basic configuration

INTRODUCTION

       QC series asphalt mixing plant is a equipment suit to mix the asphalt macadam,asphalt concrete,tar sands,modified asphalt mixture etc for the project of high way,municipal engineering,airport.

一、Cold feeder system

1、Cold bin

The cold aggregates storage bin adopts single fission structure design. Modular design,installation layout according to the site situation.Equipped with maintenance platform, extra-large grid network,lack of material testing,the outer wall has a broken arch vibrator sand storehouse.

2、Feed belt conveyor     

cold aggregates storage use the skirt belt convey feeding,Each bin individually controlled by frequency converter and adjustment the size of cold bin exit door to adjust the feeding flow. ensure uniform feed feed rate,measurement,high accuracy,whichcan realize automatic control,belt feeder used no excuse,high strength,high wear—resisting rubber skirt belt.

3、Aggregate belt,feeder belt.The belt machine adopts special wear-resistant rubber belt without interface. The supporting roller of the belt machine adopts the built-in oil-sealed bearing for long-term work without lubrication. Belt inside and outside two sides are equipped with a sweeper to keep the belt clean. Both sides of the belt are equipped with automatic correction, anti-deviation device and pull rope emergency stop switch to operate safely and reliably.

The feeder beIt adopts seamless,high strength,high wear-resisting rubbe belt.The oil seal of belt feeder roller and roller bearing with built -in type.It can work long-term and needn't to be lubricated.The belt feeder equipped with outside clean shave feeder,and belt tension adjusting device.It can reduce the damage of the belt caused by aggregate adhesive.

二、Dry heating system

1、Drying system

  The drum adopt the current heating form,The drying System using an integrated thermal system design technology,makes the system guarantee Stable Jobs and hasthe best thermal efficiency.

2、Burner

   Burner adopted lhe latest fire control technology in the world . With the change of oil pump, fan speed to realize the regulation of the proportion of fuel and air volume. Use the advanced way of Iow pressure without retum oil supply. Adhering to the European product safety,environmental protection energy saving.

三、Bag dust removaI system

    Adopts the primary inertial dust removal and secondary bag dust collector.The bag use the Dupont“NOMEX“bag,weight is 500 g/m2,Carbon concentration≤20mg/Nm3(standard working condition)blackness Salinger I level.

四、The main building-mixing system

1、Hoist

 Adopt wear-resisting alloy double coin chain structure .Elevator drive reducer with prevent reverse device,linear speed is low,stable running,low noise,less wear.

2、Vibration screening

It is the vibration motor driven straight-line vibration screen. Vibretion motor adopts imported Italian brand,free maintenance .Screen used in a drawer of push-pull installations,with automatic spring tension,easy to change,longer life.

3、Hot aggregate storage bin

Super hot material storage warehouse,with rock wool insulation,high and low level indicate,cylinder door with damping block control,prevent jam the door.

4、Metering system

Aggregate,powder and bitumen are using imported three pressure sensors. Measurement methods is accumulating measurement. Automatially divide the whole compensation technology.to guarantee

the measurement more accurate. Feeding door bearing using free maintenance since the shaft sleeve, greatly reduces the railure rate. and Longer service life.

5、Mixing system

The mixer blades and wear-resisting lining board are made with alloy cast steel,high abrasion resistance.On the mixer equipped with additives(SMA)and regeneration material incoming interface,easy to user extensions additive equipment and regeneration equipment..

五、Powder supply system

1、Powder elevtor

With double row high-strength wear-resistant ring chain .Elevator drive reducer with prevent reverse device. Elevator  hopper mouth with special material structure processing. In and out  hopper mouth with wear-resisting backing board.

2、Powder storage tank

Powder hopper is linear monomers double barrel warehouse. Up part is ores powder hopper,down part is recycling powder hopper. Powder storehouse capacity can be customized according to user needs.The ores powder hopper with galls on powder device. At the bottom of the cone powder storehouse have spirit to break the arch,prevent powder arch.

3、Powder conveying screw

六、:finished storage silo

Compostie insulating layer

Storage silo it’s a rectangle hopper , total 50/100tons vessel. Discharging agate Height 3.8m (up to client  )in-side have rock wool insulating layer warranty temp drop 5% when full-up, discharging gate and both side equip electric heater ,storage silo design principle anti-segregation ,equip Hi-material position detector ,auto-alarm after full -up

七、Pneumatic system

   Consist of :0.6 m3 air storage tank ,two air compressor buffer tank ,pipeline ,cylinders and connecting kits .

八、control system

central control room

500mm×2200mm×2400m  


 Business questions and answers: 

                                                                                                                                                                                                                                                                         (1) Question: what is the output on the parameter table? 

(1)Question: what is the output on the parameter table? 

Answer: the output on the parameter table is the output under working conditions. Standard atmospheric pressure under working conditions: 760 mmHg. Ambient temperature: 20℃; Specific gravity of aggregate: 1650kg/m3; Moisture content of aggregate ≤5%; Specific heat of aggregate: 0.21 Kcal/kg℃; Powder content: 5%; Asphalt content: 5%.

Answer: the combustion machine of the equipment has coal burning type, fuel oil type and gas type combustion machine, burn coal, diesel, natural gas respectively, the user can customize combustion machine according to the need.

 (3) Question: what is the power supply voltage and frequency? 
Answer: when the standard power supply voltage of the equipment is 380V, the frequency is 50Hz. If there are special voltage requirements, the delivery time will be appropriately extended and the customization fee will be increased. 

(4) Question: how long is the equipment warranty period? 
Answer: the warranty period is 13 months from the date the equipment leaves the factory. 

(5) question: how is it transported? 
Answer: our company is 80 kilometers away from xiamen port, the product is sent from xiamen port, the cost is about 2000 yuan /40 high container. 

(6) Question: what are the configurations of the products? 

   Answer: The fixed asphalt mixing equipment consists of a cold feeder system, a dry heating system (including a burner), a dust removal system, a main building system, a pneumatic system, and a control system. The powder supply system, the finished storage siloIs and the asphalt tank are optional items, and the secondary dust removal system can be selected as a bag filter or a water dust remover, and the user can select according to the needs.
