Relations between crusher and flotation equipment
已有 204 次阅读 2012-03-29 16:53 标签: equipment crusher betweenThe vibrating equipment is an efficient new, multi-layer vibration equipment
for stone quarries and sand filters can also be used as classification
processing, building materials, electricity, coal, the role of chemical industry
products, with the sound vibration of a small, reliable structure, high
efficiency, durable, safe and convenient features.
The feed water to the DAF
float tank is often (but not always) dosed with a coagulant (such as ferric
chloride or aluminum sulfate) to flocculate the suspended matter.
Dissolved
air flotation is very widely used in treating the industrial wastewater
effluents from oil refineries, petrochemical and chemical plants, natural gas
processing plants, paper mills, general water treatment and similar industrial
facilities. A very similar process known as induced gas flotation is also used
for wastewater treatment. Froth flotation is commonly used in the processing of
mineral ores.
A portion of the clarified effluent water leaving the DAF tank
is pumped into a small pressure vessel (called the air drum) into which
compressed air is also introduced. This results in saturating the pressurized
effluent water with air. The air- saturated water stream is recycled to the
front of the float tank and flows through a pressure reduction valve just as it
enters the front of the float tank, which results in the air being released in
the form of tiny bubbles. The bubbles adhere to the suspended matter, causing
the suspended matter to float to the surface and form a froth layer which is
then removed by a skimmer. The froth-free water exits the float tank as the
clarified effluent from the DAF unit.
Some DAF unit designs utilize parallel
plate packing material, lamellas, to provide more separation surface and
therefore to enhance the separation efficiency of the unit.
Vibrating feeder
can feed block or granule materials from the material storage to charging device
evenly and continuously. It can realize even feeding for crushers in sandstone production line and
make rough screening for materials. Widely applied in combined operation of
crushing and screening in the industries like metallurgy, mine, mine ion,
building materials, chemicals, etc.
DAF can be categorized by Circular (more
efficient) and Rectangular (more residence time). The former type requires just
3 minutes and the example is Wockoliver DAF system, whereas Rectangular requires
20 to 30 minutes the typical example can be syskill DAF system. One of the
bigger advantage of Circular is its Spiral Scoop.
With its high quality products such as Sand making machine, Impact crusher, Rock cone crusher, Sand maker, Dryer machine, Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
