Roller Mill

We can provide the roller mill for making ultra-fine powder which is suitable to grind the material with mosh hardness below 7 and moisture below 6%, with processing capacity 500-25000 kgs/h. The material passes through the gap between the rolling grinding roller and the grinding ring for pulverization, and then separated by the turbine classifiers into ultra-fine products.

Feeding Size: Max. 20 mm Output Size: 5-45μm


Prominer can provide the service work as below

Physical property analysis
Lab and pilot test
Complete grinding solution
On-site erection & commissioning and training


Our equipment with the main advantages as below

Roller mill has the advantages of high efficiency of high-speed impact mill, and the product of the roller mill has a fineness close to airflow mill.
Better wear-resisting performance
Super-hard alloy type hammer and ring with longer service life.
High efficiency dust control
Collecting efficiency up to 99.99%, Negative pressure operation without fly ash.
Compact structure absorbing shock
The host base adopts an integral casting structure, which not only ensures structural strength but also has good shock absorption performance.
Turbine grading system
Easily adjust the fineness of finished products between 5-45μm.
Easy to operate
Fully automatic PLC control.


It is mainly for handling the calcined petroleum coke (CPC coke), calcined needle coke, coating pitch, natural graphite for lithium battery anode material production.

It can handle limestone, feldspar, calcite, dolomite, marble and quartz also.

Project Cases

Roller mill for grinding calcined petroleum coke

Calcined petroleum coke has a sponge-like structure which plays an important role in the making of anodes.

Roller mill for grinding petroleum coke

Calcined petroleum coke is created by placing high quality green petroleum coke into rotary kilns, where it is heated to temperatures between 1200 to 1350 ˚C.

Roller mill for grinding calcined needle coke

Needle coke, commonly used in the production of high-power graphite electrodes for steel production in electric furnaces.

Roller mill for anode material plant

Ultrafine grinding equipment with built-in grinder and classifier, the material is fed into the grinding ring to be collided repeatedly and milled by grinding rollers.

Roller mill for UHP graphite electrode project

Calcined Needle Coke Is a High Quality Material for Manufacturing HP and UHP Electrode.

Roller mill for limestone grinding

Roller mill not only fit for artificial graphite processing, but also for handling limestone, feldspar, calcite, dolomite, marble and quartz.

Roller mill for dolomite grinding

Roller mill could reach the ultra-fine grinding for dolomite with high efficiency and low wear cost.

Roller mill for special graphite project

CPC's strength, density and size also make it ideal for the production of Aluminum and Graphite electrode.
