A vibrating screen that uses a bar screen is called a bar vibrating screen, whatever it is a linear screen or a circular vibrating screen. The bars can be made of manganese steel bars, guide rails, stainless steel bars and other different materials, and the net cleaning effect can be achieved through different structures. The bar screen is suitable for feeding of large pieces of material in front of the crusher, and is especially suitable for the feeding of metal ore, construction stone, coarse crushing or intermediate crushing. The gap between the rods is adjustable, which can separate the soil and fine materials while feeding, effectively exerting the function of the subsequent crusher. The bar screen has the characteristics of simple structure, convenient maintenance, high strength, impact resistance, abrasion resistance, and low noise.
