Design Of An Asphalt Drum Mix Plant
Asphalt Drum Mix Plant is used to make a homogenous Hot Mix Asphalt (HMA) paving mixture. All the aggregates asphalt and additives are blended in the Asphalt Drum Mix Plant at an elevated temperature. Cold aggregate storage and feeding, dust control and collection, mix storage, recycled materials storage and feeding are the main operations that take place inside the Asphalt Drum Mix Plant. Here is a comprehensive guide describing the design and working of an Asphalt Drum Mix Plant.
* Aggregate Cold Feed Bins All the aggregate material is fed into the cold feed bins. These bins have gates that control the amount of aggregate reaching the conveyor. Gate opening as well as belt speed controls the material flow. Also, the moisture content of the aggregate is measured and monitored in the cold feed bins. The moisture content determines the asphalt supply rate and its drying time.
* Conveyor & Aggregate Weighting System In modern Drum Mix Plants, the Conveyors are controlled by computers. The material on the conveyor belt is weighed by a weigh bridge. Both the belt speed and the belt weight get recorded in the computer. This way the amount of the material that the conveyor transports per unit of time is accurately determined. * Drum Mixer Aggregates in the primary zone are heated and dried by burners. At the secondary zone, a binder is added to the mix. Parallel Flow Drum Mixer, Counter Flow Drum Mixer, Double Barrel Drum Mixer and Double Drum Plant are the different types of drum mixers.
* Dust Collection System: Dust Collection System comprises of collectors of two types: * Primary Collector- All the large dust particles enclosed in the exhaust gas stream are collected and removed by Primary Collector. Knockout Box and Cyclone Dust Collector are the common types of Primary Collectors. * Secondary Collector- It is used for filtration of the finest dust particles. Baghouses and wet scrubber are the two types of Secondary Collectors. The collection efficiency of both primary and secondary collectors range from 1 micron to 75 microns.ƒ ƒ * Hot Mix Conveyor The hot mix asphalt is transported from the drum to the Storage Silo using the Hot Mix Conveyor. The primary objective of Hot Mix Conveyor is to prevent heat loss and mix segregation. Because of the high temperature of the mix and steep inclined shape, Drag Slats are used. * Storage Silo It is an insulated and heated structure that is used for temporarily storing the hot mix asphalt. Storage Silo helps in preventing plant shutdowns that may be cause due to paving or hauling interruptions. A conveyor delivers the hot mix to the batcher that is at the top of the Storage Silo. The use of batcher is important for the prevention of top-of-silo segregation. Quality Engineers is the right destination to buy best advanced Asphalt Drum Mix Plant.
