Perusahaan Asphalt Mixing Plant

Haomei Machienry is a perusahaan asphalt mixing plant with professional technology and service based in China. Asphalt mixing plant refers to equipment that dries, heats, screens, and measures sand and gravel, adds appropriate fillers, and mixes them with hot asphalt liquid in a certain mixing ratio to form asphalt mixtures. The production process is automatically controlled by a computer, the mixing process is improved to reduce fuel consumption, efforts are made to eliminate pollution such as exhaust gas and dust, and strengthen environmental protection. Since the 1970s, the recycling of old asphalt mixtures and the development of corresponding production equipment have been generally emphasized.

The sand and gravel supply and drying heating of the batch-type asphalt mixing plant equipment are continuous, while the mixing with the hot asphalt liquid is batch-wise. The sand and gravel materials are separately stored in each hopper of the cold silo, and after initial volume measurement, they are sent to the drying cylinder by a belt conveyor for drying and heating. There are many long blades on the inner wall of the drying cylinder, the cylinder is slightly inclined towards the discharge side, and the discharge end is equipped with a burner. When the cylinder rotates, the sand and gravel are continuously lifted and scattered by the long blades, and move forward, contact with the flame sprayed by the burner, dry and heat, discharge out of the cylinder, and then be sent by the bucket elevator. The screening machine is used for screening, and stored in each hopper of the hot bin, and then discharged into a weighing hopper with an electronic scale according to the specified mix ratio for stacking and weighing. At the same time, the stone powder is conveyed and weighed by the conveyor, and the hot bitumen liquid is pumped and measured by the bitumen pump. After the various materials are dosed, the hot sand and stone material and stone powder are first discharged into the mixer for dry mixing, and then the hot asphalt liquid is sprayed on the hot material for mixing. The agitator of asphalt mixing plant company is a two-shaft forced type. The two shafts rotate in opposite directions. There are several pairs of mixing blades on each shaft. After the mixture is fully stirred, the bottom discharge door is opened and discharged. The exhaust gas and dust are recovered through the pipeline, and discharged after being purified by the dust removal device.

The main feature of continuous asphalt mixing plant equipment is that hot sand and gravel and hot asphalt liquid are continuously metered and supplied, continuously mixed and discharged. The agitator of perusahaan asphalt mixing plant is long, equipped with multiple pairs of mixing blades installed in a spiral direction, one end of which feeds continuously and the other end continuously discharges. Generally equipped with automatic control devices, automatic production can be realized, and the productivity is high, but it is difficult to accurately control the coordination.
