Product Features

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.
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.
6.Bitumen Supply System
Volume and number of bitumen tanks is customizable according to user requirement.
Heat transfer oil heating type, heating equably.
