The SCHULE circular screen is used in oat, wheat, rye, spelt, barley, maize, soya, pea, buckwheat, millet and rice mills as well as in silos for grain cleaning. The screens can be used to remove coarse and fine impurities from the grain as well as to classify products into different sizes.
By means of the separation method of screening, the uniformly fed product is divided into its various components. The coarse impurities remain on the surface of the upper screen, such as larger grains, wood and straw, while the product flow passes through the screen and reaches the lower screen.
The small impurities, such as sand, broken kernels and weed seeds, pass through the lower screen and, like the coarse impurities, are removed separately.
The overs of the lower screen are the main product. Optionally, the circular screen can be equipped with an aspiration channel and a magnet in which specifically lighter parts such as husks and dust are sucked off and metallic components are removed.
The circular screen is available in several sizes, thus excellent results can be achieved for a wide capacity range. The automatic cleaning of the screen by means of so-called tappers helps to achieve this. If required, the circular screen and the aspiration channel are also available in stainless steel design.
Advantages of the circular screen:
- Flexible application range
- Wide capacity range
- Automatic screen cleaning
In cleaning, the circular screen with aspiration channel is one of many machines, such as the dry stoner and the indented cylinder, for sorting out foreign impurities from the grain.
