Asphalt batch mix plant and asphalt drum mix plant, which one is better?

Generally, there are two types asphalt mixing plant, batch mix and continuous drum mix; each type has its advantages. Then, how to choose the right one for your project? Here are some tips:

Batch Mix Asphalt Plant

At present, batch mix asphalt plant is the most popular due to

1) Accurate weighing, precise screening and batching. Therefore, the finished asphalt mixture is of good quality.

2) High efficiency, a single batch cycle is about 45 seconds) and large capacity (up to 400t/h).

3)The recipes of asphalt mixture produced by a batch mix asphalt plant can be adjusted easily, thus it produces various kinds of asphalt mixtures.

4)It has wide applications, including highways, airports, national roads, city roads and country roads, etc.

5) Easy operation. Nowadays, most batch mix asphalt plant is automatically controlled.

Continuous Mix Asphalt Plant

1)As is known by its name, a continuous drum mixing plant will produce asphalt mixture in a consistent run once it is started. Aggregate drying, heating and mixing are all taken place in a drum. Compared with a batch plant, a continuous asphalt plant is simple in structure because it has no mixing tower and elevating system; therefore, it required less land, less maintenance cost.

2)However, due to lack of precise screening, it requires precise control over aggregate feeding at the very beginning of a production.

3)Normally, capacity of continuous asphalt plant varies between 20t/h and 100t/h.

4)A continuous asphalt plant required less initial investment compared with a batch mix one (with same capacity).

After all, the aforesaid tips are just for reference. The final decision is up to client. But in general, a batch mix asphalt plant is best for a large and medium-sized road construction project requires high quality asphalt mixture. While a continuous asphalt plant is suitable for small and medium-sized road construction project which has tight investment.
