HD-DBMC Raymond Mill

HD-DBMC German  Improved Raymond Mill can be fit for kinds of ore material with Morse hardness below 7 such as: Calcite, Limestone,Barite,Gypsum, Potash feldspar, Kaolin, Bentonite, Bauxite,Talc, Dolomite,Tabular spar,Phosphorite,Manganese ore, Marble, Iron ore, Copper ore,Aluminum ore etc. The grinding field is wide and grinding type is abundant.

1. Humidity of grinding materials: from materials of less than 6 %(such as cement clinker), wide range of materials.
2. Grindability of materials: from high grindability(such as quartz sand, steel slag, mining slag, pyrophyllite, iron ore etc.) to low grindability (such as gypsum, calcite, etc).
3. Fineness of grinding product: from 2-5mm(such as raw shale for making brich in new wall material industry, sand for construction industry, etc) Product fineness is easy to adjust and simple operation

Performance Advantages：

1.Revolutionary and innovative technology for the unique structure:

This type of grinding mill designed without relieving tool post and center shaft frame to reduce the rate of malfunction.

       2.Time-saving,Convenience Maintenance, Low labor Strength :

The maintenance time is 1/4 of that of traditional grinding in china. To service the grinding ring of the traditional grinding mill, workers need at lest 2 days while the improved grinding mill need half a day only.

          Only 3 Steps for Improved Raymond Mill

•  Step 1. Dissemble the housing 

• Step 2. Take out the ring with the bracket 

• Step3. Dissemble the new grinding ring. 

  

3.The housing will not easy to crack,Center shaft withstands even the greatest wear and tear

Maintenance steps for the traditional grinding mill :

1. Find one 10 tons’ crane;

2. Disassemble  the pipe system;

3. Disassemble  the classifier;

4. Disassemble the feeder;

5. Disassemble  the classifier bracket 

6. Disassemble  the housing

7. Disassemble  the roller assembly

8. Disassemble the Plum Blossom Rack

9. Change the ring 

10. Install all the parts again.

HD-DBMC German  Improved Raymond Mill :

1）Housing designed with folio door，easy disassembly.

2）Lock catch design between classifier and main mill,easy disassembly.

3） Flexible coupling between housing and main mill，this can help the housing being away from the grinding chamber ;

4）Possibility of main mill housing been cracked is minimal:HD-DBM Series German Type Grinding Mill assembled with flexible coupling between housing and main mill.When the main mill works, the housing will have no force and vibration . This can help the housing will be strong enough .

Traditional grinding mill:

1)Lubricating oil leakage . After working for a certain period of time ,an oil groove will come into being in the skeleton oil seal parts of the central axis because of the abrasion. This can cause lubricating oil leakage and then the central axis will stop working. 

2)Hard maintenance. To service the central axis, workers must dismantle the main mill first which will take us a lot of time. And then,replace the seals after the central axis being taken out and being placed upside down. To finish these actions, it is more work than to replace the grinding ring .

         HD-DBMC German  Improved Raymond Mill :

         New technology structure to protect the center shaft. The framework oil seal is installed with new technology structure to protect the center axis. Thus,the center axis of main mill can withstands even the greatest wear and tear

        1)More easy maintenance 

        2)To service the oil seal equipment, workers don’t need to disassemble the main mill any more. Workers can replace the oil equipment from the repair tank of the reducer. This can save the equipment maintenance time and labor intensity greatly.

        Traditional grinding mill:

        The traditional connection between housing and main mill is solid coupling  . When the main mill works, the housing will vibrate seriously so that the housing will been cracked and the bolts will been broken easily.

       4.High efficiency, The capacity of HD-DBMC Series German Type Grinding Mill   is 10-20% higher than that of the same type of grinders in China. 

       HD-DBMC Series German Type Improved Grinding Mill is assembled with less but bigger grinding rollers than ever.  The grinding force is 20% higher than the traditional types in china. Whats more, the space of the grinding chamber been enlarged to reduce the resistance of grinding chamber transportation. This helps the capacity of the grinding mill being 10-20% higher than that of the same type of the traditional mills in china.
