There are many details about the purchase of concrete mixing plant that we need to grasp. Today we will introduce the following:
1. Performance number of concrete construction. : with mixer
Mixing machine is the core part of mixing plant. According to the performance label of concrete, what kind of mixing machine should be selected. If the water conservancy project must choose the double horizontal shaft forced concrete mixer. In addition, the selection of concrete batching machine and cement bin shall be determined according to the type of concrete mixing materials.
2. Concrete quantity and construction period: select mixing plant model
These two parameters are used to select the size of the concrete mixing plant. Make the total task amount of concrete a; the pouring days of concrete B; the working hours per day C; if the utilization coefficient is x, the mixing plant specification x = A / (b * c * x), where x is 0.7-0.9. Transportation conditions of finished concrete shall be considered in selection. Is it a direct pump or a vehicle? The volume of the conveying device is also an important basis for determining the type of mixing device.
3. Construction quantity and construction cycle: determine one station or two battles
When the quantity of concrete to be poured at one time is large and the quality requirements are high, and there is no concrete mixing station nearby for reinforcement, it is better to choose two sets of smaller mixing stations, or choose one set of mother mix and one pair of double machine mix.
4. Traffic conditions
When the site traffic is not convenient, the maintenance personnel of the mixing station need to spend a lot of time in and out of the site. It is better to choose the same small size of two stations or prepare enough spare parts to ensure the smooth progress of the construction.
5. Transportation distance
When the construction site is scattered, but the distance between the construction sites is not too far. The transportation radius of Sichuan concrete mixing plant is not more than 30 minutes for automobiles, and that of dump trucks is not more than 10 minutes for automobiles. It is better to adopt multi station centralized mixing to improve the utilization rate of mixing station and construction economic benefits. Sichuan concrete mixing station
6. Operator quality: large station or small station
Generally speaking, the components of small-scale concrete mixing plant are simple in structure and control system, so the requirements for operation and maintenance personnel are low. The large-scale concrete mixing plant has complex structure and high degree of automation, so the requirements for operators are also high. Therefore, when purchasing the concrete mixing plant, in addition to the first few factors, operators should also be considered.
7. Configuration selection: no special requirements
Generally, the manufacturer has mature equipment configuration, such as specification, quantity, variety, etc. You can also make special requests when ordering the mixing equipment, and we will try our best to meet your requirements. However, when purchasing products, we must not be greedy and complete, which will cause unnecessary economic waste. In addition to the purchase of concrete mixing plant equipment, in addition to referring to the prices of different manufacturers, special attention should be paid to the configuration list of different manufacturers. In addition to the above specifications, varieties and quantities, the most important is the manufacturer of accessories.
