Abstract
Apparatus for continuously measuring the bulk density of particulate material such as cut tobacco comprising a measuring column with level detection and density indicating means, a weighing conveyor and control means for driving the conveyor at speeds determined by signals from the level detecting means.
Claims13
An apparatus for the continuous measurement of the bulk density of particulate material, comprising a conveyor, means for weighing particulate material on said conveyor, drive means for said conveyor, a measuring column disposed above said conveyor for delivering particulate material to said conveyor, input feeder means for particulate material to said measuring column, a level detection disposed adjacent said measuring column, density indicating means, and a controller for receiving signals from said level detector proportional to the level of the particulate material and for varying the speed of said drive means in dependance upon said signals to maintain a substantially constant level of material within the measuring column independent of variations of supply to said column;
- wherein the indicating means is controlled by signals from said weighing means.
