HMA Batch Plant – Pavement Interactive

This means that as older batch plants are retired they are more than likely to be replaced by new drum plants, which can provide greater mobility and production capacity. Typical batch quantities range from 1.5 to 5 tons of HMA. Figure 1 shows the basic components of a batch plant and their functions. Figure 1.

HMA Drum Plant – Pavement Interactive

Drum plants, which produce HMA in a continuous manner, generally offer higher production rates than batch plants for comparable cost. Typical production rates for drum plants vary between about 100 tons/hr up to over 900 tons/hr depending upon drum design. Figure 1 shows the basic components of a drum plant and their functions.
