How to Reduce Cost of Asphalt Manufacturing Plant

May 25, 2023

In the construction of asphalt pavement, the asphalt plant equipment is the key equipment to ensure the construction quality and improve the efficiency, and it is a very critical part of the pavement construction process.

The hot mix asphalt plant s mainly composed of batching system, drying system, combustion system, hot material lifting, vibrating screen, hot material storage bin, weighing and mixing system, asphalt supply system, powder material supply system, dust removal system, finished product silo and control system, etc.

Cutting the production cost of asphalt mixture should start from the batching and drying stage. This includes precise dosing of aggregates and bitumen, and reduced fuel consumption by achieving optimum combustion and maximizing heat exchange between combustion gases and aggregates.

Unreasonable ratio of asphalt mixture

The mixing ratio of asphalt mixture is the target mixing ratio and the production mixing ratio. The target mix ratio controls the conveying ratio of sand and gravel cold material. The production mix ratio is the mixing ratio of various sand and gravel in the finished asphalt product specified in the design. The production mix ratio is determined by the laboratory, which directly determines the grade standard of the finished material.

In order to further ensure the production mix ratio and set the target mix ratio, the production can be adjusted appropriately according to the actual situation. When the target mixing ratio or production mixing ratio is inappropriate, the stone materials stored in each metering of the mixing station are out of proportion, affecting the asphalt mixture output.

The high moisture content of sand and stone

The production capacity of the drying drum of the asphalt mixing plant matches the equipment model. When the water content of sand and gravel is too high, the drying capacity will decrease, and the quantity of sand and gravel supplied to the metering warehouse to reach the set temperature per unit time will be low.

Low combustion value

Asphalt manufacturing plants have certain requirements for fuel, generally iesel, heavy diesel or heavy oil. During the construction process, some production enterprises burn mixed oil with low combustion value and low heat, which seriously affects the heating capacity of the drying cylinder.

Asphalt concrete production requires mobility, and the use of small mobile asphalt manufacturing plant greatly reduces the cost of work. Haomei mobile asphalt batching plant has a production capacity of up to 80 tons per hour, which is sufficient to meet the needs of small-scale projects and can be directly operated on the construction site and relocated with the project.
