(granulated blast furnace slag, fly ash, pozzolanes, limestone etc.). The grinding of the finished cement consumes approximately one third of the total electrical energy of a cement plant. Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press.
The occupied area of vertical roller mill is only 50% of ball mill, and reduce the investment directly. ... EPC turnkey project Industrial waste slag grinding station Oct 9, 2018
Two way grinding system for cement and slag grinding and high efficiency classifier ensures saving in power consumption (approx. 30% 40%) as compare to ball mills. Easy Maintenance and Operation UBE AMCL Mills offers with swing out features for easy removal of Roller liners during maintenance.
The blast furnace slag ball mill is used for professional production of ground blast furnace slag. Blast furnace slag is a material composed of calcium oxide, sulfur dioxide and chlorine xide. It is a byproduct of blast furnace iron making, which will pollute the air and cause human respiratory diseases.
energy requirements for cement grinding construction costs and improving the • Spacesaving design and 4050% for slag as compared with working environment. reduces civil traditional ball mill operations, the OK Because of its highly effective drying construction costs.

These features distinguish stirred mills as fundamentally different from both ball mills and Tower Mills, as demonstrated by Tables 1 and 2. Table 1 : Typical Power Intensities of different Grinding Devices Table 1: Power Intensity of Different Grinding Devices Ball Mill is a D x L Tower Mill is a D x L 520KW
The grinding process was carried out in a cylindrical ball mill with a diameter and length of cm and cm, respectively, as well as a steel ball with a diameter of cm and a weight of 100 grams/ball. The optimum data for the grinding process was obtained with the smallest response value of P80.
A series of tests were performed in a laboratory ball mill using (i) three loads of single size media,, 40,, and mm and (ii) a mixed load of balls with varying sizes. In order to simulate the industrial ball milling operation, the feed to the mill consisted of slag with natural size distribution less than 850 μm.

Grinding balls are irreplaceable elements in ball mills widely used in many industries. The operating properties of grinding balls have been studied in many works [1,2,3, 4]. Their wearing is inevitable but should be uniform. However, the sizes of the grinding balls decrease unevenly in operation due to selective wear.
The ultrafine slag slurry (UFSS) was obtained by the process of grinding the original slag in a wet ball mill, which was mixed in concrete directly. The durations of grinding were 20 min, 40 min, and 60 min which were used to replace Portland cement with different percentages, namely, 20, 35, and 50, and were designed to compare cement with ...
