A screening apparatus includes a vibrating screen assembly that includes a screen and a vibrating mechanism operable on the screen to cause vibration of the screen, the screen having a feed end and a discharge end. At least one shield member is positioned on the screen and is configured to cover part of the screen between the feed end of the screen and a position intermediate the feed and discharge ends of the screen, such that particulate material for screening by the screen can be fed on to the, or each, shield member, the, or each shield member being positioned on the screen so that a vibrational pattern of the screen is imparted to the shield member. An adjustment mechanism is operatively engaged with the, or each, shield member to adjust a position of a discharge end of the, or each, shield member relative to the discharge end of the screen.

The invention relates to a method comprising a device (1) having at least two separating surfaces (2, 2) for separating planar and three-dimensional solids, which can be light, medium, and heavy, wherein the device can be installed and integrated into existing system for separating different material streams, such as garbage and waste. The bulk goods (3) to be separated and fed first to a first separating surface (2), and then to a second separating surface (2) in succession, whereby a high degree of separation between light and heavy bulk goods (3) is achieved.

Disclosed herein is a system for detecting, removing, transferring and recovering an incompletely dried material. The system includes a transfer device transferring the material subjected to a drying process, a load cell measuring a weight of the material transferred through the transfer device, a material receiving unit receiving the measured material from the load cell when the weight of the measured material is higher than weights of other materials or a preset reference weight, a thermal imaging camera photographing the material received by the material receiving unit, an incompletely-dried-material determining unit acquiring temperature information of the material photographed by analyzing image data photographed by the thermal imaging camera, and determining whether the photographed material is an incompletely dried material based on the acquired temperature information, and an incompletely-dried-material receiving unit receiving the incompletely dried material from the material receiving unit.

Provided is a dry separation apparatus including: a main body; a first deck; a plurality of guides; a supply part; an air blow fan; and a vibration part. A dry separation method includes: supplying an object to be separated to a top surface of a first deck provided with a plurality of punches; sending, by an air blow fan, air to the punches (first punches); and horizontally vibrating, by a vibration part, the first deck so as to discharge particles which have different specific gravities of the object to be separated and a moveable force exerted by air passing the first punches through different passages.
