TWO:In the afternooncalm and almost coolI went to call on the Resident, who talked to me of India in the days of Dupleix, of its departed glory, and the poor old fort of Chandernagore, once impregnable and now demolished under the provisions of treaties; and as we walked on through the town, between gardens that look like the great parks of the French kings, all the past seemed to live again on this forgotten spot of earth, and every moment, in the silence of the purple dusk, I could have fancied that I saw in the avenues, under the tall ph?nix palms, the shades of powdered marquises in skirts with full farthingales, and of gallant knights of St. Louis; then from a far distance came the sound of a pianosome simple melody quavering in the air that was so full of memories.

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:Spread before us in the iridescent atmosphere, the view extends over Palitana under its blue veil of light smoke, over the verdant plain chequered with plots of brown earth, and the winding ribbon of the Satrunji, a river as sacred to the Ja?ns as the Ganges is to the Brahmins. And far away, vague in the distance, a light shimmering more brightly where all is bright, lies the luminous breadth of the sea.
  • 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:A stone parapet runs along the river road, and below it the grassy bank slopes gently to the clear and limpid stream of the Ganges. On the shores[Pg 141] of the sacred river fine trees overshadow many idols, and fresh flowers are constantly laid at their feet.
