1、 Determination of mixer grade

投資方應充分了解國內(nèi)外施工廠家的同行業(yè)產(chǎn)品質(zhì)量水平，服務能力和價格信息，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 capacity and price information of domestic and foreign construction manufacturers in the same industry, market research, on-site inspection, manufacturer processing and quality assurance ability. 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，應確保場地離石料場和砂廠較近，以保證有足夠的水分，并遠離住宅區(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 and make the loader feed and climbing angle small or no need to climb, which can 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.

四，傳送帶機選

4、 Conveyor belt selection

如場地寬闊，應優(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

If the site is wide, priority should be given to the development and selection of a small inclination angle of 18 °, flat belt conveyor conveying 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 machine has the disadvantage of sticking sand. When the belt returns, the phenomenon of sand falling under the belt is analyzed and compared
