APPLICATION TECHNICAL MANUAL OF XINHAI MINING MACHINERY PRODUCTS XCIII Xinhai Hydrocyclone Principle Under the effect of pressure, pulp enters the shell through the square feeding pipe in involute direction, and does the rotary motion in the shell. The coarse or the dense particles get to the periphery of rotary current because of the centrifugal force and turns into riffling through the spigot; because of the smaller centrifugal force, the fine particles will be in the middle of the rotary current, move up along with flow, and finally become overflow being discharged from overflow pipe. XC Ⅲ hydrocyclone designed by Xinhai has achieved world advanced level. Because of the specially designed fishtail device out of the spigot and the specially designed siphoning installation on top of overflow box, it has good properties beyond other hydrocyclone. By adjusting the siphoning installation, we can acquire higher density of underflow and lower density of overflow. To silica sand industry, the overflow can even be water and the highest density of underflow reaches to 85%; besides, the fishtail device can keep the density of underflow stable though the feeding capacity, feeding density and feeding pressure change within certain limits. Features Adjusting the siphon device to control the fishtail and adjust the density of underflow; The special designed fishtail will keep a stable underflow discharge density when feeding volume, feeding density and feeding pressure vary under a certain range; 团 集 海 Prevent high overflow density.
