Coal Mill Machine 400 mesh 50TPH HD DBM Series German Type

Application Range of HD DBM Series German Type Coal Mill Machine

HD-DBM Series German type Coal Mill Mahcine is also grinding mill for stones. This Grinding mill is widely used in the fields of metallurgy,chemical industrial, electric power, oil, and non-metallic mineral processing, etc. The products of stone grinder are mainly used for industrial desulfurization, the interior and exterior wall coatings of the buildings, plastic rubber filling, paper-making, feed supplement and the recycling of slag.The calcium carbonate powder 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, liemstone , coal 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 HD  Series Coal Mill Machine：

1.High efficiency. 

• High efficiency of primary grinding, 20-30% higher than the domestic mill of the same type;

• Using large grinding roller;

• Total power is invariant while the grinding force has been improved 30% .compared with the domestic traditional mill with the same specification: the power is unchanged, the grinding force is increased by 30%, the efficiency of primary grinding is improved, and the output is increased by 20-30% compared with the domestic mill of the same type.

2. Flexible coupling Between Housing and main mill;The housing will never crack.

• 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.

• 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 . The possibility of main mill housing been cracked is minimal.

• German Type Grinding Mill; Traditional Grinding Mill in China;

• “H” Means HangDa; Flexible coupling between housing and main mill; Housing is easy to crack;Bolts is easy to break;

• Solid coupling between housing and main mill.

3. Reinforced Return Air Box

High strengthen structure, Secured with double- row bolts.

4.Central shaft will never have wear and tear,easy maintenance 

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)Difficult 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 Series Grinding Mill:

1)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 will never have wear and tear .

2)More easy maintenance 

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.

5.Lower investment cost, energy saving, environment friendly

The main mill is assembled with transducer. The transducer can help the grinding mill to adjust the revolving speed depends on different materials.In this way, the grinding mill runs with low noise, low power consumption stable operation and low loss.

The main mill is assembled with pulse air collector . The Pulse dust collector can collect the after-wind. And this make the flour grinding machine to protect the environment .

Main technical data HD DBM Series German Type Coal Mill Machine :

Note: 

1. The capacity is for limestone powder, and specification is just a reference. The actual production depends on these materials being processed.

2. The ring size is the Outer Diameter× height
