Analysis on the causes of axle holding of concrete mixer

Guide: today's mixing station basically uses the forced concrete mixer, which has good mixing effect, high mixing efficiency, low noise and convenient operation. The forced concrete mixer is driven by the mixing shaft to mix the materials. In the mixing plant equipment, the concrete mixer as the main core component, determines the production efficiency of the whole mixing plant and the mixing quality of concrete. Today's mixing stations are basically forced concrete mixer, with good mixing effect, high mixing efficiency, low noise and convenient operation. The forced concrete mixer is driven by the mixing shaft to mix the materials. Therefore, the mixing shaft can also be said to be the main part of the concrete mixer. If the shaft holding phenomenon occurs, it may lead to the mixer and even the whole mixing station unable to run. So what is the reason that causes the concrete mixer to hold the shaft? After long-term experience summary, the main reasons are as follows. First of all, it may be the feeding position of raw materials. The main materials used in mixing concrete are sand aggregate, cement, fly ash, water and additives. If the raw material cement is wrapped with sand and stone and agglomerates in water, it is easy to stick to the mixing shaft if the mixing is not sufficient. If the direction of the cement inlet is unreasonable, the mixing shaft can not be stirred quickly and fully, and it is easy to form the shaft holding phenomenon. Then the main engine water inlet pipe and flushing position. If the position and direction of the flushing point are not correct, or the flushing pressure is too low, so that the concrete temporarily bonded on the shaft can not be washed off after the water enters into the main engine, and the shaft holding will be easily formed after a long time. In addition, the internal part of the mixer is not cleaned in time after the end of production, or the cleaning is not clean, resulting in the residual concrete on the surface of the mixing shaft, which will solidify on the mixing shaft after drying. If this is the case for a long time, it is very easy to produce the phenomenon of shaft holding.
