The three-dimensional multi-stage environmental protection screen is a new type of high standard screening device. This series of environmental protection screening machines is designed with advanced foreign design concepts, unique design, complete series spectrum, high screening accuracy, environmental protection and energy saving, fast replacement of screen mesh, negative pressure operation, good insulation, low noise and other characteristics. This series of screening machines currently has six specifications: GLSF1000-6000 series, with a screen surface that can achieve 4-6 layers, a screen hole size of 1.2-100mm to choose from, and a classification of 5-7 different materials. The special screen surface layout allows for higher screen utilization, fast switching of material classification, and simpler screen replacement. The processing capacity can reach 50-800t/h per hour. Compliant with the precise grading of sand and gravel aggregates and ultrafine granular materials, it can effectively meet the needs of environmentally friendly screening and grading for road asphalt mixing plants and building type machine-made sand systems.

This series of three-dimensional multi-level environmental protection screens adopts advanced design concepts and finite element force analysis calculation methods, and is equipped with advanced CNC machining, process and detection equipment. Each screening machine is equipped with an APP intelligent control system, which is interlocked with remote centralized control, online fault diagnosis and alarm, operation data collection and analysis, to ensure the quality and performance of the product and ensure the safe operation of the screening machine.
