Different Types of Hot Mix Asphalt Plant for Sale

We manufacture a series of asphalt plants for varied needs of clients, be it stationary, mobile, batch process or continuous process. Each type of hot asphalt mixing plant is designed to fit a particular job site and job requirement.

1. Batch vs. Continuous Process

Batch type hot mix plant is a widespread type of asphalt production plant in which hot mix asphalt is produced in batches. That is, the heating and drying of aggregate and the mixing of aggregate, mineral filler and liquid asphalt are periodically performed. Every 45 to 60 seconds a complete batch is produced. The batch mix plant ensures a flexible production and a high level of quality since the mixing is forced. It is especially suitable for dealing with special products such as porous asphalt and high RAP content that require a higher level of quality control.

Continuous process is carried out in a drum mix plant, and the mixing and drying of aggregate and liquid asphalt take place in a drum dryer. The hot drum mix plant has simple structure, compact layout and easy operation, making it ideally suited for simple job.

2. Stationary vs. Mobile

Stationary asphalt plant is mostly used for municipal engineering and high-grade highway construction, which is rarely relocated. The process can be a continuous mixing or batch mixing type process depending on your production requirements. You can choose from our ALQ40-320 (batch process) and ALT20-80 (continuous process).

Mobile hot mix plant allows you to move from job site to job site easily and quickly as mounting on a towable chassis. It is ideal for urban and rural road construction as well as general road maintenance. We have a range of models for you to choose from, including ALYQ40-160 (batch mix) and QLYT20-80 (drum mix).

Common Components of Asphalt Hot Mix Plant

• Cold feed unit – cold aggregate is fed in the hoppers of the cold feed unit where it is metered in the desired proportions.
• Drum dryer – aggregate is transported into a rotary dryer to reduce moisture content.
• Bitumen supply system – liquid asphalt cement is stored in a heated storage tank. It is pumped to an asphalt bucket where it is metered to achieve the required aggregate-to-asphalt ratio.
• Dust collector – bag filter system for clean production and environmental protection.
• Control system – automatic control system is designed to control all the operations of the plant.
• Storage silos – the finished product is stored in storage silos which are placed at a certain height for convenient truck loading. The silos are insulated and can be heated to prevent heat loss.

Hot Mix Asphalt Plant Working

Hot mix plant is one of the key units for road construction, and its performance directly affects the quality of asphalt pavement. The plant comprises several devices and systems to produce various hot asphalt mix efficiently and economically. The working of hot mix asphalt plant consists of a few main procedures:

1. Cold aggregate is metered in the hoppers of the cold feed unit and then transported into a drum dryer by a belt conveyor.
2. The hot aggregate from the dryer is dropped into a bucket elevator and transferred into a set of vibrating screens, where it is separated into four different sizes.
3. At the same time, liquid asphalt in the heated storage tank is pumped to an asphalt bucket and weighed through load sensors in the weigh hopper (batch type).
4. The filler is weighed in the weigh hopper where the recovered fines and imported fines can be separately controlled, and then dropped into the mixer by gravity or fed into it by a screw conveyor.
5. Aggregate is dropped into the mixer and mixed for a period of time. Next, liquid asphalt is mixed with it to produce hot asphalt mix. The total mixing time is generally less than 60 seconds.
6. The hot mix is stored in a hot storage silos or directly transported to the job site.
