The use of concrete mixers must strictly abide by the "Construction machinery Safety Technical Regulations",Single horizontal shaft mixer用途Before use must carefully check the power equipment, working mechanism and supporting the use of lifting, transportation pouring equipment。Starting and feeding of concrete mixer: the mixer must be started without load and fed during operation, otherwise the machine will be damaged due to excessive starting torque。When the mixer mixes concrete, it is necessary to calculate the feed amount according to the specified batching ratio and water-cement ratio, the humidity of the coarse and fine aggregate should be determined in advance, and the theoretical mix ratio is converted into the construction mix ratio, and then the quality of each component material needs to be added each time according to the construction match ratio and the discharge capacity of the mixer。The calculated value of the feeding should be tested and strictly implemented once determined.优质Single horizontal shaft mixer用途The particle size of the maximum aggregate should meet the specified requirements, and the requirements of the forced mixer for the maximum aggregate particle size are more stringent, otherwise it will produce card material。If the added material changes or the humidity changes due to rain, snow and other reasons, it should be re-determined, recalculated and determined the feeding amount。Important concrete structures, cost ratios and water-cement ratios should be inspected every 4 hours。

绵阳优质Single horizontal shaft mixerConcrete 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Single horizontal shaft mixerConcrete 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 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。Single horizontal shaft mixer用途After 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Single horizontal shaft mixer用途Pay 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。

Select mixing plant site need to pay attention to what points？1.Construction of mixing plant should choose a flat, wide, away from residential areas。If the hillside terrain can be fully utilized and the material field is set on the higher ground plane of the hillside, the loading height of the batching machine can be reduced, so that the climbing Angle on the loader is small or no climbing.优质Single horizontal shaft mixer用途It saves energy and reduces wear。2 Convenient transportation (for tank trucks, pump trucks, cement trucks, etc.) 3.It should be built next to the material yard. The distance between the material yard and the sand plant should be close to ensure that the water supply is sufficient。According to the existing natural landform of the mixing station site, the production area and living area of the mixing station can be divided into two independent areas, the size of the available site in the living area is 36M×70M, and the production area of the mixing station is a rectangle.优质Single horizontal shaft mixer用途The site is basically flat and in place。But to consider the ground drainage, so that there is no water phenomenon。
