The whole production process of cement can be summarized as 'two grinding one
burn', the' burn' refers to that the raw materials after ground and well
confected will be firing to clinker under high temperature of the .
Henan hongxing will tell the details of the feeding procedure of :
Tell the site inspector stop the kiln slow rotating and separate
the kiln from slow turning clutch, set the kiln at a speed of 0.4 ~ 0.5rpm and
then start the kiln motor;The Rotary kiln as one of the main drying equipment,
its usage is very wide: building material, metallurgy, chemical, environmental
protection and many other production industry。 It is also widely used for
turning round of solid materials machinery, physical or chemical processing。 The
rotary kiln can be used to burn the cement forging outside, it can still be used
to forge the clay, limestone and slag drying, etc。
Close the entrance baffle
of the high temperature fan, set the speed at 200rpm, start the main motor. When
the fan runs smooth, you can gradually open the fan entrance baffle. And adjust
the rotating speed of the fan based on the outlet pressure of pre-heater;
Fire-proof material production, the rotary kiln forging the raw material, make
its size stability, increase strength, then proses molding。Non-ferrous and black
metallurgy, iron, aluminum, copper, zinc, tin, nickel, tungsten, chromium, file
metal, which can be used in smelting equipment in rotary kiln of minerals,
concentrate, intermediate objects of sintering, roasting。
The first feeding
of the rotary kiln should be 100t / h; When feeding, the wind, material, coal
changes greatly. You should notify the site inspector roll levels of flap valve
to ensure the feeding smooth; The Rotary kiln under the action of raw materials
in the friction with the wall together rises slowly, when it was turned to a
certain height。 The horizon of raw material surface layer is equal to the
viewpoint of the formation of the accumulation of raw material, the raw
materials particles falls because of gravity, it slides along the material
layer。
Notify the raw material system adjust the outlet fan baffle opening of
the electric dust and ensure outlet negative pressure of the exhaust fan about -
150 ~ - 300Pa. And spray water when the kiln exhaust fan outlet temperature
reached 190~200 degrees;
When the feeding stable, inform the site stop diesel
pumps and extract the oil gun.
The above main points provided by our technicians, Hongxing Rotary kiln has the characteristics of large output, low energy consumption, good effect, which can bring more benefits to you .
