Ball Mill. We bring forth a highly advanced Ball Mill, specifically engineered for both wet as well as dry cement grinding applications. Classified depending on the circuit design, bearing, grinding type and drive, the selection is made on the basis of the product fineness, quality, and nature of raw material, site conditions and specific requirements.
This roller press can improve the grinding capacity by 50- compared to ball mill systems and reduce the power consumption of the grinding system by 30-40%, and 20-30% that of finished cement. The squeezed materials is easy to grind and 0.08mm fine material accounts for 30-30% and material smaller than 20 mm accounts for 65-85%.
The CKP mill was used for the pre-crushing of cement clinker in a Chinese cement plant. The mill has similar grinding rollers and grinding table to the typical roller-race mill, but has no air-classifier inside the mill body. However, part of the ground product was returned to the mill to enable smooth operation.

Cement raw material has been almost exclusively ground in roller mills (vertical air-swept grinding mills) since the sec-ond half of the 20th century. Loesche was and is the pio-neer of this technology. Hundreds of Loesche mills have been used in the cement industry across the world to the present day. They operate with two, three, four and six ...
The cement ball mill is mainly used for grinding the finished products and raw materials of cement plants, and is also suitable for grinding various ore and other grindable materials in industrial and mining enterprises such as metallurgy, chemical industry, and electric power. Cement grinding is the last process of cement production, it is to ...

This example shows that grinding circuit simulation can be used to analyze the production circuit, to optimize the operating parameters and to reduce energy consumption. 4 Modeling a vertical roller mill A mathematical model for the grinding process in vertical roller mills has been made. The cement plant's vertical roller mills (CKP ...
Cement & Blast Furnace Slag. The coordinates of the grinding table diameter and number of rollers can be read off from the table. The x-coordinate indicates which product throughputs can be generated using the respective mills. The width of the fields is a …
A 1.5 mio t/a cement plant is having a closed circuit ball mill for cement grinding: The mill has been operating with satisfactory performance in-terms of system availability and output, however power consumption was on higher side. 3.1 System Description Mill Rated capacity 150 t/h OPC at 2800 blaine I chamber liners
We use a closed-circuit grinding process to obtain a very finely ground cement. A size particle range of 3 to 30 microns (one micron is a thouh of a millimeter!) results in the most efficient hydration of cement and better strength properties, including more late strength. The Wonder Cement factory process is now complete.

The revised model can express the grinding process of CKP mill on cement clinker. The parameter a (min − 1) reflects the material property grinding by CKP mill. There is a linear relationship between the value of the grinding rate and the logarithm value taking 10 as base of the particle size. Download : Download high-res image (181KB)
Summary: The main trends concerning grinding processes in the cement industry are still higher efficiency, reduction of the power consumption and system simplicity. In the case of new orders, vertical mills have increased their share to over 60 % and ball mills have fallen to less than 30 %. It is somewhat surprising that the number of different grinding processes and mill types used …
