and hotter, the daylight is blinding, hardly tolerable through the blue glass of the windows. Scorched, russet rocks stand up from the short grass, tremulous in the noontide heat. The cattle, the very birds, silent and motionless, have sought shelter in the shade; all the people have gone within doors. And then, towards evening, in an oasis of gigantic trees, amid bamboos and feathery reeds, behold the huge temples of Madura, in sharp outline against a rosy sky.
