Mill Feeders: Feeders will be directly installed under hoppers with rod gate in between. The feeders are generally 2 to 3 m long and discharge on to a common conveyor which will take feed to mill. Feeders for mills meter feed rates and also tantalize tons fed. For cement mill feeding, table feeders, belt feeders, and weigh feeders have been used.

The 15,000 pounds given above obviously does not include the weight of the footing itself so we need to calculate the weight of the concrete and add it to the total load of 15,000 lbs. Normal weight concrete weighs about 150 pcf (pounds per cubic foot). Using 10 inch thick for the 2'-6"x2'-6" footing, the footing volume

V = 17,641 in3 We have to subtract out the volume of the square hole in the middle (13 in * 13 in * 8 in = 1,352 in3) V = 17,641 in3- 1,352 in3 V = 16,289 in3 Now we can multiply this by the density of quartz to get the weight of the millstone. Weight = 16,289 in3* 0.1 lb/in3= 1,629 lb Over 3/4 ton!

Like the raw mill and finish mill applications, the infeed device's role here is as an airlock. A weigh belt system controls the feed rate. In most cases, coal mill feeders are smaller than raw mill or finish mill feeders with capacities of 10-100 tons per hour.

Aluminum sheet How to calculate the weight The weight of sheet is easily calculated. Simply multiply the appropriate alloy density (see chart below) by the length, width, and thickness of the required part (see worked example below and note that we have used the density of alloy 2014 as the basis for our calculations). Metric […]

Concrete weighs 150 pounds per cubic foot (based on numbers from the table above). Based on this information, you would perform the following calculation: Complex concrete shape = 78 cubic feet x 150 pounds per cubic foot. Complex concrete shape = 11,700 lbs. / 5.85 tons. Using Load Cells or Dynamometers to Determine Load Weight

With 1055 horsepower, the RX-900 is the most productive cold planer available. Power and heavy-duty construction make the RX-900 the tool to own for high-productivity, half-lane, or full-lane milling. The machine cuts up to 14" (35.6 cm) deep and can be outfitted to work with different cutting widths. Standard widths are 7'2" (218cm), 8 ...

A typical concrete mix weighs 150 lbs per cubic foot, 4,050 lbs per cubic yard, or 2,400 kg per cubic meter. The weight of concrete is determined by its density, which can vary based on the amount of aggregate, water, and air in the mix.

Weigh the container with the concrete (2) - record value to nearest tenth of a pound. Subtract the empty container weight from the full container weight (2) - (1) = weight of concrete (3) Divide the weight of concrete by the known volume (3) / (4) = density, or fresh unit weight. There are a few unique procedures listed in the ASTM C138 to ...

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner …
