Steps of mixing materials with asphalt

Bitumen, a black or brown petroleum-like material, has a viscosity ranging from a viscous liquid to a glassy solid. It can be obtained as a residue separated from natural deposits. Bitumen consists of hydrogen and carbon compounds with small amounts of nitrogen, sulfur and oxygen. The preparation of mixed materials for mixing with asphalt is done in several steps:
Prediction: According to the asphalt recipe, the individual components of the aggregate are weighed. Usually this is done using a belt scale, since the material must go to the next step in a continuous flow.

Bitumen, a black or brown petroleum-like material, has a viscosity ranging from a viscous liquid to a glassy solid. It can be obtained as a residue separated from natural deposits. Bitumen consists of hydrogen and carbon compounds with small amounts of nitrogen, sulfur and oxygen. The preparation of mixed materials for mixing with asphalt is done in several steps:
Prediction: According to the asphalt recipe, the individual components of the aggregate are weighed. Usually this is done using a belt scale, since the material must go to the next step in a continuous flow.
Drying: In a rotating drying drum, the components of the aggregate are dried at a temperature of 140-190 ° C. After drying, the components are sieved and stored several dozen separately.
Weighing: Since drying can change the previous particle size distribution curve, a final weighing is necessary before adding the individual aggregate components to the mixer. This also allows for quick changes in recipes. The binder (bitumen) is kept in a heating box and added to the mixer according to the measured flow rate.
Mixing: The mixer can work continuously or in intervals. Interval mixers use a loading screw to feed the aggregates, and the binder is injected synchronously into the mixing chamber. For very high volumes, continuously operating mixers are used that cannot quickly adapt to changing volumes and formulation needs.
Dispatch: The mixed material is stored in a heated silo and there are usually several chambers to store different formulations.

    More Asphalt Processing

    For road construction machinery, the following is mainly about the asphalt mixer in road construction machinery equipment. Because it is the key product of Wuxi road construction machinery manufacturers, it is necessary to carry out comprehensive training and mastery, so as to ensure meticulousness and practicality, and not ignore any knowledge points.
    1. In road construction machinery, is there any difference between asphalt mixing equipment and asphalt concrete mixing equipment?
    The answer given by Sinoroader Group manufacturer to this question is no, that is, there is no difference between asphalt mixing equipment and asphalt concrete mixing equipment. They refer to the same type of equipment, but they are different in name. It can be said that they are two names for the same type of equipment, and there is no difference in essence.
    2. During the operation of the asphalt mixer, there is a sound in the mixing pot. What’s the matter?
    In the view of Sinoroader Group, there are two answers to this question. One is that the mixer arm on the asphalt mixer is not good or damaged. The second is that the wear-resistant lining in the mixer is damaged, which leads to this problem.
    3. What are the dust removal devices in the asphalt mixing equipment?
    In the asphalt mixing equipment, for its dust removal device, Sinoroader Group believes that the key is to use the dry ash removal method, because it can facilitate the collection of raw materials. In terms of its dust removal equipment type, there are filter dust removal equipment, centrifugal fan dust removal equipment and force dust removal equipment, etc., which can all be used well.
    For the asphalt mixer and asphalt mixing equipment in road construction machinery, I believe that through the practical discussion of the above relevant content, everyone can master it well and master it, so that in practice, they can have new gains and benefit a lot from it.
