  • Coarse grinding with ball mill Grinding & Classification

    Hello Dear Experts, I bought a new ball mill which's 900x3000 size. I am planning to grind river sand that has %60 silica in it's chemical proportion. But for me it's unnecessary to grind very fine like 600 micron or near, I just want to receive 0-3 mm final product. My feed size is : 3 mm . to 25

  • Ball mills for various applications Gebr. Pfeiffer

    When performing circuit grinding, the product fineness can be set at the separator. In case of coarse grinding where a downstream screening machine is provided, the product fineness can be preselected by providing a specific mesh width on the screening machine.

  • Modeling breakage rates of coarse particles in ball mills

    Jun 01, 2009· The first-order rates are commonly observed in batch grinding (Austin et al., 1984) and are the basis of modeling breakage in tumbling mills.In the case of particles contained in coarser size ranges, deviations from linearity are identified in Fig. 1, as have been observed by other investigators (Austin et al., 1982).This behavior, in which grinding rates appear to slow down with time, has

    The effect in this job is better than coarse grinding. Grid ball mill consists of the shell, feeding part, discharging part, main bearing, lubricating system, driving system and other parts. There is wearing a liner inside the shell, and both ends of the shell are provided with a flange. The end cover of the mill is connected with the flange plate.

  • Horizontal Coarse Grinding Mill Rod Mill Product

    Unlike the Ball Mill, however, the Rod Mill uses rods instead of balls as the grinding medium. As a result, its uses are different from those with the Ball Mill. In other words, the Rod Mill gives impact on and grinds coarse particles present between each rod,

How Coarse can Ball Mill Feed be GrindingFeeding >15mm to a ball mill this size is not typical much larger ball mills (>21' or 70m diameter) typically get 12-16mm feed (from what I have seen in my experience) With regards to 35"- 4" media, typically for Ball mills of this size (16'), max size of ball used

  • Comparison of energy efficiency between ball mills and

    Jun 01, 2009· The work using a vertical shaft stirred mill compared with Bond ball mill, both operated in closed circuit with a classifier, demonstrated a clear trend that on average 30% energy saving can be expected by using the stirred mill to replace ball mill for coarse grinding from a top particle size 3.35 mm to P 80 less than 100 μm.

  • Rod Mills for coarse grinding FLSmidth

    Grind coarse feed material with a reliable Rod Mill that won't over-grind. If you are in need of an application for coarse materials like limestone, potash, coal, phosphate and bauxite, you may be looking for a solutions like Rod Mills. Rod Mills are particularly useful, if you run a low tonnage operation and are looking for coarse product.

  • Simulation of the grinding of coarse/fine (heterogeneous

    May 08, 2011· For the grinding kinetics of dolomite (Fuerstenau and Abouzeid, 1991), it was shown that the breakage rate of the coarse fraction increases as the fine fraction in the mixture increases, Fig. 1.As it is obvious, this trend is similar to the breakage rate trend in both quartz and limestone (Fuerstenau et al., 2010).The only difference is in the value of the breakage rate where it is in the

  • What's the Difference Between SAG Mill and Ball Mill

    The feed of the ball mill contains grinding balls. In order to effectively reduce the direct impact of materials on the ball mill feed bushing and improve the service life of the ball mill feed bushing, the feeding point of the groove in the feeding part of the ball mill must be as close to the side of the mill barrel as possible.
