1. Production scale
Judge the production capacity of Medium concrete mixer according to the scale of production. The annual output is less than 200,000 m?, the concrete mixing equipment productivity is generally not less than 90m?/h; the annual output is 200,000 to 300,000 m?, the concrete mixing equipment productivity is generally 120m?/h; the annual output is more than 300,000 m? The productivity of concrete mixing equipment is generally 150m?/h or 200m?/h.
2. Construction site
According to the size of the construction site, concrete mixing tower or Medium concrete mixer can be selected. The concrete mixing plant is used to increase the aggregates at a time. The productivity of the mixer with the same capacity is higher than that of the mixing plant. The overall shape is neat and beautiful, the material yard occupies a small area, and the production environment is good. However, the manufacturing and installation cycle is long and the one-time investment cost is high. When selecting a concrete mixing plant, the aggregate needs to be lifted twice, the layout is flexible, the manufacturing and installation cycle is short, and the one-time investment cost is low, but the material yard covers a large area and the production environment is poor.
3. Equipped with equipment
Select the specifications and working dimensions of the concrete mixer according to the equipment attached. The loading capacity of the mixer truck should be matched with the discharge capacity of the mixer. Improper matching will affect the work efficiency. The loading capacity of the loader should match the loading height of the batching station of the concrete mixing station.
4. Management function
If intensive network management is adopted, the network management functions of concrete mixing equipment should be considered to avoid difficulties in future upgrades.
5. Equipment technical performance
It is mainly considered from several aspects of equipment advancement, reliability, superiority and versatility. The equipment should have the characteristics of advanced working principle, high degree of automation, powerful management function and good environmental performance. The equipment should be equipped with good configuration, reliable control method, strong applicability and good maintainability. In addition, high measurement accuracy, good mixing quality, high production efficiency, low energy consumption, large usage of standard parts, and good interchangeability should also be considered.
6. Supplier reputation
It mainly includes whether the installation and debugging are strict; whether the technical guidance and training are in place; whether the after-sales service is timely; whether the supply of spare parts is sufficient, Qingdao New Construction Machinery Co., Ltd. high-quality manufacturers are worthy of favor.
7. Performance-price ratio
It is unwise to pursue equipment technical performance in an all-round way and will increase unnecessary investment. However, only pursuing low investment and reducing equipment technical performance will increase the cost of use. This approach is also undesirable. The comprehensive performance of imported equipment in the domestic market is higher, but the price is also more expensive. Although the comprehensive performance of several domestic well-known brands of domestic equipment cannot be compared with imported equipment, the configuration of key parts also generally uses imported components. The Medium concrete mixer main performance is not much worse than that of imported equipment, but the price is much lower. A more reasonable approach is to choose an appropriate price-performance ratio.
