Circular motion screening machine

Our solution for classic applications

Circular motion screening machine

A SIEBTECHNIK circular motion screening machine is the classic solution for process engineering tasks in screen classification. They are free-swinging screening machines with a circular oscillating movement, which are mounted on air or helical compression springs.

Design variants

A SIEBTECHNIK circular motion screening machine is the classic solution for process engineering tasks in screen classification. They are free-swinging screening machines with a circular oscillating movement, which are mounted on air or helical compression springs. The mass ratios of the screen box and unbalance are optimally matched to each other. In this way, a harmonious oscillating movement can be transmitted to the screened material at all points of the screening machine. The speed and vibration amplitude of the machine can be varied to suit the specific product, thus ensuring a consistently perfect screening result. The robust design using and combining standard components ensures a high degree of flexibility and enables customer-oriented solutions. In addition, machines with low-maintenance running times and a long service life are created.

Our screening machines in the REKORD V (shaft with unbalance), VZ (cell drive) and VR (unbalance motor) series offer separation sizes from 0.8 to 300 mm and a screening surface of 0.5 to approx. 60 m². Depending on the product, the machines can be designed for a vibration amplitude of 2 – 14 mm. The screen bottom inclination is between 10° and 30°, depending on requirements, and the screen structure can comprise between one and three screen decks.

The screen box is designed to accommodate either longitudinally or transversely tensioned screen panels or flat screen panels and, of course, also for system screen panels from different screen panel manufacturers. For dusty screenings, we can supply circular vibrating screens with a dust hood or a closed dust protection box on request. Screening aids in the form of knocking devices or sprayers are also available as an option, individually adapted to your requirements.

Operating behavior & mechanical features

SIEBTECHNIK Circular-motion Screening Machines are free-swinging machines, which means that the diameter of the oscillating circuit is freely adjusted according to the mass ratio of the screen box and the unbalance. Circular vibrating screens have a steep throw angle and therefore require a screen bottom inclination of 10° to 18°. Exceptions are dewatering screens with an inclination of 3° to 5° and steep screens, e.g. sand screens with an inclination of 25° to 40°.

The screen box, consisting of side walls and cross beams, absorbs all static and dynamic forces. The drive shaft with the imbalances runs in two roller bearings, which are arranged in the center of gravity of the screen box. The screening machine is driven by V-belts or a flexible coupling. Larger screening machines are additionally equipped with a countershaft. The bearings are either oil or grease lubricated. The screen box is elastically supported on 4 spring elements against the substructure. It is designed to accommodate either longitudinally or transversely tensioned screen panels or flat screen panels. For dusty screenings, we can supply circular vibrating screens with a dust hood or a closed dust protection box on request.
