400 Mesh Marble Powder Processing Plant In Pakistan-21 Roller Mill

 

The above video shows CLIRIK's 21 roller mill (HGM80 ultrafine grinding mill) applied to a marble grinding production line in Pakistan.
 

Background of the project

In this case, the customer needs to use ultrafine grinding mill to produce 400-800 mesh calcium carbonate powder, and the output requires 2-4 tons per hour.

The entire marble grinding production line includes crushers, elevators, silos, mill systems, packaging machines and electrical control cabinets.
Among them, the crusher, elevator and silo are purchased locally by customers. This is also the choice of many Pakistani customers. This is because these three products are very common in Pakistan, and the technical threshold is low, so choosing to buy locally is cheaper and can save freight (especially the silo, which is large in size and usually adds more freight).
 

HGM80 21 roller mill is popular in Pakistani market

CLIRIK's HGM80 21 roller mill is very popular in the middle east, especially in Pakistan. 
It sells very well in Pakistan, especially in Lahore, Peshawar, and Mardan. We have many 21 roller mills working there. 
Our well-known partners like Shaheen Grinding Mills, Dawood grinding mills, Abdullah grinding mills, and so on. 

HGM Series Micro Powder Grinding Mills

HGM80 grinding mill is only the smallest model in HGM series micro powder grinding mill, other models include HGM90, HGM100, HGM125, HGM1680 (they also named 21/24/28/32 roller mill), these models can be applied to different materials and larger output. The following are the specific parameters of the HGM series grinding mill for reference.

It can be seen from the above parameter table that the HGM series micro powder grinding mill can process a wide range of fineness of materials, ranging from 150 mesh to 3000 mesh, and can be applied to the vast majority of ultra-fine powder processing.

Especially in the field of calcium carbonate, HGM series grinding mill have absolute advantages, which is mainly reflected in the fact that HGM micro powder grinding mill are different from the traditional Raymond mills by adopting a multi-layer roller mill structure to make the grinding efficiency higher.
The accessories can not only increase the service life of wearing parts, but also reduce the iron content of the split machine, and the calcium carbonate powder produced is of higher quality.
As for PLC intelligent control system and automated packaging system, customers can choose according to their own needs.
 

Can all materials be processed by HGM grinding mill?

Of course not, no matter how good a product is, it has its scope of application and limitations.

The HGM grinding mill is mainly suitable for the grinding of non-metallic ores. The hardness of the grinding material should preferably be below 6 on the Mohs scale, and the humidity should be below 6% (if the humidity is too high, a dryer is recommended).
Common materials are: marble, calcite, chalk, limestone, dolomite, carbon black, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite , diatomite, barite, gypsum, alunite, graphite, fluorite, phosphate rock, potassium ore, pumice and other more than 200 kinds of materials.
