Comparison. When grinding raw meal, the unit power consumption of the vertical roller mill and the roller press is about the same, which is 7-8kWh/t. But the vertical mill is usually slightly higher. The system of the vertical grinding mill is simple and stable. It has ideal adaptability to material moisture and can achieve the goal of energy ...

The raw material grinding in the cement industry mainly uses vertical mills, which are more economical than ball mills. The raw material mill does not have high requirements for the fineness of the discharge, and the ball load is relatively small compared to the cement mill, and does not require finer steel ball grading.

Difference between vertical grinding mill and bowl mill. difference between raw mill and ball mill . cement grinding vertical roller mills versus ball mills. cement industry the ball mill was really an epochmaking breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal and still today

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

comparison between ball and vertical grinding mills. A cement mill (or finish mill in North American usage) is the equipment used to grind the hard nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

OPTIMITIVE's last deployment in the US successfully optimised a whole cement plant, including a vertical raw mill (VRM), a kiln, and three ball mills. This project was delivered in 2020, resulting in an improvement in plant performance. Throughput was incremented 10% in the ball mills, 6.8% in the kiln and 6% in the vertical raw mill during ...

The two-compartment ball mill operating in a closed circuit with a high efficiency separator is thus still the most preferred arrangement for new cement grinding installations although the vertical roller mill now has emerged as a viable alternative to the ball mill system and has increased its share of the market for cement mills over

VRM has less flexibility in controlling particle size distribution. Overall ball miil is good option for Cement mill but only has limitations for higher capacity, as two ball mill to be installed for One VRM, but in case of breakdown one ball mill can be in operation. Trust this clear your clarifications on equipment selection for cment production.

Ball mills are factory made and transported to the plant site of the buyer while VRM is built on the site of the cement plant. This helps to reduce cost and complicated logistics issues. The equipment cost is, however, higher for a VRM than a ball mill.

In cement production, tube mills having multi-chambers are traditionally used either in open or closed circuit operations. After the introduction of high compression grinding mills (High pressure grinding rolls (HPGR), vertical roller mill (VRM) and Horomill), various circuit configurations have been developed for energy efficient grinding.

The difference between ball mill and vertical mill in cement grinding Over the last three decades the vertical roller mill has become the preferred ball mill for grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a ...

Cement grinding– a comparison between vertical roller mill and ball mill Zementmahlung – ein Vergleich zwischen Vertikal-Rollenmühle und Kugelmühle 1Introduction About 110 years ago the Danish engineer M. Davidsen pa tented a pioneering invention in France which involved a tube mill with a charge of steel balls or flint pebbles for fine

difference between vertical and horizontal cement mill operation. ... The major differences between horizontal and vertical boring mills lie in the way the machine is installed, the configuration used by the tools, and the way the work material is positioned on the machine. Let us discuss the two different types of boring mills in order to ...

The space occupied by the vertical mill is only 50%~70% of the ball mill, and the occupied physical space is relatively smaller. 5. Lower initial cost. The initial construction cost, running cost and maintenance cost of the vertical mill …

In the vertical grinding operation process, to form a stable material layer, it is required that the grinding material has a suitable gradation, and more than 95% of the particle size is less than 3% of the roller diameter. Excessive feed size will result in poor grindability. Since the gap between the bulk materials is not filled with enough ...

Comparison Of Vrm And Ball Mill In Cement Industry. versatility, etc. A comparison of vertical roller mill systems and ball mills systems for cement grinding has been prepa-red with reference to all these issues.3 In den letzten drei Jahren hat sich die Vertikal-Rollenm hle zur bevorzugten M hle f r das Mahlen von Rohmaterial entwickelt.

(When the ball mill grinds the wet material, due to its limited air flow through the ball mill, additional drying equipment is usually required in front of the ball mill.) 4. The space occupied by the vertical mill is only 50%~70% of the ball mill, and the occupied physical space is relatively smaller. 5. Lower initial cost.
