45 seconds mixing cycle batch type asphalt mixing plant with Schneider electric parts

?

1.0 ?Fine material (filler) storage supply system

System has 2 storage bins, one for mineral powder and another for waste powder, each bin has damped rotation type level indicator and straight ladder with safety ring; Safety rail, dust collector and safety valve are set on bin top; arch breaking air cushion is installed at [pyramid] part of bin outlet to prevent filler from backlogging. Filler bin and waste powder bin are equipped with screw conveyor (Italia WAM) to send filler directly to weighing hopper.

?

1.1 Filler(mineral powder) bin

By air force, filler is sent into storage bin through pipeline. Audible and visual alarm will be given when filler is full, reminding operator against ash overflow. Filler bin is equipped with screw conveyor(Italia WAM), which send the filler directly to filler weighing hopper.

* Type: Stand barrel type

* Capacity: 30m3

?

1.2 Waste powder storage bin

Waste powder from bag type dust collector will be sent into waste storage bin through screw conveyor and filler hoister. Waste powder storage bin is equipped with screw conveyor (Italia WAM) which send waste powder directly to waste powder weighing hopper.

*Type: Stand barrel type

*Capacity: 30m3

?

1.3 Waste powder hoist

Hoister is hopper type, using belt to hoist, with characteristics of smoothing running without noise, fast hoisting speed and high efficiency. There is chain spring tensioning device at the both sides of hoister bottom; Platform is installed at top for maintenance of hoister.

* Type: Hopper-type, gravity discharging

* Capacity: 25t/h

* Drive: Cycloidal pin gear speed reduce

* Power: 4 kw

1.4 Screw conveyor

?

* Filler weighing screw conveyor: 5.5kw

* Waste powder weighing screw conveyor: 5.5kw

* Waste powder conveying screw conveyor: 3 kw×2 sets

* Waste powder discharging screw conveyor: 3 kw×1set

Tip: The connection (outlet) of filler storage bin is only for filler in bulk, if filler hoist is required additionally, tell us when ordering.



2.0 Pneumatic control system

Pneumatic control system is composed of air cylinder, air valve, pressure adjustment valve, oil-water separator, oil sprayer and high pressure tube. System air source adopts screw air compressor, with 2 compressed air storage tank, in which 1 is used for the whole mixing tower, bag type dust collector, finished product bin, another for fuel atomization of burner.

* Screw air compressor: XNB-30G

* Air displacement: 3.6m3/min

* Pressure: 0.6~0.7Mpa

* Motor power: 22kw

* Capacity of air storage tank: 0.6m3×2pcs
