要求自动搅拌车骨料粉的下落点在自动搅拌车的中心，避开两个搅拌轴。今天就简单了解下搅拌机低效区在工作中有什么现象效果？

It is required that the falling point of the aggregate powder of the automatic mixer is in the center of the automatic mixer, avoiding the two mixing shafts. Today, let's briefly understand the phenomenon and effect of mixer low efficiency area in work?

在低效区，混合料运动缓慢，相间对流渗透不剧烈，容易使混合料粘在搅拌轴上，产生“抱轴”现象.振动搅拌法、工作装置优化法、双排搅拌叶片结构等方法可有效搅拌的低效率区。

In the low efficiency area, the mixture moves slowly and the convection and infiltration between phases are not violent, which is easy to make the mixture stick to the mixing shaft and produce the phenomenon of "holding the shaft" Vibration mixing method, working device optimization method and double row mixing blade structure can effectively eliminate the low efficiency area of mixing.

搅拌低效区，靠近搅拌轴端部搅拌臂线速度过低。为了防止混凝土离析，搅拌叶片的线速度应限制在搅拌臂外端的值。这样，在靠近搅拌轴的一端，由于线速度较低，形成了搅拌效率低下甚死区。

Eliminate the inefficient mixing area, and the linear speed of the mixing arm near the end of the mixing shaft is too low. In order to prevent concrete segregation, the linear speed of the mixing blade shall be limited to the maximum value at the outer end of the mixing arm. In this way, at the end close to the mixing shaft, due to the low linear speed, the mixing efficiency is low or even dead zone is formed.

移动式混凝土强制搅拌机需要在路面上不断转动风机叶片，才能达到防止混凝土离析的效果。这种大型水泥搅拌车对于司机来说可不简单。

The mobile concrete forced mixer needs to continuously rotate the fan blade on the road to achieve the effect of preventing concrete segregation. This large professional cement mixer is not simple for drivers.

搅拌车在搅拌混凝土时，将物料装入搅拌筒时，通常先装入冲击力较小的混合料，再对搅拌筒进行操作。使用手柄时，不要移动太快或太猛烈。

When the mixer truck mixes concrete, when loading materials into the mixing drum, it usually loads the mixture with less impact first, and then operates the mixing drum. When using the handle, do not move too fast or too violently.

在倒车移动混凝土强制搅拌机之前调查地形。驾车经过停车位时，应注意空位周围是否有障碍物。

Investigate the terrain before reversing the concrete forced mixer. When driving past the parking space, pay attention to whether there are obstacles around the empty space.

停车和倒车时，越往后越往前，越容易停车，尤其是停车位太小，否则可能无法停车。新手请注意这一点，因为中级骑手会提高可用技能。

When parking and reversing, it is easier to stop the car as you move backward and forward, especially if the parking space is too small, otherwise you may not be able to stop. Novices should pay attention to this because intermediate riders will improve available skills.

搅拌机在空载运行和混凝土输送过程中，搅拌筒不得停止转动，以免造成滚道和滚筒的局部损坏或混凝土离析。

During the no-load operation and concrete transportation of the mobile concrete forced mixer, the mixing drum shall not stop rotating, so as to avoid local damage to the raceway and drum or concrete segregation.
