Many aspects of the construction of concrete mixing plant need to pay attention to. As the saying goes: you have to plan first to do things, so for customers who invest in concrete production, the preparation of concrete mixing plant is the focus! So what do we need to pay attention to in the preparation of concrete mixing plant? The following NFLG to tell you.
Determination of the size of concrete mixing plant
Before determining the scale of investment, it is logical to do a good job of market research. If it is used within the Ministry of Construction, the production capacity of the concrete mixing plant to be purchased should be decided according to the construction capacity and the amount of commercial concrete. For example, for highway or small-scale (1-year duration) projects, a mixing plant with a capacity of 1 to 1.5 square meters is generally used. For commercial concrete mixing plant, the size of the plant should be decided according to the economic development of the region, the demand for commercial concrete and the investment capacity of the market in the region, and the capacity of the plant should be 1.5 square meters or more.
The choice of concrete mixing plant site
When choosing the site, the site should be close to the stone quarry and sand plant, with sufficient water supply, and far from residential areas. If you can make full use of the hillside terrain and set the site on the higher ground level of the hillside, you can reduce the loading height of the batching machine and make the loader climbing angle of loading small or no climbing, which not only saves energy but also reduces wear and tear. When installing the equipment foundation, pay attention to avoid above-ground and underground fiber optic cables, power supply or communication cables.
To determine a reasonable concrete mixing plant equipment configuration
1. The choice of aggregate supply method: using loader to supply materials. If the concrete mixing plant is used for highway construction (short duration, frequent moving and relocation), it is necessary to choose the mixing plant with quick-loading and modular structure.
2. The choice of aggregate conveying belt machine: If the site is wide, a small inclination angle (18°) flat belt conveyor should be preferred (in order to reduce the equipment procurement cost, the lifting hopper method can also be chosen); if the site area is restricted, a large inclination angle (generally 40°~50°) baffle belt machine (with additional belt structure, it can reach 90°) can be considered. However, in the wet environment of sand and gravel, the large inclination baffle belt machine has the disadvantage of sticky sand, and when the belt returns, the phenomenon of sand falling below the belt is more serious, and the ratio of commercial concrete should consider the utilization factor of sand.
3. aggregate batching machine (scale) selection: a complete commercial concrete mixing plant aggregate scale for the cumulative measurement of 1 scale, separate measurement for 2 to 4 scales. In order to make each aggregate has more storage capacity, each aggregate can be designed and made into 2 scales batching; if the construction requirements are low, choose 2 kinds of aggregate cumulative measurement of the batching machine; if the project has requirements, choose 3 or 4 kinds of aggregate scale cumulative measurement of the batching machine, or even each aggregate separately measured batching machine; other scales can be selected according to the demand to determine the configuration of cement scale, fly ash scale, powder admixture scale ( by the child spiral machine feed), water scales and liquid admixture scales (1 to 2), etc.
4. testing instruments: such as with the sand water content detector, through the microcomputer control, according to the different moisture content of sand, can realize the automatic adjustment of online water addition. The application of slump detector can observe the homogeneity of commercial concrete. Customers can choose a reasonable configuration according to their needs and make provisions in the contract.
Inspection of concrete mixing plant manufacturers
Customers should examine the general situation (production scale, production capacity, product quality level and service quality, etc.) of several better concrete mixing plant manufacturers. From the production process, production process, examine the manufacturer’s ability to quality system. The prototype has been put into use for on-site inspection, listen to the views of the use of units, to understand the actual quality level of the equipment, the selection of supporting parts, etc. When inspecting and talking about the contract, pay attention to direct communication with the manufacturer’s designers, large and demanding mixing plants, so that the designers can directly and clearly understand the customer’s requirements and working conditions, so as to develop a proper design plan, so as not to cause losses to the customer.
Our factory has been serving customers in the construction industry for many years, over these years, whether it is experience in building plants, equipment manufacturing experience, equipment maintenance experience, installation experience, problem handling experience has been more mature, you want to invest in the concrete mixing plant industry, then come to NFLG, we can follow the whole process, to help you build a set of reasonable concrete mixing plant.
