German Type Fine Grinding Mill Quartz Powder Making Machine HDW

HDW Series German type improved grinding mill is widely used in the fields of metallurgy,chemical industrial, electric power, oil, and non-metallic mineral processing, etc. The products 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.

With scientific & reasonable design and its unique advantages ,HD DBMW  German Type Fine Grinding Mill are applied widely in power, metallurgical, cement, chemical and non-metallic industry, for grinding of various materials, such as cement raw material, clinker, limestone, slag, manganese, gypsum, coal, barite, calcite 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.Time-saving,Convenience Maintenance, Low labor Strength :

Three Steps only for maitenance of HDW Series German Type Improved Grinding Mill 

2.The housing will never crack

HDW Series German Type Improved Grinding 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-DBMW 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 .

3.Center shaft withstands even the greatest wear and tear,  Seal parts of the center shaft is easy maintenance 

HDW German type fine powder 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 can withstands even the greatest wear and tear

2)More easy maintenance 

3)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.

4.Suitable for grinding hard and powdery materials

HDW Series German Type Fine Powder Grinding Mill has no return air box and no air duct guard plate structure. And the grinding chamber is full of negative pressure. which makes the powdery material in the sealed grinding chamber to be ground perfectly.

The powdery material is ground in the closed grinding chamber.  Then the finished powdery material is pumped to the classifier to be classified by the negative pressure . since there is no positive pressure in the lower part of grinding chamber, the powdery material will no be raised in the grinding chamber due to positive pressure.This ensure the effective grinding of powdery material in the grinding chamber.

Traditional grinding mill ；

There are positive pressure air ducts around the base of traditional domestic mill .This makes the powder easy to raise , resulting in less abrasive fabric surface .Since hard materials have low grind-ability , when the grinding mill works, the equipment will subjected to large impact force, fast loss,large vibration, loud noise,fast loos and low output. Thus,HD-DBMW Series German Type Fine Powder Grinding Mill is designed specifically for the whole powder material and hard material ideal model. 

5.   Assembled with new technology ultra-fine classifier: 

HDW Series German Type Fine Powder Grinding Mill：

Turbine blades of ultra-fin classifier are vertically embedded in upper and lower panels. The blade will not deform will not deform without welding. With equal blade spacing, high classification accuracy and concentrated particle size distribution, it can separate 325-1250 mesh powdery materials. 

Traditional turbine classifier:

The turbine of traditional analyzers is inclined and fixed on the upper and lower panels by welding. Due to the large amount of welding ,the turbine produces welding stress and deformation,  the blade spacing is not uniform, and the gas dear formed at the top in the labyrinth groove is easy to cause rough running. In order to avoid coarse running, it is necessary  to increase the speed and thus affect the output. The particle size distribution of finished products in scattered, so only 80-400 mesh powdery materials can be sorted.

Tehanical Data

Note:

1. The capacity data is changed depends on the fineness of raw material,this data is for limestone.

2. The ring size is the Outer Diameter× height
