After the technical solution is finalized, the core task during the procurement phase is to avoid pitfalls and ensure value for money. The structure of a square swing screen is more complex than that of a traditional vibrating screen, so the following four key points require special attention during procurement.

Key Point 1: Examining the Rationality and Sturdiness of the Structural Design

The square gyratory screen box is subjected to constant reciprocating stress during operation, making structural sturdiness crucial.

Box Pitfall Inspection: Side Panel Thickness: Check whether the steel plate thickness of the screen box side panels is sufficient and whether they have reinforcing ribs. Weak structures are prone to cracking under long-term high loads. Welding Process: Check whether the welds are full, uniform, and free of voids. Excellent welding quality is the cornerstone of equipment longevity. Support Beam Design: Check whether the support beams inside the screen box are properly designed to effectively support the screen and reduce vibration deformation.

Key Point 2: Verify the Ease of Screen Tensioning and Replacement

The screen is a consumable part that requires frequent replacement. Poor design can make screen replacement a nightmare. Screen Pocket Avoidance Inspection: Request a demonstration. Ask the supplier to provide a video or on-site demonstration of screen replacement. Verify that the operation can be completed quickly without special tools. Tensioning effectiveness: Understand whether the tensioning system ensures uniform tension across the entire screen surface. Uneven tension can lead to premature localized breakage and poor screening performance.

Key Point 3: Evaluate the effectiveness of the sealing and anti-clogging screen design.

The four corners of a square gyratory screen present challenging sealing and cleaning challenges, and are a key indicator of the manufacturer's design capabilities.

Pocket Avoidance Inspection: Carefully examine the corner sealing structure of the equipment. Is it a simple rubber strip or a specialized sealing design? Feel the interior to check for obvious dead spots where material can accumulate. Regarding screen cleaning devices, inquire about the type of screen cleaning device used for materials prone to clogging. Common options include silicone rubber bouncing balls and ultrasonic screen cleaning systems. Ensure that the design effectively covers the entire screen surface, especially corners.

Key Point 4: Verify success stories and the reliability of after-sales support.

Pocket Avoidance Inspection: Request industry case studies. Insist that the supplier provide successful cases in your industry or with similar materials. Whenever possible, conduct an on-site or telephone inspection. A screen that performs well in a chemical plant may not necessarily handle grain well. Clearly specify after-sales service details in the contract, including warranty coverage, response time, and spare parts supply cycles (especially for consumable parts like screens). A responsible supplier will provide a clear after-sales guarantee plan.

For large equipment like the square gyratory screen, the best way to "judgment the performance, not the hype" is to conduct a trial run with material. Bring your actual material to the manufacturer and run the prototype continuously for a period of time. This provides the most intuitive way to verify the equipment's output, screening performance, noise level, powder leakage, and energy consumption, ensuring a well-founded and worry-free purchasing decision.
