Slurry is a mixture of a solid and a liquid. The density of a slurry can be calculated as. ρ m = 100 / [c w / ρ s + [100 c w] / ρ l] (1). where . ρ m = density of slurry (lb/ft 3, kg/m 3). c w = concentration of solids by weight in the slurry (%). ρ s = density of the solids (lb/ft 3, kg/m 3). ρ l = density of liquid without solids (lb/ft 3, kg/m 3)
WhatsApp: +86 18838072829Suppose we need to top the driveway with a 2,300 kg/m³ asphalt, we can calculate the total weight of the asphalt needed as follows: Weight = length * width * thickness × asphalt density. Weight = 7 meters * 6 meters × 5/100 meters * 2,300 kg/m³. Weight = 4,830 kg or tonnes. After obtaining the required weight, we can now finally ...

WhatsApp: +86 18838072829The ball mill is a traditional coal pulverizer machine, which has been widely used since it was invented. In the cement plant, the new dry process cement manufacturing requires the moisture content of coal powder to be % ~ %, while that of raw coal is % ~ %. Therefore, the ball mill should have a drying function besides grinding.

WhatsApp: +86 18838072829As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that ...

WhatsApp: +86 18838072829Just as a reminder, it goes as follows: weight = volume × density. For clarity's sake, let's go through a quick example. Let's say we have 15 cubic meters of Portland concrete. The density of this type of concrete in kilograms per cubic meter is 2,300, so the calculation goes as follows: weight of concrete = 15 m³ × 2,300 kg/m³ = 34,500 kg.
