Features:
1, high strength. V-shaped cross-sectional height greater than the width of the screen, mesh strip itself has a certain strength. The screen bars in contact with the support bar of each point is fixed by welding, so that all the screen bars to form a solid whole.
2, the opening rate. Opening rate is generally porous plate does not exceed 30%, since the opening hole bridge between a certain width, but Johnson network is not so limited, the hole is to bridge Johnson sieve mesh strips, Since the processing method and the cross-sectional shape of the screen to make it easy to break, can take all spans a relatively narrow size, reducing the width of the screen bars or expanded gap between the screen bars, the opening ratio can be improved Johnson network.3, clogging resistance. V-screen bar arranged together, viewed in cross section, opening for the bell, once crushed catalyst particles pass through the sieve of slits, then the fluid will be taken away, because the particles in contact with the edge of the screen bars only two points in the screen the possibility of small slits jammed. Pores of the porous plate in contact with the edge of the larger particles, the particles can be jammed willing phenomenon occurs.
4, can filter fine particles. Johnson mesh sieve gap can be controlled by the degree of density between the strips arranged screen bars. Lerner company computer numerical control to modulate the gap, minimum clearance of 15 microns can be done.
Usage: Johnson nets are widely used for drainage, chemical and petrochemical processes, mining, paper and food processing equipment such as chemical and petrochemical plants in the fixed bed reactor is one of its main purposes, can be used in the shaft the reactor (flat type) can also be used in the radial reactor (cylindrical) Johnson nets many varieties and specifications can be customized according to customer requirements. Lehler company designed and manufactured according to customer requirements)
