Introduction of  Multistage Chalk Powder Grinder Machine Large Capacity

 
HD-D Series   Multistage Chalk Powder Grinder Machine Large Capacity is a kind of   Raymond Mill  which is a very high cost performance model developed by our company according to customer demand.The operation of this Raymond mill is the same as the ordinary powder mill but can produce Multistage Mine Powder .
This type of Raymond mill is designed with two powder ports. The particle size of the first powder port is adjustable from 80 to 325 mesh.According to the requirements of users, the secondary powder outlet can be equipped with vibrating screen to obtain a variety of products with different materials.
 
Application of  Multistage Chalk Powder Grinder Machine Large Capacity
With scientific & reasonable design and its unique advantages , HDD sieries Raymond mills  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

 
Advantages of  Multistage Mine Powder Mill Raymond Mill 
1. One machine can produce many kinds of particle size finished stone powder.
(1) The main mill can produce two kind powder with basically the same output: coarse powder and fine powder.

(2) Supporting vibrating screening system can screen coarse powder into multi-stage finished stone powder

2. No repeated grinding, low power consumption and high output
3. Compared with domestic traditional pendulum mill (Raymond mill).At the same time of producing fine powder, coarse powder equivalent to fine powder is produced.
4. Installed power unchanged while output doubled; Output increased by 100% (coarse powder, fine powder), energy consumption reduced by 50%.
5.Low investment cost, small equipment occupies area.
6.Saving energy, environment friendly
