1、 Determination of mixer grade

投資方應(yīng)充分了解國內(nèi)外施工廠家的同行業(yè)產(chǎn)品質(zhì)量水平，服務(wù)能力和信息，市場調(diào)研，現(xiàn)場考察廠家加工，質(zhì)量保證能力?？赏ㄟ^召開答辯會，招標(biāo)會等方式，選擇所需成套設(shè)備的生產(chǎn)廠家，選擇質(zhì)優(yōu)價廉的產(chǎn)品。根據(jù)資金歸屬，確定商品混凝土攪拌機的規(guī)模和等級。

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.

二、攪拌車場地的選擇

2、 Selection of mixer site

選擇攪拌場地時，應(yīng)確保場地離石料場和砂廠較近，以保證有足夠的水分，并遠(yuǎn)離住宅區(qū)。如果我們能充分利用山坡地形，將物料場設(shè)置在山坡、較高的地面上，可以降低配料機的配料高度，使裝載機進(jìn)料、爬坡角度小或不需要爬坡，既節(jié)省能源又減少磨損。設(shè)備基地的安裝應(yīng)注意避開地上、地下光纜、電源或通信電纜。

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.

三，骨料供應(yīng)方式的選擇建議采用裝載機供料。

3、 For the selection of aggregate supply mode, it is recommended to use loader for feeding.

攪拌車的選用如用于高速公路工程施工(工期短、移動進(jìn)行搬遷問題頻繁)，則要通過選用快裝式、模塊式結(jié)構(gòu)的攪拌車。

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.

第四，傳送帶機選

Fourth, conveyor belt selection

如場地寬闊，應(yīng)優(yōu)先發(fā)展選用小傾角18°，平皮帶機輸送生活方式(為降低企業(yè)設(shè)備公司采購管理成本，也可以通過選用有效提升料斗方式)。如果沒有場地面積不斷受到一定限制，可以充分考慮大傾角(一般為40°～50°)擋邊皮帶機(采用一些附加皮帶結(jié)構(gòu)，可以同時達(dá)到90°)。但在砂石潮濕的環(huán)境下，大傾角擋邊皮帶機有粘砂的缺點，皮帶返程時，皮帶下面落砂現(xiàn)象分析比較具有嚴(yán)重，商品提高混凝土配比要考慮砂的利用相關(guān)系數(shù)。

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.

我們來看看集料混合的選擇

Let's look at the choice of aggregate mixing

一個完整的，商業(yè)混凝土攪拌機集料規(guī)模是1規(guī)模的累計計量和2-4規(guī)模的個人計量。為了保證每個骨料有足夠的貯存容量，可將每個骨料設(shè)計成2個稱重配料。

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.

如果企業(yè)施工技術(shù)要求相對較低時，選用2種骨料累計價值計量的配料機;如果一個工程有特殊的要求，則必須通過選用3種或4種骨料秤累計計量的配料機，甚是每種骨料可以單獨使用計量的配料機。

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.
