1.Cold Aggregate Feeding System
a.SAP100 asphalt mixing plant consists of 4 units of cold aggregate bins. Each cold aggregate bin includes one set of variable speed discharge belt feeder.
b.There is one set of alarming device in each cold aggregate bin in case of no aggregates supplying during operation.
c.The belt feeder adopt variable speed to discharge the aggregates.
d.Each aggregate bin has a screen to prevent the big size being discharged in the collecting belt, then going to the drying drum. This device can prevent the heat losing from the drum, which can avoid the screen mesh being blocked.
e.The Sand bin adopts vibrating device to prevent sticky aggregates hard being discharged into the belt feeder.
Technical parameters of cold aggregate feeding system:

Feeding belt


frequency converting control

Hopper wall vibrator



Horizontal belt conveyor



Inclined belt conveyor



Alarming device of no aggregate

4 sets


2.Drying System
a.The drying drum adopts four wheel friction to work.smooth and reliable transmission, motor is started by reducing voltage, insulating layer adopted in outside of drying drum. And drying surface is packaged by stainless steel.
b.Roller ring connected to the barrel USES the word "of" plate, effectively prevent roller heated thermal stress deformation.
c.Burner choose well-known brands (opel, riello, black &decker, etc.), more can choose such as coal or natural gas combustion medium.
d.Cylinder and ejecting blade of heat-resisting steel manufacturing, longer life.
Main parameter of Drying drum:

Rated output


5% moisture content

Driving power



cylinder size



Fan power


fuel burner

Burner fuel consumption


To adjust than 1:3

3.Hot Aggregate Elevator
a.The hot aggregate elevator adopts flat link chain to drive, the chain bucket has protective device. Location of input and output adopt design of antiabrasion structure.
b.The non-return device adopted in drive wheel can prevent the chain from reversing.
c.Non-return device adopt noiseless design.
d.The motor of hot aggregate elevator is 11kw.The capacity of hot aggregate elevator is 110 ton/h.



4.Mixing Tower
a.The vibrating adopts four layer's design. The outside of screen is closed by protective cover, so that dust won’t going out from the screen. Uniaxial external structure make the maintenance work more convenient.
b.The size of mesh can be custom-made according to client’s special requirements.
c.Hot aggregate storage bin has level indicator,the hot aggregate storage bin has big volume so that feeding aggregates will be more stable.
d.Hot bin have waste, material overflow device, prevent waste, material overflow congestion vibration sieve.
e.Aggregate weighing system and filler weighing system all have anti-dust device.
f.The bitumen adopt secondary weighing, which will be more accurate. The usage of spiraling pump discharge the bitumen into the mixer uniformly.

g.The asphalt mixer adopt twin shaft design, pneumatic discharging finished product. Surrounding of discharging gate including attemperator.
h.The high locating structure can guaranty the dump truck loading the finished products easily.
Main technical parameters of Mixing Tower:

Vibrating Screen


4 decks, single shaft

Aggregate weighing hopper



Filler Weighing Hopper



Bitumen Weighing Hopper



Mixer Capacity



Mixer power



Bitumen Spiraling Pump


Three-Screw Pump

5.Dust Collecting System
a.Adopting primary dust collecting by gravity, secondary dust collecting by water filter dust collecting design,which is more environmentally friendly.
b.The bulky grain can be recycled after primary dust collecting.
c.The import and export of bag dust collector has a temperature measuring device, real-time temperature of bag. Dust collecting use high voltage pulse type, effective, long service life.
d.The dust can be discharged or reused after secondary dust collecting,higher environmental standards.
e.Water dust collecting is optional in secondary dust collecting.
Main parameter of Dust collecting system:

Fan power


electric throttle

Dust cover



Dust collecting screw



Exhaust emission concentration


standard conditions

6.Bitumen System
Asphalt by heat conduction oil heating, convenient operation, safe and reliable. Asphalt aging.
Heat conduction oil central heating, more economical and practical.
The double-deck asphalt piping,the heat conduction oil heating between the interlayer.
Optional direct heating asphalt tank.
Main parameter of Bitumen system:

Bitumen tank capacity


Optional Number and capacity

Thermal power
(Heat conduction oil furnace)

300000 kcal


Circulation pump


Three screw pump




7.Filler System
Mineral powder is centralized storage by storehouse,and equipped with centralized dedusting, no dust overflow.
Powder storehouse is equipped with high and low material level meter, real-time detection powder capacity.
Powder bin and temporary storage is equipped with Arch breaker.

Main parameter of Filler Supplying System:

Powder bin volume


with high and low material level meter

Powder hoist



Powder temporary storage



Metering screw 



8.Electronic Control
a.We adopt famous international brand (like SIEMENS, Schneider, ABB) electronic elements, working performance is reliable and stable.
b.The adoption of PLC and Industrial computer make the operation more easy.
c.The Multifunctional printer can print and storage date anytime.
d.Big capacity formula function can meet client’s various need.
e.Optional remote fault detection.
f.Container type control room, strong and durable, economy and beautiful.
g.The Manual/automatic operation can be shifted freely.
h.Control room 4.5x2.2x2.5 (m).
