Length grading of all granular materials. Cimbria indent cylinders serve the purpose of length grading of all granular resources such as wheat, Oat, Maize, Rice, Fine seeds, Lentils, Sticks from sunflower or sugar beet, Plastic particles etc., Together with for the extraction of unwanted short or long admixtures. Through the the granular, Inlet housing material to be graded flows into the interior of the turning cylinder whose cover is supplied with special deep drawn tear, Drop or spherical shaped pockets for the most precise length separation. The grains that embed themselves fully into the indents will be lifted following a certain distance fall external to the pockets under gravity into the trough and subsequently be discharged through the utilization of a conveying screw. The kernels which are longer than the indent diameter will immediately slide out and remain on the inside exterior of the indent cover. This shell product moves toward the discharge center of the cylinder and will be discharged into the outlet housing. Cimbria will be sizing the exact machine for the separation and capacity required. The selection of items consists also of large models which give the customer the opportunity to use fewer machines. The indented cylinder separators are supplied with rubber seals for preventing leakage and false feeding of seed individual drive, Into trough for each cylinder and maintenance, Free support bearings. The indented cylinder separators available in 10 different sizes with single cylinder throughput from 1 to 30 t/h.
