I. Capacity comparison analysis
Small mixing plants can process 20-60 tons of mixture per hour, which is suitable for county and township roads or sporadic repair projects; large mixing plants have a capacity of more than 200 tons/hour, which can meet the needs of high-intensity construction such as highways. When choosing, it is necessary to combine the project schedule and the average daily usage for comprehensive calculation.
II. Investment and operating cost composition
Large equipment has a high degree of automation and complete environmental protection facilities, and the initial purchase cost is 40%-60% higher than that of small equipment. However, its unit energy consumption is reduced by 12%-15%, and the cost can be diluted through large-scale production in long-term operation.

III. Site planning requirements
The foundation of a small mixing plant covers an area of ??about 80-120 square meters, which is suitable for temporary mobile installation; a large station needs to reserve a fixed site of more than 500 square meters, and needs to be equipped with an aggregate yard and finished product silo. The nature of the land and environmental impact assessment requirements need to be evaluated when selecting a site.
4. Differences in core technology configuration
Small stations mostly use intermittent mixing hosts, equipped with simple burners and bag dust removal; large stations are equipped with continuous mixing systems as standard, with thermal regeneration functions and four-stage dust removal devices, and some models also integrate intelligent temperature control systems.
5. Maintenance and transportation considerations
The modular design of small equipment is convenient for transfer and transportation, but the durability of components is relatively low; large stations use heavy steel structures, and the maintenance cycle is extended by 30%, but professional teams are required for installation and commissioning.
From the above comparison, it can be seen that equipment selection requires a comprehensive assessment of factors such as construction scale, capital budget, and environmental protection standards, and there is no universal solution. It is recommended to entrust a professional organization to conduct a feasibility study before purchasing.
