  • Comparing ball and vertical mills performance: An

    Figure 6 Particle size distributions from ball mill and vertical mill circuits. Since the automatic sampling system from concentrator II takes samples only from the combined streams on the regrinding circuit, a series of manual sampling campaigns were conducted along the year of 2012 to make this study possible. Figure 7 shows the results. Figure 7 Sampling results (k

  • What is the difference between vertical mill and ball mill?

    5. Lower initial cost. The initial construction cost, running cost and maintenance cost of the vertical mill are only 70%~80% of the ball mill equipment. 6. The particle size of the grinding material is large, which can reach 3%-5% of the diameter of the grinding roller. The large-scale grinding allows the material to have a large particle size

  • Study on the particle morphology, powder characteristics

    The degree of sphericity of the blast furnace slag powder particles decreases with the particle size and is lower when produced by vertical roller milling than by ball milling; the differences in particle morphology mainly exist at the 0–3 μm particle grade. For the same specific surface area, ball-milled slag powder has a higher angle of repose, natural bulk density and tapped

    Stable chemical composition and even particle size products. 5. Simple process flow and small in size. There is a segregator in the vertical mill, which makes powder separator and elevator unnecessary. Grinded dusty air can directly enter into the environmental protection equipment. So its process flow is quite simple and compact. Its structure size is only 70% of that of the ball mill

  • Cement grinding Vertical roller mills versus ball mills

    The following presents a comparison of the two mill systems with reference to these issues. Grinding process The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture

  • The Vertical Mill Slag Micro-Powders' Particle Size

    Vertical mill grinding system is one of the important cement grinding equipments developed in recent years. In this paper, through the industry vertical mill grinding GGBS carried out a detailed analysis of particle size, on this basis, using the attached to the sample preparation method, obtained the typical SEM images of GGBS through industrial vertical mill, and using particle image

  • Differences Between Vertical Grinding Mill and Ball Mill

    But for the ball mill, when grinding high moisture materials, it is very necessary to install extra drying equipment in front of the ball mill due to its limited air flow through the ball mill. 4. The space occupied by the vertical mill is only 50% ~ 70% of the ball mill, and the physical space occupied is smaller. 5. Lower initial installation

  • Effect of mill type on the size reduction and phase

    29/09/2015· Air jet milling is found to be the most effective in reducing particle size from a d 90 of 37 µm to 2.9 µm compared to planetary ball milling (30.2 µm) and single ball milling (10.5 µm). XRD and TEM studies confirm that the planetary ball mill causes phase transformation to the less desired α-Alumina resulting in a notable decrease in surface area from 136.6 m 2 /g to 82.5 m 2 /g as
