Detailed Product Description

What Break-day serves 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.
Main features: 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.
