The Dingbo Three-ring Micro Powder Mill(ultrafine mill) is for
super-fine grinding materials with hardness less than 6 in Moh’s
scale and humidity less than 6 percent such as kaolin, limestone,
calcite, marble,talcum, barite, gypsum, dolomite, bentonite
mud,mica, pyrophyllite, sepiolite, diatomite, graphite, alunite,
fluorite, potassium feldspar, phosphorite, pigment and so on. The
granularity of the end products is 325-2500 meshes
General: Crushing -- Grinding -- Selecting -->
Detailed: The High-pressure Suspension Mill has the same working
principle as Raymond Mill, but its grinding fitting is furnished
with 1000 - 1500 kg pressure spring.
When the machine works, the grinding roll, under the aaction of
high pressure spring and centrifugal force, rolls close up to
grinding ring, its rolling pressure ratio is 1.2 times of Raymond
mill given an identical condition, and its output may increase 10%
to 20%Please note that when the grinding roller and grinding ring
reach a certain degree of abrasion, please adjust the length of
high-pressure spring to keep the constant grinding pressure between
grinding roller and grinding ring, so as to ensure a stable output
1. Higher output. Its output increases by 10%-20% comparing with
Raymond mill under the same power condition.
2. Larger range of final fineness. Size of final product can be
0.613mm (30mesh) 0.033mm (425mesh). Some can reach the fineness of
0.013mm (1000 mesh).
3.Good dust control. High Pressure Suspension Mill meets the
requirement of national dust-dump standard.
4.Easy to operate. The whole system is combined by some independent
systems, and the cohesion between the systems is good.
5. Excellent sealing. The multi-class seals are adopted to keep the
grinding equipment tight closed.
