A gravimetric blender
A Gravimetric blender a type of device used in material handling and processing applications to blend and dispense precise amounts of multiple materials. It is commonly used in the plastics industry to accurately blend plastic pellets of different colors or additives.
The gravimetric blender operates on the principle of weight measurement, where each material is weighed individually before being dispensed into a common mixing chamber. The weight measurements are controlled by a computerized system that ensures precise proportions of each material are dispensed according to a pre-programmed recipe.
The materials are then mixed together in the mixing chamber, creating a homogeneous blend that can be dispensed for use in a variety of applications. Gravimetric blenders are preferred over other types of blenders because they offer more precise control over the amount of each material being used, resulting in a more consistent blend and better overall product quality.
The gravimetric blender operates by accurately measuring the weight of each material to be blended and then automatically adjusting the flow rate of each material to achieve the desired ratio. The materials are typically fed into the blender from individual hoppers, which can be refilled as needed.
