Environmental problem of ultra-fine grinding is dust and noise pollution during wet grinding.
Dust problem in the ultra-fine grinding in the dry, more or less dust
problems, feeding port, discharge port and the fan seal, due to fine particle
size, the dust can easily fly from place to seal well. Solution approach is to
maximize the use of negative pressure system, with a good seal and fine grading
equipment, crushing equipment, if necessary, installation of dust removal system
in the crushing plant to ensure clean production workshop, which pigments, dyes,
fiber and toxic powder Powder is extremely important.
Ultra-fine grinding
equipment, there are some vibration and noise, especially for vibration mill,
ball mill, the noise up to 120dB, if necessary, set the isolation tank or a
special isolation room, isolating powder equipment has now developed a number of
ultra low-noise grinding equipment, such as the tower mill, mixing mill, etc.
can be given priority, but the ultra-fine grinding bad environment, not the same
requirements in different industries, mining, refractories, coal industry and
other industries, the relatively poor condition and In the pharmaceutical and
food industries need to clean. In any case, noise reduction is imperative.
Wet ultrafine grinding, no matter what kind of technology, especially the
fine ceramics, powder metallurgy, inorganic non-metallic materials industry, the
application of water, oil or alcohol can be recycled, which requires the
dehydration of water or To filter the oil, in the case of raw materials to
ensure no contamination can cycle applications.
Ultra-fine grinding of many
industrial production of a unit operation, environmental issues should be
specific to each industrial production into account.
As the limestone is
brittle, easily crushed, not only the force is split in the crush machine. drop
in the transport process is also due to unloading and storage wall ore, ore and
ore between the collision crushed ore grinding edges, ore powder generated for
pre-screening is not located, a large transport operation of the crushing
process is poor, over-grinding phenomenon is particularly serious, such as the
original limestone JISCO Xigou process, the port of discharge of coarse broken
120-130mm, the breaking of discharge port for the 57-60mm, the crude products
are all broken into in the case of breaking, breaking products in more than 6%
of 0-30mm powder ore. The analysis, which is 6% of the fine ore in the limestone
crushing and breaking machine produced by squeezing each other, and with the
saving good.
To prevent the powder too much phenomenon, must take the
following measures in the broken process and production
management.
With its high quality products such as 、、、Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
