320(QLB4000) Asphalt Mixing Plant

The asphalt concrete mixing station, type QLB800—HQB500, is our asphalt concrete mixing equipment withindependent intellectual property rights by independent development, and on the base of consulting the overseasadvanced technology. It is of high automation in operation, of accurate measurement, of modular design, ofreasonable and compact structure, of convenient operation and maintenance, and of energy conservation, so theequipment can be widely used in the production of high-grade asphalt pavement materials.The equipment adopts central control system of industrial control computer. And its measurement system adoptsTOLEDO electronic balance and weighing cell. It also introduces advanced devices such as American atmosphericblowback baghose precipitator andGermanyoil burner. All these make it have characters of reasonable structure,qualified properties, accurate measurement, high efficiency, and easy operation, and etc. Therefore, the equipmentis not only ideal for producing high-quality asphalt concrete for the high-grade highway construction at home andabroad, but also suitable for roads building by city or county highway bureaus and city municipal corporations.The total equipment is an integrated mixing system composed of collector belt, cold material trundle screen, inclinedbelt conveyor, heating tube system, oil burner system, atmospheric blowback baghose precipitator, chain bucketelevator, hot aggregate vibrating screen, hot aggregate storage bin, hot aggregate metering, mountain flour storagebin, mountain flour metering, asphalt metering, agitator kettle, hoist and traction rail machine, finished product siloand central control room, etc.Specially, mixing station is made up of reasonable equipment group of vibrating screen, aggregate storage bin,aggregate metering, mountain flour metering, asphalt metering, and agitator kettle in vertical layout. Its operation iseither by computer control or by electric wheel for manual control.Luda Asphalt Mixing Station, pioneers accurate metering control technology, creatively improving the meteringstructure and control measures of asphalt, powder, and aggregate, realizing dynamic accuracy control, strictlyoptimizing various performance, reducing measurement error, totally meeting with the international standard, andeffectively reducing production costs. At the same times, with the coordination of its mixing console of extraordinarypower, it makes engineering works flexible, high effective and safety. It’s just because of our persistent pursuit forthe leading technology and repeated trials without considering our costs that we can achieve remarkable results,and gain a larger share of market. Main composing systemsControl SystemThe PC+PLC control system, by independent research and development, has the characteristics of stable and simple operation.Cold Aggregate Feeder SystemSpecial design structure brings it good effects of preventing segregation, reducing resistance and avoiding unusual wear and tear.Drying DrumThe using of design technology of Integrative heating system, gives the best heating efficiency at the same time ofkeeping steady operation.Screening systemIt adopts double oscillating electromotor with maintenance-free design.Mixing StationAccurate measurement, combining with high effective mixing technology, is the guarantee to produce high-qualityasphalt concrete.Dust Removal SystemGravity and bag 2-level dust removal, in 1st level of Ringelmann smoke chart for exhaust smoke density, and withdust content ≤20mg/Nm3Mixed Material Storage SiloSide machine type, underneath type and horizontal type, 3 kinds of silos to choose from.Pneumatic SystemHigh effective, reliable, of low noise, and maintenance freeAsphalt Feeding SystemHeat-conducting oil heating, safety and high effective
