Continuous Loss-in-Weight Blenders 

Chapter 3: Installation 

29 

This section will discuss the mechanical setup and control system setup of the continuous 
loss-in-weight blending system. After reading this section, you should be familiar with the 
mechanical setup and the electronic control setup of the blending system. 

The mechanical setup of the continuous loss-in-weight blending system involves the 
adjustment of the weigh hopper load cells (Please refer to the figure below). This figure 
illustrates the proper adjustment of the load cell mechanical stop bolt. The setting for the 
positive stop is necessary to prevent the load cell from being “over-ranged” by excessive 
loading on the weigh hopper. The setting for the load cell stop is forty thousandths of an inch 
maximum (.040”). This should be set by a feeler thickness gauge with the weigh hopper 
empty. 

If a feeler gauge is not available, the weigh hopper should be filled with the material that is to 
be blended, and the stop adjusted so there is just a very small gap (a couple of sheets of 
notebook paper) between the load cell, and the blender base stop. This will allow the load cell 
to operate without mechanical restrictions and provide an overload safety. To adjust the stop, 
adjust the screw located on the bottom of the load cell. Adjust the screw up to increase the 
gap and down to decrease the gap.
