Vertical roller mill: can be used in 300 kinds of different soft and hard mineral powder grinding, such as: cement, slag and other hard material, it's easy to process by vertical roller mill, and compare with Raymond mill the vertical roller mill has a high capacity and powder fineness grinding ability.

Roller mills accomplish size reduction through a combination of forces and design features. If the rolls rotate at the same speed, compression is the primary force used. If the rolls rotate at different speeds, shearing Hammermills and Roller Mills Kim Koch Northern Crops Institute North Dakota State University Fargo, ND

Vertical roller mills Vs ball mills has long been a raging debate in the cement industry.

Horizontal roller mills use 65-70% of the energy used in ball mills. Roller press (high-pressure grinding rolls): In this technology materials are crushed between two counter-rotating rollers. These rollers are up to 2 m in diameter and 1.4 m long. Roller presses use 50-65% of the energy used in ball mills.

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 decided advantage over a ball mill system. However, despite these benefits, applications of the vertical roller mill for cement grinding are less prevalent.

The effect of different grinding mechanism on breakage parameters was investigated in this paper. Ball mil and vertical roller mill were used as …

Comparing to the widely applied ball milling, the second law efficiency is 16.4% higher for the VRM than the ball mill. Results also showed when the classifier rotor speed increases from 53 to 65 rpm, the particle size of the product decreases from P 90µm = 18.2% to P 90µm = 10.8%, but the power consumption of the VRM unit increases from 19.7 ...

Cement grinding Vertical roller mills versus ball mills. The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition.

Vertical roller mills can have lower power than ball mills in most applications for dry grinding. One comment that I did not see here is the potential for differential grinding, especially in vertical mills, but also in ball mills. That is when inter-grinding different materials, the softer materials tend to be ground finer.

Although the ball mill is significantly less efficient than the vertical roller mill in producing slag powder, the materials can be retained for a longer time in a ball mill, and the degree of structural disorder increases under mechanical force, producing more activation sites on the particle surface.

the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill power.
