1, concrete mixing plant construction site should have flood control, drainage systems and measures, the road should be kept unblocked。2, the foundation pit, the trough should have a system of drainage ditches, and should often check the stability of the soil wall of the mixing station to avoid the collapse of the soil。3. After brushing the template with spacer, it should be covered to prevent it from being washed by rain;If it is found that the spacer is washed by rain, it should be repainted and the concrete should be poured。4, cement shed and mixer shed should be checked frequently to prevent rain leakage。5, the water content of sand and stone should be often determined, and should be deducted from the water added in the mix ratio。6, mixing station rainy day transportation of raw materials and concrete, should be covered。7. Before pouring concrete, the water in the mold should be drained。8. If the open-air structure and components of the mixing station require continuous construction without construction joints, the awning should generally be set up。Otherwise, adequate cover and waterproof materials (such as tarpaulins, linoleum, etc.) should be prepared to cover in time to prevent rain erosion。优质Cylinder batcher用途If the surface of the component is washed by rain, it should be smoothed again。9. Slope and bridleway should take anti-skid measures。10, mixing station electric machinery and wires, should be often checked by electricians whether leakage;优质Cylinder batcher用途When leakage is found, the work should be stopped immediately for repair。

Concrete mixing is an operation method of mixing cement, lime, water and other materials evenly。Concrete mixing is divided into two types: manual mixing and mechanical mixing of water。优质Cylinder batcher用途Concrete mixing plant is widely used in China's industry, agriculture, transportation, national defense, water conservancy, municipal and other construction projects, the demand is increasing。Cement concrete mixing plant is widely used in China's industry, agriculture, transportation, national defense, water conservancy, municipal and other construction projects, the demand is increasing。Although the domestic concrete mixing equipment continues to innovate and progress on the basis of learning from foreign products, the technical level is gradually improved, but as far as the whole mixing station is concerned, the research on the batching process is still insufficient, especially for the new concrete mixing station, often rely on the experience accumulated by supporting manufacturers for many years.广安优质Cylinder batcherIt basically meets the quality requirements of the national standard for concrete mixing station, and there is no special experimental research on its conveying technology and feeding technology。

There are two common types of concrete batching machines on the market: belt batching and cylinder batching PLD series concrete batching machines are composed of three parts: feeding system, weighing system and electrical control system。Feeding system: composed of storage hopper and feeding device, etc., the main function is to store materials and feed to the weighing hopper under the control of the control system。PLD800-1200 type, feed for belt conveyor;Weighing system is the key part of batching machine, which is composed of weighing hopper, suspension device, weighing system sensor, batching controller, etc。But there is no difference in the weighing system of various batching machines;The electrical control system is the core part of the batching machine, and its function is to realize the weighing, display, operation and complete various automatic batching programs of the whole batching machine。优质Cylinder batcherThe system is mainly composed of a batching controller and a strong current loop quantity part.Different types of batching machines are different，PLD800 2/3 kinds ,PLD1200 2/3/4 types, PLD1600 2/3/4 types ,PLD2400 3/4 kinds ,PLD3200 3/4 kinds ,PLD4800 3/4 kinds ,Depending on the type，Select the model;Proportioning bucket capacity is also different，PLD800 0.8m3,PLD1200 1.2m3,PLD1600 1.6m3,PLD2400 m3,PLD3200 3.2m3 ,PLD4800 4.8m3。Users can choose their own dosing machine through these key issues, I believe that these must be able to give you help in the selection of dosing machine。In the use of concrete mixing station，The concrete batching machine plays a very important role，It is a sand and gravel batching device using a loader or a belt conveyor，Cement silo，Various types of mixers and other metering devices are used together,Combine into automatic and semi-automatic mixing stations，The electronic weighing system can effectively ensure the accuracy of the mix ratio of cement, sand and stone。The top panel of the batching machine can be reduced or removed as needed, which can greatly reduce the labor intensity of the feeding part and increase the convenience of construction. Our company's exquisite technology greatly improves the quality of the concrete mix ratio of PLD800-4800 concrete batching machine, which is the ideal batching device for various types of mixers。优质Cylinder batcher用途Sounds easy, but how to choose the concrete batching machine, choose the right batching machine is also a knowledge, because it is not only related to the efficiency of the mixing station, but also related to the quality of work。

