Asphalt Drum Mix Plant

The asphalt drum mix plant is a specialized type of asphalt production equipment used for efficiently producing asphalt mixtures under specified temperature ranges from 150°C to 220°C. The basic principle of a drum mix asphalt plant involves the simultaneous mixing of aggregate materials and asphalt in a continuous process. Therefore, it is also named after a continuous asphalt mix plant. The plant consists of a rotating drum, often referred to as a drum mixer, where the materials are heated and mixed , which has simplified the working process. It is suitable for projects that have continuous asphalt demands, like highways, roads, airports, parking lots, etc. Check applications of the drum mix plant below.

Temperature of Asphalt in Different Fields of Application

The temperature of asphalt in different application areas will be different, the following are some common application areas and the corresponding asphalt use temperature range:

  • Road paving: In road construction, the asphalt mixture is used to pave road surfaces. Generally speaking, the temperature range of asphalt mixture during construction is usually between 120°C and 165°C.
  • Bitumen roof waterproofing: In the construction industry, bitumen is commonly used as a roofing waterproofing material. Thermoplastic asphalt (SBS or APP modified asphalt) usually needs to be heated to a temperature between 180°C and 220°C.
  • Asphalt Concrete Repair: During pavement repair and patching, asphalt concrete is often used to fill damaged areas. The temperature for patching asphalt concrete is usually between 120°C and 150°C.

Asphalt Batch Plant VS Drum Plant

As we all know, the asphalt drum mix plant process working is different from the asphalt batch plant. They adopt different working principles. Here are the main characteristics of them. Check the details of the batch plant vs drum mix plant below.

Asphalt Batch Plant
Asphalt Batch Plant
  • Batch mixing way.
  • Drying in the dryer drum, mixing in asphalt mixer alone
  • Heating aggregate at the bottom of the dryer drum.
  • Hot aggregate would be weighed again in the mixing tower.
Drum Mix Plant
Drum Mix Plant
  • No intermittence during the production.
  • Drying and mixing in the same dryer mixing drum.
  • Heating aggregate at the head of a dryer drum.
  • Hot aggregate needn’t be weighed twice a time.

Reasons for Using Our Asphalt Drum Mix Plant

  • 1. AIMIX asphalt drum mix plant has various models with large production capacity ranging from 20 t/h to 80 t/h.
  • 2. The burning area of our dry drum is adopts anti-weary and anti-materials to prolong service life. The drying mixer drum has a reasonable structure to ensure high thermal efficiency and avoid heat loss.
  • 3. The mineral filler has arch broken device to avoid powder congestion. The old and new powder is weighed with the superposition method in proportion. The recycled powder from dust collectors can improve material availability and reduce environmental pollution.
  • 4. The drum mix plant has modular design, which has quick installation and convenient transportation.
  • 5. The conduction oil system adopts international famous brand burner to guarantee accurate asphalt heating temperature.

The Working Principle of Continuous Asphalt Mixing Plant

  • First, the cold aggregate, asphalt, and mineral filler are weighed respectively.
  • Then the cold aggregate is conveyed to the dryer drum. Meanwhile, the mineral and asphalt are also delivered to the periphery of the inner drum.
  • After the cold aggregate is heated, the hot aggregate will flow into the drum periphery. Therefore, the materials are mixed continuously.
  • The repeated processes are lasting all the time. The drying method of cold aggregate adopts a downstream mode.
  • The finished products are poured from the drying mixer drum, which is delivered to the construction sites.

Main Systems of Asphalt Drum Mix Plant

1. Cold aggregate supply system

The cold aggregate supply system consists of a cold aggregate hopper, aggregate hopper, cold aggregate vibrate screen, aggregate conveyor, belt conveyor, etc. The inner side of our cold aggregate hopper is equipped with a filter. The aggregate in the bin can be cut automatically. The discharge door is mounted with an alarm device. There will be an alarm when the aggregate is underfilled. The vibration screen can filter the cold aggregate of large particle size, which can avoid heat loss during the production process. The aggregate feeder has standard modularization with fast installation and transportation. The cold aggregate system has frequency control with automatic adjustment in synchronous proportion.

2. Drying and heating system

The drying and heating system is the most important part of the drum asphalt mix plant. The moisture of cold aggregate is removed through the drying system, which can ensure the aggregate is mixed with asphalt. It mainly has two devices, including dryer drum and burning. The dryer drum of drum hot mix plant is used to dry the cold aggregate. The insulating layer of dryer drum can reduce heat loss and energy consumption, which improves heating efficiency. The outlet of the dryer drum has temperature measurement device, which can control the cold aggregate temperature automatically. The burner is used to provide the heat source for the asphalt plant drum heating. Our burner has fuel burner and coal burner, which can ensure sufficient heat.

3. Weighing System

The weighing system is composed of aggregate weighing, filler measuring, and asphalt weighing. The aggregate weighing device adopts a famous weighing sensor, which can measure accurately and compensate for errors automatically. It has reasonable weighing orders to prevent partial load. The filler weighing device uses screw conveyor weighing. The filler weighing hopper has an arch broken and a pressure relief device. The asphalt weighing adopts a two-stage anti-overflow protection device. The asphalt is measured twice to ensure accurate weighing.

4. Dust collecting system

The function of the dust removal system is to reduce the dust discharge concentration and protect the environment. The multistage dust collecting system can realize dust collecting in stages, which can improve raw materials availability and ensure finished product quality. The outside of the dust remover has an insulating layer to avoid bag condensation. The inlet of the bag dust remover has a temperature protection device. The protection includes overheating protection, cold air protection, and overrun temperature protection, which can avoid bag damage.

5. Electric control system

The drum asphalt mix plant portable has electric control system. Most components are operated through the control system. The operation can be carried out through finger touching in the control panel and computer. The electric control system can be controlled automatically, semi-automatically, and manually, which is convenient for users to operate and maintain. What’s more, the electric control system improves the automatization of the asphalt drum mix plant.
