The most important thing is to understand the line thoroughly before implementing the extraction. Discuss the function of each machine and design the right suction product and suction performance for it. Nothing must be forgotten, starting from the material intake, filling points, conveyor belt overflows, crushers, classifiers, granulators. Each process section must be suctioned in its own specific way to avoid suctioning product instead of unwanted dust. Even one improperly designed or poorly regulated extraction point can mean a significant loss of the final product. Explosion hazardous environments must not be forgotten. By not being able to define the input material precisely, it must be assumed that explosive material may be sucked out and the whole technology must be adapted to this condition. The humidity of the medium to be extracted must not be forgotten. Especially in winter, condensation of humid air on the filter and hopper walls can occur inside the piping and filter equipment. The condensate causes the rotary feeder rails and the material inside the hopper to freeze. In order to prevent condensation, the filter system and the extraction piping must be thermally insulated and the hopper must be heated.
