Domestic productionConcrete mixing equipmentThere are hundreds of manufacturers, a variety of varieties, has formed a certain scale of production, and emerged a number of well-known domestic brands, some technical performance has reached or close to the level of foreign brands。In addition, there are many agents to sell the products of foreign companies。In the face of so many products, how to choose according to their own situation?The following principles are recommended。

First, selection principle

(1) Production scale

Judging by the size of the production scaleConcrete mixingThe production capacity of the equipment。Annual output below 200,000m3，The productivity of concrete mixing equipment is generally not less than 90m3/h;The annual output is 200,000 and 300,000 m3，The productivity of concrete mixing equipment is generally 120m3/h;The annual output is more than 300,000 m3，The productivity of concrete mixing equipment is generally 150 m3/h or 200m3/h。

(2) Construction site

Depending on the size of the construction site, you can choose concrete mixing building orConcrete mixing plant。Selection of concrete mixing floor, aggregate one lift, the same capacityagitatorThe productivity is higher than that of the mixing station, the overall shape is neat and beautiful, the material yard covers a small area, the production environment is good, but the manufacturing and installation cycle is long, and the one-time investment cost is high。Selective mixingConcrete mixing plantThe 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) Equipment allocation

Select according to the equipmentConcrete mixerSpecifications and working dimensions。The loading capacity of the mixing truck should be matched with the discharge capacity of the mixer, and 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 plant。

(4) Management function

If intensive network management is used, the network management function of concrete mixing equipment should be considered to avoid difficulties in future upgrades。

(5) Equipment technical performance

Mainly from the advanced nature of the equipment, reliability, excellent health and versatility of several aspects of consideration。The equipment shall have the characteristics of advanced working principle, high degree of automation, powerful management function and good environmental performance。The equipment should be well configured, the control mode is reliable, the applicability is strong, and the maintenance performance is good。In addition, it is also necessary to consider high measurement accuracy, good mixing quality, high production efficiency, low energy consumption, large use of standard parts, and good interchangeability。

(6) Supplier reputation

It mainly includes whether the installation and debugging are strict;Whether technical guidance and training are in place;Whether the after-sales service is timely;The supply of spare parts is sufficient。

(7) Performance price ratio

Comprehensive pursuit of equipment technical performance is not wise, will increase unnecessary investment, but only the pursuit of low investment and reduce the technical performance of equipment will bring about an increase in the cost of use, such a practice is not advisable。The comprehensive performance of imported equipment in the domestic market is higher, but the price is also more expensive。Several well-known domestic brands of domestic equipment, although the comprehensive performance can not be compared with imported equipment, but the configuration of the key parts is also generally used imported components, the main performance is not much worse than imported equipment, the price is much lower。The more reasonable way is to choose the appropriate performance-price ratio。
