Asphalt mixing plant machinery purchasing tip

The biggest cost for road construction proves to be the cost of asphalt mixing plant machinery. And model choosing is the first step in purchasing asphalt mixing equipment. Correct choices helps not only to reduce the plant cost, but also to avoid unnecessary maintenance expenses in the future. Therefore, you must select a model scientifically and rationally according to the annual output. A larger model leads to increase in the input cost and reduction in the effective use efficiency, while a smaller model indicates insufficient output, prolonged operation time and exhausted workers.Then how to choose a model of asphalt plants? You need to do math correctly and reasonably as below.

Formula of the hourly production of an asphalt batching plant:

Hourly output of asphalt mixing plant machinery= annual demand output/year effective construction June/monthly effective sunny day 25/day work 10h (the prime time for effective asphalt construction is 6 months each year, the effective monthly construction days are counted as 25 days, and work every day Time is calculated in 10h).

Then could you choose a model just fits the hourly output above? NO. All asphalt plants have a theoretical productivity, usually larger than the practical output. You should choose a slightly larger model. Due to various factors such as raw material specifications, moisture content, etc., the actual stable output of asphalt mixing plants is usually only 60% to 80% of the product model. If the output is further increased, the mixing uniformity, gradation and temperature stability of the mixture will be affected. If it is to produce rubber asphalt or modified asphalt mixtures such as SMA or after the rain, the rated output will also drop to a certain extent. The main reason is that the mixing time is prolonged, the stones are wet after the rain, and the temperature rises slowly.
