When it comes to mixing powders and solids, there are a variety of mixing technologies that can be used. Two of the most common are plow mixers and paddle mixers. While these two types of mixers may seem similar on the surface, there are actually several key differences between them that can affect your choice of mixing technology.
Plow mixers are a type of industrial mixer that uses a horizontal, cylindrical drum and a set of plows mounted on a shaft.
Plow mixers are designed to mix powders and solids that are free-flowing, as well as those that have some degree of stickiness or agglomeration. The plows are designed to move the material from the center of the drum to the edges, and from the edges to the center, creating a rolling action that ensures thorough mixing. Plow mixers are a low shearing type of mixer and with the option of choppers can be more aggressive if needed.
Paddle mixers are another type of industrial mixer that uses a horizontal, cylindrical drum. However, paddle mixers use a set of paddles mounted on a shaft, rather than plows.
Paddle mixers are designed to mix powders and solids that are free-flowing, as well as those that are more cohesive or sticky. The paddles are designed to move the material in a radial direction, ensuring that all of the material is exposed to the mixing action. Paddle mixers are a no to low shear mixer which, like the plow mixer, can have choppers so when shearing is needed you can create this.
While both plow mixers and paddle mixers can be effective for mixing powders and solids, there are several key differences between them.
Choosing the right mixer for your application depends on a variety of factors, including the properties of the materials being mixed, the desired mixing intensity, and the required throughput.
By understanding the differences between plow mixers and paddle mixers, you can make an informed decision about which type of mixer is best for your specific application.
