The mixing blades of large mixer are very important! The large mixer drives the mixing blade to rotate through the mixing shaft in the mixing drum, so as to complete the forced mixing of concrete. The quality of the mixing blade directly affects the mixing efficiency and quality of the concrete. When the large concrete mixer is selected, how to judge the mixing blade?

一、看材质。

1、 Look at the material.

大型搅拌车搅拌叶片磨损的速度与其使用的材质密切相关。一般来说，用废旧钢铁、边角料铸造而成的搅拌叶片，杂质多，使用寿命短，但较便宜；而采用优异钢板制作而成的搅拌叶片耐磨性更好，使用寿命长，相对较贵。像中科聚峰生产的大型搅拌车的搅拌叶片都是由完整钢板切割而成，当然搅拌效果更好。

The wear rate of the mixing blade of large mixer is closely related to the material used. Generally speaking, the mixing blades made of scrap steel and scrap are more impurities and shorter service life, but the price is lower; The mixing blade made of excellent steel plate has better wear resistance, long service life and relatively expensive price. For example, the mixing blades of the large mixer produced by zhongkejufeng are all cut from complete steel plate, and the mixing effect is better.
             

二、看加工。

2、 Look at the processing.

大型搅拌车搅拌叶片表面的加工质量决定了其使用时间的长短。如果只是简单的铸造打磨，搅拌叶片表面会粗糙不均匀，使用时容易断裂；假如通过专 业生产线对搅拌叶片表面进行加工处理，生产出来的搅拌叶片材质就会很均匀，表面顺滑，使用寿命也较长。

The quality of the surface of the mixing blade of the large mixer determines the length of its use time. If it is simply cast and polished, the surface of stirring blade will be rough and uneven, and it will break easily when used; If the surface of the mixing blade is processed through the professional production line, the material of the mixing blade will be very uniform, the surface is smooth and the service life is long.

大型搅拌车的使用时间长，而搅拌叶片又是主要的易磨损配件，所以提醒广大用户在选购过程中一定要细心观察搅拌叶片的材质和表面加工质量，一些大厂家均有自己的配件生产线，用户也可以亲自去参观一下。

The use of large mixer is long, and the mixing blade is the main wear-resistant accessories. Therefore, remind the users to carefully observe the material and surface processing quality of the mixing blade during the purchase process. Some large manufacturers have their own parts production line, and the user can also visit it in person.
