Static screens are widely used in coal preparation for desliming, dewatering, and sizing due to their simple operation, low cost, and compact design. However, traditional screens with stainless steel wedge bars face challenges such as material buildup, declining efficiency, frequent maintenance, and high operational costs.Derrick Corporation has introduced an innovative static screen featuring its third-generation surface technology, Trilogy™. This design improves feed distribution and operational efficiency by 10-30% compared to conventional sieve bends, as shown in the data presented in the paper. The new screens also maintain efficiency over time due to better wear characteristics of the synthetic material, which preserve sharp opening edges and support higher capacities through larger open areas and improved flow distribution.Lab tests and field trials in the U.S. have shown significant improvements in screen life, capacity, and profitability. This paper will present lab test data and case studies demonstrating the superior performance of Derrick's static screen technology.
