6. HC Series Roller Mill
Upgrade New Version for Traditional Raymond Mill

7. Current Application State of Traditional Raymond mill
Currently, Raymond Mill(Roller) is mainly used for dry grinding of Non-metallic
materials (80-600 mesh)
The original system configuration of these devices caused following deficiencies:
1. low efficiency, high energy consumption, high dust emissions.
2. Strong vibration for main frame, loud noise, high maintenance rate.
3. Temperature in main frame cavity is hard to control, hard to discharge impurities.
Technical problems that has to be solved for non-
metallic material processing - how to achieve high
efficiency and energy saving environmentally friendly
production?

8. HC Series Roller Mill
HC-series Grinding Mill is a kind of newly-designed roller-type
mill, featuring in higher efficiency, lower power consumption
and much better performance than traditional raymond mill.
This mill is widely used to grind any non-metallic minerals
with Mohs hardness below 7 and moisture below 6%, such as
limestone, calcite, activated carbon, talc, dolomite, titanium
dioxide, quartz, bauxite, marble, feldspar, barite, fluorite,
gypsum, ilmenite, phosphorite, clay, graphite, kaolin, diabase,
gangue, wollastonite, quick lime, silicon carbide，bentonite,
manganese. The fineness can be adjusted from 0.18mm(80
mesh) to 0.022mm(600 mesh), whose range is much wider
than that of traditional Raymond mill. HC1700 grinding mill is
the first large Raymond mill in China, comparing to the
traditional mill (5R Raymond mill), its capacity is about 2.5 to
4 times higher. The output of the largest model-HC3000 can
reach 90t/h, which is specially suitable for large scale powder-
making projects for effectively increasing the production
capacity while reducing the power consumption.

9. Technology Updating of HC Serial Pendulum Grinding Mill
Updating --- R serial → HC1300 → HC1500 → HC1700 → HC1900 → HC2000 → HC3000
HC Series Large-scale Pendulum Grinding Mill fills the gaps of domestic large-scale
pendulum grinding mill market and solves the problem of large-scale production
which traditional Raymond Mill can not achieve. It expands the application fields of
Pendulum Grinding mill and greatly improves the equipment performance both in
production and the unit energy consumption.

12. Technical Advantages
HC series grinding mill is researched and designed independently by our R&D experts. It is
distinctly superior in the following respects.
1. Unique swag style (Patent No: CN200720081221.1)
The traditional R-type roller device caused a skew angle between roller and ring working
platform because the rollers are placed horizontally and roller device turn up when swag.
And the HC1700 applied vertical roller device which throw away horizontal when swag. The
centrifugal force of vertical device increased almost 35% when the central rollers of main
mill swag so that the roller compaction and crush power are strength. Otherwise, it is better
for powder crush and average wearing of grinding area because of the horizontal touch of
roller and ring of the vertical device. At the end, to extend the service life of wearing parts.

13. Technical Advantages
2. Turbine Classifying System（Patent
No.ZL201030143470.6）
The classifying system uses the turbine
classifier featuring in higher production
capacity and more efficient classifying,
which can make powder with a precise
fineness ranging enlarge from 80-
200mesh to 80-400mesh and ensure
the highest passing rate.
3. Multi-layer blocking sealing structure (Patent No.CN200820113450.1）
The roll assembly works in high dust concentration environment. The lamination sealing of
the traditional R type roller mill sealed bearings unreliable. While this proposal adopted
with multi-layer blocking sealing structure which combined with the floating oil sealing
technology, screw seals and skeleton seals to prevent dust going into the bearing. Keep the
roll assembly working smoothly and durable. Vastly short the maintenance time.The
traditional R type roller millneeds lubrication each days. The newly designed sealing
structure ensures the roller assembly works continuously for 500-800 hrs without
lubrication.

14. Technical Advantages
4. PLC Full Frequency Converting Control System:
By increasing the cost of investment, the motors of main mill, blower, classifier and belt
feeder can all be selected to have frequency converting control. The PLC interface operation
can realize full-automatic producing and unmanned operation, which will largely reduce the
labor cost. The PLC system will simplified the control and operation mode, serial operating
can be realized, control speed can also be improved. Moreover, the alternating-current
converter has outstanding adjust performance and energy saving effect. The frequency
converter of the facility plays an important role in facility control, energy saving and easy
maintenance.

15. Technical Advantages
5. Small vibration amplitude, lower error rate to ensure the sustainable produce: the
vibration reduce shaft sleeve is made of special rubber and wearable material which is
alternative according to client’s actual demand, not only to isolate the vibration caused by
equipment running efficiently, but also extend service life and avoid frequent maintenance,
ensuring persistence processing. It is a breakthrough in addressing the issue of short
service life and frequency maintenance of traditional Raymond mill.
6. The Inblock Casting Foundation Base: it provides solid structure and perfect vibration
absorption, which can avoid crack or damage of other components caused by the long-
time vibration and separate structure between air-return box and base. Improve the
machine reliability and durability.

18. Best Seller–HC2000 Pendulum Grinding Mill
HC2000 grinding mill is a large pendulum
roller mill developed by our engineer on the
basis of HC1700 grinding mill. With 5
patents, HC2000 grinding mill is widely
used to grind almost any non-metallic
minerals with Moh’s hardness below 7 and
moisture below 10%, such as kaolin,
calcite, marble, talc, manganese, ceramic,
etc. The fineness can be adjusted from
0.18mm(80 mesh) to 0.038mm (400
mesh). HC2000 grinding mill not only live
up to the national industrial policy and
meet the needs of mass production, but
also fills the gap of large-size mill in the
mill industry. It plays a leading role in
