The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000. where: W = weight of charge. C = distance of centre of gravity or charge from centre of mill in feet. a = dynamic angle of repose of the charge. N = mill speed in RPM. HP = A x B x C x L. Where.
grinding process ( cement grinding in a ball mill to a grinding fineness of 3000 cm2/g Blaine), the grindability of a material is characterized in k'Yh/t, the grinding resistance in kgjk Who It is almost superfluous to mention that the grinding equipment influenc'es these values too. So, for example, for cement raw meal grinding.
Objectives. At the end of this lesson students should be able to: Explain the grinding process. Distinguish between crushing and grinding. Compare and contrast different type of equipment and their components used for grinding. Identify key variables for process control. Design features of grinding equipment (SAG, BALL and ROD MILLS)

HARDGROVE GRINDABILITY INDEX. The Hardgrove Grindability Index was developed as an empirical test to indicate how difcult it would be to grind a specic coal to the particle size necessary for effective combustion in a pulverized coal red boiler. Its use has been extended to cover the preparation of pulverized coal for the cement, steel and ...
The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this ...

1) alite size, as before. 2) C2S content, as before. 3) grinding aid. Cost €/t, usage 150400 g/t. As the cement particle gets smaller the pores disappear and no longer become a factor. Increasing the amount of grinding aid will make the cement easier to grind. Hard burning = hard grinding.
The throughput of a cement grinding ball mill depends on several factors, including the size and hardness of the feed material, the size and speed of the mill, the filling level of the grinding ...
Hardgrove Grindability Index (short HGI) is a measure for the grindability of coal. Grindability is an index, therefore it has no unit. The smaller the HGI, the harder is coal texture and less grindable is the coal. Grindability is an important factor for the design a coal mill. As grindability depends on many unknown factors, HGI is determined ...
The sample was received crushed appropriately for the ball mill test. Ball Mill Grindability Test was conducted by standard practice using 100mesh (150 pm) closing screens. The ball mill work index is shown below. BM Wi (kWhr/st) = ; BM Wi (kWhr/mt) = ; Bond Ball Mill
