TWO:Meantime it seemed as if in spite of his absorption in his new family he was not to be entirely cut off from the old. In the summer of '87, just after the Jubilee, he had a letter from Richard, announcing that he and his wife were coming for a week or so to Rye. Reuben had not heard of Richard for some years, and had not seen him since he left Odiam��he had been asked to the wedding, but had refused to go. Now Richard expressed[Pg 390] the hope that he would soon see his father. His was a nature that mellows and softens in prosperity, and though he had not forgotten the miseries of his youth, he was too happy to let them stand between him and Reuben now that they were only memories.The next moment there was a bang, and Ditch's gun scattered duck-shot into the crowd. Men yelled, fought, struggled, stumbled about with their arms over their faces. For a moment nothing but panic moved them, but the next rage took its place. A volley of stones answered the gun, which being an old one and requiring careful loading, could not be brought into action again for some minutes.

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:Rate, skate, and crabs.

• 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:"O why when we loved like the swallows in April,

• 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
• Removal of fine particles from low-temperature solutions
