Recycling of End of Life Concrete Fines into Hardened

The expected amount of CF for milling in an industrial scale is around 30 tons per hour (if ADR is run at 100 tons per hour). Changing the residence time from 300 to 90 seconds, while the throughput is constant at 30 tons per hour, demands a ball mill with a shorter length. Thus, the total cost of milling drops significantly (see Table 1).Get price

Effect of feed size on residence time and energy

2021-2-1This indicates that shortening the residence time of materials in the mill as much as possible was beneficial for class 1 to be broken into class 2. However, shortening the residence time of materials would increase the load of the classifier in a milling circuit. Therefore, the grinding time should not exceed the switch point at least.Get price

Clinkerization

Length and diameter of kiln is decided for the required capacity throughput. Main factors dictating size of kiln are the retention time (25-30 minutes) of material in kiln, degree of filling (10-17%) and thermal loading of burning zone (2.8-4.8 x 10 6 kcal/h/m 2). Pre-calciner kilns are shortest in length, as 90-95 % calcination is completed Get price

Average residence time?

The average residence time is a measure of the time it takes for the total stock or supply of the material to be cycled through a system. To compute the average residence time (T; assuming constant size of the system and constant rate of transfer), we take the total size of the stock (S) and divide it by the average rate of transfer (F) through the system: T=S/F.
