Installation method: The YZS series circular vibrating screen must be installed on a sturdy concrete foundation. The foundation should be able to bear the weight of the equipment and the dynamic load during screening operation. During installation, ensure the foundation is level according to requirements, and anchor bolts should be tightened according to torque specifications. After the equipment is in place, adjust the leveling to ensure the screen box is parallel to the motor shaft. The motor and the exciter are connected via a belt or direct drive, and the belt tension or alignment must be adjusted to ensure smooth transmission. The spring supports must be installed vertically to ensure the correct vibration direction. After installation, conduct a no-load test run to check whether the screen box vibration is stable, if there is any abnormal noise, and to confirm that the amplitude and vibration frequency meet the requirements. The load test run should gradually increase the feed quantity to observe screening effects and motor current, ensuring it does not exceed the rated current. A dust removal system should be provided to reduce dust pollution. A central control system can be equipped for online monitoring and automatic control.

Selection Notes (Comparison with Linear Vibrating Screen and High-Frequency Vibrating Screen): The core difference between the YZS series circular vibrating screens and linear vibrating screens and high-frequency vibrating screens lies in:Movement trajectory, applicable materials, and processing capacity。 The YZS series circular vibrating screen uses a cylindrical eccentric shaft agitator and block adjustment amplitude. The body moves in a circular motion, resulting in long material sieve lines, multiple screening specifications, strong excitation force, and high screening efficiency. It is especially suitable for grading and screening medium and coarse materials in industries such as mines, sand and gravel yards, building materials, with a processing capacity of 50-2250 t/h. The linear vibrating screen uses a dual-axis exciter, allowing the material to move in a straight line, suitable for dehydration, deintermixing, and classification of fine materials. The high-frequency vibrating screen uses high-frequency excitation, suitable for fine particle material fine screens for fine screens and dehydration. For selection, for grading and screening medium and coarse materials, the YZS series circular vibrating screen is preferred; for fine material dehydration, linear vibrating screens are preferred; for fine particle fine screens, high-frequency vibrating screens are preferred.
