Which type of spreader is known to create more dust when spreading granules?

Centrifugal spreaders are recognized for creating more dust when spreading granules due to their operational mechanism. These spreaders are designed to fling or spin granules outward from a revolving disk. This action not only disperses the material widely but can also cause an increase in airborne particles, leading to more dust generation. The centrifugal force plays a significant role in this dust creation, as the rapid rotation can cause granules to break apart or become airborne.

In contrast, handheld spreaders typically allow for more controlled application, minimizing dust output. Blower type spreaders, while also dispersing materials, generally use air to propel the product and may not generate as much dust compared to centrifugal action. Gravity-fed spreaders rely on gravity to move granules to the ground, resulting in less agitation and therefore less dust compared to the high-speed dispersal of a centrifugal spreader. Understanding the mechanics of these spreaders informs effective choice and usage in aquatic pest control scenarios.
