The broken kernel screener is mainly used to separating the different type of broken kernels which were from sheller processing operation. It is often placed behind the shelling production line for broken kernel control and perfect kernel rate improvement of finished products, and achieve higher market value. Automatic cleaning procedure adopts dual vibrating motor, rubble balls and one piece of high density sieve. For materials quality standard, build of these screens are available both in carbon and stainless steel. In the kernel processing line, it is an important component with simple structure and efficient screening operation.
