1. According to the mixing type, there are two types of asphalts plant:
(1). Asphalts Batch Mix Plants
Asphalt Batch Mix Plants is an asphalts concrete plants with batch mix, which is also known as the discontinuous or intermittent type asphalts concrete plants.
Mix type: Batch mix with mixer
Batch mix means there is a time interval between two mix batches. Usually, batch cycle is 40 to 45s

(2). Asphalts Drum Mix Plants
Asphalt Drum Mixing Plants is an asphalts concrete plants with drum mix, which is also called continuous mixer plants.
Mix type: Drum mix without mixer
2. According to the transport type, there are also two types of asphalts plants:
(3). Mobile Asphalts Mix Plants
Mobile Asphalt Plant is an asphalts plants with transport frame chassis which can move convenient, which is also named portable type asphalts concrete plants, features with modular structure design and transport frame chassis, lower cost of transportation, lower area and cost of installation, fast and easy installation, deeply sought by customers who have many need transport from one project to another project. Its capacity range 10t/h ~ 160t/h, ideal for small or middle types of projects.
(4). Stationary Asphalts Mix Plants
Stationary asphalt mix plant is a machine without mobile frame chassis, with characteristics of stationary, batch mix, precise aggregate batching and weighing; classic model, wide application, highly cost-effective, best-selling. Its capacity range 60t/h ~ 400t/h, ideal for middle and big projects.
YUESHOU Machinery manufactures several types of asphalts batch mix plants with capacity from 10-400t/h, including classic stationary type –LB series, mobile type–YLB series
Main Components of Asphalt Batch Plants:
The asphalts plants are mainly composed of the following parts:
1. Cold aggregate supply system
2. Drying drum
3. Burner
4. Hot aggregate elevator
5. Dust collector
6. Vibrating screen
7. Hot aggregate storage hopper
8. Weighing and mixing system
9. Filler supplying system
10. Finished asphalts storage silo
11. Bitumen supplying system.
Working Process of Asphalt Batch Plants:
1.Cold aggregates feed into Drying drum
2. Burner heating the aggregates
3. After dried, the hot aggregates come out and enters the elevator, which transports them up to the Vibrating screen system
4. Vibrating screen system separate the hot aggregate to different specifications, and store in different hot aggregate hoppers
5.Precise weighing of the aggregate, filler and bitumen
6.After weighing, the hot aggregate and filler are released to the mixer, and the bitumen will be sprayed in the mixer
7.After mixed for about 18 – 20 seconds, the final mixed asphalts is discharged into the waiting truck or the special finished asphalts storage silo.
