First，the cold aggregate, asphalt and mineral filler are weighed respectively. The batch mix plant process begins when the aggregates is placed in appropriate bins of the aggregate feeders. The aggregates are then transferred to the drying drum by means of a conveyor. Drying drum is equipped with flights internally to promote drying efficiency. Once the aggregates leave the dryer, they are transferred to vibratory screen which does the task of separation of aggregates according to the size and the aggregates are dropped into the separate hot bins.
Asphalt Mixing Plant is a cluster of electronic and mechanical gear. Reused materials, aggregates, or various sort of added components are mixed, heated, dried and blended with a binder
Asphalt mixing plant belongs to large equipment, so there are many points we should pay attention to the safety while using. So the operation procedures are significant to operators and project manager. The operation procedures of asphalt mixing plant can be divided into two parts, about the asphalt mixer and the operation, here let me introduce them as follows.
Since entering the 21st century of modern construction ,concrete mixers are widely used.concrete mixer not only reduce the labor intensity, but also improve the quality and efficiency of the concrete , our country has made agreat contribution to establish the infrastructure of construction machine market. Concrete mixer industry has also become the country’s national increased industry.
Diesel concrete mixers are mobile type, very convenient to move anywhere. The drum rotates in one direction for mixing and in the opposite direction for discharging the concrete. There are two types of blades attached to the inner walls of the drum. One set drags the concrete upwards and toward the center of the mixer when the drum rotates in one direction; the second set of blades pushes the concrete toward the opening when the drum rotates in the other direction. The blades have a spiral arrangement to obtain the desired effect for discharging and mixing. Diesel concrete mixers are suitable for mixing plastic and low-slump concrete. It is widely used in roads, bridges, water projects or other industrial and civil projects, specially most popular in tight-electricity countries.
Asphalt mixing plant, also known as hot mix asphalt plant, it is a very significant machine equipment in road construction. The selection of asphalt mixing plant should be based on the amount of engineering, engineering progress and other requirements to determine the production capacity requirements, and accordingly to select the appropriate model.
Cold Mixing Asphalt Plant . Cold mix asphalt is a combination of mineral aggregate and emulsified or cutback asphalt with additives. Aggregates can be made with virgin materials or reclaimed asphalt pavement, also known as asphalt millings. The latter option is commonly used when trying to save money. Cold mixes can be made on site or at a central location and then transported to the site. The flexibility to create this type of asphalt off-site is particularly useful for remote roads.
Concrete mixing plant work is actually more dangerous, especially for an untrained person, a little attention, it is possible to produce illegal operations, and then produce danger, then those are illegal operations?
The self-falling concrete mixer has a long history, the self-falling concrete mixer is also called the free-falling concrete mixer , is also the concrete mixing plant commonly used concrete mixer host, with the development of industry, the self-falling concrete mixer has what characteristics?
Screw conveyor is an important part of concrete mixing plant, and its working efficiency directly affects the project progress. Toady, haomei machinery will talk about how to improve the working efficiency of screw conveyor and the factors that influence screw conveyor output efficiency in this article.
In this article, haomei machinery technical personnel will introduce some precautions about how to choose a suitable concrete batching plant to our customers.
