There are many kinds of mechanical fine screen on the market with different prices. Although the cost of mechanical fine screen is higher than that of artificial screens, it can reduce the intensity of manual labor and realize automatic control. There are many kinds of mechanical grille, and different kinds of characteristics and adaptive ranges are also different. 

One kind is the arm type mechanical fine screen, the medium depth broad mechanical fine screen, the maintenance is convenient, the life long structure is complex, the rake tooth and the grille is difficult to align; The other kind is the chain type mechanical fine screen, the depth is not big medium and small mechanical fine screen, mainly clears the long fiber, the belt structure is simple, the occupation area is small.

There are wire rope mechanical fine screen, suitable for large depth range of small and medium-sized grilles, wide scope of application, easy maintenance and corrosion protection requirements, maintenance need to stop water. There are rotary mechanical fine screen, which is a kind of small and medium-sized screens with small depth, simple structure, reliable operation, easy maintenance, light weight, high manufacturing requirements and large occupation area.  

When choosing the mechanical fine screen, we should consider the water quality, the flow rate through the grille, the location of the mechanical fine screen; the depth, width and the velocity of the flow through the grille; the installation angle and the height of the slag discharge; according to the water quality and the water depth, we can determine the material and type of the mechanical grille, and calculate the mechanical fine screen according to the flow rate, the flow rate through the screens and the installation angle. The width of the mechanical fine screen is also determined according to the location of the mechanical fine screen. http://www.khnwatertreatment.com/
