Description
High
Pressure suspension grinding mill is an improved
type of Raymond mill. The purpose of the this kind mill is to grind
non-flammable and non-explosive materials in the fields of building
materials, mining, metallurgies and chemical industry with hardness
less than 9.3 in Mohs scale and humidity less than 6 percent.
Examples of the materials are: quartz, feldspar, barite, fluorite,
dolomite, garnet, bauxite, zircon, marble, calcite, iron ore, rock
phosphate, coal, slag and so on(400 kinds of material). The
granularity of the final products can be changed from 30 to 425
meshes
Features
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.
Working
Principle
General:Crushing -- Grinding -- Selecting -- Collecting
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 action 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
and fineness.
Technical features of YGM high pressure
suspension grinding mill:
1. High-efficiency: the full use of the
jet-flow and optimized impeller structure can greatly improve the
crushing and grading efficiency, thus greatly improving the
production.
2. High grading degree: with the frequency
conversion and grading adjustment technology, the YGM high pressure
suspension grinding mill have stable and complete grading system
and the special sealing measure ,which can efficiently prevent the
leaking of the fine particles .And the particle size can reach
500—6000monyh and the thinnest can reach
12000monyh.
3. Low wearing: the crushing wearing parts and
the impeller of the Raymond mill mainly adopts German technology.
And with the optimized design of the inner cavity structure and
anti-abrasion and allergy materials, the YGM high pressure
suspension grinding mill has made the lowest wearing parts
and the highest purity.
YGM high pressure suspension grinding mill
working principle:
Firstly, raw material is crushed by jaw crusher
to the size required, and then the crushed materials are elevated
into a hopper from which the material is transported through the
electro-magnetic vibrating feeder evenly and continuously into the
grinding chamber for powder-processing. The rollers of Raymond mill
oscillate outward to press the ring because of the centrifugal
force and the shovel scoops up the materials, send to the middle
between ring and roller to accomplish the grind. After this, the
ground stuff is carried by the air from the blower into the
separator for screening. The fine powers are blow into the cyclone
collector and are poured out through the output-powder valve as the
final products and the rough stuff after the screening will be
recycled back into the grinding chamber for regrinding. The airflow
system is closely sealed up and circulated under condition of
negative and positive pressure.
Raw materials: quartz, feldspar, barite, calcite
carbonate, limestone, talc, ceramic, iron ore, carborundum,
bauxite, rock phosphate, coal and other materials, total about 400
kinds of materials
