Industrial Agitator Improve The Strength And Durability Of Concrete
Aug 04, 2017

Industrial Agitator is a complete set of special equipment for continuous mixing of pavement base materials. It is suitable for grassroots construction of ordinary highways, highways, highways, urban roads, sports fields and airports. At present, the cement content of the cement stabilized soil base mixture is generally about 5%, while the mixing of the mixture in the mixer for about 10s, it is difficult to make the mixture, especially the cement to be fully stirred. In order to ensure the use of strength, the actual production of cement content generally take the upper limit, which led to grass-roots pavement prone to cracks; but if the cement content to take a small value, will be due to uneven mixing lead to low strength of the mixture, local subsidence phenomenon.

Vibration stirring is one of the effective methods to strengthen the mixing process. As early as the 20th century, 30 years, foreign scholars will vibration and stirring technology used in cement concrete mixing test. Subsequently, the domestic scholars also launched a vibration mixing technology related research. A number of studies at home and abroad confirm that vibration agitation can significantly improve the micro-homogeneity of concrete and improve the strength and durability of concrete. In the construction of road construction,Industrial Agitator the stability of the stability of the soil directly affect the quality of road construction. Therefore, based on the stabilized soil forced mixing technology, this paper designs and manufactures the stabilized soil vibration mixer with 600t · h-1 as the vibration activating source, and compares it with the industrial experiment with ordinary forced stirring.

"Vibrating Stirring" is a means of agitating while stirring by means of additional vibrations. During the mixing process due to the presence of vibration, so that the mixture in a constant state of tremor, increasing the number of effective collision between particles, and promote the hydration of cement particles to improve the strength of the mixture. In addition, due to the action of vibration, the cohesion and internal friction between the mixes are reduced, the shear and convection effects of the mixing device are reduced,Industrial Agitator the stirring resistance is reduced, the mixing efficiency and the stirring process are improved stability. At the same time, the vibration of the aggregate surface also has a certain cleaning function, to strengthen the cement paste and aggregate between the bonding effect.

Industrial prototype is based on the existing continuous double horizontal shaft Industrial Agitator, the mixing device as a vibration activation source, the use of forced mixing and vibration strengthening method of combining the design and manufacture of stable soil vibration mixer industrial prototype.

The stirring device of the prototype is driven independently by the double motor, and then the synchronous gear is used to synchronize the reverse operation through the synchronous gear through the gear reducer, and the mixing device is put into the mixing tank. At the same time, the vibration transmission device adopts double The motor is driven independently and is transmitted to the exciter by means of a belt drive, which is directly connected to the agitator and transmits the vibration directly to the agitator so that both the stirring shaft, the stirring arm and the stirring blade vibrate, Stirring device forced mixing at the same time, also continue to accept the vibration effect, so that more fully stirred to improve the macro and micro uniformity of the mixture.

The main features of the industrial prototype are: the whole mixing device as a vibration activation source, stirring while stirring vibration, effective vibration area, only a small vibration intensity can make the mixture to get enough vibration to improve the The reliability of the machine.

The batching unit shall independently measure the aggregate of different particle size according to the grading requirements, and then deliver the measured aggregate to the stabilized soil vibration mixer through the aggregate belt conveyor. At the same time, the screw conveyor will powder The powder in the tank is transported to the industrial prototype. The water supply system also pumps the measured water into the industrial prototype. All the materials are continuously from the inlet to the discharge port in the industrial prototype, accepting the dual effect of forced stirring and additional vibration. The stirred mixture is conveyed into the finished material storage hopper through the conveyor belt conveyor below the outlet of the mixing tank for loading and transporting the transport vehicle to the site. All of the above control and feedback signals are controlled by the control system.
