1) The ground screw bolt of the cement silo is poured into the reserved pit of the foundation. When the center line of the cement silo support is adjusted to coincide with the center line of the foundation, the above four flanges are adjusted on the same level (measuring method: theodolite or transparent plastic hose with diameter of 8-10 and color water measurement method), the concrete can be selected for casting。The grade of the concrete used in the reserved pit should be one level higher than the concrete used in the foundation, and in the winter construction, in order to shorten the construction period, the concrete used should be added with early strength antifreeze。Wait for the foundation concrete to set 5-7 days before installing the cement silo body. When installing the cement silo body, it is necessary to measure the verticality of the cement silo body with a theodolite. The verticality is one thousandth of the height。In order to shorten the construction period, embedded parts can also be used in infrastructure instead of anchor bolts to fix cement silos or mixers。(2) Installation of the mixing machine: the bottom plane of the mixer chassis is properly padded,Attach the legs to the main engine with hinges,Install the cement scale,水秤,After weighing the admixture,Ready to lift,Measure and adjust engine chassis,Make it horizontal,After the center line of each leg coincides with the center line of the foundation, the anchor bolt can be poured into the reserved pit (or welded between the base and the reserved embedded part)..(3) Installation of other parts: after the installation of the main engine and cement silo,Screw conveyor can be installed,Before hoisting,Check the filling of oil and grease at each lubrication point,An empty car running test is to be conducted,Find problems and solve them in time,Part of the dosing machine installation,Position as required by the foundation drawing,The small dosing machine can be placed on the solid foundation pier plane,Large batching machine requires pouring anchor bolts,After the installation of each mechanical part,Check that all lubrication points of various equipment are filled with lubricating oil (the lubricating oil suitable for low temperature conditions must be replaced in winter in Northeast China) or grease,Wiring and empty car running test can be performed according to the requirements of the manual and electrical schematic diagram.It can accurately and conveniently input, adjust and modify the set value and formula number of each material, and multiple common concrete ratios can be stored inside the microcomputer。2. 优质Concrete mixing plantThe control system has perfect self-locking and interlocking functions to ensure the accurate and reliable operation of the system, and has common fault detection and alarm functions。3. The whole mixing plant is equipped with a good lighting system, and the main control room, mixing area and material area are equipped with lighting。4. The concrete mixing plant uses microcomputer to control the timing requirements of the process, and realizes automatic control of the production process from measurement to feeding, mixing to discharging. The management of the entire production site of the mixing plant is completed by two operators and two auxiliary personnel。5.The weighing system of concrete mixing station is equipped with zero output.Concrete mixing plantproducerCan automatically remove the tare weight, correct the drop, for the single weight single material weighing with a button and fill function, more effectively control the measurement accuracy, with a light alarm device。
Concrete mixing stations are becoming more and more common, and more and more people are using concrete mixers。However, many people do not know how to clean a concrete mixer。First, before using the concrete mixer, check that the controller is in good condition。Concrete mixing plantproducerAfter shutdown, pour the water and stones into the mixing bucket for 10 to 15 minutes for cleaning, and then remove the water and stones。When the operator needs to enter the mixing cylinder for cleaning, in addition to cutting off the power, remove the fuse, but also need to lock the switch box。Secondly, the concrete mixer should be regularly maintained, such as cleaning, lubrication, refueling and so on。Third, we must remember that the accumulation of concrete in the concrete mixing drum cannot be removed by hammering。We had to chisel it out。Fourth, winter use优质Concrete mixing plantproducerPay attention to cleaning the drum of the concrete mixer with water after the end of the work, and drain the water in the pump, water tank and water pipe to avoid frostbite of the pump, water tank and water pipe。

1.Performance label of construction concrete;优质Concrete mixing plantFrom this to choose what kind of mixing machine。Such as water conservancy projects must choose a forced mixing host。In addition, the batching station and storage bin should be selected according to the types of concrete materials that can be mixed。2.The task quantity and duration of concrete construction;Use these two parameters to choose how big the mixing plant is。The total task quantity of concrete is set as M;The number of days for concrete pouring is T;The working hours per day are H;If the utilization factor is K, the specification of the mixing plant X=M/(T*H*K) should be selected, where K is 0.7-0.9。The transportation condition of finished concrete should also be considered in the selection。Such as: direct pumping or vehicle delivery。The volume of the conveying vehicle is also an important basis for determining the type of mixing station。3.Construction environment and construction object;When choosing to purchase a concrete mixing plant, the impact of the construction object and the construction environment should be fully considered, so as to ensure the smooth construction and construction quality。In the following cases, we recommend that you be prepared。4.When the site needs to pour a large amount of one-time, high quality requirements, and there is no nearby reinforcement of the mixing plant, choose two smaller specifications of the mixing plant, or choose a master a pair of dual machine preparation。5.When the site traffic is inconvenient and maintenance personnel need to spend a lot of time entering and leaving the site, choose to use the same smaller specifications of the dual machine station, or prepare enough spare parts, so as to ensure the smooth construction progress。6.When the construction site is more dispersed, but the distance between the sites is not too far, the transport radius of the concrete mixing truck is not more than half an hour by car, and the transport of the dump truck is not more than 10 minutes by car。The use of multi-number centralized mixing to improve the utilization rate of mixing plant and construction economic benefits。7.The quality of operators;Generally speaking, the structure of the small mixing plant is simple, and the control system is also simple, so the requirements for operation and maintenance personnel are low。The larger station structure is complex and the degree of automation is high, so the requirements for operators are also high。Therefore, in addition to the previous factors, you should also consider this factor when purchasing a mixing plant。8.Preparation selection;Under normal circumstances, the manufacturer has a mature product preparation, such as specifications, quantities, varieties, etc。You can make your special request when ordering the product。We will do our best to meet your requirements。However, in the purchase of products should not be greedy, which will cause economic waste。In addition to referring to the prices of different manufacturers when purchasing products, special attention should be paid to the preparation lists of different manufacturers。Concrete mixing plantproducerIn addition to the above specifications, varieties and quantities, the most important thing is the manufacturer of the parts。In summary, you can always choose the most suitable model for you。In the choice of models do not pursue the good, but should pursue the most suitable and meet your needs, because such a choice is the most economic and most effective。
