W.S. Tyler says its XL-Class vibrating screen combines advanced exciter drive technology with a wide body to offer better screening action and more throughput. Larger than the company’s other screens, the XL-Class is intended for high-tonnage production rates, yet is designed for low maintenance and easy operation. The screen offers a large 390-square-foot screening surface, allowing it to replace up to two inclined screens. This enables it to handle production rates up to 15,000 tons per hour and cut sizes from 1/4 to 5 inches with varying degrees of incline. The unit can also be configured as a banana screen. The decks are sloped to increase the speed of the material flow, which is especially effective when the feed load contains large amounts of fines smaller than the opening of the screen media. The screens are engineered using finite element analysis, which detects high vibration and stress points, natural frequencies, and harmonic responses, allowing each screen’s stroke, speed, and other variables to be set to perform at peak efficiency.
