| Three-rings
and Medium-speed micro powder grinder |
HGM
series of three-rings and medium-speed micro powder grinder
is a new type of making micro powder machines through more than
twenties times research and improvement, depending on two decades
of hard work & experience and inputting the latest mechanical
techniques of Sweden. It is an incorporated one of the two countries
and a leader of the grinding industry nowadays. |
HGM
series of three-rings and medium-speed micro powder grinder is widely
used in making fine powder or micro powder, and the raw materials
should be non-inflammable and non-explosive under the Moh’s hardness
less than 6 grade such as limestone, calcite, dolomite, kaolin,
bentonite, talc, illite, pyrophillite, barite, meerschaum, fluorite,
potash ore, etc. The lifetime of spare parts is relied on the hardness
of raw materials, and is lowered once the Moh’s hardness is up to
4-6 grade. |

| The
mainframe through reducer makes the main shaft and all the turntables
rotating which lets the rollers and the ring rolling and rotating
with dowel pin. First the large ones of the materials is crushed
into small ones by the hammer crusher and the later is transmitted
into the hopper by elevator, then the vibrating feeder sends the
materials onto the middle of the upper turntable in a stable and
well-proportioned way, which are separated under the centrifugal
force and fall into the raceway where they are crushed, grinded,
rolled. Through the first process, enter into the second turntable
then the third one。Hyper centrifuger indrafts the air inside and
carries the larger powder into the electing powder machine. The
vortex made by rotating turbine of the electing powder machine lets
the larger ones recycled back into the grinding chamber for regrinding,
then smaller ones enter into the cyclone collector and final products
are discharged by the discharge valve, airflow with little fine
dust is refined by pulse dust catcher and discharged through the
blower and the muffler. |
| 1.
High efficiency and lower consumption. In the condition of the same
material, power and the fineness, its capacity is increased by 40%
compared to the jet mill and the mixing grinder.
2. Longevity. In the condition of the same power and the fineness,
the spare parts have a longer lifetime, usually more than one year,
to the shaft impactor crusher and the turbine crusher.
3. Non-Bearings and non-bolt in the grinding chamber. Because of
this, these questions destroying the machines can never exist for
bearing, sealing element or the bolts loose.
4.The fineness of final products can add up to 5μm, and screening
rate is 97%。 |
