    概述:一、攪拌車檔次的確定1、 Determination of mixer grade投資方應充分了解國內外施工廠家的同行業產品質量水平,服務能力和價格信息,市
    1、 Determination of mixer grade
    The investor shall fully understand the product quality level, service capability and price information of domestic and foreign construction manufacturers in the same industry, market research, on-site investigation, manufacturer processing and quality assurance capability. Manufacturers of complete sets of equipment and products with high quality and low price can be selected by holding defense meeting, bidding meeting, etc. Determine the scale and grade of commercial concrete mixer according to the capital ownership.
    2、 Selection of mixer site
    When selecting the mixing site, it shall be ensured that the site is close to the quarry and sand factory to ensure sufficient moisture and away from the residential area. If we can make full use of the hillside terrain and set the material yard on the hillside and high ground, we can reduce the batching height of the batching machine, make the loader feed and climbing angle small or do not need to climb, so as to save energy and reduce wear. The installation of equipment base shall avoid aboveground and underground optical cables, power supply or communication cables.
    3、 For the selection of aggregate supply mode, it is recommended to use loader for feeding.
    If the mixer is used for expressway construction (short construction period and frequent relocation problems), the mixer with fast loading and modular structure shall be selected.
    Fourth, conveyor belt selection
    If the site is wide, priority should be given to the development and selection of low inclination angle 18 °, flat belt conveyor transportation lifestyle (in order to reduce the procurement management cost of enterprise equipment companies, the effective lifting hopper can also be selected). If the site area is not continuously limited to a certain extent, the edge retaining belt machine with large inclination angle (generally 40 ° ~ 50 °) can be fully considered (some additional belt structures can reach 90 ° at the same time). However, in the wet environment of sand and gravel, the large angle edge retaining belt conveyor has the disadvantage of sticking sand. When the belt returns, the analysis of sand falling under the belt is more serious. The utilization correlation coefficient of sand should be considered to improve the proportion of commercial concrete.
    Let's look at the choice of aggregate mixing
    The aggregate scale of a complete, commercial concrete mixer is the cumulative measurement of scale 1 and the individual measurement of scale 2-4. In order to ensure that each aggregate has sufficient storage capacity, each aggregate can be designed into 2 weighing ingredients.
    If the enterprise's construction technical requirements are relatively low, two batching machines measuring the aggregate cumulative value shall be selected; If a project has special requirements, the batching machine for cumulative measurement must be selected by selecting 3 or 4 aggregate scales, or even the batching machine for each aggregate can be used separately.
