We are having a hard time unloading peanut hulls out of a hopper.
Initiating material flow in hoppers is what we do daily here at Martin Vibration Systems. For this application we would recommend mounting a linear non-impacting pneumatic vibrator such as the NTS™ Series 1/3 up the sloped section of your hopper. Due to our NTS vibrators being sized for each application, we will need to know the dimensions of the hopper’s sloped section, and the material’s bulk density. Examples of the NTS series of products being used in various industries can be seen on our website here.
