Used Promax Compact Concrete Mixing Plant for sale (9,130)

Condition: used, Polygonmach stationary hot mix asphalt plant refers to an asphalt plant that is fixed in one location and produces hot mix asphalt continuously. It is not portable and is typically used for large-scale asphalt production projects. Capacity vary from 60-400 tph. The functions of Polygonmach stationary asphalt plant includes: Aggregate Storage and Handling: The plant has storage bins or silos to store various sizes of aggregates. These aggregates are sorted and fed into the plant for processing. Gkodsx D A D Rspfx Ak Ujb Drying and Heating: The aggregates are dried and heated in a drum or a dryer to remove moisture and bring them to the desired temperature for proper asphalt mixing. Asphalt Binder Storage and Heating: The plant has storage tanks for storing the asphalt binder, which is heated to a specified temperature before mixing with the aggregates. Mixing: The heated aggregates and asphalt binder are mixed together in the plant to produce the hot mix asphalt. The mixing can be done in a batch or continuous process, depending on the type of plant. Storage and Loadout: The hot mix asphalt is stored in silos or storage bins until it is ready for loadout onto trucks for transportation to the construction site. Usage areas for Polygonmach stationary asphalt plants include road construction, highway projects, airport runways, parking lots, and other large-scale asphalt paving applications. The operation of Polygonmach stationary asphalt plant typically involves the following steps: Aggregates are stored in the designated bins/silos of the plant. The aggregates are fed into the drying drum, where they are heated and dried. The heated aggregates are then transported to the mixing unit. Options: stationary, continuous Capacity: Max.: 400 t/h(245 lb/s)Min.: 60 t/h(37 lb/s)
