Due to the abrasion of concrete aggregate, the small mixer has been gradually replaced by the forced mixer due to its low efficiency. Small mixer is the mixing drum does not move, but forced by a number of sets of blades on the rotating shaft in the drum. When mixing, the blades rotate around the vertical axis or horizontal axis, and the materials are forced to mix until the mixing is even.

这种搅拌机的搅拌作用强烈，适宜于硬性混凝土和轻骨料混凝土，也可搅拌流动性混凝土，具有拌制质量好、搅拌速度快、生产效率高、操作简便及等优点;但动力消耗大，叶片磨损快，一般需用高强度合金钢或其他耐磨材料做内衬，多用于集中搅拌站。

This kind of mixer has strong mixing effect, which is suitable for hard concrete and light aggregate concrete, and can also mix flowing concrete. It has the advantages of good mixing quality, fast mixing speed, high production efficiency, simple operation and safety. However, it has large power consumption and quick wear of blades. Generally, it needs high strength alloy steel or other wear-resistant materials as lining, which is mostly used in centralized mixing station.

小型搅拌机的强制式搅拌机是一种多功能的搅拌机械，适用于质量较高的混凝土搅拌作业，是目前经济实惠的搅拌机械设备。强制式搅拌机因其具有质量轻、效率高、搅拌质量好，以及结构简单、操作方便等一系列特点而被迅速推广使用。

The forced mixer of small mixer is a kind of multi-functional mixing machine, which is suitable for high-quality concrete mixing operation, and is currently an economical and affordable mixing machinery and equipment. Forced mixer is widely used because of its light weight, high efficiency, good mixing quality, simple structure and convenient operation.
