Macroad - Asphalt Dryer Drum
Asphalt dryer drum is one of the most important component of asphalt plant drying and heating system. The main purpose is to remove the moisture from the cold aggregate and heat them, which can ensure bonding with the asphalt. As we all know, the moisture of cold aggregate should be controlled accurately. Otherwise, it may influence the finished product – asphalt mixture. Therefore, it is essential to choose a best asphalt drum to improve working efficiency in the beginning of the whole process. Here is an elaborate introduction about asphalt drum dryer for sale. Hope it can help you a lot.
Structure of Asphalt Dryer Drum
The structure of the asphalt drum mixer for drum mix plant is composed of a cylinder body, a feeding blade, a rolling ring, a supporting roller assembly, a thrust roller assembly, a driving device, an inlet and outlet cigarette box and a frame. The inner guide plate of the bitumen drum is divided into three sections according to the arrangement: the feeding section, the convection section (the curtain area) and the combustion section.
- Special structure of the inner blade of the asphalt drum for sale; partition arrangement; high heat exchange efficiency.
- The asphalt drum mixer for sale adopts wear-resistant high temperature lifting plate, which has long service life and can’t deform easily.
- Discharging chute have used anti-weary materials to keep long life span.
- The whole body have insulation function. Besides, it has plated zinc sheet to decorate externally.
- It has strong anti-overload capability and high reliability. Thus, the portable asphalt drum mixer runs smoothly with low vibration. Moreover, axial turbulence of the cylinder during operation is not more than 3mm.
- The support roller and raceway are well matched, which can greatly reduce the wear and power consumption. Rollers’ service life is not less than 5000h and rolling rings’ life span is no less than 10000h.
- Specially designed retaining wheel structure can greatly reduce the horizontal thrust caused by the tilting work of the asphalt hot mix plant.
- Gears, bearings and other purchased parts have imported from internationally renowned brands with high configuration.
- Roller ring and supporting roller are made of high quality wear-resistant steel, which is further wear-resistant by heat treatment.
- Safety protection net is set at the coupling and safety protection cover is set at the rotary ring of drying cylinder.
- The bitumen drum in China has set safety protection device to brake quickly in emergency.
- Asphalt drying drum is made of steel plate with good abrasion resistance and heat deformation resistance no less than 16Mn.
- There is temperature testing device at the end of dryer drum to control the aggregate temperature.
