The drying drum of asphalt batching mix plants

The structure of asphalt plant of different brands is different, main performance in the size of drying drum, internal partition, leaf blade layout form, etc.
The size of drying drum: in the drying drum, the aggregate complete heat exchange by means of continuous rolling forward in the material curtain. Therefore, under certain conditions, the length of drying drums can affect the transfer time of aggregate and heat in the drum and the diameter of the drum can affect the area and speed of the shade away. In this sense, the size of the drum is proportional to its drying capacity, namely the large enough size of drum is one of necessary factor to guarantee equipment production.
Internal partition and layout blade: blade of drying drum within special arrangement, points four areas (import area, shade area, radiation zone, discharge zone). The blades are not disposed in each region. The special protective blades, which are installed in the flame area, may be formed between the flame and the drum, reducing heat outward scattering.

The Main Structure of asphalt batch mixing plant

Main Structure of asphalt batch mixing plant:
Main Structure of asphalt batch mixing plant

1.Cold Aggregate Supply System
Bin volume and number is customizable, Separated structure design significantly reduces dimensions for shipping and ensures a high capacity.
Two independent cold feeders and modular design, transport expediently.
Seamless ring belt, high reliability and long life.
Frequency convertor controlled SIEMENS motor, infinite variable speed adjustment, more accurate and energy saving.

2.Drying Drum
SIEMENS motors, hard-teeth reduction gear, friction driving, drum rotating stably.
Optimized lift blade design, make sure heating equably and high energy using ratio.
With 50mm insulating layer and stainless steel skin, avoid heat be lost.

3.Burner
Italy EBICO oil burner imported with original packing, high burning efficiency, diesel, diesel/heavy oil dual purpose or gas as fuel is optional.
With automatic flame failure protection devices for emergency.

4.Dust Collection System
Two level dust collection system (volute casing collector + bag house collector), with high and low temperature protection device for the system security.
Bag house collector using USA Dupont NEMEX bags, heat resisting and long life.

5.Mixing Tower
Both aggregate and filler elevators are equipped with a double ring chain bucket, which is more reliable and convenient for maintenance.
Twin shaft compulsory asphalt concrete mixer (the mixing arm is cross arranged with changeable gridded mixing blade), high mixing efficiency and long life.
SIEMENS motors with hard-teeth reduction gear, most stably and high performance.
Bitumen is sprayed into mixer through a special designed spray bar with high pressure to reduce feeding time and increase mixing uniformity.
Totally enclosed type circular vibration screen, modular design, vibration motor driving, low maintenance and long life.
Double layer much bigger hot aggregate storage hopper can effectively guarantee the continuity of the supply of hot aggregate; with 50mm insulating layer to avoid heat be lost.
