The mixing quality of Zhongke Jufeng concrete mixer is closely related to mixing time besides raw materials and equipment. The mixing time of concrete mixer refers to the time from the completion of filling to the beginning of discharging, which can be determined according to the slump of mixing materials and the capacity of concrete mixer. Be sure to stir well.
一般混凝土搅拌机的搅拌时间为1-2分钟。用“净石法”搅拌约3分钟。混凝土搅拌机的搅拌时间较短。例如，JD200混凝土搅拌机可以使用30秒。能够。简而言之，它可以根据结构的实际情况通过实验来确定。坍落度(机械捣固1-2 cm，手动捣固2-4 cm)。与细砂混凝土混合可根据实际情况延长搅拌时间。
Generally, the mixing time of concrete mixer is 1-2 minutes. Stir with "clean stone method" for about 3 minutes. The mixing time of concrete mixer is short. For example, the jd200 concrete mixer can be used for 30 seconds. Can. In short, it can be determined by experiments according to the actual situation of the structure. Slump (mechanical tamping 1-2cm, manual tamping 2-4cm). Mixing with fine sand concrete can prolong the mixing time according to the actual situation.
Installation of concrete mixing blades: the angle of concrete mixing blades shall be the same and shall not be reversed. If the tilt angle of the mixing blade is too large or too small, it will affect the mixing yield, so the tilt angle between the blade and the mixing shaft can be about 70 or 80 degrees. The preferred angle of the mixing blade is rotated to the upper part, exposing 20-30mm of mud. The phase of the mixing blades on both shafts shall be offset by 90 degrees from the phase of the paint; when installing the mixing blades, they shall be tightened. Tighten the nut on the mixing blade.
The main cause of blade damage of concrete mixer is blade wear. At this time, the cutting torch needs to cut the edge of the blade for wear, and then use the steel plate with the same thickness of the blade to cut into the required size; the petiole is bent. Or fracture, two reasons are: the petiole is not strong enough, then increase the diameter of the petiole, and use round steel; the petiole material is fragile, and can be changed to ordinary round steel.