广安优质Cylinder batcherConcrete is actually "concrete."。Concrete, referred to as "concrete (tong)" : refers to the aggregate cemented into a whole by the cementing material engineering composite material collectively。Generally speaking, the term concrete refers to the use of cement as a cementing material, sand, stone as aggregate;With water (with or without admixtures and admixtures) according to a certain proportion, by mixing, forming, curing and cement concrete, also known as ordinary concrete, it is widely used in civil engineering。It is made of cementing material, aggregate and water according to a certain proportion of preparation, by stirring vibration molding, under certain conditions of maintenance of artificial stone。优质Cylinder batcherConcrete is rich in raw materials，Low price，The production process is simple，So the use of more and more;At the same time, concrete also has high compressive strength，Good durability，Wide range of strength grades，Make it a very wide range of use，Not only used in various civil engineering，The shipbuilding industry，Machinery industry，Ocean exploitation，Geothermal engineering，Concrete is also an important material。The concrete pump is composed of a pump body and a conveying pipe。It is a kind of machine that uses pressure to transport concrete continuously along the pipeline, mainly used in house construction, bridge and tunnel construction。At present, it is mainly divided into gate valve concrete conveying pump and S-valve concrete conveying pump。The other is to install the pump body on the chassis of the car, and then equipped with a telescopic or flexed fabric rod, and composed of a pump truck。

Concrete mixing station is mainly composed of material storage system,Cylinder batcher用途Material weighing system, material conveying system, mixing system, powder storage system, powder conveying system, powder metering system, water and admixture metering system and control system and other ancillary facilities。Mixing machine Mixing machine according to its mixing mode is divided into forced mixing and self-falling mixing。Forced mixer is the mainstream used in mixing stations at home and abroad.优质Cylinder batcherIt can mix a variety of concrete such as fluid, semi-dry hard and dry hard。The self-falling mixing machine mainly mixes liquid concrete, which is rarely used in mixing stations。The forced mixer is divided into spindle planetary mixer, single horizontal shaft mixer and double horizontal shaft mixer according to the structural form。Among them, the double horizontal shaft forced mixer has good comprehensive performance。Weighing system Material weighing system is a key component that affects the quality of concrete and the cost of concrete production, which is mainly divided into three parts: aggregate weighing, powder weighing and liquid weighing。Under normal circumstances, the mixing station below 20 cubic meters per hour adopts the superposition weighing method, that is, the aggregate (sand, stone) is weighed with a scale, the cement and fly ash are weighed with a scale, the water and the liquid admixture are respectively weighed, and then the liquid admixture is put into the water weighing bucket before mixing。In the mixing station of more than 50 cubic meters per hour, the method of independent weighing of each material is used, and all weighing is controlled by electronic scales and computers。The weighing accuracy of aggregate is ±2%, the weighing accuracy of cement, powder, water and admixture is ±1%。

How do we distinguish the quality of concrete mixing station？The quality of cement is directly related to the quality and durability of the building, and is also the key link in the quality control of the mixing station!However, the current order of the cement industry is not good: unqualified clinker in cement clinker is widespread, the content is far below the standard value is normal, small cement can not be called cement, can only be called powder。Cement supervision is seriously missing!Testing strength, setting time and stability are far from enough。1、优质Cylinder batcher用途Clinker: standard requirements, calcium silicate mineral is not less than 66%, calcium oxide and silicon oxide mass ratio is not less than 2。But are our cement factories often up to standard？Strength tests are usually performed only。2, cement clinker content: standard requirements, ordinary Portland cement clinker, gypsum content should be greater than or equal to 80%, less than 95%。But now, even if the large cement clinker content is generally only 65% to 70%, let alone the small cement plant near it in Beijing (in fact, can only be called the grinding station, do not know how to make a cement plant name), the general knowledge of small cement clinker is only about 50%。Small cement cannot be called cement。At best, it's a mixture!3.广安优质Cylinder batcherTest method: Cement supervision by Technical supervision Bureau，Random inspection once a year，Can't restrain the production of cement plant!The inspection items of the national inspection standards only have strength, setting time and stability，Some chemical indicators are far from adequate!These indicators are easily met with small cement!We should strictly test the clinker，Clinker content testing should be increased when accepting cement，Not only strength, setting time and stability should be tested，当然，Magnesium oxide, trisulfur oxide and other chemical indicators can not be less!
