MODEL SELECTION GUIDE
The model and the quantity having the optimum impact force are selected according to the type, the shape, the size, and clinging and blocking condition in silo, hopper etc.
For instance, when installing on the conical hopper of 1,200mm (47 inch) dia. 3.2mm (0.126 inch) thick, find the point of intersection X according to the figure below. As the point X is within the range of RKV40 2 nos, and RKV60 2 nos, select RKV40 2 nos, for small clinging strength, and RKV60 2 nos, for large clinging strength.
