The asphalt concrete mixing station, type QLB800—HQB500, is our asphalt concrete mixing equipment with independent intellectual property rights by independent development, and on the base of consulting the overseas advanced technology. It is of high automation in operation, of accurate measurement, of modular design, of reasonable and compact structure, of convenient operation and maintenance, and of energy conservation, so the equipment 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 adopts TOLEDO electronic balance and weighing cell. It also introduces advanced devices such as American atmospheric blowback 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 equipment is not only ideal for producing high-quality asphalt concrete for the high-grade highway construction at home and abroad, 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, inclined belt conveyor, heating tube system, oil burner system, atmospheric blowback baghose precipitator, chain bucket elevator, hot aggregate vibrating screen, hot aggregate storage bin, hot aggregate metering, mountain flour storage bin, mountain flour metering, asphalt metering, agitator kettle, hoist and traction rail machine, finished product silo and 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 is either by computer control or by electric wheel for manual control.

Luda Asphalt Mixing Station, pioneers accurate metering control technology, creatively improving the metering structure and control measures of asphalt, powder, and aggregate, realizing dynamic accuracy control, strictly optimizing various performance, reducing measurement error, totally meeting with the international standard, and effectively reducing production costs. At the same times, with the coordination of its mixing console of extraordinary power, it makes engineering works flexible, high effective and safety. It’s just because of our persistent pursuit for the leading technology and repeated trials without considering our costs that we can achieve remarkable results, and gain a larger share of market.
