Jul 01, 1993 Abstract. We present the results of a study on process energy use of two asphalt-mixing plants. The production process involves the mixing of granite aggregates and bitumen to give asphalt mixtures. The mixtures are widely used as a road-paving material. A large part of the process energy use is for drying and heating the aggregates.
Continuous mobile asphalt plant EXTERNAL MIXER PUG MILL TYPE 4 Pug-Mill type bitumen injection is carried out in the mixer directly on the aggregate - out of the dryer, in a controlled environment - preserving the quality of the binding agent and ensuring homogeneity of the asphalt mass. Maximum mechanical energy applied on the mix.
Step 4 Segregation As Per Size. These materials, in the asphalt plant, are then segregated into different bins based on their size by multiple-layer vibrating screens. Step 5 Storage in Separate Bins. The materials are then stored in separate bins based on their size below the vibrating screen.
Sep 01, 2020 Once these materials reach the processing area, these aggregates enter the aggregate plant that often features a feeder or vibratory crusher. These plants feature a primary crusher that performs the role of reducing the size of the aggregates into smaller chunks around 6-inches in circumference.
characteristics are determined by the relative amounts and types of aggregate and RAP used. A certain percentage of fine aggregate less than 74 micrometers m in physical diameter is required for the production of good quality HMA.
