(1) The selection of admixtures There are many admixtures with different effects, especially for different types of cement。优质Cylinder batcher用途In the selection of admixtures, should be based on the needs of the project, the site of the material conditions, with reference to the relevant information, through the test to determine。(2) Determination of admixtures The admixtures of concrete have appropriate admixtures, and the admixtures are too small, often unable to achieve the expected effect;If the amount is too large, it will cause waste, sometimes affect the quality of concrete, and even cause quality accidents。Therefore, the optimal dosage should be determined by test。(3) Adding methods of admixtures Different methods of adding admixtures into concrete mixes, the effect is different。For example, the effect of post-blending method is better than that of pre-blending method and co-blending method, and its dosage is only half of that of pre-blending method and co-blending method。The so-called first blending method is to mix the water-reducing agent with cement first and then mix with aggregate and water;The co-blending method is to dissolve the water-reducing agent in water to form a solution and then add it to the mixture to stir together.Post-mixing method means that after the concrete mix is sent to the pouring site, water reducing agent is added and then evenly mixed again for pouring。 因此，Cylinder batcher用途The use of admixtures should be determined by tests according to engineering characteristics, material conditions and construction conditions。

Concrete mixing station is widely used in infrastructure construction, many users of the understanding of concrete mixing station is only limited to how to use, for the quality of concrete mixing station is good or bad, and not very understanding, let alone to check the quality of the station bought。The main components of the concrete mixing station are also a few, so as long as these major components do not have quality problems, then the concrete mixing station does not have too much quality problems。1.If the mixer is a self-falling mixing drum, the radial runout of the discharge ring does not exceed 1% of the diameter of the feed port, but also check the quality of the steel bar of the vibrating screen mesh on the mixer and the reasonable size of the screen and screen hole and check the installation accuracy of the screen;2.The operation of the transmission system should be flexible, without abnormal sound;3.优质Cylinder batcher用途Belt conveyor, bucket elevator and cantilever shovel transmission should be smooth, the operation should be flexible, the brake can be high, no abnormal noise, no card chain;4.The inspection of the measurement system is also very important, to check the sensitivity and accuracy of the measurement system;5.Reduce the lifting temperature of the machine should also pay attention to reach the temperature of the qualified book;6.Metering hopper in and out of the material should be smooth, no accumulation, overflow and other phenomena;7.优质Cylinder batcher用途Safety valve can not appear leakage phenomenon;8.The quality of cement tank is qualified;9.The matching line installation should be reasonable and the installation of equipment should be correct。

1, mixing system Mixing system by motor, reducer, a pair of open gear and chain drive, mixing device and mixing tank composition。The motor is mounted on the end face of the reducer, and drives the two horizontally configured mixing shafts to reverse equal speed rotation respectively through a pair of open gears and chain drives。The mixing shaft is supported in the groove mixing tank formed by welding steel plate。Each stirring shaft is equipped with six stirring blades, and the mixture in the stirring tank is driven by the stirring blades to make "mutual cutting and turning" operation and alternately move according to the spiral trajectory。The combination of horizontal eddy current and vertical reverse flow agitation makes the material get rapid and strong agitation。优质Cylinder batcher用途Due to the small linear speed of the perimeter of the mixing blade, the energy consumption of the mixing concrete, the wear of the blade and the lining plate are much smaller than other mixers。The shape, quantity and arrangement of stirring blades are the main factors affecting the mixing quality and technical performance of the mixer。A special floating sealing device is provided for the connection of the mixing shaft and the two ends of the mixing tank。The sealing device is also equipped with a special oil feeder, the main mixing shaft rotates, and the oil feeder automatically supplies oil to each sealing part to ensure the lubrication of the mixing shaft shaft end seal and support。2. Feeding system Feeding system is composed of hoist, feeding rack, hopper, etc。When loading，Load the mixture to be stirred into the hopper，The starting winch motor drives the drum to rotate through the reducer，When the hoisting wire rope pulls the hopper up to a certain height along the loading rack track，A pair of rollers on the bottom of the hopper enter the feeder level fork，The door opens automatically，Feed the material into the mixing tank。3. The discharge device is equipped with a discharge door at two arcs on one side of the cylinder, which can be rotated around the horizontal axis to open and close the eyes through an electric push rod。The horizontal shafting at both ends is supported on a support seat fixed to the bottom of the mixing tank。The length of the discharge door is slightly shorter than that of the tank. When the discharge door is opened, most of the mix is discharged by its own weight, and the residual mix is forced out by the mixing blade, so that the discharge is clean and fast without segregation。The joints of the discharge door and the mixing tank are sealed with wear-resistant rubber strips, and the backing plate on the support seat can be adjusted to ensure the sealing after wear。4、 Cylinder batcher用途Water supply system The water supply system is made of unipolar centrifugal pump and quantitative principle。Under the guise of adjusting the pointer on the water tank dial, different amounts of water can be supplied。The two spray pipes are located directly above the two mixing shafts。The inlet and outlet of the water tank is controlled by the joystick of the three-way valve。When the water tank is supplied, the three-way valve cuts off the water discharge pipe, and the water inlet pipe is closed when the water tank is discharged。5, rack The rack is composed of bottom frame, legs, railings, platform, ladder, etc。Except for the railing, the rest are connected by bolts to the rack, and the railing is inserted into the socket hole on the rack。6. Electrical system。

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。Cylinder batcher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Cylinder batcher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。
