Q: What is the normal speed in the transportation of the concrete mixer: In the case of idle speed (engine speed of 600 r/min) generally feed mixing every 4 r/min, when discharging at around 6 r/min, the gas engine speed from 1500 to 2000 r/min when the hydraulic pump and motor mechanical efficiency is highest, feed mixing around 10 r/min, when discharging 12 to 14 r/min. Speed is adjustable, through adjust the driving torque of each point, can make the speed increase or decrease, when the stirring speed too fast will affect the service life of the hydraulic system, general stirring speed in the process of transportation for the 3 revolutions per minute.

Q: Is it possible to mix the concrete in a mixing truck for eight hours?: When the concrete is removed from the mixture, it is best not to exceed 150min according to the temperature. But now with the development of the additive technology, and high performance concrete initial setting time and perhaps even control to 13-15 hours (Shanghai world financial center base raft concrete). You can discriminate in this way. Concrete stirred 8 hours, not casual water, workability change is not very big, can use, but 1 can back, part of discharge, stir some higher than the another two grades of concrete, quick stir for a few minutes and pouring into the part or not is not very important part of the bearing. According to the admixture, add admixtures, whisk for 3-4min, and reduce the use of one or two grades. If you have added a lot of water to the site, there has been a significant change in the ease of use.

Q: How many years does the concrete agitator truck go away?: Depending on how you use it, it doesn't matter if you take care of it for more than a decade

Q: The concrete mixer transporter is running continuously for no more than one hour: The concrete mixer transporter is running for no more than 8 hours. Concrete mixing is divided into two kinds: artificial mixing and mechanical stirring Manual stirring search When stirring, try to be quick, stirring time from adding water, should meet the following rules in general: The volume of the mixture is 4 ~ 5min (minute) under 30L. The volume of the mixture is 30L - 50L at 5-9min The volume of the mixture is 51L - 75L at 9 ~ 12min After mixing, it is required to do the slump measurement or the specimen forming according to the test requirement. The total operation must be completed in 30min from the beginning of the addition of water.Mechanical agitation First, it is the first batch, which is to make the ripper first, so as not to affect the mixing ratio of the mix. Start the mixer, blender, in turn, to join the gravel, sand and cement, stir evenly, add the water slowly again, all charging time not more than 2 min, water after all to join, to continue mixing 2 min.

Q: Is a tanker and a mixer a thing: Usually a concrete mixer is called a tanker But the tanker also has a concrete factory that transports the bulk cement, and USES the long can to drag the engine

Q: How did the concrete agitate the concrete: By rotating the concrete from the tank through a turbine fan, it can control the gears to adjust the speed of the material.

Q: How many cars do you have for a concrete tanker: See how much you pack 6 to 9 square and have more

Q: What is the purpose of the concrete mixer: It is the delivery of concrete!!! During the shipment, the tank continuously rotates and prevents concrete from solidifying. Once delivered, the concrete can be poured into the pump to get the concrete where it needs to be.

Q: Why is the concrete mixer turning on the road?: Because concrete is according to certain proportion with the mixture of the water cement ratio is one of the important factors, the size of water cement ratio directly determine the quality of concrete. In the process of concrete transportation, which is to keep the concrete maintain form without condensation, otherwise it will make concrete loss have building performance.

Q: What is the difference between a concrete mixer and a tanker?: A special truck used to transport construction concrete; Because of its appearance, it is also commonly referred to as the tian. These trucks are equipped with cylindrical agitating cylinders to carry mixed concrete. By the automobile chassis, mixing barrel, transmission system, water supply equipment, take full power and power, before and after the mixing drum support, deceleration machine, hydraulic transmission system, material in and out of the system, operating mechanism and other parts. Due to the technical bottleneck, the domestic mixer can be made from 3m to 8m cubic meters, and the four large parts of the volume are imported. Composition: type 2 chassis, drive system, hydraulic system, frame, mixing tank, feeding system, water supply system, operating system, ladder and so on. The top of the mixing tank is mounted on the rack, and the rear end is supported by two supporting wheels mounted behind the chassis.
