Polygone sieve
The sieve drum is driven by the central shaft on the discharge side and mounted on the intake side by attenuated rollers running on the outer ring. This means that there are no restrictions to the material intake. The material being poured into the sieve first impacts on the raceway and then slides off onto the stainless steel sieve surfaces. The drum speed is monitored on the intake side by a sensor (IFM type IG5398). The sieve drum and the whole polygone sieve have a modular structure and can be expanded by adding up to four sieve rings each 1250 mm in row. As an option, catches can be fitted in the sieve drum which raise any lumps so that these disintegrate when they impact on the sieve surfaces. These catches can be set at a slant to extend the dwelling time of the product in the sieve. The base frame is lined with RCH1000 on the slanting
surfaces. The flanges for fine and coarse grains are within the foot plates to prevent collision of the connected chutes with the supports. The spring-mounted swivelling maintenance flaps automatically remain open and can be used on either side as a standard feature. In addition, there is a large-sized maintenance flap over the drive motor. In the upper cover, every segment is equipped with an exhaust air and a fresh air opening. One exhaust air opening has a pipe fitting of DN 250 mm and one fresh air opening is equipped with fully variable air flow control. The other openings are provided with blind flanges, but other fittings or controls can also be installed.
