Steel frame screens are mostly applied to the shale shakers with wedge fastening equipment. The screen frames adopt that high-strength square steel tube welded to multi-ribbed construction. They are sturdy and reliable. These screens are constructed with two or three stainless steel layers bonded to a steel support plank. Accessary rubber plugs may be used to repair rips or tears. By doing this, we can cut down time and reduce the production costs. We can supply steel frame screens with mesh sizes ranging from 20 to 250. Steel frame screen is in common used presently, that are constructed mostly withe two or three stainless steel layers bonded tightly to the steel frame.The frame is made up of the high-strength square steel tube or flat steel welded to multi- ribbed construction.These layers are coupled with the frame through metal backing plate or bonded straightly as well.We possess the strong experience and the ripe technology,and will provide various specifications of steel frame screens to serve the clients' demands. Features of Steel frame screen 1. Different layers with different density. To arrange these layers reasonably and exactly, the screening effect will become more and better. 2.High strength frame, multi-ribs and the mesh cloth with moderate tension , from one reliable combination , which can increase screen�??s acceptable flow , the intensity and the lifetime 3.The wedge-shaped fastening device, can make the erection of screens more handily and quickly 4.The mesh divided into many independent small units by grids of the backing plate ,can prevent rips or tears from spreading overmuch. Accessory prepared rubber stoppers can be used to repair damage. By doing so, the operator can cut down the stop time and reduce the cost.
