Contending with stockpile segregation, product
2020-3-19 After the aggregate is blended into an asphalt or concrete mix, segregation can also take place during the application of the final mix to the road or other surfaces. Figure 1. Segregation in materials can occur at numerous stages, starting with the stockpile.
Reducing drying energy and costs by process
As an example, the knowledge on drainage is applied to the stockpile situation at an asphalt production plant. Figure 9 denotes the moisture behaviour at the stockpiles of river sand and granulated recycled asphalt. River sand enters the stockpile with a yearly average of 5.8% and increases to 6.5% due to precipitation, while the drainage ...

2006-10-23 6 Aggregate Storage and Handling The storage and handling of both new aggregate and RAP material for use in any type of asphalt plant are ad dressed in this section. Proper stockpiling techniques, both for placement of the aggregate in the stockpile and for removal of the aggregate from the stockpile, are first discussed.
Maintaining proper aggregate stockpiles Asphalt
Minimizing the drop height from discharge can alleviate this problem. “You know segregation is going to occur.” Goad said. To prevent it, his plant loads out of the stockpile. Many Bluegrass plants have paddlewheels at the end of conveyors to blend material as it is stockpiled, he said.
Calculating Stockpile CapacityConical StockpilesElongated StockpilesCalculate Stockpile Live StorageThe conical stockpile is the simplest and easiest to analyze. The total stockpile capacity is given by:3.14 (Tan A)R³ D/3000 = capacity in metric tons(1)where: R = stockpile radius in meters A = angle of repose for material to be stockpiled D = density of material in kg/m³Note that the capacity of the conical stockpile varies with the cube of the radius of the pile. This means that the capacity of the conical pile grows very rapidly as 在911metallurgist上查看更多信息
