Regarding asphalt mixing plant operation, the cost can be cut while the efficiency lifted with the following measures:

1. Equipment System Retrofitting: Retrofit the equipment system to reduce operating costs. For example, the combustion system can be transformed into a low-pressure atomized heavy oil combustion system to improve fuel utilization and reduce fuel costs. In addition, the modification of thermal oil heating can also reduce operating costs.

2. Stockyard Management: Plan the stockyard properly to cut transportation costs. Choose appropriate raw material suppliers to ensure the quality and supply stability of raw materials.

3. Production Management: Formulate reasonable production plans to reduce equipment idling time and energy consumption. Strengthen the daily maintenance of equipment so as to extend its service life and cut maintenance expenses.

4. Upgrade Product Design: The updated product design would bring about less raw material (sand, stone etc.) waste, lower production costs, with product quality and competitiveness lifted.

5. Enhance Operator Skills: Provide operators with more training to enhance their equipment operating and maintenance skills, so as to reduce equipment failures and accidents while improving production efficiency.

6. Introduce New Technologies: Introducing new technologies and equipment would result in higher production efficiency and product quality, as well as lower production costs.
